Fosbretabulin (Combretastatin A4 Phosphate (CA4P)) Disodium是微管去稳定药物,是combretasain A4(CA4)的水溶性前体药物和肿瘤血管靶向剂。
微管是圆柱形和丝状结构,对于维持细胞形状、迁移、纤毛和鞭毛流动性等是必须的,微管蛋白是微管的主要组成部分。
在增殖的内皮细胞中,CA4P(剂量小于最大耐受剂量的1/10)导致肿瘤血管关闭,缩短CA4P的药物暴露时间,引起长期的抗增殖效果和细胞毒性效应[1]。在CA40处理的内皮细胞中,肌球蛋白轻链磷酸化,导致肌球蛋白收缩,肌动蛋白应力纤维的组装和粘着斑的形成[2]。在HUVEC细胞中,CA4P阻断生长因子诱导的内皮细胞增殖和迁移,损坏毛细管的形成[3]。
在C57BL / 6小鼠中,CA4P与抗VE-cardherinm的Ab联合使用可促进B16黑色素肿瘤坏死,抑制肿瘤血管生成[3]。在人乳腺癌模型中,使用CA4P 6小时后,功能性血管体积减少93%,该效应继续持续了12小时[1]。
