A mass spectrometry technique used for analysis of nonvolatile compounds such as proteins and macromolecules. The technique involves preparing electrically charged droplets from analyte molecules dissolved in solvent. The electrically charged droplets enter a vacuum chamber where the solvent is evaporated. Evaporation of solvent reduces the droplet size, thereby increasing the coulombic repulsion within the droplet. As the charged droplets get smaller, the excess charge within them causes them to disintegrate and release analyte molecules. The volatilized analyte molecules are then analyzed by mass spectrometry.

Activation of c-Abl tyrosine kinase requires caspase activation and is not involved in JNK/SAPK activation during apoptosis of human monocytic leukemia U937 cells. (1/7204)

Genotoxic stress triggers the activation of several sensor molecules, such as p53, JNK1/SAPK and c-Abl, and occasionally promotes the cells to apoptosis. We previously reported that JNK1/SAPK regulates genotoxic stress-induced apoptosis in p53-negative U937 cells by activating caspases. c-Abl is expected to act upstream of JNK1/SAPK activation upon treatment with genotoxic stressors, but its involvement in apoptosis development is still unclear. We herein investigated the kinase activities of c-Abl and JNK1/SAPK during apoptosis elicited by genotoxic anticancer drugs and tumor necrosis factor (TNF) in U937 cells and their apoptosis-resistant variant UK711 cells. We found that the activation of JNK1/SAPK and c-Abl correlated well with apoptosis development in these cell lines. Unexpectedly, however, the JNK1/SAPK activation preceded the c-Abl activation. Moreover, the caspase inhibitor Z-Asp suppressed c-Abl activation and the onset of apoptosis but not the JNK1/SAPK activation. Interestingly, c-Abl tyrosine kinase inhibition by CGP 57148 reduced apoptosis without interfering with JNK1/SAPK activation. These results indicate that c-Abl acts not upstream of JNK1/ SAPK but downstream of caspases during the development of p53-independent apoptosis and is possibly involved in accelerating execution of the cell death pathway.  (+info)

Plasticity of first-order sensory synapses: interactions between homosynaptic long-term potentiation and heterosynaptically evoked dopaminergic potentiation. (2/7204)

Persistent potentiations of the chemical and electrotonic components of the eighth nerve (NVIII) EPSP recorded in vivo in the goldfish reticulospinal neuron, the Mauthner cell, can be evoked by afferent tetanization or local dendritic application of an endogenous transmitter, dopamine (3-hydroxytyramine). These modifications are attributable to the activation of distinct intracellular kinase cascades. Although dopamine-evoked potentiation (DEP) is mediated by the cAMP-dependent protein kinase (PKA), tetanization most likely activates a Ca2+-dependent protein kinase via an increased intracellular Ca2+ concentration. We present evidence that the eighth nerve tetanus that induces LTP does not act by triggering dopamine release, because it is evoked in the presence of a broad spectrum of dopamine antagonists. To test for interactions between these pathways, we applied the potentiating paradigms sequentially. When dopamine was applied first, tetanization produced additional potentiation of the mixed synaptic response, but when the sequence was reversed, DEP was occluded, indicating that the synapses potentiated by the two procedures belong to the same or overlapping populations. Experiments were conducted to determine interactions between the underlying regulatory mechanisms and the level of their convergence. Inhibiting PKA does not impede tetanus-induced LTP, and chelating postsynaptic Ca2+ with BAPTA does not block DEP, indicating that the initial steps of the induction processes are independent. Pharmacological and voltage-clamp analyses indicate that the two pathways converge on functional AMPA/kainate receptors for the chemically mediated EPSP and gap junctions for the electrotonic component or at intermediaries common to both pathways. A cellular model incorporating these interactions is proposed on the basis of differential modulation of synaptic responses via receptor-protein phosphorylation.  (+info)

Low resting potential and postnatal upregulation of NMDA receptors may cause Cajal-Retzius cell death. (3/7204)

Using in situ patch-clamp techniques in rat telencephalic slices, we have followed resting potential (RP) properties and the functional expression of NMDA receptors in neocortical Cajal-Retzius (CR) cells from embryonic day 18 to postnatal day 13, the time around which these cells normally disappear. We find that throughout their lives CR cells have a relatively depolarized RP (approximately -50 mV), which can be made more hyperpolarized (approximately -70 mV) by stimulation of the Na/K pump with intracellular ATP. The NMDA receptors of CR cells are subjected to intense postnatal upregulation, but their similar properties (EC50, Hill number, sensitivity to antagonists, conductance, and kinetics) throughout development suggest that their subunit composition remains relatively homogeneous. The low RP of CR cells is within a range that allows for the relief of NMDA channels from Mg2+ blockade. Our findings are consistent with the hypothesis that CR cells may degenerate and die subsequent to uncontrolled overload of intracellular Ca2+ via NMDA receptor activation by ambient glutamate. In support of this hypothesis we have obtained evidence showing the protection of CR cells via in vivo blockade of NMDA receptors with dizocilpine.  (+info)

Ischemic tolerance in murine cortical cell culture: critical role for NMDA receptors. (4/7204)

Murine cortical cultures containing both neurons and glia (days in vitro 13-15) were exposed to periods of oxygen-glucose deprivation (5-30 min) too brief to induce neuronal death. Cultures "preconditioned" by sublethal oxygen-glucose deprivation exhibited 30-50% less neuronal death than controls when exposed to a 45-55 min period of oxygen-glucose deprivation 24 hr later. This preconditioning-induced neuroprotection was specific in that neuronal death induced by exposure to excitotoxins or to staurosporine was not attenuated. Neuroprotection was lost if the time between the preconditioning and severe insult were decreased to 7 hr or increased to 72 hr and was blocked if the NMDA antagonist 100 microM 3-((D)-2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid was applied during the preconditioning insult. This was true even if the duration of preconditioning was increased as far as possible (while still remaining sublethal). A similar preconditioning effect was also produced by sublethal exposure to high K+, glutamate, or NMDA but not to kainate or trans-1-aminocyclopentane-1, 3-dicarboxylic acid.  (+info)

Modulation of basal intracellular calcium by inverse agonists and phorbol myristate acetate in rat-1 fibroblasts stably expressing alpha1d-adrenoceptors. (5/7204)

In rat-1 fibroblasts stably expressing alpha1d-adrenoceptors BMY 7378, phentolamine, chloroethylclonidine and 5-methyl urapidil decreased basal [Ca2+]i. WB 4101 induced a very small effect on this parameter but when added before the other antagonists it blocked their effect. All these agents inhibited the action of norepinephrine. Phorbol myristate acetate also blocked the effect of norepinephrine and decreased basal [Ca2+]i. Staurosporine inhibited these effects of the phorbol ester. Our results suggest that: (1) alpha1d-adrenoceptors exhibit spontaneous ligand-independent activity, (2) BMY 7378, phentolamine, chloroethylclonidine and 5-methyl urapidil act as inverse agonists and (3) protein kinase C activation blocks spontaneous and agonist-stimulated alpha1d-adrenoceptor activity.  (+info)

Acquisition of nicotine discrimination and discriminative stimulus effects of nicotine in rats chronically exposed to caffeine. (6/7204)

Caffeine and nicotine are the main psychoactive ingredients of coffee and tobacco, with a high frequency of concurrent use in humans. This study examined the effects of chronic caffeine exposure on 1) rates of acquisition of a nicotine discrimination (0.1 or 0.4 mg/kg, s.c., training doses) and 2) the pharmacological characteristics of the established nicotine discrimination in male Sprague-Dawley rats. Once rats learned to lever-press reliably under a fixed ratio of 10 schedule for food pellets, they were randomly divided into two groups; 12 animals were maintained continuously on caffeine added to the drinking water (3 mg/ml) and another 12 control rats continued to drink tap water. In each group of water- and caffeine-drinking rats, there were six rats trained to discriminate 0.1 mg/kg of nicotine from saline and six rats trained to discriminate 0.4 mg/kg of nicotine from saline. Regardless of the training dose of nicotine, both water- and caffeine-drinking groups required a comparable number of training sessions to attain reliable stimulus control, although there was a trend for a slower acquisition in the caffeine-drinking group trained with 0.1 mg/kg of nicotine. Tests for generalization to different doses of nicotine revealed no significant differences in potency of nicotine between water- and caffeine-drinking groups. The nicotinic-receptor antagonist mecamylamine blocked the discriminative effects of 0.1 and 0.4 mg/kg nicotine with comparable potency and efficacy in water- and caffeine-drinking groups. There was a dose-related generalization to both the 0.1 and 0.4 mg/kg nicotine cue (maximum average of 51-83%) in water-drinking rats after i.p. treatment with d-amphetamine, cocaine, the selective dopamine uptake inhibitor GBR-12909, apomorphine, and the selective dopamine D1 receptor agonist SKF-82958, but not in caffeine-drinking rats (0-22%). There was no generalization to the nicotine cues after i.p. treatment with caffeine or the selective D2 (NPA) and D3 (PD 128,907) dopamine-receptor agonists in water- and caffeine-drinking rats. The dopamine-release inhibitor CGS 10746B reduced the discriminative effects of 0.4 mg/kg nicotine in water-drinking rats, but not in caffeine-drinking rats. There was no evidence of development of tolerance or sensitization to nicotine's effects throughout the study. In conclusion, chronic caffeine exposure (average, 135 mg/kg/day) did not affect the rate of acquisition of the nicotine discrimination, but it did reduce the dopaminergic component of the nicotine-discriminative cue. The reduction of the dopaminergic component of the nicotine cue was permanent, as this effect was still evident after the caffeine solution was replaced with water in caffeine-drinking rats. That nicotine could reliably serve as a discriminative stimulus in the absence of the dopaminergic component of its discriminative cue may differentiate nicotine from "classical dopaminergic" drugs of abuse such as cocaine and amphetamine.  (+info)

Selective antiaggressive effects of alnespirone in resident-intruder test are mediated via 5-hydroxytryptamine1A receptors: A comparative pharmacological study with 8-hydroxy-2-dipropylaminotetralin, ipsapirone, buspirone, eltoprazine, and WAY-100635. (7/7204)

The present study characterized the effects of the novel, selective, and potent 5-hydroxytryptamine1A (serotonin) (5-HT1A) receptor agonist, alnespirone [S-20499, (S)-N-4-[5-methoxychroman-3-yl)propylamino)butyl- 8-azaspiro-(4,5)-diacetamide, hydrochloride] on offensive and defensive resident-intruder aggression in wild-type rats and compared its actions with those of the prototypical full 5-HT1A agonist 8-hydroxy-2- dipropylaminotetralin (8-OH-DPAT), the partial 5-HT1A agonists ipsapirone and buspirone, and the mixed 5-HT1A/1B agonist eltoprazine. All five agonists exerted effective dose-dependent decreases of offensive aggressive behavior in resident rats; 8-OH-DPAT was the most potent (ID50 = 0.074 mg/kg), followed by eltoprazine (0.24), buspirone (0.72), ipsapirone (1.08), and alnespirone (1.24). However, in terms of selectivity of the antiaggressive effects as determined by the absence of decrements in social interest and general motor activity, alnespirone appeared to be superior. In the defensive aggression test, neither alnespirone nor any of the other four agonists changed defensive behaviors in the intruder rats. The involvement of 5-HT1A receptors in the antiaggressive actions of these drugs was confirmed by showing that the selective 5-HT1A receptor antagonist WAY-100635 (N-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-N-(2- pyridinyl)cyclohexanecarboxamide trihydrochloride), which was inactive alone, fully prevented the antiaggressive effects of alnespirone, 8-OH-DPAT, and buspirone and partly reversed those of ipsapirone and eltoprazine. The data clearly indicate that alnespirone effectively suppresses offensive aggression with an advantageous profile of action compared with other full or partial 5-HT1A agonists. These selective antiaggressive actions of alnespirone are mediated by stimulating 5-HT1A receptors, presumably the somatodendritic autoreceptors at the raphe nuclei. Furthermore, the data provide evidence for a major involvement of these 5-HT1A receptors in the modulation of aggressive behavior by 8-OH-DPAT, ipsapirone, buspirone, and eltoprazine.  (+info)

Inhibition of human immunodeficiency virus type 1 replication by combination of transcription inhibitor K-12 and other antiretroviral agents in acutely and chronically infected cells. (8/7204)

8-Difluoromethoxy-1-ethyl-6-fluoro-1,4-dihydro-7-[4-(2-methoxyp hen yl)-1- piperazinyl]-4-oxoquinoline-3-carboxylic acid (K-12) has recently been identified as a potent and selective inhibitor of human immunodeficiency virus type 1 (HIV-1) transcription. In this study, we examined several combinations of K-12 and other antiretroviral agents for their inhibitory effects on HIV-1 replication in acutely and chronically infected cell cultures. Combinations of K-12 and a reverse transcriptase (RT) inhibitor, either zidovudine, lamivudine, or nevirapine, synergistically inhibited HIV-1 replication in acutely infected MT-4 cells. The combination of K-12 and the protease inhibitor nelfinavir (NFV) also synergistically inhibited HIV-1, whereas the synergism of this combination was weaker than that of the combinations with the RT inhibitors. K-12 did not enhance the cytotoxicities of RT and protease inhibitors. Synergism of the combinations was also observed in acutely infected peripheral blood mononuclear cells. The combination of K-12 and cepharanthine, a nuclear factor kappa B inhibitor, synergistically inhibited HIV-1 production in tumor necrosis factor alpha-stimulated U1 cells, a promonocytic cell line chronically infected with the virus. In contrast, additive inhibition was observed for the combination of K-12 and NFV. These results indicate that the combinations of K-12 and clinically available antiretroviral agents may have potential as chemotherapeutic modalities for the treatment of HIV-1 infection.  (+info)

Application Notes: Piperazine is an organic hydrophilic basic compound containing two secondary amines. It is not retained on traditional reversed-phase columns without ion pairing reagent. Since piperazine is not UV active, alternative detection techniques like ELSD, CAD and LC/MS must be employed. Two fast methods of analysis on Primesep 100 and 200 columns were developed using reversed-phase cation-exchange approach.

Piperazine is an amine which is used both as an activator or promoter, but also as active component in CO2 capture solvents. High concentrations are being formulated to draw benefit of the PZ properties. This results in a risk of precipitation of PZ and other solid phases during capture. It could be a benefit to the capture process, but it could also result in unforeseen situations of potential hazardous operation, clogging, equipment failure etc.Security of the PZ process needs to be in focus. Flow assurance requires additional attention, especially due to the precipitation phenomenon. This entails all parts of the streams, but also during formulation and transport of the solvent.In this work the extended UNIQUAC thermodynamic model is presented with the addition of piperazine (PZ or PIPH2) in combination with the potassium ion of mixtures with CO2 in equilibration with KOH-KHCO3-K2CO3. Phase boundaries are laid out which shows the concentration regions of solid formation. A special focus will ...

Finally theres a reagent that can detect phenylpiperazines such as mCPP and TfMPP: EZ Test mCPP.. A global shortage of the major precursor that is used for the production of MDMA, PMK or MDP2P, made unscrupulous producers look for other substances that could be sold.. They flooded the market with pills that were made with this stuff. MCPP and other piperazines have nothing to do with Ecstasy, nor do these substances have any of the effects that makes Ecstasy so special. Luckily theres a possibility to weed these nasty buggers out!. As a bonus this test kit also reacts to 6-APB, which goes burgundy red. Although the samples that were used for this could not be verified by lab, due to a lack of a standard reference sample, they came from a very reputable source.

OUTLINE: This is a multicenter, dose-escalation study of imatinib mesylate and cytarabine.. Patients receive oral imatinib mesylate alone once daily on days 1-21. Patients then receive oral imatinib mesylate once daily and cytarabine IV over 1-3 hours on days 1-7. Combination therapy repeats every 28-42 days for 2 courses. Patients then receive maintenance oral imatinib mesylate once daily. Treatment continues in the absence of disease progression or unacceptable toxicity.. Cohorts of 5-20 patients receive escalating doses of imatinib mesylate and cytarabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 5/5, 5/10, or 5/20 patients experience dose-limiting toxicity.. Patients are followed every 6 months.. PROJECTED ACCRUAL: A total of 30-60 patients will be accrued for this study within 2 years. ...

The t(9;22) translocation is seen in cases of chronic myeloid leukemia (CML), a subset of acute lymphocytic leukemia (ALL) and rarely in acute myeloid leukemia (AML). The resulting BCR-ABL fusion gene is transcribed and translated into a 210 kD (p210, major transcript) or 190 kD (p190, minor transcript) BCR-ABL fusion product with dysregulated (significantly enhanced) tyrosine kinase activity. Detection of the BCR/ABL1 fusion gene transcript is a critical determinant in diagnosis. The BCR/ABL1 fusion gene product is the cause of disease and growth of leukemic cells and expression levels of the transcript are directly related to disease severity. The use of new drugs for treatment such as the tyrosine kinase inhibitor imatinib mesylate (Gleevec) reduces the amount of leukemic cells below the level of cytogenetic detection and therefore makes molecular determination in the detection of minimal residual disease desirable. A consensus treatment goal is the achievement of major molecular response, ...
In the presence of imatinib mesylate, both age groups displayed little change in spontaneous slow-wave activity with the exception of the highest concentration (Fig. 2ii). A major difference between the two age groups occurred in the amplitude of contractile activity at all concentrations of imatinib mesylate. In the ageing guinea-pig prostate, a concentration-dependent inhibition was seen where low concentrations of imatinib mesylate produced the most inhibition whereas high concentrations produced less inhibition of contractile activity.. In contrast, contractile amplitude was generally reduced to 26-40% across all concentrations in the younger guinea-pig prostate. This difference between age groups may parallel the reduction in pacemaker potential activity and increase in spike potential activity with age, which was previously observed by Dey et al. [14]. Like the guinea-pig bladder [16], the guinea-pig prostate generates nifedipine-sensitive spike potentials, as well as slow-wave activity. ...

BACKROUND: The selective tyrosine kinase inhibitor imatinib inhibits growth of bcr/abl positive cells and, thus, has become a novel therapeutic option for the treatment of Ph+ leukaemic patients. Various mutations within the abl sequence have been described that prevent adequate imatinib binding to bcr/abl resulting in cellular resistance of CML cells. METHODS: We investigated 69 CML patients under treatment with imatinib as part of an ongoing clinical trial. At recruitment 37 patients were in chronic phase, 21 patients in accelerated phase and 11 patients in blast crisis. Bcr/abl, WT1, MDR1and AGP RNA transcripts were quantified in peripheral leucocytes by real time PCR. AGP protein levels in plasma were measured by turbidimetric analysis. By combining peptide nucleic acid (PNA) based DNA clamping with a fluorescence hybridisation probe assay we developed a new and highly sensitive technique for the detection of known mutations within the bcr/abl kinase domain. RESULTS: 1. Our results ...
The clinical success of the ABL tyrosine kinase inhibitor imatinib in chronic myeloid leukaemia (CML) serves as a model for molecularly targeted therapy of cancer, but at least two critical questions remain. Can imatinib eradicate leukaemic stem cells? What are the dynamics of relapse due to imatinib resistance, which is caused by mutations in the ABL kinase domain? The precise understanding of how imatinib exerts its therapeutic effect in CML and the ability to measure disease burden by quantitative polymerase chain reaction provide an opportunity to develop a mathematical approach. We find that a four-compartment model, based on the known biology of haematopoietic differentiation, can explain the kinetics of the molecular response to imatinib in a 169-patient data set. Successful therapy leads to a biphasic exponential decline of leukaemic cells. The first slope of 0.05 per day represents the turnover rate of differentiated leukaemic cells, while the second slope of 0.008 per day represents ...
Imatinib (STI571 or Gleevec) is a small-molecule inhibitor of the BCR-ABL tyrosine kinase that produces clinical remissions in chronic myeloid leukemia (CML) patients with minimal toxicity (1, 2). Imatinib is now frontline therapy for CML, but resistance is increasingly encountered. Clinical resistance is primarily mediated by mutations within the kinase domain of BCR-ABL and, to a lesser extent, by amplification of the BCR-ABL genomic locus (3). Crystallographic studies revealed that imatinib binds to the adenosine triphosphate (ATP)-binding site of ABL only when the activation loop of the kinase is closed and thus stabilizes the protein in this inactive conformation (4). In addition, the normally smooth contour of the phosphate-binding loop of ABL is distorted by imatinib binding, adding further to the unique conformational requirements for optimal kinase inhibition. These conformation-specific binding requirements contribute to imatinibs selectivity, particularly with regard to the closely ...

Benign prostatic hyperplasia (BPH) is a common disease in aging males and a substantial percentage of men with BPH develop a bladder obstruction. The obstruction caused by BPH is thought to be attributable to two main components i.e. a static component related to enlarged prostatic tissue mass and a dynamic component involving excessive contraction of prostate and urethra. The most successful therapies are based on a-adrenergic receptor antagonism and androgen levels modulation by 5a-reductase inhibitors. 5a-reductase inhibitors are of limited effectiveness in terms of immediate symptomatic and urodynamic relief. ai-adrenergic receptors antagonists appear to be much more effective and provide immediate subjective symptomatic improvements and are, therefore, the preferred modalities of treatment in the control of symptoms of benign prostatic hyperplasia. ai-Adrenoceptors are also present in blood vessels and play an important role in the regulation of blood pressure. Thus ai-adrenoceptor ...

An Open Label, Multi-center Imatinib Roll-over Protocol for Patients Who Have Completed a Previous Novartis-sponsored Imatinib Study and Are Judged by the Investigator to Benefit From Continued Imatinib Treatment
Imatinib has shown remarkable clinical benefit for treatment of Bcr/Abl+ leukemia, especially CML patients in early chronic phase. However, it has become clear that rare clones with mutations that confer resistance to imatinib (e.g., mutations in bcr-abl that prevent imatinib binding) can survive, and this resistance can lead to relapse and limits the effects for patients with advanced disease (1). Because the inhibition of cell proliferation by the blockade of Bcr/Abl with imatinib is not sufficient for eradicating Bcr/Abl+ leukemic clones, a better understanding of the mechanisms by which imatinib kills cells and how this killing can be augmented may lead to improved therapeutic strategies.. Although, our study confirmed that Bcl-2 or Bcl-xL overexpression (7) or RNAi-mediated reduction of Bim (8, 9) inhibits imatinib-induced apoptosis in K562 cells, we found that it is the combination of Bim and Bad that accounts for the killing activity of imatinib. Imatinib caused a marked reduction in ...

OBJECTIVE: Despite the efficacy of the BCR-ABL tyrosine kinase inhibitor imatinib, the development of resistance against imatinib has been observed. The most important mechanisms known to cause resistance are point mutations in the ABL tyrosine kinase and the ATP domain. This study describes the use of denaturing high performance liquid chromatography (dHPLC) as a method to screen for mutations of the ABL gene.METHODS: We used the dHPLC based assay for the screening of ABL point mutations. Forty chronic myeloid leukemia (CML) patients who showed resistance to imatinib were screened in parallel by dHPLC and direct sequencing.RESULTS: Nine of the 40 patients (23%) had mutations. CONCLUSION: dHPLC can be a useful method for pre-screening. Analyzing the mutations and monitoring (high-risk) patients can improve their prognosis and survival rate. dHPLC can potentially become a valuable tool for regular testing of patients in the future ...
Glivec leukaemia drug binding to its target, the enzyme Bcr-Abl tyrosine kinase. This enzyme is produced by a genetic mutation, the swapping of parts of two chromosomes, leading to the formation of the oncogene (cancer-causing gene) Bcr-Abl, which produces a constantly-active version of normal Abl tyrosine kinase. This causes chronic myelogenous leukaemia (CML), a cancer of white blood cells. The drug Glivec (Imatinib) works by binding to the active site of the Bcr-Abl enzyme, producing a change in shape that prevents the enzyme from functioning. This causes the death of cancerous cells expressing the enzyme. Glivec, the first such tyrosine kinase inhibitor to be produced, is marketed by Novartis. - Stock Video Clip K003/2147

With the piperazine ligands, a mixture of species was observed and various solid-state structures were isolated. However, with homopiperazine salan ligands, 1:1 ligand-tometal complexes were observed both in solution and in the solid state. Interestingly, for the homopiperazine complexes the isopropoxide ligands are trans to one another in the solid state, most likely because of the rigid nature of the homopiperazine backbone. All homopiperazine Hf(IV) and Zr(IV) complexes were tested for the ring-opening polymerisation (ROP) of rac-lactide. The ...
Its advisable to have a veterinarian diagnose your cats parasitic infestation before you treat your pet with piperazine. This drug is a powerful one that can easily be missed if you dont have a vets careful attention to help you out. If your cat has been diagnosed with roundworms or some other type of parasite, ask your vet whether piperazine will be a suitable way of helping to deal with the issue.. Piperazine is available in tablet form and can be included with your cats meal or ground up and provided with a treat. The exact dosage that youll give to your cat is somewhat dependent upon his size, age, overall health condition, and the severity of the parasitic infection that hes suffering from. Youll typically provide your pet with a single dose of the drug, though you may need to repeat it in two to three weeks in order to ensure that all worms are flushed from the system.. ...

Preliminary investigations suggest that platelet-derived growth factor (PDGF) might have a role in the development of cervical cancer, therefore it is important to determine whether this growth factor pathway is functional and its targeting with imatinib mesylate leads to growth inhibition of cervical cancer cells. PDGF receptors (PDGFR) and their ligands are frequently expressed in cervical cancer and the majority exhibited a combination of family members co-expression. A number of intronic and exonic variations but no known mutations in the coding sequence of the PDGFRα gene were found in cancer cell lines and primary tumors. Growth assays demonstrated that PDGFBB induces growth stimulation that can be blocked by imatinib and that this tyrosine kinase inhibitor on its own inhibits cell growth. These effects were associated with the phosphorylation status

... (Voranil) was developed by Ciba in the 1960s[1] and is an anorectic drug of the amphetamine class.[2] It is the 2-chloro analogue of the better known appetite suppressant phentermine, and is the 2-chloro positional isomer of chlorphentermine. Clortermine produces very low rates of self-administration in animals similarly to chlorphentermine,[3] and as a result it likely does not act on dopamine. Instead, it may act as a serotonin and/or norepinephrine releasing agent.[citation needed] ...
... is a drug and research chemical used in scientific studies. It acts as a monoamine releasing agent with 20- to 48-fold selectivity for releasing dopamine versus serotonin. It is most efficacious as a releaser of norepinephrine, with an ec50 of 109/41.4/5246nM for DA/NE/5HT, respectively .[1] It has a fast onset of action and a short duration.[1] It also functions as a monoamine oxidase inhibitor (MAOI) with preference for MAO-A.[2] ...
... , also known as (-)-3β-(4-iodophenyl)tropane-2β-pyrrolidine carboxamide and RTI-4229-229, is a potent and long-lasting stimulant drug which was developed in the 1990s as part of a large group of related analogues from the phenyltropane family. With the combination of two potent dopamine transporter (DAT) binding motifs attached to the tropane ring, the p-iodophenyl group at the 3β-position and a pyrrolidine carboxamide at 2β, RTI-229 has extremely high selectivity for the dopamine transporter (2600x and 4600x selective over NET and 5-HTT respectively) and is one of the most DAT-selective compounds in the RTI series.[1][2] ...

... ("3,4-MDPEA" or just "MDPEA"), also known as homopiperonylamine, is a substituted phenethylamine formed by adding a methylenedioxy group to phenethylamine. It is structurally similar to MDA, but without the methyl group at the alpha position. According to Alexander Shulgin in his book PiHKAL, MDPEA appears to be biologically inactive. This is likely because of extensive first-pass metabolism by the enzyme monoamine oxidase. However, if MDPEA were either used in high enough of doses (e.g., 1-2 grams), or in combination with a monoamine oxidase inhibitor (MAOI), it is probable that it would become sufficiently active, though it would likely have a relatively short duration of action. This idea is similar in concept to the use of selective MAOA inhibitors and selective MAOB inhibitors in augmentation of dimethyltryptamine (DMT) and phenethylamine (PEA), respectively. ...

... emerged as a new legal high in the United Kingdom only months after the ban of similar drug mephedrone (which was also a cathinone derivative). Until July 2010 the substance was not controlled by the Misuse of Drugs Act 1971 and was therefore not illegal for someone to possess. The Medicines Act prevented naphyrone from being sold for human consumption, and therefore it was sometimes sold as 'pond cleaner' or as another substance not normally consumed by humans. In response to this emerging trend of new designer drugs, Home Office Minister James Brokenshire said, "action to address the issue of emerging legal highs coming on to the market is a priority for the government."[12][unreliable source?] A study by researchers at Liverpool John Moores University found that only one out of ten products labelled as "NRG-1" actually contained naphyrone when they were subjected to laboratory analysis. Compounds found in products labelled NRG-1 included MDPV, flephedrone, mephedrone, butylone and ...
... (Gevilon) is a stimulant drug. It has been used for the treatment of alcoholism[1] and for increasing motivation in elderly patients,[2] but is now mainly used for the treatment of hyperlipoproteinaemia. [3][4] It is chemically similar to the anticonvulsant gabapentin, with a hydroxyl group replacing the amine. The latter use may be incorrectly assigned, as "Gevilon" has been used as a trade name for gemfibrozil, a well-known drug for dislypidemia. ...
... is a synthetic form of the isolated major active metabolite of venlafaxine, and is categorized as a serotonin-norepinephrine reuptake inhibitor (SNRI). When most normal metabolizers take venlafaxine, approximately 70% of the dose is metabolized into desvenlafaxine, so the effects of the two drugs are expected to be very similar.[5] It works by blocking the "reuptake" transporters for key neurotransmitters affecting mood, thereby leaving more active neurotransmitters in the synapse. The neurotransmitters affected are serotonin (5-hydroxytryptamine) and norepinephrine (noradrenaline). It is approximately 10 times more potent at inhibiting serotonin uptake than norepinephrine uptake.[6]. ...

Difluoromethylenedioxyamphetamine (DiFMDA) is a substituted derivative of 3,4-methylenedioxyamphetamine (MDA), which was developed by Daniel Trachsel and coworkers, along with the corresponding fluorinated derivatives of MDMA, MDEA, BDB and MBDB, with the aim of finding a non-neurotoxic drug able to be used as a less harmful substitute for entactogenic drugs such as MDMA. Since a major route of the normal metabolism of these compounds is scission of the methylenedioxy ring, producing neurotoxic metabolites such as alpha-methyldopamine, it was hoped that the difluoromethylenedioxy bioisostere would show increased metabolic stability and less toxicity.[1][2] These compounds have not yet been tested in animals to verify whether they show similar pharmacological activity to the non-fluorinated parent compounds, although in vitro binding studies show DFMDA to have a SERT affinity in between that of MDA and MDMA.[3] However, there is known to be a lack of bulk tolerance at this position of the ...
The mechanism of action of armodafinil is unknown. Armodafinil (R-(−)-modafinil) has pharmacological properties almost identical to those of modafinil (a mixture of R-(−)- and (S)-(+)-modafinil). The (R)- and (S)-enantiomers have similar pharmacological action in animals. Armodafinil has wake-promoting actions similar to sympathomimetic agents including amphetamine and methylphenidate, although its pharmacologic profile is not identical to that of the sympathomimetic amines. Armodafinil is an indirect dopamine receptor agonist; it binds in vitro to the dopamine transporter (DAT) and inhibits dopamine reuptake. For modafinil, this activity has been associated in vivo with increased extracellular dopamine levels. In genetically engineered mice lacking the dopamine transporter, modafinil lacked wake-promoting activity, suggesting that this activity was DAT-dependent. However, the wake-promoting effects of modafinil, unlike those of amphetamine, were not antagonized by the dopamine receptor ...
... or WF-23 is a cocaine analogue. It is claimed to be several hundred times more potent than cocaine at being a serotonin-norepinephrine-dopamine reuptake inhibitor.[1] As can be seen on pubmed, these acyl substituted phenyltropanes are highly potent MAT inhibitors and also have a very long half-life, spanning perhaps at least a few days.[2] [3] ...

Amphetamines like MDMA, MDEA, MDA, and MBDB, among other relatives (see MDxx), are recreational drugs termed entactogens. They act as serotonin-norepinephrine-dopamine releasing agents (SNDRAs) and also agonize serotonin receptors such as those in the 5-HT2 subfamily. Fenfluramine, chlorphentermine, and aminorex, which are also amphetamines and relatives, were formerly used as appetite suppressants but were discontinued due to concerns of cardiac valvulopathy. This side effect has been attributed to their additional action of potent agonism of the 5-HT2B receptor. The designer drug 4-methylaminorex, which is an SNDRA and 5-HT2B agonist, has been reported to cause this effect as well. Many tryptamines, such as DMT, DET, DPT, DiPT, psilocin, and bufotenin, are SRAs as well as non-selective serotonin receptor agonists.[3] These drugs are serotonergic psychedelics, which is a consequence of their ability to activate the 5-HT2A receptor. αET and αMT, also tryptamines, are SNDRAs and non-selective ...

In the United States, MDPV is a DEA federally scheduled drug. On October 21, 2011, the DEA issued a temporary one-year ban on MDPV, classifying it as a schedule I substance. Schedule I status is reserved for substances with a high potential for abuse, no currently accepted use for treatment in the United States and a lack of accepted safety standards for use under medical supervision.[28] Before the federal ban was announced, MDPV was already banned in Louisiana and Florida.[29] On March 24, 2011, Kentucky passed bill HB 121, which makes MDPV, as well as three other cathinones, controlled substances in the state. It also makes it a Class A misdemeanor to sell the drug, and a Class B misdemeanor to possess it.[30] MDPV is banned in New Jersey under Pamela's Law. The law is named after Pamela Schmidt, a Rutgers University student who was murdered in March 2011 by an alleged user of MDPV.[31] A toxicology report later found no "bath salts" in his system.[32] On May 5, 2011, Tennessee Governor Bill ...
... (CGP-15,210-G) is a selective serotonin reuptake inhibitor (SSRI) which was investigated as an antidepressant in the 1980s but was never marketed.[1][2][3] Ifoxetine selectively blocks the reuptake of serotonin in the brain supposedly without affecting it in the periphery.[3] Supporting this claim, ifoxetine was found to be efficacious in clinical trials and was very well tolerated, producing almost no physical side effects or other complaints of significant concern.[3] ...
The LD50 for methylhexanamine is 39 mg/kg in mice and 72.5 mg/kg in rats, when administered intravenously.[7]:95[16]:110 The FDA has stated that methylhexanamine "is known to narrow the blood vessels and arteries, which can elevate blood pressure and may lead to cardiovascular events ranging from shortness of breath and tightening in the chest to heart attack".[17] Numerous adverse events and at least five deaths have been reported in association with methylhexanamine-containing dietary supplements.[3] A 2012 review by a panel convened by the U.S. Department of Defense to study whether the military should ban methylhexanamine supplements from stores on its bases concluded that: "The existing evidence does not conclusively establish that DMAA-containing substances are causally-associated with adverse medical events. However, a consistent theme among the studies is that DMAA use potentially affects cardiovascular function, just as other sympathomimetic stimulants. Without further rigorous study ...

... is a norepinephrine-dopamine reuptake inhibitor (NDRI) under development by Jazz Pharmaceuticals for the treatment of excessive sleepiness associated with narcolepsy and sleep apnea. It is derived from phenylalanine and its chemical name is (R)-2-amino-3-phenylpropylcarbamate hydrochloride.[1] The drug was discovered by a subsidiary of SK Group, which licensed rights outside of 11 countries in Asia to Aerial Pharma in 2011.[2] Aerial ran two Phase II trials of the drug in narcolepsy[3] before selling the license to solriamfetol to Jazz in 2014; Jazz paid Aerial $125 million up front and will pay Aerial and SK up to $272 million in milestone payments, and will pay double digit royalties to SK.[2][4] Solriamfetol had also been tested in animal models of depression, but as of 2017 that work had not been advanced to clinical trials.[5] During development it has been called SKL-N05, ADX-N05, ARL-N05, and JZP-110.[6] In March 2018 the FDA accepted SK's and Jazz' NDA for use of ...
