Abstract:
Compounds, pharmaceutical compositions including the compounds, and methods of preparation and use thereof are disclosed. The compounds are noscapine analogs. The compounds and compositions can be used to treat and/or prevent a wide variety of cancers, including drug resistant cancers. While the antitussive plant alkaloid, noscapine, binds tubulin, displays anticancer activity, and has a safe pharmacological profile in humans, structure-function analyses pointed to a proton at position 9 of the isoquinoline ring that can be modified without compromising tubulin binding activity. Noscapine analogs with various functional moieties at position 9 on the isoquinoline ring kill human cancer cells resistant to other anti-microtubule agents, such as vincas and taxanes.
