Noscapine analogs and their use in treating 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 analyzes 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.
1. A method of treating lung cancer comprising administering an effective amount of ((S)-6,7-dimethoxy-3-((R)-4-methoxy-6-methyl-9-bromo-5,6,7,8-tetrahydro-[1,3]dioxolo[4,5-g]isoquinolin-5-yl)isobenzofuran-1(3H)-one) or pharmaceutically acceptable salts thereof to a patient in need of treatment thereof.
2. The method of claim 1 , wherein ((S)-6,7-dimethoxy-3-((R)-4-methoxy-6-methyl-9-bromo-5,6,7,8-tetrahydro-[1,3]dioxolo[4,5-g]isoquinolin-5-yl)isobenzofuran-1(3H)-one) or pharmaceutically acceptable salts thereof are administered orally.
3. The method of claim 1 , wherein ((S)-6,7-dimethoxy-3-((R)-4-methoxy-6-methyl-9-bromo-5,6,7,8-tetrahydro-[1,3]dioxolo[4,5-g]isoquinolin-5-yl)isobenzofuran-1(3H)-one) or pharmaceutically acceptable salts thereof is administered in combination with at least one other anticancer agent.
4. The method of claim 3 , wherein the other anticancer agent is selected from busulfan, cis-platin, mitomycin C, and carboplatin.
5. The method of claim 3 , wherein the other anticancer agent is selected from colchicine, vinblastine, paclitaxel, and docetaxel.
6. The method of claim 3 , wherein the other anticancer agent is selected from doxorubicin and etoposide.
