NCIt definition : A phthalide isoquinoline non-narcotic alkaloid derived from the opium poppy Papaver
somniferum, with mild analgesic, antitussive, and potential antineoplastic activities.
Noscapine exerts its antitussive effects through the activation of sigma opioid receptors.
This agent appears to exert its antimitotic effect by binding to tubulin, resulting
in a disruption of microtubule assembly dynamics and subsequently, the inhibition
of mitosis and tumor cell death.;
