Samuraciclib (CT7001) 是一种有效的,具有选择性,ATP 竞争性和口服活性的CDK7抑制剂,IC50为 41 nM。Samuraciclib 对CDK7的选择性分别是 CDK1,CDK2 (IC50为 578 nM),CDK5 和 CDK9 的 45 倍,15 倍,230 倍和 30 倍。Samuraciclib 以 GI50值为 0.2-0.3 μM 来抑制乳腺癌细胞系的生长,具有有效的抗肿瘤作用。
生物活性 | Samuraciclib (CT7001) is a potent, selective, ATP-competitive and orally activeCDK7inhibitor, with anIC50of 41 nM. Samuraciclib displays 45-, 15-, 230- and 30-fold selectivity overCDK1,CDK2(IC50of 578 nM),CDK5andCDK9, respectively. Samuraciclib inhibits the growth of breastcancercell lines with GI50values between 0.2-0.3 μM. Samuraciclib has anti-tumor effects[1][2]. |

体外研究 (In Vitro) | Samuraciclib (ICEC0942; 0-10 μM; 24 hours; HCT116 cells) treatment promotes cell apoptosis[1]. Samuraciclib (ICEC0942; 0-10 μM; 24 hours; HCT116 cells) treatment induces cell cycle arrest[1]. Samuraciclib (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 also inhibits phosphorylation of CDK1, CDK2 and retinoblastoma[1]. Samuraciclib (ICEC0942) 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].

体内研究 (In Vivo) | Samuraciclib (ICEC0942; 100 mg/kg; oral gavage; daily; for 14 days; female nu/nu-BALB/c athymic nude mice) 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) and ICI 47699 treatment shows complete growth arrest of estrogen receptor (ER)-positive tumor xenografts[1].
Animal Model: | Female nu/nu-BALB/c athymic nude mice (7-week old) with MCF7 cells[1]. | Dosage: | 100 mg/kg | Administration: | Oral gavage; daily; for 14 days | Result: | At day 14, tumor growth was inhibited by 60%. |
