TL;DR: By identifying a drug combination that delays or even combats development of resistance when used as a first-line treatment in clinical trials, these results could ultimately improve the lives of patients with medulloblastoma or other cancers that depend on Smo for their survival.

TL;DR: Structural-activity relationship studies led to the discovery of a potent and specific Smoothened antagonist N-(6-((2S,6R)-2,6-dimethylmorpholino)pyridin-3-yl)-2-methyl-4'-(trifluoromethoxy)biphenyl- 3-carboxamide (5m, NVP-LDE225), which is currently in clinical development.

TL;DR: Findings show a crucial cell-intrinsic role for Hedgehog signaling in the development and maintenance of SCLC and identify Hedgehog pathway inhibition as a therapeutic strategy to slow the progression of disease and delay cancer recurrence in individuals with S CLC.

TL;DR: A cell-based screen performed in the laboratories identified a new class of Hh pathway inhibitors, 1-amino-4-benzylphthalazines, that act via antagonism of the Smoothened receptor that displayed a good pharmacokinetic profile and also afforded tumor regression in a genetic mouse model of medulloblastoma.

TL;DR: It is shown that active Wnt/β-catenin signaling is required for maintenance of colorectal tumor xenografts harboring APC mutations and this results support efforts to treat human coloreCTal cancer by pharmacological inhibition of the Wnt /β- catenin pathway.
