7-O-Demethyl α-Narcotine, is a derivative of Narcotine (N378890), a noscapinoid class of microtubule binding compounds that alter microtubule dynamics without affecting tubulin polymer mass. Noscapinoids show great promise as chemotherapeutic agents for the treatment of human cancers. Unlike Narcotine, (-)-α-Narcotinediol deos not inhibit small-intestinal transport in rats.
