The compound Neu5Ac3alphaF-DSPE (4), in which the C-3 position was modified with an axial fluorine atom, inhibited the catalytic hydrolysis of influenza virus sialidase and the binding activity of hemagglutinin. The inhibitory activities to sialidases were independent of virus isolates examined. With the positive results obtained for inhibition of hemagglutination and hemolysis induced by A/Aic...

A series of novel alkynyl substituted 3,4-dihydropyrimidin-2(1H)-one (DHPM) derivatives were designed, synthesized and evaluated in vitro as potential inhibitors of chorismate mutase (CM). All these compounds were prepared via a multi-component reaction (MCR) involving sequential I2-mediated Biginelli reaction followed by Cu-free Sonogashira coupling. Some of them showed promising inhibitory ac...

Structure-activity relationship studies were conducted on Irosustat (STX64, BN83495), the first steroid sulfatase (STS) inhibitor to enter diverse clinical trials for patients with advanced hormone-dependent cancer. The size of its aliphatic ring was expanded; its sulfamate group was N,N-dimethylated, relocated to another position and flanked by an adjacent methoxy group; and series of quinolin...

Two ergostanes, 5α,8α-epidioxy-22E-ergosta-6,22-dien-3β-ol (1) and 5α-ergost-7,22-dien-3β-ol (2), and a lanostane, 3β-hydroxylanostan-8,24-diene-21-oic acid (trametenolic acid) (3), were isolated from an n-hexane extract prepared from the fruiting body of Trametes versicolor (Bres. Rivarden). The activity of the isolated sterols was evaluated against promastigotes and amastigotes of Leishmania ...

BACKGROUND Subclinical myocardial injury, as measured by high-sensitivity cardiac troponin T (hsTnT), and myocardial stress, as measured by N-terminal pro-B-type natriuretic peptide (NT-proBNP), are related to glycemic control in patients with type 2 diabetes mellitus, and are strong predictors of adverse cardiovascular outcomes. We sought to determine whether antihyperglycemic therapy improves...

FIG. 1. Effect of incr-easing substrate concentrations upon the magnitude of reaction with three influenza virus enzymes. Substrate in 0.5 si phosphate-buffered saline (PBS), pH 6 as indicated, and PBS to a total of 0.25 ml (human ac-GP, 4 mg/ ml; ovo, 40 mg/nil; PSM, 30 mg/ml), 0.05 ml of enzyme. Enzymes for these studies were virus concentrates prepared from infected chorioallantoic fluid by ...

completely novel structure in this class of compounds. Fermentation and Isolation Cremeomycinwas originally reported by Bergy and Pyke at the Upjohn Company in 1967 from Streptomyces cremeus NRRL3241.11} Neither a structural formula nor functional group information was reported. Physico-chemical and Biological Properties Cremeomycinis a bright yellow solid that is soluble in solvents from dichl...

Gender diverse individuals who do not conform to society’s binary gender expectations are more likely experience difficulties in acceptance and recognition of gender, compared binary-identifying transgender people. This may accentuate the feeling that their identity is socially recognized or validated. study aimed investigate psychological functioning among adolescents adults identify beyond sp...

ABSTRACT The present study aimed to investigate the morbidity and mortality associated with most common diseases during rearing period of Holstein calves in a high-production dairy farm. (n = 600) were allocated three groups based on age: G1 (1-7 days, n 216), G2 (30-40 188), G3 (69-85 196). They evaluated over 60 days at eight different times. rates 47.67% (286/600) for diarrhea, 73.00% (438/6...

The purpose of this study was to characterize the kinetics and voltage-dependence of the block of N-methyl-D-aspartate (NMDA)-induced currents in primary cultures of rat cortical neurons by the neuroprotective, low-affinity, NMDA antagonist ARL 15896AR, using whole-cell voltage-clamp techniques. ARL 15896AR caused rapid and reversible inhibition of NMDA (50 microM)-evoked currents from neurons ...
