The present invention is directed to 3-amino-4-phenylbutanoic acid derivatives which are inhibitors of the dipeptidyl peptidase-IV enzyme (“DP-IV inhibitors”) and which are useful in the treatment or prevention of diseases in which the dipeptidyl peptidase-IV enzyme is involved, such as diabetes and particularly type 2 diabetes. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which the dipeptidyl peptidase-IV enzyme is involved.
Solution-phase automated parallel synthesis of a Tie-based library is described. This library comprising 2560 members, was obtained from the combination of 80 carboxylic acids and 32 amines and was screened against Tc80 protease, a parasitic prolyl endopeptidase secreted by Trypanosoma cruzi. Pyrrolidine derivatives proved the most potent inhibitors with IC50 values found in the low nanomolar range. (C) 1999 Elsevier Science Ltd. All rights reserved.
