Abstract

P-glycoprotein transporter (P-gp, ABCB1) is a major contributor to multidrug resistance, making it a valuable target for the development of novel P-gp inhibitor to overcome multidrug resistance. In this study, forty-nine novel seco-DSPs and seco-DMDCK derivatives were synthesized and evaluated their chemo-sensitize abilities to paclitaxel in A2780/T cell lines. Most of them exhibited a comparable reversal multidrug-resistance activity than verapamil. Especially, compound 27f showed a remarkable chemo-sensitization with more than 425-fold reversal ratio in A2780/T cells. The study of preliminary pharmacological mechanism displayed that compound 27f was more effective to increase the accumulation of paclitaxel and Rhodamine 123 than verapamil via inhibiting P-gp for reversing multidrug-resistance. In addition, a higher than 40 μM IC50 values of hERG Potassium Channel inhibition concentration suggested that compound 27f hardly had relevant cardiac toxicity. These results indicated that compound 27f might be a potential candidate to further investigate for the development of chemosensitizer with MDR reversal activity.
