Tubulin binding agents (TBAs) are drugs commonly used in cancer therapy as antimitotics. In the last years it has been described that TBAs, like combretastatin A-4 (CA-4), present also vascular disrupting activity and among its derivatives we identified three analogues endowed with potent microtubule depolymerizing activity, higher than that of the lead compound. In this paper we have investigated...
TR-644 is a novel combretastatin A-4 (CA-4) analogue endowed with potent microtubule depolymerizing activity superior to that of the lead compound and it also has high affinity to colchicines binding site of tubulin. We tested TR-644 anti-angiogenic effects in human umbilical endothelial cells (HUVEC). It showed no significant effects on the growth of HUVEC cells at concentrations below 1,000 nM,...
