Synthesis and in vitro evaluation of a series of diketopiperazine inhibitors of plasminogen activator inhibitor-1
摘要:
We have synthesized and evaluated a series of diketopiperazine-based inhibitors of PAI-1. These studies resulted in the identification of 34 which inhibited PAI-1 in vitro with an IC50 = 0.2 muM. The synthesis and SAR of these compounds are described. (C) 2001 Elsevier Science Ltd. All rights reserved.

A diketopiperazine of formula (I): ##STR1## wherein each of R.sub.7 and R.sub.8 which may be the same or different; is hydrogen or a nitro group; Y is ##STR2## --O-- or --S--, wherein each of R.sub.9 and R.sub.10 which may be the same or different, is hydrogen or a nitro group; n is 0, 1 or 2; m is an integer of 1 to 6; each R.sub.6, which may be the same or different, is a C.sub.1 -C.sub.6 alkyl group; and X is selected from (i) a phenyl group of the following formula ##STR3## and the salts and esters thereof; have activity as inhibitors of plasminogen activator inhibitor.
