TY - JOUR. T1 - Physical properties of aqueous blends of sodium glycinate (SG) and piperazine (PZ) as a solvent for CO2 capture. AU - Shaikh, M. S.. AU - Shariff, A. M.. AU - Bustam, M. A.. AU - Murshid, Ghulam. PY - 2013/3/14. Y1 - 2013/3/14. N2 - The physical properties including the density, viscosity, and refractive index of aqueous blends of sodium glycinate (SG) and piperazine (PZ) as a solvent for CO2 absorption were measured under the wide temperature range (298.15 to 343.15) K. Different concentrations (mole fraction) of sodium glycinate and piperazine (SG + PZ) blends were (0.0348/0.0089, 0.0263/0.0177, 0.0177/0.0263, and 0.0089/0.0348), respectively. From the observations, it was found that the densities of the aqueous blends decrease when the piperazine concentration in the blend increases. It was noticed that the viscosity of the blend decreases initially by increasing the concentration of piperazine from 0.0089 to 0.0177 mole fraction; however, on further increasing the piperazine ...

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. Primesep 200 column is more suitable for analysis since piperazine interacts strongly with stationary phase and since Primesep 200 columns are weaker columns. Methods can be used for analysis of piperazine and other basic hydrophilic compounds in reaction mixtures, formulations, biofluids, waste waters, etc. This Method is compatible with ELSD, CAD and LC/MS. ...

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. Thats why we included it in the results, but as unverified…. note: sometimes we get the complaint that the test doesnt work. NOT CORRECT!

Treatment with the specific tyrosine kinase inhibitor imatinib mesylate has achieved excellent results in CML, at all stages of the disease. However, limitations to the successful use of imatinib mesylate as a single agent include the problem of resistance, seen chiefly in patients with advanced-phase disease. This review summarizes the clinical results to date with imatinib mesylate and briefly discusses the problem of resistance before describing potential strategies, including the use ...
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

RAD51 is a key protein in the homologous recombination (HR) pathway of DNA double-strand break repair, and HR represents a novel target for cancer therapy. Because imatinib (Gleevec) has been reported to reduce RAD51 protein levels, we tested the clonogenic survival for RT112, H1299, PANC1, and PC3 tumor cell lines of varying p53 status and normal GM05757 normal fibroblasts after exposure to single agent imatinib (0-20 micromol/L; 0-72 hours). We also combined imatinib with DNA damaging agents that are toxic to RAD51-deficient cells, including ionizing radiation, gemcitabine, and mitomycin C. We observed decreased nuclear expression and chromatin binding of RAD51 protein following imatinib treatment. Imatinib also resulted in decreased error-free HR as determined by a flow cytometry-based integrated direct repeat-green fusion protein reporter system; this correlated to reduced RAD51 expression. Clonogenic survival experiments revealed increased cell kill for imatinib-treated cells in combination with

TY - JOUR. T1 - Homopiperazine and piperazine complexes of Zr(IV) and Hf(IV) and their application to the ring-opening polymerisation of lactide. AU - Hancock, Stuart L. AU - Mahon, Mary F. AU - Kociok-Kohn, Gabriele. AU - Jones, Matthew D. PY - 2011/10. Y1 - 2011/10. N2 - In this paper we describe the preparation and characterisation, by single-crystal X-ray diffraction, of twelve ZrIV/HfIV complexes based on piperazine or homopiperazine salan ligands. 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.. ...

Despite significant achievements in the treatment of cervical cancer, it is still a deadly disease; hence newer therapeutical modalities are needed. 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
