Oral irritant properties of piperine and nicotine: psychophysical evidence for asymmetrical desensitization effects. (1/270)

Using a bipolar rating scale, human subjects rated the intensity of irritation sensation evoked by repeated application of piperine (75 p.p.m.) or nicotine (0.12%) to one side of the dorsal surface of the tongue. The intensity of irritation elicited by repeated application of piperine significantly increased, while irritation elicited by repeated nicotine significantly decreased. We additionally tested if nicotine or piperine desensitized the tongue. After either piperine or nicotine was repeatedly applied to one side of the tongue, a 5 or 10 min rest period ensued, followed by re-application of piperine or nicotine to both sides of the tongue. Subjects were asked to choose which side of the tongue gave rise to a stronger irritation in a two-alternative forced choice (2-AFC) paradigm. In addition, they gave separate ratings of the intensity of irritation on the two sides of the tongue. When piperine was applied bilaterally after unilateral pretreatment with piperine and a 10 min rest period, subjects consistently chose the non-pretreated side to yield stronger irritation and assigned significantly higher ratings to that side, indicative of piperine self-desensitization. A similar self-desensitization effect was found when bilateral application of nicotine followed unilateral treatment with nicotine and a 5 min rest period. Unilateral treatment with piperine also reduced nicotine-evoked irritation on the pretreated side (cross-desensitization), but treatment with nicotine did not affect piperine-evoked irritation. This asymmetrical cross-desensitization pattern is similar to that observed between capsaicin and nicotine and constitutes an additional similarity between piperine and capsaicin.  (+info)

Effect of vanilloid drugs on gastrointestinal transit in mice. (3/270)

1. We have studied the effect of capsaicin, piperine and anandamide, drugs which activate vanilloid receptors and capsazepine, a vanilloid receptor antagonist, on upper gastrointestinal motility in mice. 2. Piperine (0.5 - 20 mg kg(-1) i.p.) and anandamide (0.5 - 20 mg kg(-1) i.p.), dose-dependently delayed gastrointestinal motility, while capsaicin (up to 3 mg kg(-1) i.p.) was without effect. Capsazepine (15 mg kg(-1) i.p.) neither per se affected gastrointestinal motility nor did it counteract the inhibitory effect of both piperine (10 mg kg(-1)) and anandamide (10 mg kg(-1)). 3. A per se non effective dose of SR141716A (0.3 mg kg(-1) i.p.), a cannabinoid CB(1) receptor antagonist, counteracted the inhibitory effect of anandamide (10 mg kg(-1)) but not of piperine (10 mg kg(-1)). By contrast, the inhibitory effect of piperine (10 mg kg(-1)) but not of anandamide (10 mg kg(-1)) was strongly attenuated in capsaicin (75 mg kg(-1) in total, s.c.)-treated mice. 4. Pretreatment of mice with N(G)-nitro-L-arginine methyl ester (25 mg kg(-1) i.p.), yohimbine (1 mg kg(-1), i.p.), naloxone (2 mg kg(-1) i.p.), or hexamethonium (1 mg kg(-1) i.p.) did not modify the inhibitory effect of both piperine (10 mg kg(-1)) and anandamide (10 mg kg(-1)). 5. The present study indicates that the vanilloid ligands anandamide and piperine, but not capsaicin, can reduce upper gastrointestinal motility. The effect of piperine involves capsaicin-sensitive neurones, but not vanilloid receptors, while the effect of anandamide involves cannabinoid CB(1), but not vanilloid receptors.  (+info)

Protective action of piperine against experimental gastric ulcer. (4/270)

AIM: To study the effects of piperine (Pip) on several experimental gastric ulcers in rats and mice. METHODS: The gastric mucosa damage was induced by stress, indometacin, HCl, and pyloric ligation in rats or mice. The number of gastric ulcers, the volume and acidity of gastric juices, and pepsin A activity were detected. RESULTS: Pip 25, 50, 100 mg/kg ig protected animals from gastric ulceration in a dose-dependent manner. The inhibitory rates were 16.9%, 36.0%, and 48.3% in stress ulcers; 4.4%, 51.1%, and 64.4% in indometacin ulcers; 19.2%, 41.5%, and 59.6% in HCl ulcers; 4.8%, 11.9%, and 26.2% in pyloric ligation ulcers, respectively; Pip inhibited the volume of gastric juice, gastric acidity, and pepsin A activity. CONCLUSION: Pip has the protective effects against gastric ulceration.  (+info)

Piperine, a major constituent of black pepper, inhibits human P-glycoprotein and CYP3A4. (5/270)

Dietary constituents (e.g., in grapefruit juice; NaCl) and phytochemicals (e.g., St. John's wort) are important agents modifying drug metabolism and transport and thereby contribute to interindividual variability in drug disposition. Most of these drug-food interactions are due to induction or inhibition of P-glycoprotein and/or CYP3A4. Preliminary data indicate that piperine, a major component of black pepper, inhibits drug-metabolizing enzymes in rodents and increases plasma concentrations of several drugs, including P-glycoprotein substrates (phenytoin and rifampin) in humans. However, there are no direct data whether piperine is an inhibitor of human P-glycoprotein and/or CYP3A4. We therefore investigated the influence of piperine on P-glycoprotein-mediated, polarized transport of digoxin and cyclosporine in monolayers of Caco-2 cells. Moreover, by using human liver microsomes we determined the effect of piperine on CYP3A4-mediated formation of the verapamil metabolites D-617 and norverapamil. Piperine inhibited digoxin and cyclosporine A transport in Caco-2 cells with IC(50) values of 15.5 and 74.1 microM, respectively. CYP3A4-catalyzed formation of D-617 and norverapamil was inhibited in a mixed fashion, with K(i) values of 36 +/- 8 (liver 1)/49 +/- 6 (liver 2) and 44 +/- 10 (liver 1)/77 +/- 10 microM (liver 2), respectively. In summary, we showed that piperine inhibits both the drug transporter P-glycoprotein and the major drug-metabolizing enzyme CYP3A4. Because both proteins are expressed in enterocytes and hepatocytes and contribute to a major extent to first-pass elimination of many drugs, our data indicate that dietary piperine could affect plasma concentrations of P-glycoprotein and CYP3A4 substrates in humans, in particular if these drugs are administered orally.  (+info)

Arylnaphthalide lignans from Cleistanthus collinus. (6/270)

Chemical examination of the aerial parts of Cleistanthus collinus afforded the arylanphthalide lignans, cleistanone (1), diphyllin (2), cleistanthins A (3), C (4) and D (5), and 4-O-(3"-O-methyl-beta-D-glucopyranosyl)-diphyllin (6). The first compound is a new member of the rare group of arylnaphthalide lignans containing an alkoxy group on the lactone ring. The structure of the compound was determined from its spectral data, chemical transformations and partial synthesis from diphyllin (2). The new lignan, 1 and its acetyl derivative, 7 were found to exhibit cytotoxicity against MT(2) cell lines.  (+info)

Individual differences in perception of bitterness from capsaicin, piperine and zingerone. (7/270)

It was recently shown that in some subjects capsaicin can evoke bitterness as well as burning and stinging, particularly in the circumvallate (CV) region of the tongue. Because perception of bitterness from capsaicin is characterized by large individual differences, the main goal of the present study was to learn whether people who taste capsaicin as bitter also report bitterness from structurally similar sensory irritants that are known to stimulate capsaicin-sensitive neurons. The irritancy and taste of capsaicin and two of its most commonly studied congeners, piperine and zingerone, were measured in individuals who had been screened for visibility of, and reliable access to, the CV papillae. Approximately half of these individuals reported tasting bitterness from all three irritants when the stimuli were swabbed directly onto the CV papillae. Concentrations that produced similar levels of burning sensation across subjects also produced similar (though lower) levels of bitter taste. These results are consistent with the hypothesis that capsaicin and its congeners stimulate bitterness via a common sensory receptor that is distributed differentially among individuals. Additionally, bitter tasters rated gustatory qualities (but not burning and stinging) slightly but significantly higher than did bitter non-tasters, which suggests that perception of capsaicin bitterness is associated with a higher overall taste responsiveness (but not chemesthetic responsiveness) in the CV region.  (+info)

Piperine enhances the bioavailability of the tea polyphenol (-)-epigallocatechin-3-gallate in mice. (8/270)

(-)-Epigallocatechin-3-gallate (EGCG), from green tea (Camellia sinensis), has demonstrated chemopreventive activity in animal models of carcinogenesis. Previously, we reported the bioavailability of EGCG in rats (1.6%) and mice (26.5%). Here, we report that cotreatment with a second dietary component, piperine (from black pepper), enhanced the bioavailability of EGCG in mice. Intragastric coadministration of 163.8 micromol/kg EGCG and 70.2 micromol/kg piperine to male CF-1 mice increased the plasma C(max) and area under the curve (AUC) by 1.3-fold compared to mice treated with EGCG only. Piperine appeared to increase EGCG bioavailability by inhibiting glucuronidation and gastrointestinal transit. Piperine (100 micromol/L) inhibited EGCG glucuronidation in mouse small intestine (by 40%) but not in hepatic microsomes. Piperine (20 micromol/L) also inhibited production of EGCG-3"-glucuronide in human HT-29 colon adenocarcinoma cells. Small intestinal EGCG levels in CF-1 mice following treatment with EGCG alone had a C(max) = 37.50 +/- 22.50 nmol/g at 60 min that then decreased to 5.14 +/- 1.65 nmol/g at 90 min; however, cotreatment with piperine resulted in a C(max) = 31.60 +/- 15.08 nmol/g at 90 min, and levels were maintained above 20 nmol/g until 180 min. This resulted in a significant increase in the small intestine EGCG AUC (4621.80 +/- 1958.72 vs. 1686.50 +/- 757.07 (nmol/g.min)). EGCG appearance in the colon and the feces of piperine-cotreated mice was slower than in mice treated with EGCG alone. The present study demonstrates the modulation of the EGCG bioavailablity by a second dietary component and illustrates a mechanism for interactions between dietary chemicals.  (+info)

NSCLC cell lines showed different activation of EGFR- and Src-dependent pathways and variable sensitivity to Src inhibitors. A kinase assay demonstrated that all the compounds are able to directly inhibit not only Src, but also EGFR TK variants. However, in cell lysates only saracatinib and bosutinib efficiently reduced EGFR activation, while dasatinib was the more effective agent in inhibiting Src TK. In EGFR-activating mutant, erlotinib sensitive cells, saracatinib and bosutinib showed anti-proliferative effects related to simultaneous EGFR/Src inhibition. In EGFR wt/Ras mutant cells Src inhibition by dasatinib interfered with cell proliferation and signal transduction. Since Src inhibitors had only moderate effects as single agents, both in vitro and in vivo, we tested the combination of saracatinib with EGFR inhibitors (erlotinib or cetuximab) in EGFR-addicted cells, and of dasatanib with MEK inhibitors (selumetinib) in Ras mutant, erlotinib resistant models. These combinations were ...
Endoplasmic reticulum (ER) is the key organelle involved in protein folding and maturation. Emerging studies implicate the role of ER stress in the development of chronic kidney disease. Thus, there is an urgent need for compounds that could ameliorate ER stress and prevent CKD. Piperine and its analogs have been reported to exhibit multiple pharmacological activities; however, their efficacy against ER stress in kidney cells has not been studied yet. Hence, the goal of this study was to synthesize amide-substituted piperine analogs and screen them for pharmacological activity to relieve ER stress using an in vitro model of tunicamycin-induced ER stress using normal rat kidney (NRK-52E) cells. Five amide-substituted piperine analogs were synthesized and their chemical structures were elucidated by pertinent spectroscopic techniques. An in vitro model of ER stress was developed using tunicamycin, and the compounds of interest were screened for their effect on cell viability, and the expression of ...

Endogenous estrogens mediate protective effects in the cardiovascular system in part due to rapid activation of endothelial nitric oxide synthase (eNOS), which involves the classical estrogen receptor (ER) α. Estrogen-dependent increases in NO bioactivity may also be mediated by the G protein-coupled estrogen receptor (GPER/GPR30), although the contribution of GPER to the overall response to estrogen and the mechanisms involved remain unclear. We have investigated GPER-mediated NO signaling in telomerase-immortalized human umbilical vein endothelial (TIVE) cells as well as estrogen-dependent, GPER-mediated relaxation in mouse aortae. Similar to the non-selective ER agonist 17β-estradiol (E2), the GPER-selective agonist G-1 stimulated phosphorylation of eNOS (ser1171) at 100 nM vs. 0.01% DMSO vehicle (53 +/-7 vs. 19+/-4, p=0.035, n=4). Colorimetric detection of nitric oxide demonstrated that Acetylcholine (Ach) (536 +/-18), E2 (425+/- 18) and G-1 (308 +/-18) also increased NO production in ...
G protein-coupled Estrogen Receptor 1 is a member of the GPCR family and is encoded in Humans by the GPER gene. Alternate transcriptional splice variants that encode the same protein have been characterized. It is a member of the rhodopsin-like family and is localized to the endoplasmic reticulum membrane. GPER binds estrogen with high affinity, resulting in intracellular calcium mobilization and synthesis of phosphatidylinositol 3,4,5-trisphosphate in the nucleus.
Methylenedioxypyrovalerone (MDPV) is a stimulant of the cathinone class which acts as a norepinephrine-dopamine reuptake inhibitor (NDRI). It was first developed in the 1960s by a team at Boehringer Ingelheim. MDPV remained an obscure stimulant until around 2004 when it was reportedly sold as a designer drug. Products labeled as bath salts containing MDPV were previously sold as recreational drugs in gas stations and convenience stores in the United States, similar to the marketing for Spice and K2 as incense. The hydrochloride salt exists as a very fine, hygroscopic, crystalline powder that tends to clump to itself, resembling something like powdered sugar. Its color can range from pure white to a yellowish-tan and has a slight odor that strengthens as it colors. Impurities are likely to consist of either pyrrolidine or alpha-dibrominated alkylphenones from either excess pyrrolidine or incomplete amination, respectively, during synthesis. These impurities likely account for its discoloration ...
The present study provides evidence that endogenous GPER regulates vascular activity of prostanoid-dependent endothelial vasoconstriction. Chronic deficiency of the GPER gene has no effect on NO bioactivity but is associated with enhanced VSMC contraction to endothelium-dependent, COX-derived vasoconstrictor prostanoids and to direct TP receptor activation. In addition, histological and immunohistochemical analyses revealed structurally normal arteries in GPER0 mice. By contrast, acute blockade of GPER decreases both basal and stimulated endothelial NO bioactivity and increases EDCF-mediated responses while contractions to a TP receptor agonist remain unchanged. These data identify GPER as a novel, inhibitory regulator of endothelial vasoconstrictor prostanoids and as the first estrogen receptor specifically associated with the regulation of endothelial vasoconstriction.. Acetylcholine induces the release of 2 counteracting endothelial mediators in the mouse aorta: NO-mediated relaxation is ...

Introduction: Prostate cancer treatment with androgen deprivation is typically efficacious for two years prior to the development of castration resistant disease (CRPC). The Src family kinases (SFK) are upregulated with androgen deprivation and have been implicated in the progression to CRPC. Saracatinib is a specific SFK inhibitor that inhibits castration resistant growth and metastases in an animal model using LNCaP cells overexpressing the neuropeptide gastrin-releasing peptide. We test the hypothesis that saracatinib given immediately after androgen deprivation inhibits castration resistant tumor recurrence using a CWR22 xenograft model. Materials and Methods: CWR22 prostate cancer xenografts were injected subcutaneously into nude mice primed with testosterone pellets (21-day release). Twenty-six mice were castrated after adequate tumor development (day 0). Mice in the treatment arm were administered saracatinib from day 7 to day 150. Mice were sacrificed at days 0, 3, 30 and 150. Tumors and ...

A phase Ib multiple ascending dose study of the safety, tolerability, and central nervous system availability of AZD0530 (saracatinib) in Alzheimers disease.
Introduction: Activated Cdc42-associated kinase (ACK1, TNK2) has been reported to be over-expressed in a range of tumor types including prostate and lung cancer, and has been suggested as a potential novel anticancer target. A number of kinase inhibitors currently in clinical development show inhibition of ACK1 biochemical activity in enzyme assays, yet their ability to inhibit ACK1 in vivo is unknown. This study describes the development of a pharmacodynamic model to evaluate ACK1 target coverage in vivo.. Methods: MDA-MB-231 cells were engineered to over-express ACK1 under the control of a doxycycline-inducible promoter (MDA-MB-231-ACK1). MDA-MB-231-ACK1 cells were grown as subcutaneous xenografts in MF-1 nude mice and ACK1 expression induced by dosing doxycycline by oral gavage. Saracatinib/AZD-0530 (100mg/kg qd) or ASP-3026 (50mg/kg bid) were dosed for four consecutive days to reach steady state exposures at approximately MTD. Pharmacodynamic inhibition of ACK1 autophosphorylation was ...

The endocannabinoid (eCB) system regulates mood, emotion, and stress coping, and dysregulation of the eCB system is critically involved in pathophysiology of depression. The eCB ligand 2-arachidonoylglycerol (2-AG) is inactivated by monoacylglycerol lipase (MAGL). Using chronic unpredictable mild stress (CUS) as a mouse model of depression, we examined how 2-AG signaling in the hippocampus was altered in depressive-like states and how this alteration contributed to depressive-like behavior. We report that CUS led to impairment of depolarization-induced suppression of inhibition (DSI) in mouse hippocampal CA1 pyramidal neurons, and this deficiency in 2-AG-mediated retrograde synaptic depression was rescued by MAGL inhibitor JZL184. CUS induced depressive-like behaviors and decreased mammalian target of rapamycin (mTOR) activation in the hippocampus, and these biochemical and behavioral abnormalities were ameliorated by chronic JZL184 treatments. The effects of JZL184 were mediated by cannabinoid ...
Effects of lignan compounds (sesamol, sesamin, and sesamolin) extracted from roasted sesame oil on the autoxidation at 60 for 7 days and thermal oxidation at 180 for 10 hr of sunflower oil were studied by determining conjugated dienoic acid (CDA) contents, p-anisidine values (PAV), and fatty acid composition. Contents of lignan compounds during the oxidations were also monitored. a-Tocopherol was used as a reference antioxidant. Addition of lignan compounds decreased CDA contents and PAY of the oils during oxidation at 60 or heating at 180 , which indicated that sesame oil lignans lowered the autoxidation and thermal oxidation of sunflower oil. Sesamol was the most effective in decreasing CDA formation and hydroperoxide decomposition in the auto a- and thermo-oxidation of oil, and its antioxidant activity was significantly higher than that of a-tocopherol. Sesamol, sesamin, and sesamolin added to sunflower oil were degraded during the oxidations of oils, with the fastest degradation of sesamol. ...
2-Arachidonoylglycerol plays a major role in endocannabinoid signaling, and is tightly regulated by the monoacylglycerol lipase (MAGL). Here we report the crystal structure of human MAGL. The protein crystallizes as a dimer, and despite structural homologies to haloperoxidases and esterases, it distinguishes itself by a wide and hydrophobic access to the catalytic site. An apolar helix covering the active site also gives structural insight into the amphitropic character of MAGL, and likely explains how MAGL interacts with membranes to recruit its substrate. Docking of 2-arachidonoylglycerol highlights a hydrophobic and a hydrophilic cavity that accommodate the lipid into the catalytic site. Moreover, we identified Cys201 as the crucial residue in MAGL inhibition by N-arachidonylmaleimide, a sulfhydryl-reactive compound. Beside the advance in the knowledge of endocannabinoids degradation routes, the structure of MAGL paves the way for future medicinal chemistry works aimed at the design of new ...

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease of the motor neuron system with limited therapeutic options. While an increasing number of ALS patients can be linked to a small number of autosomal-dominantly inherited cases, most cases are termed sporadic. Both forms are clinically and histopathologically indistinguishable, raising the prospect that they share key pathogenic steps, including potential therapeutic intervention points. The endocannabinoid system is emerging as a versatile, druggable therapeutic target in the CNS and its dysregulation is an early hallmark of neurodegeneration. Whether this is a defense mechanism or part of the pathogenesis remains to be determined. The neuroprotective and anti-inflammatory endocannabinoid 2-arachidonoylglycerol (2-AG), which is degraded by monoacylglycerol lipase (MAGL), accumulates in the spinal cords of transgenic models of ALS. We tested the hypothesis that this 2-AG increase is a protective response in the low-copy ...

Deficits in social interaction (SI) are a core symptom of autism spectrum disorders (ASDs); however, treatments for social deficits are notably lacking. Elucidating brain circuits and neuromodulatory signaling systems that regulate sociability could facilitate a deeper understanding of ASD pathophysiology and reveal novel treatments for ASDs. Here we found that in vivo optogenetic activation of the basolateral amygdala-nucleus accumbens (BLA-NAc) glutamatergic circuit reduced SI and increased social avoidance in mice. Furthermore, we found that 2-arachidonoylglycerol (2-AG) endocannabinoid signaling reduced BLA-NAc glutamatergic activity and that pharmacological 2-AG augmentation via administration of JZL184, a monoacylglycerol lipase inhibitor, blocked SI deficits associated with in vivo BLA-NAc stimulation. Additionally, optogenetic inhibition of the BLA-NAc circuit markedly increased SI in the Shank3B-/- mouse, an ASD model with substantial SI impairment, without affecting SI in WT mice. ...
In an aging society, it can be foreseen that the incidence of diseases associated with undesired bone loss, such as metastatic bone disease, rheumatoid arthritis, osteoporosis, and periodontitis, will increase considerably. Thus, drugs specifically targeting osteoclasts and their activity are desirable, possibly as supplementary agents to existing therapies. Orally applicable Src inhibitors could be advantageous compared with the widely used bisphosphonates because the latter can cause complications in the upper gastrointestinal tract (15) or can lead to osteonecrosis of the jaw (16). Indeed, the Src inhibitor CGP76030 was shown to reduce the number of osteoclasts in rat tibiae more efficiently than the bisphosphonate alendronate (18). Little is known, however, of the effect of Src inhibitors on human osteoclasts. Here, we describe the effect of Src inhibitor AZD0530 on osteoclast formation and activity in the different models used (osteoblast/PBMC cocultures, PBMCs cultured at high density ...

3,4-Methylenedioxy-α-pyrrolidinobutyrophenone (MDPBP) is a stimulant of the cathinone class developed in the 1960s, which has been reported as a novel designer drug. MDPBP is sometimes sold under the name "NRG-1" as a mixture with other cathinone derivatives, including flephedrone, pentylone, MαPPP and its higher homologue MDPV. As with other cathinones, MDPBP has been shown to have reinforcing effects in rats. The main metabolic steps are thought to be demethylenation followed by methylation of one hydroxy group, aromatic and side chain hydroxylation, oxidation of the pyrrolidine ring to the corresponding lactam as well as ring opening to the corresponding carboxylic acid. CYP2C19 and CYP2D6 have been identified as the isoenzymes mainly responsible for demethylenation. As of October 2015 MDPBP is a controlled substance in Poland and China. α-Pyrrolidinobutiophenone (α-PBP) Butylone 3,4-Methylenedioxy-α-pyrrolidinopropiophenone (MDPPP) Methylenedioxypyrovalerone (MDPV) Herbert, Koeppe; ...
A 24-year-old Batavia resident who allegedly gave bath salts to a minor did so, she reportedly told a DSS caseworker, because she thought the chemical was legal, therefore it was OK. Ashley R. Keene, of 244 Liberty St., Batavia, is charged with endangering the welfare of a child. Her alleged admission to giving bath salts to a 14-year-old girl are contained in court documents on file with Batavia City Court. According to a DSS worker who made a statement in support of Keenes arrest, Keene said she didnt understand on May 28, Memorial Day, that giving a child bath salts was illegal. Keene is the girlfriend of Jason D. Lang, 28, of 244 Liberty St., Batavia, who is currently being held in Genesee County Jail. He is accused of falsely reporting an incident for allegedly calling 9-1-1 to report gunshots at a local hotel July 2. In court documents, a Batavia PD officer reports that in a jailhouse interview, Lang denied participating in giving the girl bath salts and says he warned Keene against it, but
The mitochondrial pool of Hsp90 and its mitochondrial paralog, TRAP1, suppresses cell death and reprograms energy metabolism in cancer cells; therefore, Hsp90 and TRAP1 have been suggested as target proteins for anticancer drug development. Here, we report that the actual target protein in cancer cell mitochondria is TRAP1, not Hsp90, and current Hsp90 inhibitors cannot effectively inactivate TRAP1 due to insufficient accumulation in the mitochondria. To develop mitochondrial TRAP1 inhibitors, we determined the crystal structures of human TRAP1 complexed with Hsp90 inhibitors. The isopropyl amine of the Hsp90 inhibitor PU-H71 was replaced with the mitochondria-targeting moiety triphenylphosphonium to produce SMTIN-P01. SMTIN-P01 showed a different mode of action from the non-targeted PU-H71, as well as much improved cytotoxicity to cancer cells. In addition, we determined the structure of a TRAP1-adenylyl-imidodiphosphate (AMP-PNP) complex. Based on comparative analysis of TRAP1 structures, we ...

Black pepper is native to India is the worlds most traded spice, found beside a large amount of dinner tables next to the salt. Black peppers characteristic flavor comes from the chemical piperine. Black pepper is used as a universal absorption enhancer by modern herbalists. Black pepper can be ground over most meals, taken in capsules or sprinkled in tea to achieve the distinct pepper taste and to improve absorption of nutrients, vitamins, and other compounds. Enhances the effects & anti-oxidant capability of Turmeric, Green tea, and most other herbs & vegetables. The active chemical in black pepper, piperine can dramatically increase absorption of selenium, vitamin B, beta-carotene, curcumin (turmeric) and more by up to 2000%! Piperine also enhances the thermogenesis of lipid and accelerates energy metabolism in the body while increasing the serotonin and beta-endorphin production in the brain.

The patients were predominantly male (64%, 52/81) with a median age of 34 years. 60 were admitted for signs of acute intoxication while 21 suffered from complications of cathinone use. 70% of acutely intoxicated patients had an increased creatinine phosphokinase. Only a minority of patients presented with a sympathomimetic toxidrome. Three patients had infectious complications, 10 prolonged psychosis, 6 rhabdomyolyses and/or kidney failure, and two patients died. Based on presentations, cathinone use has increased with the first cases seen in 2010. Opiates/opioids are the main co-ingested drugs of abuse. The pattern of cathinone use shifted from methylone in 2010/2011 to 3,4-methylenedioxypyrovalerone (MDPV) and 3-methylmethcathinone (3-MMC) in 2014/2015. We conclude that in our setting typical cathinone users are males in their thirties. They are seldom drug naïve and regularly co-ingest illicit drugs. Preventive measures have to be tailored to these difficult to reach patients. Present ...

The present study explored their mode of action in gastrointestinal disorders, such as diarrhea and colic. Piperine at the dose of 10 mg/kg provided complete protection from castor oil-induced diarrhea in mice, similar to that of loperamide. In isolated rabbit jejunum preparations, piperine exhibited concentration-dependent inhibition of spontaneous contractions with an EC50 value of 149.1 μM (89.26-249.20, 95% CI). When used to treat high K+ (80 mM)-induced sustained contractions, piperine inhibited such contractions with an EC50 value of 80.86 μM (56.10-116.50, 95% CI), which suggested a calcium channel blocking (CCB) effect. The CCB effect was further confirmed when pretreatment of the tissues with piperine (10-100 μM) caused a rightward shift in the Ca++ concentration-response curves (CRCs) in Ca++-free medium, similar to that caused

Black pepper is an economically important crop, but foot rot caused by P. capsici has influenced its industry. The molecular mechanisms of disease resistance in black pepper remained unclear. Transcriptome sequencing, a significant tool, is being increasingly applied in the identification of the genes governing characteristic traits. Currently, NGS is being broadly employed for the qualitative and quantitative analysis of transcriptomes. Sheila et al. generated 71 million reads from stem-root tissue using the SOLiD platform (short reads) in black pepper [4]. The present study used transcriptome sequence analysis to obtain 147.44 Mb reads for P. nigrum and 147.49 Mb reads for P. flaviflorum, which corresponded to approximately 13.27G of raw sequence data, respectively. Subsequently, trinity was utilized to assembly raw reads for predicting unique genes. Among all the databases, including KEGG, NT, GO, Swiss-Prot and NR, annotated unigenes accounted for 68.46 % of the total amount of unigenes. ...
The popularity of new psychoactive substances (NPS) has grown in recent years, with certain NPS commonly and preferentially consumed even following the introduction of preventative legislation. With the objective to improve the knowledge on the use of NPS, a rapid and very sensitive method was developed for the determination of ten priority NPS (N-ethylcathinone, methylenedioxypyrovalerone (MDPV), methylone, butylone, methedrone, mephedrone, naphyrone, 25-C-NBOMe, 25-I-NBOMe and 25-B-NBOMe) in influent wastewater. Sample clean-up and pre-concentration was made by off-line solid phase extraction (SPE) with Oasis MCX cartridges. Isotopically labelled internal standards were used to correct for matrix effects and potential SPE losses. Following chromatographic separation on a C18 column within 6 min, the compounds were measured by tandem mass spectrometry in positive ionization mode. The method was optimised and validated for all compounds. Limits of quantification were evaluated by spiking ...
