生物活性:
Tubulin polymerization-IN-41 is a potent tubulin polymerization inhibitor with the IC50 of 2.61 μM. Tubulin polymerization-IN-41 targets the Colchicine-binding site of tubulin. Tubulin polymerization-IN-41 has anticancer effects.

体内研究:
Tubulin polymerization-IN-41(compound C3;5-20 mg/kg;i.p;每两天一次;连续 21 天)在药物处理期间表现出显着的剂量依赖性肿瘤生长抑制效力,且体重没有减轻。Animal Model:Five-week-old female athymic nude mice injected with MCF-7 cells
Dosage:5, 10, and 20 mg/kg
Administration:Intraperitoneal injection; every two days; for 21 consecutive days
Result:Exhibited the significant potency of tumor growth inhibition in a dose dependence without weight loss in the drug-treated period.

体外研究:
Tubulin polymerization-IN-41 (compound C3) 表现出显着的抗增殖活性,对 K562、MCF-7、HT29 和 HCT116 细胞的 IC50 值分别为 6.3 nM、9.2 nM、8.3 nM 和 8.7 nM。此外,Tubulin polymerization-IN-41 对紫杉醇耐药的 MCF-7 细胞和 A549 细胞显示出显着的活性。Tubulin polymerization-IN-41(compoundC3;5-20 nM)以浓度依赖方式下调乙酰-α-微管蛋白(Ac-α-微管蛋白)的表达并上调脱酪氨酸-α-微管蛋白(DeY-α-微管蛋白)的表达。Tubulin polymerization-IN-41 (compound C3; 5-20 nM; 24 h) 可将癌细胞阻滞在 G2/M ,并呈浓度依赖性诱导 MCF-7 细胞凋亡。Tubulin polymerization-IN-41(compound C3;5-20 nM;24 小时)减少 Ser216 磷酸化,导致 cdc2 Tyr15 去磷酸化和 Thr161 磷酸化,最终导致后续 cdc2/cyclin B1 复合物的激活。MCF-7 cells5 nM, 10 nM, 20 nM24 hMCF-7 cells5 nM, 10 nM, 20 nM24 h
