Tariquidar is a P-glycoprotein inhibitor undergoing research as an adjuvant against multidrug resistance in cancer. Tariquidar non-competitively binds to the p-glycoprotein transporter, thereby inhibiting transmembrane transport of anticancer drugs.
Jatrophane 5 demonstrates the most powerful inhibition of P-gp, higher than R(+)-verapamil and tariquidar in colorectal multi-drug resistant (MDR) cells (DLD1-TxR).
2,5,7,8,9,14-Hexaacetoxy-3-benzoyloxy-15-hydroxyjatropha-6(17),11E-diene (Jatrophane 2 ) exhibits significant antifeedant activity against a generalist plant-feeding insect, the cotton bollworm (Helicoverpa armigera). Jatrophane 2 also demonstrates the mo
