Pyrido[2,3-b][1,4]oxazines or tetrahydropyrido[2,3-b][1,4]oxazepines as IAP antagonists

Abstract

Disclosed herein are novel 2,3-dihydro-1H-pyrido[2,3-b][1,4]oxazine or 1,2,3,4-tetrahydropyrido[2,3-b][1,4]oxazepine derivatives used as antagonists of IAPs (Inhibitors Apoptosis Proteins), also known as Smac mimetics. Disclosed herein is the use of these antagonists for inducing or sensitizing cells to the induction of apoptotic cell death, and the use of such compounds for treating proliferative disease such as cancer.
