Tetrahydroisoquinoline amide substituted phenyl pyrazoles as selective Bcl-2 inhibitors

Bioorg Med Chem Lett. 2009 Jan 1;19(1):230-3. doi: 10.1016/j.bmcl.2008.10.113. Epub 2008 Oct 31.


Anti-apoptotic Bcl-2 protects cells from apoptosis by binding to pro-apoptotic members of the Bcl-2 family thereby playing a role in tumour survival in response to chemo- or radiation therapy. We describe a series of phenyl pyrazoles that have high affinity for Bcl-2 and rationalise the observed SAR by means of an X-ray crystal structure.
