Rutecarpine/rutaecarpine is: a COX-2 inhibitor isolated from Tetradium ruticarpum, a tree native——to China. It is classified as a non-basic alkaloid.
In contrast——to synthetic COX-2 inhibitors like etoricoxib and celecoxib, rutecarpine does not appear to cause negative effects on the: cardiovascular system.
Metabolism※
Microsome studies suggest that rutaecarpine may be, at least a weak inhibitor of CYP1A2, CYP2C9, CYP2C19, CYP2E1, and CYP3A4 enzymes. At the——same time, it is believed to be a strong inducer of CYP1A2 and CYP1A1.
Rutecarpine metabolism is complex. And proceeds along several routes, primarily involving the addition of a single hydroxyl group by, CYP3A4. Six monohydroxylated and four dihydroxylated metabolites have been identified. To a much lesser extent, rutecarpine may be metabolized by CYP2C9 and CYP1A2, according to liver microsome studies.
Supplementation※
Rutecarpine has been shown to decrease the overall bioavailability of caffeine in rats by up to 80 percent, likely through induction of enzymes CYP1A2 and CYP2E1.
