RU-SKI 43 hydrochloride is a potent and selective Hedgehog acyltransferase (Hhat) inhibitor with an IC₅₀ of 850 nM. RU-SKI 43 hydrochloride reduces Gli-1 activation through Smoothened-independent non-canonical signaling and decreases Akt and mTOR pathway activity. RU-SKI 43 hydrochloride has anti-cancer activity^[1].

IC50: 850 nM (Hhat)^[1]

RU-SKI 43 hydrochloride (10 μM; for 6 days) strongly decreases cell proliferation (83% in AsPC-1 cells) in AsPC-1 and Panc-1 cells^[2].
RU-SKI 43 hydrochloride (10 or 20 μM; 5 hours) causes dose-dependent inhibition of Shh palmitoylation following only 5 hours^[1].
RU-SKI 43 hydrochloride (10 μM; for 72 hours) causes a 40% decrease in Gli-1 levels in AsPC-1 cells^[2].
RU-SKI 43 hydrochloride (10 μM; 48 hours) results in decreased phosphorylation (47-67%) of four proteins in the Akt pathway, including Akt (phosphorylation at both Thr307 and Ser473), PRAS40, Bad and GSK-3β. RU-SKI 43 treatment also decreases phosphorylation of mTOR and S6, members of the mTOR signaling pathway^[2].
RU-SKI 43 hydrochloride behaves as an uncompetitive inhibitor (K_i=7.4 μM) with respect to Shh, and as a noncompetitive inhibitor (K_i=6.9 μM) with respect to ¹²⁵I-iodo-palmitoylCoA^[1].
