WebApr 1, 2024 · Cryptophycins are potent tubulin polymerization inhibitors with picomolar antiproliferative potency in vitro and activity against multidrug-resistant (MDR) cancer cells. Because of neurotoxic side effects and limited efficacy in vivo, cryptophycin-52 failed as a clinical candidate in cancer treatment. WebCryptophycin-52 (Cp-52) is potentially the most potent anticancer drug known, with IC 50 values in the low picomolar range, but its binding site on tubulin and mechanism of action are unknown.
