2-Mercaptoimidazoles, a new class of potent CCR2 antagonists
摘要:
We describe the synthesis and SAR of a new class of CCR2 antagonists based on a 2-mercaptoimidazole scaffold. The initial lead 1a was optimized to the 3,4-disubstituted analogues 1p-(S) and 1q-(S), which have IC50 values in the MCP-1 induced Ca-flux below 0.01 muM. (C) 2004 Elsevier Ltd. All rights reserved.

An approach to the parallel synthesis of hydantoin libraries by reaction of in situ generated 2,2,2-trifluoroethylcarbamates and α-amino esters was developed. To demonstrate utility of the method, a library of 1158 hydantoins designed according to the lead-likeness criteria (MW 200–350, cLogP 1–3) was prepared. The success rate of the method was analyzed as a function of physicochemical parameters

We have discovered two related chemical series of nonpeptide urotensin-II (U-II) receptor antagonists based oil piperazino-phthalimide (5 and 6) and piperazino-isoindolinone (7) scaffolds. These structure types are distinctive from those of U-II receptor antagonist series reported in the literature. Antagonist 7a exhibited single-digit nanomolar potency in rat and human cell-based functional assays, as well as strong binding to the human U-II receptor. In advanced pharmacological testing, 7a blocked the effects of U-II in vitro in a rat aortic ring assay and in vivo in it rat ear-flush model. A discussion of U-II receptor antagonist pharmacophores is presented, and it specifically defined model is suggested from tricycle 13, which has it high degree of conformational constraint.
