Samuraciclib hydrochloride hydrate (ICEC0942; 0-10 μM; 24 hours; HCT116 cells) treatment induces cell cycle arrest^[1].
Samuraciclib hydrochloride hydrate (ICEC0942; 0-10 μM; 0-24 hours; HCT116 cells) treatment inhibits the phosphorylation of PolII CTD in a dose and time dependent manner in HCT116 colon cancer cells. Samuraciclib trihydrochloride also inhibits phosphorylation of CDK1, CDK2 and retinoblastoma^[1].
Samuraciclib (ICEC0942) hydrochloride hydrate inhibits the growth of MCF7, T47D, MDA-MB-231, HS578T, MDA-MB-468, MCF10A and HMEC cells with GI₅₀values of 0.18 μM, 0.32 μM, 0. 33 μM, 0.21 μM, 0.22 μM, 0.67 μM and 1.25 μM, respectively^[1].

Samuraciclib (ICEC0942; 100 mg/kg; oral gavage; daily; for 14 days; female nu/nu-BALB/c athymic nude mice) hydrochloride hydrate treatment inhibits tumor growth by 60% at day 14, and is accompanied by highly significant reductions in PolII Ser2 and Ser5 phosphorylation in PBMCs and in tumors^[1].
The combination of Samuraciclib (ICEC0942) hydrochloride hydrate and ICI 47699 treatment shows complete growth arrest of estrogen receptor (ER)-positive tumor xenografts^[1].
