General description

(S,R)-Noscapine is a phthalideisoquinoline alkaloid found in opium. It is an antimicrotubule agent that also shows potent antitumor activity.

Application

Noscapine may be used as a source to synthesize its bromo-derivatives, which has higher tubulin binding activity when compared to noscapine. Its 3,4,5-trimethoxybenzyl analog is a potential antitumor agent.

Noscapine, a common oral antitussive agent, has been shown to have potent antitumor activity in a variety of cancers. Treatment of glioblastoma multiforme (GBM) with temozolomide (TMZ), its current standard of care, is problematic because the tumor generally recurs and

Noscapine biosynthesis in opium poppy is thought to occur via N-methylcanadine, which would be produced through 9-O-methylation of (S)-scoulerine, methylenedioxy bridge formation on (S)-tetrahydrocolumbamine, and N-methylation of (S)-canadine. Only scoulerine 9-O-methyltransferase has been functionally characterized. We report the isolation and

We have previously shown that a novel microtubule-modulating noscapinoid, EM011 (9-Br-Nos), displays potent anticancer activity by inhibition of cellular proliferation and induction of apoptosis in prostate cancer cells and preclinical mice models. However, physicochemical and cellular barriers encumber the development
