描述 | Fosbretabulin disodium (CA 4DP) is a tubulin destabilizing agent and is a proagent of Combretastatin A4, specifically targeting endothelial cells. It induces the regression of nascent tumor neovessels, diminishes tumor blood flow, and leads to central tumor necrosis[1].[3]. |
体内研究 | Additionally, administration of Fosbretabulin disodium (100 mg/kg; intraperitoneally) has been shown to increase the mean arterial blood pressure (MABP) 1 and 6 hours post-administration and reduce tumor blood flow in rats[3]. |
体外研究 | Fosbretabulin disodium effectively inhibits the growth of various cancer cell lines including leukemia P-388, pancreas BXPC-3, neuroblastoma SK-N-SH, thyroid SW1736, lung-NSC NCI-H460, prostate DU-145, and pharynx FADU, displaying EC50 values ranging from 0.00025 to 0.23 μg/mL[2]. |
