Bioactivity | Selinexor (KPT-330), analog of KPT-185, is an orally bioavailable and selective CRM1 inhibitor[1][2]. | ||||||||||||
Target | CRM1 | ||||||||||||
Invitro | 作为 KPT-185 的临床候选类似物,KPT-330 对 T-ALL 细胞的活力表现出相似的作用,并引发快速的细胞凋亡反应。KPT-330 还减少 MOLT-4、Jurkat、HBP-ALL、KOPTK-1、SKW-3 和 DND-41 细胞系的细胞生长,IC50 值为 34-203 nM[1]。 | ||||||||||||
In Vivo | Selinexor (KPT-330) 在体内显著抑制 T-ALL 细胞 (MOLT-4) 和 AML 细胞 (MV4-11) 的生长,对正常造血细胞几乎没有毒性[1]。 在具有弥漫性人类 MM 骨损伤的 SCID 小鼠中,KPT-330 抑制 MM 诱导的骨溶解并延长存活期。此外,KPT-330 通过阻断 RANKL 诱导的 NF-κB 和 NFATc1 直接损害破骨细胞生成和骨吸收,对成骨细胞和 BMSCs 的影响最小[2]。 | ||||||||||||
