生物活性:
Anticancer agent 98 (compound 12k) is a microtubule/tubulin-polymerization inhibitor (Kd=16.9 μM). Anticancer agent 98 exerts antiproliferative potency against tumor cells, exhibits anti-angiogenesis effect in vitro. Anticancer agent 98 exhibits good human and mouse liver microsomes stability with both t1/2>300 min.

体内研究:
Anticancer agent 98 (2.5 mg/kg;静脉注射;每周两次,持续 2 周) 耐受性良好,在雄性 NSG 小鼠的 PC3/TxR 异种移植肿瘤中没有显着的体重减轻。相对于 Paclitaxel (HY-B0015;10 mg/kg,每周一次) 和对照组,Anticancer agent 98 还显着减缓了前列腺癌肿瘤的进展。NSG 小鼠中的药代动力学分析RouteDose (mg/kg)Cmax (ng/mL)tmax (min)AUC (ng·min/mL)t1/2 (min)F (%)
