Identification of selective mechanism-based inactivators of cytochromes P-450 2B4 and 2B5, and determination of the molecular basis for differential susceptibility. (1/428)

Rabbit cytochromes P-450 (P-450) 2B4 and 2B5 differ by only 12 amino acid residues yet they exhibit unique steroid hydroxylation profiles. Previous studies have led to the identification of active site residues that are determinants of these specificities. In this study, mechanism-based inactivators were identified that discriminate between the closely related 2B4 and 2B5 enzymes. A previously characterized inhibitor, 2-ethynylnaphthalene (2EN), was found to be selective for 2B4 inactivation. As inhibitor metabolism and the partition ratio affect susceptibility, molecular dynamics simulations were performed to assess the stability of the productive binding orientation of 2EN within 2B4 and 2B5 three-dimensional models. Although 2EN was stable within the 2B4 model, it exhibited substantial movement away from the heme moiety in the 2B5 model. However, heterologously expressed 2B5 was found to catalyze the oxidation of 2EN to the stable product 2-naphthylacetic acid. Thus, the increased mobility of 2EN may result in reduced susceptibility of 2B5 by increasing the probability that the reactive ketene intermediate hydrolyzes with water instead of reacting with active site residues. Another compound, 1-adamantyl propargyl ether (1APE), selectively inactivated 2B5. The structural basis for 2EN and 1APE susceptibility was assessed using active site mutants. Interconversion of 2EN susceptibility was observed for 2B4 or 2B5 mutants containing a single alteration at residue 363. Single substitutions in 2B4 also conferred susceptibility to 1APE; however, multiple alterations were required to reduce the susceptibility of 2B5. These alterations may influence inhibitor susceptibility by affecting the stability of the productive binding orientation.  (+info)

Guest exchange in an encapsulation complex: a supramolecular substitution reaction. (2/428)

Encapsulation complexes are reversibly formed assemblies in which small molecule guests are completely surrounded by large molecule hosts. The assemblies are held together by weak intermolecular forces and are dynamic: they form and dissipate on time scales ranging from milliseconds to days-long enough for many interactions, even reactions, to take place within them. Little information is available on the exchange process, how guests get in and out of these complexes. Here we report that these events can be slow enough for conventional kinetic studies, and reactive intermediates can be detected. Guest exchange has much in common with familiar chemical substitution reactions, but differs in some respects: no covalent bonds are made or broken, the substrate is an assembly rather than a single molecule, and at least four molecules are involved in multiple rate-determining steps.  (+info)

Eukaliuric diuresis and natriuresis in response to the KATP channel blocker U37883A: micropuncture studies on the tubular site of action. (3/428)

1. Systemic application of U37883A, a blocker of ATP sensitive potassium (KATP) channels, elicits diuresis and natriuresis without significantly altering urinary potassium excretion. 2. To elucidate tubular sites of action upstream to the distal nephron, micropuncture experiments were performed in nephrons with superficial glomeruli of anaesthetized Munich-Wistar-Fromter rats during systemic application of U37883A (1, 5 or 15 mg kg-1 i.v.). 3. The observed eukaliuric diuresis and natriuresis in response to U37883A at 15 mg kg-1 was accompanied by an increase in early distal tubular flow rate (VED) from 10 - 18 nl min(-1) reflecting a reduction in fractional reabsorption of fluid up to this site (FR-fluid) of 13%. The latter proposed an effect on water-permeable segments such as the proximal tubule which could fully account for the observed reduction in fractional reabsorption of Na+ up to the early distal tubule (FR-Na+) of 8% and the increase in early distal tubular Na+ concentration ([Na+]ED) from 35 - 51 mM whereas [K+]ED was left unaltered. 4. In comparison, furosemide (3 mg kg-1 i.v.), which acts in the water-impermeable thick ascending limb, elicited diuresis, natriuresis and kaliuresis which were associated with a fall in FR-Na+ of 10% with no change in FR-fluid, and a rise in [Na+]ED from 42 - 117 mM and [K+]ED from 1.2 - 5.7 mM with no change in VED. 5. Direct late proximal tubular fluid collections confirmed a significant inhibition of fluid reabsorption in proximal convoluted tubule in response to systemic application of U37883A. 6. These findings suggest that the diuretic and natriuretic effect upstream to the distal tubule in response to systemic application of U37883A involves actions on water-permeable segments such as the proximal convoluted tubule.  (+info)

Analysis of vasoconstrictor responses to histamine in the hindlimb vascular bed of the rabbit. (4/428)

Hemodynamic responses to histamine were investigated in the anesthetized rabbit. Intravenous injections of histamine induced dose-dependent decreases in systemic arterial pressure that were blocked by the H(1)-receptor antagonist pyrilamine but not the H(2) antagonist cimetidine. Injections of histamine and the H(1) agonist 6-[2-(4-imidazolyl)ethylamine]-N-(4-trifuormethylphenyl)-heptan ecardo xamide dimaleate (HTMT) into the hindlimb perfusion circuit increased hindlimb perfusion pressure, whereas the H(2) agonist dimaprit decreased perfusion pressure and the H(3)-receptor agonist R-(-)-alpha-methylhistamine did not alter perfusion pressure. Pyrilamine reduced hindlimb vasoconstrictor responses to histamine and HTMT but did not alter vasodilator responses to dimaprit. Cimetidine reduced the response to dimaprit but did not alter vasoconstrictor responses to histamine or HTMT. The H(3)-receptor antagonist thioperamide was without effect on responses to the histamine agonists. These data suggest the presence of H(1) and H(2) receptors and that histamine for the most part acts by stimulating H(1) receptors to produce vasoconstriction in the hindlimb vascular bed of the rabbit. Responses to histamine, HTMT, and norepinephrine were significantly enhanced by a nitric oxide synthase inhibitor at a time when vasodilator responses to dimaprit were unaltered and responses to acetylcholine were significantly reduced. Responses to histamine and the H(1) and H(2) agonists were not affected by the cyclooxygenase inhibitor meclofenamate or by ATP-sensitive K(+) channel, alpha-adrenergic, or angiotensin AT(1) receptor antagonists. The present data suggest that H(1) receptors mediate both systemic vasodepressor and hindlimb vasoconstrictor responses to histamine.  (+info)

Block of human aorta Kir6.1 by the vascular KATP channel inhibitor U37883A. (5/428)

1. A human aorta cDNA library was screened at low stringency with a rat pancreatic Kir6.1 cDNA probe and a homologue of Kir6.1 (hKir6.1) was isolated and sequenced. 2. Metabolic poisoning of Xenopus laevis oocytes with sodium azide and application of the K+ channel opener drug diazoxide induced K+ channel currents in oocytes co-injected with cRNA for hKir6.1 and hamster sulphonylurea receptor (SUR1), but not in oocytes injected with water or cRNA for hKir6.1 or SUR1 alone. 3. K+ channel currents due to hKir6.1+SUR1 or mouse Kir6.2+SUR1 were strongly inhibited by 1 microM glibenclamide. K+-current carried by hKir6.1+SUR1 was inhibited by the putative vascular-selective KATP channel inhibitor U37883A (IC50 32 microM) whereas current carried by Kir6.2+SUR1 or Shaker K+ channels was unaffected. 4. The data support the hypothesis that hKir6.1 is a component of the vascular KATP channel, although the lower sensitivity of hKir6.1+SUR1 to U37883A compared with native vascular tissues suggests the need for another factor or subunit. Furthermore, the data suggest that pharmacology of KATP channels can be determined by the pore-forming subunit as well as the sulphonylurea receptor and point to a molecular basis for the pharmacological distinction between vascular and pancreatic/cardiac KATP channels.  (+info)

Inhibition of vascular K(ATP) channels by U-37883A: a comparison with cardiac and skeletal muscle. (6/428)

1 The aim of this study was to investigate the selectivity of the ATP-sensitive potassium (K(ATP)) channel inhibitor U-37883A (4-morpholinecarboximidine-N-1-adamantyl-N'-1-cyclohexyl). Membrane currents through K(ATP) channels were recorded in single muscle cells enzymatically isolated from rat mesenteric artery, cardiac ventricle and skeletal muscle (flexor digitorum brevis). K(ATP) currents were induced either by cell dialysis with 0.1 mM ATP and 0.1 mM ADP, or by application of synthetic potassium channel openers (levcromakalim or pinacidil). 2 U-37883A inhibited K(ATP) currents in smooth muscle cells from rat mesenteric artery. Half inhibition of 10 microM levcromakalim-induced currents occurred at a concentration of 3.5 microM. 3 Relaxations of rat mesenteric vessels caused by levcromakalim were reversed by U-37883A. 1 microM levcromakalim-induced relaxations were inhibited at a similar concentration of U-37883A (half inhibition, 1.1 microM) to levcromakalim-induced KATP currents. 4 K(ATP) currents activated by 100 microM pinacidil were also studied in single myocytes from rat mesenteric artery, skeletal muscle and cardiac ventricle. 10 microM U-37883A substantially inhibited K(ATP) currents in vascular cells, but had little effect in skeletal or cardiac myocytes. Higher concentrations of U-37883A (100 microM) caused a modest decrease in K(ATP) currents in skeletal and cardiac muscle. The sulphonylurea K(ATP) channel antagonist glibenclamide (10 microM) abolished currents in all muscle types. 5 The effect of U-37883A on vascular inward rectifier (KIR) and voltage-dependent potassium (KV) currents was also examined. While 10 microM U-37883A had little effect on these currents, some inhibition was apparent at higher concentrations (100 microM) of the compound. 6 We conclude that U-37883A inhibits K(ATP) channels in arterial smooth muscle more effectively than in cardiac and skeletal muscle. Furthermore, this compound is selective for K(ATP) channels over KV and KIR channels in smooth muscle cells.  (+info)

Early increases in renal kallikrein secretion on administration of potassium or ATP-sensitive potassium channel blockers in rats. (7/428)

1 This study aimed to examine whether administration of potassium or ATP-sensitive potassium channel (KATP channel) blockers caused early increases in renal kallikrein (KK) secretion. To clarify this mechanism, the effect on renal KK secretion of a KATP channel blocker was compared with the effect resulting from use of an osmotic diuretic or volume load. Furthermore, the effect on potassium-induced increases in renal KK secretion by an additional treatment using a KATP channel blocker was examined. Lastly, the effect of a KATP channel blocker on renal KK secretion was also examined in superfused slices of kidney cortex. 2 Intravenous infusion of potassium augmented renal KK secretion within 30 min while urine volume increased gradually in both the potassium loading and control groups. 3 Administration of the KATP channel blocker, 4-morpholinecarboximidine-N-1-adamantyl-N'-cyclohexylhydr ochloride (PNU-37883A) or glibenclamide, caused a dose-dependent increase in renal KK secretion. 4 The concentration of KK in urine was higher in the PNU-37883A group as compared to the osmotic-diuretic or volume-load group. 5 PNU-37883A had no additive effect on the potassium-induced increase in renal KK secretion. 6 Renal KK secretion increased in slices of kidney cortex incubated with PNU-37883A within 10 min of superfusion. 7 In conclusion, administration of both potassium and KATP channel blockers induced early increases in renal KK secretion in the absence of the washout phenomenon. Potassium loading may have increased renal KK secretion through the same mechanism as the KATP channel blocker.  (+info)

Effects of the bcr/abl kinase inhibitors AG957 and NSC 680410 on chronic myelogenous leukemia cells in vitro. (8/428)

The tyrphostin AG957 (NSC 654705) inhibits p210bcr/abl, the transforming kinase responsible for most cases of chronic myelogenous leukemia (CML). The present studies were performed to determine the fate of AG957-treated cells and assess the selectivity of AG957 for CML myeloid progenitors. When K562 cells (derived from a patient with blast crisis CML) were treated with AG957, dose- and time-dependent p210bc/abl down-regulation was followed by mitochondrial release of cytochrome c, activation of caspase-9 and caspase-3, and apoptotic morphological changes. These apoptotic changes were inhibited by transfection with cDNA encoding dominant negative caspase-9 but not dominant-negative FADD or blocking anti-Fas antibodies. In additional experiments, a 24-h AG957 exposure caused dose-dependent inhibition of K562 colony formation in soft agar. To extend these studies to clinical samples of CML, peripheral blood mononuclear cells from 10 chronic phase CML patients and normal controls were assayed for the growth of hematopoietic colonies in vitro in the presence of increasing concentrations of AG957. These assays demonstrated selectivity of AG957 for CML progenitors, with median IC50s (CML versus normal) of 7.3 versus >20 microM AG957 in granulocyte colony-forming cells (P < 0.001), 5.3 versus >20 microM in granulocyte/macrophage colony-forming cells (P < 0.05), and 15.5 versus > 20 microM in erythroid colony-forming cells (P > 0.05). The adamantyl ester of AG957 (NSC 680410) down-regulated p210bcr/abl in K562 cells and inhibited granulocyte colony formation in CML specimens at lower concentrations without enhanced toxicity in normal progenitors. These observations not only demonstrate that AG957-induced p210bcr/abl down-regulation is followed by activation of the cytochrome c/Apaf-1/caspase-9 pathway but also indicate that this class of kinase inhibitor exhibits selectivity worthy of further evaluation.  (+info)

Adamantane - WikipediaAdamantane - Wikipedia
All the above methods yield adamantane as a polycrystalline powder. Using this powder, single crystals can be grown from the melt, solution, or vapor phase (e.g. with the Bridgman-Stockbarger technique). Melt growth results in the worst crystalline quality with a mosaic spread in the X-ray reflection of about 1°. The best crystals are obtained from the liquid phase, but the growth is impracticably slow - several months for a 5-10 mm crystal. Growth from the vapor phase is a reasonable compromise in terms of speed and quality.[2] Adamantane is sublimed in a quartz tube placed in a furnace, which is equipped with several heaters maintaining a certain temperature gradient (about 10 °C/cm for adamantane) along the tube. Crystallization starts at one end of the tube, which is kept near the freezing point of adamantane. Slow cooling of the tube, while maintaining the temperature gradient, gradually shifts the melting zone (rate ~2 mm/hour) producing a single-crystal boule.[16]. ...

The proton-channel activity is inhibited by amine-containing adamantyl drugs amantadine and rimantadine, which have been shown to bind specifically to the pore of M2TM near Ser31. However, whether the polar amine points to the N- or C-terminus of the channel has not yet been determined. Elucidating the polar group direction will shed light on the mechanism by which drug binding inhibits this proton channel and will facilitate rational design of new inhibitors. In this study, we determine the polar amine direction ...

Diamondoid - WikipediaDiamondoid - Wikipedia
In chemistry, diamondoids are variants of the carbon cage molecule known as adamantane (C10H16), the smallest unit cage structure of the diamond crystal lattice. Diamondoids also known as nanodiamonds or condensed adamantanes may include one or more cages (adamantane, diamantane, triamantane, and higher polymantanes) as well as numerous isomeric and structural variants of adamantanes and polymantanes. These diamondoids occur naturally in petroleum deposits and have been extracted and purified into large pure crystals of polymantane molecules having more than a dozen adamantane cages per molecule. These species are of interest as molecular approximations of the diamond cubic framework, terminated with C−H bonds. Cyclohexamantane may be thought of as a nanometer-sized diamond of approximately 6978560000000000000♠5.6×10−22 grams. Examples include: Adamantane (C10H16) Iceane (C12H18) BC-8 (C14H20) Diamantane (C14H20) also diadamantane, two face-fused cages Triamantane (C18H24), also ...

Testing of 2009 influenza A (H1N1), influenza A (H3N2), and influenza B virus isolates for resistance to neuraminidase inhibitors (oseltamivir and zanamivir) is performed at CDC using a functional assay. Additional 2009 influenza A (H1N1) clinical samples are tested for a single mutation in the neuraminidase of the virus known to confer oseltamivir resistance (H275Y). The data summarized below combine the results of both testing methods. These samples are routinely obtained for surveillance purposes rather than for diagnostic testing of patients suspected to be infected with antiviral resistant virus.. High levels of resistance to the adamantanes (amantadine and rimantadine) persist among 2009 influenza A (H1N1) and A (H3N2) viruses (the adamantanes are not effective against influenza B viruses). As a result of the sustained high levels of resistance, data from adamantane resistance testing are not presented in the table below. ...

Seventy-two patients were enrolled (vildagliptin, n = 30; SU, n = 41; no treatment, n = 1), of whom 23 (76.7%) and 36 (87.8%), respectively, completed the study. With vildagliptin, there were no HEs or severe HEs, compared with 34 HEs (15 patients, 41.7%) and one severe (grade 2) HE with SU. The mean between-group difference in the proportion who experienced at least one HE was -41.7% (95%CI -57.8%, -25.6%), p = 0.0002. Vildagliptin lowered mean HbA(1c) from 7.6% (SD 0.9%) at baseline to 7.2% (SD 0.7%) post-Ramadan, whereas SU had no effect (7.2% [SD 0.6%] vs 7.3% [SD 0.7%]; mean between-group difference -0.5% [95% CI -0.9%, -0.1%], p = 0.0262). The mean number of missed doses was markedly lower with vildagliptin (0.2 [SD 0.8] vs 7.6 [SD 14.9]; mean between-group difference -7.4 [95% CI -13.7, -1.20] doses; p = 0.0204).

Nanotechnology Now - Press Release: Application of AdamantaneNanotechnology Now - Press Release: Application of Adamantane
The general molecular formula of homologous diamondoid is C4n+6H4n+12. Diamondoids have one or more cages and are called diamantane, triamantane, and polymantanes. There are numerous structural isomers as well. Aadamantane itself is the simplest diamondoid. Some examples are; iceane (C12H18), diadamantane (C14H20), triadamantane (C18H24), isotetramantane (C22H28), cyclohexamantane (C26H30), superadamantane (C35H36). Natural diamondoids are extracted and purified from petroleum deposits. Diamondoids are being investigated in the new field of nanotechnoloy ...

Saxagliptin - WikipediaSaxagliptin - Wikipedia
Saxagliptin, sold under the brand name Onglyza, is an oral hypoglycemic (anti-diabetic drug) of the dipeptidyl peptidase-4 (DPP-4) inhibitor class. Early development was solely by Bristol-Myers Squibb; in 2007 AstraZeneca joined with Bristol-Myers Squibb to co-develop the final compound and collaborate on the marketing of the drug. In April 2016, the U.S. FDA added a warning about increased risk of heart failure. This was based on data in an article that concluded DPP-4 inhibition with saxagliptin did not increase or decrease the rate of ischemic events, though the rate of hospitalization for heart failure was increased. Although saxagliptin improves glycemic control, other approaches are necessary to reduce cardiovascular risk in patients with diabetes. Saxagliptin is used as monotherapy or in combination with other drugs for the treatment of type 2 diabetes. It does not appear to decrease the risk of heart attacks or strokes. It increases the risk of hospitalization for heart failure by ...

Dipeptidyl peptidase-4 inhibitors, such as saxagliptin, have been reported to have beneficial effects on β-cell function, but the specific underlying mechanism remains unclear. Stromal cell-derived factor-1α (SDF-1α), a chemokine produced in multiple organs, has been considered as a crucial regulator in promoting β-cell survival. Here, we speculate that SDF-1α might mediate the effect of saxagliptin on improving β-cell function. After 12-week saxagliptin treatment in high-fat diet/streptozotocin-induced diabetic rats, significant improvement in pancreas insulin secretion capacity evaluated by hyperglycemia clamp and increased β-cell to α-cell areas ratio were observed. Saxagliptin significantly induced β-cell proliferation and upregulated the expression of proliferation-related factors including c-myc and cyclind D1 determined with western blotting from the isolated islets. The expression/activity of DPP-4 was significantly reduced and paralleled with the restoration of SDF-1α levels in the

Longer term gliptin dataLonger term gliptin data
Diabetes, Obesity and Metabolism has published the results of a long term study comparing vildagliptin to glimepiride.. The study recruited 2,789 patients who were inadequately controlled on metformin monotherapy. Participants were then randomised to vildagliptin 50mg twice daily or glimepiride titrated up to 6mg daily. These results are a prespecified interim analysis after 52 weeks to ensure that vildagliptin is non-inferior to glimepiride.. Baseline HbA1c was 7.3% in both groups. This fell by 0.44% in the vildagliptin arm and 0.53% in the glimepiride arm. The difference was not significant and therefore non-inferiority was proven.. Other notable differences reported include a lower incidence of hypoglycaemia in the patients receiving vildagliptin and beneficial effects on body weight. Patients treated with vildagliptin lost approximated 0.23kg compared to a weight gain of 1.56kg in the glimepiride cohort. Additionally, no major differences were noted in haematological or biochemical ...

In the framework of real structures, i.e. finite sized systems, the transition from a molecule (hydrocarbon) to a true allotrope is ill-defined. For hexagonal systems, it is universally accepted that benzene is a molecule and not a carbon allotrope. This also holds for coronene and higher oligoacenes and, in principle, as long as the fraction of heteroatoms (mainly hydrogen) does not reach zero. However, what we consider to be graphene and even graphite or other allotropes of carbon, still contain finite fractions of heteroatoms (e.g. nitrogen impurities in diamond).. The same scenario holds for systems with tetrahedrally coordinated carbon. When the size of a diamond crystal is so small that the fraction of hydrogen atoms saturating the dangling bonds of the surface carbon atoms cannot be neglected, we are prone to consider it as a molecule: a diamondoid. The smallest diamondoid is adamantane, formed by a carbon cage of ten carbon atoms (C10H16). Higher diamondoids have multiples of four ...

Objective: DPP4 inhibitors (DPP-4i) lower blood glucose in diabetic subjects however the mechanism of action through which these agents improve glucose homeostasis remains incompletely understood. Although GLP-1 and GIP represent important targets for DPP4 activity, whether additional substrates are important for the glucose-lowering actions of DPP4 inhibitors remains uncertain.. Research Design and Methods: We examined the efficacy of continuous vildagliptin administration in wildtype (WT) and dual incretin receptor knockout (DIRKO) mice after 8 weeks of a high fat (HF)-diet.. Results: Vildagliptin had no significant effect on food intake, energy expenditure, body composition, body weight gain or insulin sensitivity in WT or DIRKO mice. However glycemic excursion after oral glucose challenge was significantly reduced in WT but not in DIRKO mice after vildagliptin treatment. Moreover, vildagliptin increased levels of glucose-stimulated plasma insulin, and reduced levels of cholesterol and ...

5143 Here we describe a novel pharmacologically-induced death pathway in tumor cells involving c-Jun upregulation and caspase-dependent c-Abl cleavage using the tyrophostin adaphostin (NSC680410) as a tool compound.. Adaphostin has been previously studied as a bcr-abl inhibitor in CML. However its role in MM is unknown. After demonstrating its anti-myeloma cytotoxicity, expression profiling of adaphostin-treated MM cells was carried out to identify its molecular targets. Surprisingly, c-Jun was the most upregulated gene even at the earliest point of analysis (2 hours). Subsequently, adaphostin-induced c-Abl cleavage was observed in immunoblot analysis. Proteasome inhibitor bortezomib, but not melphalan or dexamethasone, induced similar effects, indicating unique agent-dependent mechanisms. Using caspase inhibitors as well as caspase-resistant mutants of c-Abl (TM-c-Abl and D565A-Abl), we then showed that c-Abl cleavage in MM cells requires caspase activity. Importantly, both overexpression of ...

Press Release issued Dec 6, 2016: Diabetes is the chronic condition associated with abnormally high level of glucose in the blood. Insufficient or non production of insulin in pancreas causes diabetes. Globally, the incidence of diabetes is increasing significantly and it is becoming a major burden. According to World Health Organization (WHO), approximately 221 million people are suffering from diabetes. There are large numbers of blood glucose lowering drugs. Saxagliptin is an oral anti-diabetic agent known as DPP IV inhibitor. DDP IV inhibitor is an enzyme helps in suppressing the release of glucagon. Saxagliptin is used for medication of diabetes, as to boost the amount of insulin in the body produced after meal. Saxagliptin is marketed under the brand name Onglyza. Saxagliptin acts on natural hormone in the body known as incretins.

CMU Intellectual Repository: Vildagliptin reduces cardiac ischemic-reperfusion injury in obese orchiectomized ratsCMU Intellectual Repository: Vildagliptin reduces cardiac ischemic-reperfusion injury in obese orchiectomized rats
2016 Society for Endocrinology. Obesity and testosterone deprivation are associated with coronary artery disease. Testosterone and vildagliptin (dipeptidyl peptidase-4 inhibitors) exert cardioprotection during ischemic-reperfusion (I/R) injury. However, the effect of these drugs on I/R heart in a testosterone-deprived, obese, insulin-resistant model is unclear. This study investigated the effects of testosterone and vildagliptin on cardiac function, arrhythmias and the infarct size in I/R heart of testosterone-deprived rats with obese insulin resistance. Orchiectomized (O) or sham operated (S) male Wistar rats were divided into 2 groups to receive normal diet (ND) or high-fat diet (HFD) for 12 weeks. Orchiectomized rats in each diet were divided to receive testosterone (2 mg/kg), vildagliptin (3 mg/kg) or the vehicle daily for 4 weeks.

Malaria remains a major disease in the developing world and globally is the most important parasitic disease causing significant morbidity and mortality. Because of widespread resistance to conventional antimalarials, including chloroquine (CQ), new drugs are urgently needed. Here we report on the antimalarial efficacy, both in vitro and in vivo, of a series of aminoquinoline derivatives with adamantane or benzothiophene as a carrier. In vitro efficacy was evaluated by a lactate dehydrogenase (LDH) assay in cultures of a CQ-sensitive (3D7) and CQ-resistant (Dd2) strain of Plasmodium falcipanim. Of a series of 26 screened compounds, 12 that exerted a growth inhibition rate of ,= 5% were further examined in vitro to determine the 50% inhibitory concentration (IC50) values. Nine compounds shown in preliminary experiments to be non-toxic in vivo were evaluated in C57BL/6 mice infected with Plasmodium herghei ANKA strain using a modified Thompson test. All nine compounds examined in vivo pr...olonged ...

The collision induced decompositions of 3-substituted adamantane carboxylate anions have been studied with a view to uncovering charge-remote fragmentations of the 3-substituent. The 3-substituent is chosen so that it cannot approach the anion site, and so any fragmentations of that substituent should proceed independently of the charged centre, viz. charge-remote reactions. The following systems have been studied (i) the 3-cyclohexenyl system shows no charge-remote retro Diels-Alder fragmentation (DeltaH = +157 kJ mol(-1)), instead, charge-remote loss of the cyclohexenyl radical is noted, (ii) the 3-isobutyl ketone system shows no Norrish II cleavage (loss of C(3)H(6), DeltaH = +18 kJ mol(-1)), instead, the competitive losses of CO(2) from the charged carboxyl centre, together with charge-remote radical loss of the 3-substituent are observed, and (iii) the corresponding 3-isopropyl ester does show the Norrish II loss of C(3)H(6), together with competitive losses of CO(2) and the ...

This is an open-label study of ZYC300 in the treatment of advanced stage malignancy of the kidney in patients who have not had previous immune-based therapies or treatment of advanced stage malignancies (cancerous growths) of the ovary, breast, colon, or hormone-refractory prostate in patients who have failed at least one but no more than two prior regimens of chemotherapy. Patients who meet all entry criteria will be administered 600 mg/m^2 cyclophosphamide intravenously 3 days before each dose of ZYC300. ZYC300 will be administered at 400 micrograms DNA/total dose every two weeks for a maximum of six doses (6 cycles).. ZYC300 is a plasmid DNA formulated within biodegradable microencapsulated particles. This is the first time that ZYC300 and Cyclophosphamide will be given together. Cyclophosphamide is a chemotherapy drug approved by the FDA that has been used for many years in many different kinds of cancer. In this trial the study drug will be used to boost the immune system.

Distribution and dynamics of adamantanes in a lipid bilayer. - Oxford NeuroscienceDistribution and dynamics of adamantanes in a lipid bilayer. - Oxford Neuroscience
The adamantanes are a class of compounds that have found use in the treatment of influenza A and Parkinsons disease, among others. The mode of action for influenza A is based on the adamantanes interaction with the transmembrane M2 channel, whereas the treatment of Parkinsons disease is thought to relate to a channel block of N-methyl-D-aspartate receptors. An understanding of how these compounds interact with the lipid bilayer is thus of great interest. We used molecular-dynamics simulations to calculate the potential of mean force of adamantanes in a lipid bilayer. Our results demonstrate a preference for the interfacial region of the lipid bilayer for both protonated and deprotonated species, with the protonated species proving significantly more favorable. However, the protonated species have a large free-energy barrier in the center of the membrane. In contrast, there is no barrier (compared with aqueous solution) at the center of the bilayer for deprotonated species, suggesting that the

Current Research into Cures for Type-1 Diabetes: 2016Current Research into Cures for Type-1 Diabetes: 2016
Its important to remember that individual cells do not last as long as people live. Cells naturally die and new cells grow within your body all the time. Research (mostly in animals) has suggested that Vildagliptin might have two separate effects on beta cells. On the one hand, it seems to cause beta cells to naturally divide and grow, and on the other hand, it seems to delay beta cells natural death, so they live longer. Both of these effects may be important to curing type-1 diabetes, but it is not clear. This is why research is important. For example, even if Vildagliptin triggers a divide-and-grow reaction, it will only be effective if there are some beta cells to start with, and we just dont know if there are enough to get things started. On the cell death side, if the autoimmune attack directly kills beta cells, then stopping natural cell death may have little impact. Those cells will be killed by autoimmunity before they can die of old age. However, if the autoimmune attack works ...
