CC-90011 benzenesulfonate is a potent, selective, reversible and orally active inhibitor of lysine specific demethylase-1 (LSD1) with an IC50 of 0.25 nM. CC-90011 benzenesulfonate is less enzymatic inhibition against LSD2, MOA-A, and MAO-B. CC-90011 benzenesulfonate induces acute myeloid leukemia (AML) and small cell lung cancer (SCLC) cells differentiation and has potent anticancer activity.IC50 & Target: IC50: 0.25 nM (LSD1)In Vitro: CC-90011 (Compound 11) shows potent induction of on-target cellular differentiation marker CD11b in THP-1 cell line with an EC50 of 7 nM, antiproliferative activity in AML kasumi-1 cells with an EC50 of 2 nM.
Suppression of GRP is observed with treatment of CC-90011 (4 days) in a dose-dependent manner and at pharmacologically useful concentrations (EC50=3 nM, H209 and 4 nM, H1417). CC-90011 (12 days) treatment of SCLC cells results in potent antiproliferative activity (EC50=6 nM, H1417) that correlated with GRP suppression.In Vivo: CC-90011 (5 mg/kg; oral administration; daily; for 30 days; for 30 days) treatment inhibits tumor growth in patient-derived xenograft SCLC models.
CC-90011 (once a day; for 4 days) treatment results in robust downregulation of GRP mRNA levels at 2.5 mg/kg and maximum suppression of GRP at 5 mg/kg in a SCLC human tumor xenograft (H1417) mice.
After i.v. administration, CC-90011 (Compound 11; 5 mg/kg) has systemic clearance of 32.4 mL/min/kg, elimination half-life of 2 h, and a high volume of distribution of 7.5 L/kg. CC-90011 (Compound 11; 5 mg/kg) is readily absorbed after oral administration with an AUC0-24h of 1.8 μM·h, C/sub>max of 0.36 μM, and oral bioavailability of 32%.
