What is Cryptophycin?

Plain description, key identifiers and synonyms

Cryptophycin is the cryptophycins are a family of 16-membered macrolide antimitotic agents isolated from the cyanobacteria Nostoc sp. The mechanism of anticancer activity of the cryptophycins has been associated with their destabilization of microtubules and induction of bcl-2 phosphorylation leading to apoptosis. Cryptophycins demonstrated activity against the wide spectrum of solid tumors including those that overexpress the multidrug resistance efflux pump P-glycoprotein. (NCI)
