SMO-IN-6
Anticancer agent 321 is a Smoothened (SMO) inhibitor with a human IC50 of 0.12 μM, enhanced aqueous solubility, good plasma and metabolic stability, moderate therapeutic index, preliminary safety profile, and moderate oral bioavailability in rats.Anticancer agent 321 binds to SMO’s 7-transmembrane helical channel, forming hydrogen bonds with Asp384 and hydrophobic/π-π interactions with His470, Phe391, Tyr394, stabilizing SMO’s inactive conformation to inhibit Hedgehog/GLI signaling.Anticancer agent 321 inhibits proliferation, suppresses colony formation, induces apoptosis, and downregulates Hedgehog/GLI pathway target genes GLI1, GLI2, Ptch1, HHip in cancer cells.Anticancer agent 321 inhibits tumor growth, downregulates Ki67 and SOX2, and upregulates cleaved-caspase 3 in tumor tissues.Anticancer agent 321 can be used for the research of cutaneous squamous cell carcinoma.

Biological Activity
SMO-IN-6 (Compound 16) (72 h) potently inhibits the proliferation of A431 cutaneous squamous cell carcinoma cells, with a GI50 of 1.4 μM and a therapeutic index of 31 relative to non-tumorigenic HaCaT skin cells[1].
SMO-IN-6 (1-4 μM; 14 days) inhibits long-term colony formation of A431 cutaneous squamous cell carcinoma cells in a dose-dependent manner, with an inhibition rate exceeding 95% at 4 μM[1].
SMO-IN-6 (1 μM) potently downregulates the expression of Hedgehog/GLI pathway target genes Gli1, Gli2, Ptch1 and HHip in A431 cutaneous squamous cell carcinoma cells[1].
SMO-IN-6 (1-4 μM; 16 h) induces apoptosis in A431 cutaneous squamous cell carcinoma cells in a dose-dependent manner, with the apoptosis rate reaching 93% at the concentration of 4 μM[1].
