Cryptophycin - an overview ScienceDirect Topics

WebCryptophycin 1 is a natural product that was initially isolated from blue-green algae which has shown potent broad spectrum antitumor activity in preclinical in vitro and in vivo models. The drug strongly binds to tubulin and disrupts microtubule assembly for more than 24 hours after its removal. WebCryptophycin is a class of cyclic depsipeptides that was originally isolated from the cyanobacteria Nostoc sp. (Figure 1, right) in 1990 by researchers at Merck as a potent fungicide, however, the compound was found to be highly toxic to be developed as antifungal. Some years later, crypthophycins were discovered to be potent cytotoxins. Cryptophycins are a family of macrolide molecules that are potent cytotoxins and have been studied for potential antiproliferative properties useful in developing chemotherapy. They are members of the depsipeptide family. See more Cryptophycins were originally discovered in 1990 in cyanobacteria of the genus Nostoc. Cryptophycins were patented as antifungal agents with an unknown mechanism of action and subsequently identified as See more Cryptophycins are potent microtubule inhibitors, with a mechanism of action similar to that of vinca alkaloids. Treatment of cells … See more Cryptophycins were first isolated from cyanobacteria but have subsequently been produced by chemical synthesis. Chemoenzymatic syntheses have also been reported.
