P-glycoprotein (P-gp, MDR1) is a membrane transporter expressed in several regions of our body. It plays a crucial defense role as it mediates the efflux of hundreds of potentially toxic substances. However, P-gp is one of the main causes of failure in cancer chemotherapy, as a number of chemotherapeutic agents are P-gp substrates. Another interesting implication concerns the correlation between P-gp expression impairment and the onset of several central nervous system pathologies such as Alzheimer's and Parkinson's diseases. In view of these considerations, in the present study, a new series of P-gp modulators have been designed, synthesized and evaluated for their activity towards P-gp and two other sister proteins (BCRP and MRP1). The compounds, structurally correlated to the potent but non-selective P-gp inhibitor MC70 [4′-(6,7-dimethoxy-3,4-dihydro-1H-isoquinolin-2-ylmethyl)biphenyl-4-ol], proved fairly selective towards P-gp, with a potency in the micromolar range. Compounds 5a, 5d and 12d proved capable of restoring doxorubicin toxicity in resistant cancer cells.

新的基于四氢异喹啉的P-糖蛋白调节剂:联苯核心的修饰产生选择性配体

P-糖蛋白(P-gp,MDR1)是在我们身体的多个区域表达的膜转运蛋白。它起着至关重要的防御作用,因为它介导了数百种潜在有毒物质的外排。但是,P-gp是癌症化疗失败的主要原因之一,因为许多化学治疗剂都是P-gp底物。另一个有趣的含义涉及P-gp表达障碍与多种中枢神经系统疾病(例如阿尔茨海默氏病和帕金森氏病)的发作之间的相关性。考虑到这些考虑因素,在本研究中,已经设计,合成和评估了一系列新的P-gp调节剂对P-gp和另外两个姊妹蛋白(BCRP和MRP1)的活性。这些化合物[4'-(6,7-二甲氧基-3,4-二氢-1 H-异喹啉-2-基甲基)联苯-4-醇]被证明对P-gp具有相当的选择性,其效力在微摩尔范围内。证明化合物5a5d12d能够恢复抗性癌细胞中的阿霉素毒性。
