RU-SKI 43 (hydrochloride)

Hedgehog acyltransferase (Hhat) is an N-palmitoyltransferase that acylates Sonic hedgehog (Shh), which is critical for signaling through Shh. RU-SKI 43 is an inhibitor of Hhat (IC50 = 0.85 µM). It blocks palmitoylation of Shh without affecting palmitoylation of H-Ras or Fyn, myristoylation of c-Src, or acylation of Wnt3a. RU-SKI 43 is cell-permeable and inhibits both autocrine and paracrine Shh-induced activation of Gli-mediated transcription. In pancreatic cancer cells, RU-SKI 43 reduces both Gli1 activation and proliferation.Formal Name: 1-[6,7-dihydro-4-[(3-methylphenoxy)methyl]thieno[3,2-c]pyridin-5(4H)-yl]-2-[(2-methylbutyl)amino]-ethanone, monohydrochloride.
