The transferred nuclear Overhauser effect has been used to determine the biologically active conformations of two stromelysin inhibitors. Both inhibitors used in this study were hydroxamic acids generated via chemical synthesis. These structures, representing the conformation of each inhibitor bound to stromelysin, superimposed with excellent agreement. The study also provided information on th...

Microsomal prostaglandin E(2) synthase-1 (mPGES-1) catalyzes prostaglandin E(2) formation and is considered as a potential anti-inflammatory pharmacological target. To identify novel chemical scaffolds active on this enzyme, two pharmacophore models for acidic mPGES-1 inhibitors were developed and theoretically validated using information on mPGES-1 inhibitors from literature. The models were u...

The melting curves of fatty acid amide hydrolase (FAAH) in the presence of 29 reversible inhibitors were measured using a thiol-reactive fluorophore. The thermal stability (T(m)) of the FAAH/inhibitor complex varied significantly depending on the chemical characteristics of the inhibitors, notably variations in the head group. Two separate distributions were observed when T(m) was plotted again...

Metal-carbon nanocomposites have been investigated as additives to enhance the protective effect of corrosion inhibitors. Two inhibitors were used Inhibitor VNH-L-113 (1-morpholinomethylcyclohexylamine) belongs Schiff bases, which are known in neutral and acidic media. SNPKh-1004 is often practice protection oil gas industry. For research, an electrochemical method was applied using rate meters...

combination therapy with clomiphene citrate plus gonadotropin (clomiphene citrate plus hmg) in induction ovulation reduce the gonadotropins dose but antiestrogenic effect of c.c. can decrease pregnancy rate. in a randomized clinical trial we compared 3 treatment protocol for induction ovulation and intra uterine insemination (i/o plus iui) in women with infertility history more than one year, n...

Until 2004, many researchers believed that protein methylation in eukaryotic cells was an irreversible reaction. However, the discovery of lysine-specific demethylase 1 in 2004 drastically changed this view and the concept of chromatin regulation. Since then, the enzymes responsible for lysine demethylation and their cellular substrates, biological significance, and selective regulation have be...
