Product Information
| Description: | YS-370 (compound 44) is a potent, high selective, and orally active inhibitor of P-glycoprotein (P-gp). YS-370 stimulates the P-gp ATPase activity and has moderate inhibition against CYP3A4. YS-370 effectively reverses multidrug resistance (MDR) to paclitaxel and colchicine in SW620/AD300 and HEK293T-ABCB1 cells. YS-370 in combination with paclitaxel achieves much stronger antitumor activity. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
