生物活性:
Trilaciclib (G1T28) is an orally active CDK4/6 inhibitor with IC50 values of 1 nM and 4 nM for CDK4 and CDK6, respectively. . Trilaciclib can effectively inhibit tumor cell proliferation and reduce the hematological toxicity caused by chemotherapy. Trilaciclib attenuates apoptosis and myelosuppression induced by 5FU (HY-90006) chemotherapy.

体内研究:
Trilaciclib (50-150 mg/kg;口服;单剂量) 可保护小鼠骨髓细胞免受化疗诱导的细胞凋亡,并以剂量依赖性减轻体内化疗诱导的骨髓抑制。Trilaciclib 在 150 mg/kg 剂量下,可以减少 5FU (HY-90006) (150 mg/kg; ip) 化疗引起的 HSPC 损伤,从而加速化疗后血细胞计数的恢复。Animal Model:FVB/n female C57Bl6 mice
Dosage:50, 100, 150 mg/kg
Administration:Po; single dose; treated followed 11 or 23 hours later by a single injection of EdU (HY-118411) (100 μg; ip); mouse were euthanized 1 hour after EdU injection.
Result:Showed a dose-dependent decrease in caspase 3/7 activation.Attenuated chemotherapy-induced myelosuppression in mice.

体外研究:
Trilaciclib (10-1000 nM; 24 h) 可逆地调节小鼠和犬骨髓造血干细胞和祖细胞的增殖。Trilaciclib (10-1000 nM; 24 h) 可将 CDK4/6 依赖性细胞的细胞周期阻滞在 G1 期,对HS68的EC50为 30 nM。Trilaciclib (300 nM;16 或 48 h) 可保护 CDK4/6 依赖性细胞(HS68、WM2664)免受化疗引起的损伤,并减弱化疗引起的细胞凋亡。
