Nonpeptidic SH2 inhibitors of the tyrosine kinase ZAP-70
摘要:
The synthesis of a series of 1,2,4-oxadiazole analogs is discussed along with their ZAP-70 SH2 inhibitory activity. The tyrosine moiety in the original series has been replaced with nonpeptidic functional groups without a substantial loss of binding affinity. (C) 1999 Elsevier Science Ltd. All rights reserved.

crystallography of the inhibitors binding to the TACE enzyme demonstrates that each series derives its activity from the opposite enantiomer of the cyclopropyl scaffolds, which display almost superimposable hydroxamate groups that coordinate to the zinc at the catalytic site. Mode A inhibitors occupy the S1'-S3' binding pockets, whereas mode B resides in the nonprime binding sites.
