Discovery of nonbenzamidine factor VIIa inhibitors using a biaryl acid scaffold
摘要:
In this Letter, we describe the synthesis of several nonamidine analogs of biaryl acid factor VIla inhibitor 1 containing weakly basic or nonbasic P1 groups. 2-Aminoisoquinoline was found to be an excellent surrogate for the benzamidine group (compound 2) wherein potent inhibition of factor VIla is maintained relative to most other related serine proteases. In an unanticipated result, the m-benzamide P1 (compounds 21a and 21b) proved to be a viable benzamidine replacement, albeit with a 20-40 fold loss in potency against factor Vlla.

The solid-phase synthesis of a library based on an unusual biphenyl-containing trypsin-likeserineproteaseinhibitor is described. Key to this effort was the synthesis of a highly functionalized aryl boronic acid reagent which required the development of a novel and efficient method to convert a triflate to a pinacolboronate in large scale.
