Noscapine analogs and their use in treating cancers, including drug-resistant cancers

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. Representative analogs include the 9-nitro, 9-bromo-, 9-iodo-, and 9-fluoro-noscapines, which bind tubulin and induce apoptosis selectively in tumor cells (ovarian and T-cell lymphoma) resistant to paclitaxel, vinblastine and teniposide. Surprisingly, treatment with one of the analogs, 9-nitro-nos, at doses as high as 100 μM, did not affect the cell cycle profile of normal human fibroblasts. This selectivity for cancer cells represents a unique edge over the other available antimitotics. The compounds can perturb the progression of cell cycle by mitotic arrest, followed by apoptotic cell death associated with increased caspase-3 activation and appearance of TUNEL-positive cells. Thus, the compounds are novel therapeutic agents for a variety of cancers, including ovarian and T-cell lymphoma cancers, even those that have become drug-resistant to currently available chemotherapeutic drugs.
