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 B is a strongly inhibitor against U46619-induced aggregation, it shows strong inhibitory effects against arachidonic acid (AA)-induced aggregation.
