Abstract

Abnormal activation of the Hh pathway has been linked to sevral types of human cancers, and the development of small-molecule inhibitors of this pathway represents a promising route towards novel anti-cancer therapeutics. A cell-base screen performed in our laboratories identified a new class of Hh pathway inhibitors, 1-amino-4-benzylphthalazines, that act via antagonism of the Smoothened receptor. A variety of analogs were synthesized and their structure-activity relationships determined. This optimization resulted in the discovery of high affinity Smoothened antagonists, one of which was further profiled in vivo. This compound displayed a good pharmacokinetic profile and also offered tumor regression in a genetic mouse model of medulloblastoma.
