Abstract:
HG-7-85-01(22) and HG-7-86-01(26) are thiazolo5,4-b]pyridine containing type II tyrosine kinase inhibitors with potent cellular activity against both wild-type and 'gatekeeper' mutant T315I- Bcr-Abl. Here we report on the 'hybrid design' concept and subsequent structure activity guided optimization efforts that resulted in the development of these inhibitors.
