Molecular design and structure–Activity relationships leading to the potent, selective, and orally active thrombin active site inhibitor BMS-189664
摘要:
A series of structurally novel small molecule inhibitors of human alpha -thrombin was prepared to elucidate their structure-activity relationships (SARs), selectivity and activity in vivo. BMS-189664 (3) is identified as a potent, selective, and orally active reversible inhibitor of human alpha -thrombin which is efficacious in vivo in a mouse lethality model, and at inhibiting both arterial and venous thrombosis in cynomolgus monkey models.

This invention relates to compounds which are generally alpha1B-receptor antagonists, and which are represented by Formula (I):
wherein X, Y, and R1 are as defined in the specification, or individual isomers or racemic or non-racemic mixtures of isomers, or pharmaceutically acceptable salts or solvates thereof. The invention further relates to pharmaceutical compositions containing such compounds, and methods for their use as therapeutic agents.

The discovery of a novel series of NR2B subtype selective N-methyl-d-aspartate (NMDA) antagonists is reported. Initial optimization of a high-throughput screening lead afforded an aminopyridine derivative 13 with significant NR2B antagonist potency but limited selectivity over hERG-channel and other off-target activities. Further structure-activity studies on the aminoheterocycle moiety and optimization

opioid peptide analogues. Concerning the diamine spacer, conformational constraints imposed by 4-aminopiperidine and 4-(aminomethyl)piperidine as well as the presence of a hydroxyl group eliminated activity, but the presence of gem-dimethylsubstitution next to the nitrogen attached to Tyr increased activity substantially for the D-Phe derivatives. Removal of the N-acetyl group from Phe did not eliminate
compounds able to co-target the CD73 and the A2A adenosine receptor (A2A AR) as dual-blockers of adenosine generation and activity. The design project was to combine in the same molecule the thiazolo[5,4-d]pyrimidine core, an essential pharmacophoric feature to block the A2A AR, with a benzenesulfonamide group which is a characteristic group of CD73 inhibitors. Most of the reported compounds resulted in

A series of conformationally restricted inhibitors of human soluble epoxide hydrolase (sEH) has been developed. Inhibition potency of the described compounds ranges from 4.2 microM to 1.1 nM against recombinant sEH. N-(1-Acetylpiperidin-4-yl)-N'-(adamant-1-yl) urea (5a) was found to be a potent inhibitor (IC(50) = 7.0 nM) that was also orally bioavailable in canines.
