WebCryptophycins are a class of 16-membered highly cytotoxic macrocyclic depsipeptides isolated from cyanobacteria. The biological activity is based on their ability to interact with tubulin. They interfere with microtubule dynamics and prevent microtubules from forming correct mitotic spindles, which causes cell-cycle arrest and apoptosis. WebCryptophycin 1 is one of the most potent tubulin-destabilizing agents ever discovered, resulting in cellular arrest at the G2/M phase via hyperphosphorylation of Bcl-2, thereby …
