Synthesis of 1-(4-acyloxybenzoyloxyacetyl)-4-alkylpiperazines and 1-(4-acyloxybenzoyl)-4-alkylpiperazines as inhibitors of chymotrypsin
摘要:
Sixteen new esters and amides of 4-acyloxybenzoic acids were prepared and screened as chymotrypsin inhibitors. Inhibiting activities on chymotrypsin differed markedly (> 100-0.008 mu M). Compounds which contained the 4-benzoyloxyacetyl moiety showed considerably higher activity then 4-acyloxybenzamides. Compounds 1c and 11f are also weak trypsin inhibitors.

Seventeen new compounds of 4-(4-guanidinobenzoyloxy)benzamides and 4-(4-guanidinobenzoyloxy)benzoyloxyacetamides were prepared and their inhibitory activities on trypsin, thrombin and porcine pancreatic elastase were measured. These compounds were found to be selective trypsin inhibitors with inhibiting activities from 0.44 to 43 mu M.

Efforts to re. ne the SAR of the piperazinyl-glutamate-pyridines for more potent analogs with improved pharmacokinetic profiles are described. Exploring substituted piperidines and other ring systems at the 4-pyridyl position led to compounds with improved potency and pharmacokinetic properties over candidate I. In particular, compounds 4t and 5t were discovered with a 10-fold improvement over potency and improved pharmacokinetic profiles in both the rat and dog. (C) 2010 Elsevier Ltd. All rights reserved.
