Taxinine and taxinine B can inhibit the drug transport by P-glycoprotein in multidrug-resistant cells. Taxinine B shows stronger inhibitory effects than acetylsalicylic acid (ASA) on platelet aggregation induced by arachidonic acid (AA).
2-Deacetoxytaxinine J shows significant in vitro activity against breast cancer cell line at a concentration of 20 microM and 10 microM in MCF-7 and MDA-MB-231 respectively.
2-Deacetoxytaxinine B is a strongly inhibitor against U46619-induced aggregation, it shows strong inhibitory effects against arachidonic acid (AA)-induced aggregation.
