  Optimization of Propafenone Analogues as Antimalarial Leads

  摘要：

  Propafenone, a class Ic antiarrythmic drug, inhibits growth of cultured Plasmodium falciparum. While the drug's potency is significant, further development of propafenone as an antimalarial would require divorcing the antimalarial and cardiac activities as well as improving the pharmacokinetic profile of the drug. A small array of propafenone analogues was designed and synthesized to address the cardiac ion channel and PK liabilities. Testing of this array revealed potent inhibitors of the 3D7 (drug sensitive) and K1 (drug resistant) strains of P. falciparum that possessed significantly reduced ion channel effects and improved metabolic stability. Propafenone analogues are unusual among antimalarial leads in that they are more potent against the multidrug resistant K1 strain of P. falciparum compared to the 3D7 strain.

  structure–activity relationship analysis, and docking studies to investigate the role of hydrogen bond (H‐bond) donor/acceptor properties in transporter–ligand interaction. In a previous work, it has been shown that propafenone analogs with a 4‐hydroxy‐4‐piperidine moiety exhibit a generally 10‐fold higher P‐gp inhibitory activity than expected based on their lipophilicity. Here, we specifically expanded the data

  P-糖蛋白 (P-gp) 是一种依赖 ATP 的外排泵，对治疗药物的吸收、分布和排泄具有显着影响。由于 P-gp 抑制可导致药物-药物相互作用和改变药物生物利用度，因此识别与抑制相关的分子特性在药物开发中具有重要意义。在这项研究中，我们结合化学合成、体外测试、定量构效关系分析和对接研究来研究氢键 (H-bond) 供体/受体特性在转运蛋白-配体相互作用中的作用。在之前的工作中，已经表明具有 4-羟基-4-哌啶部分的普罗帕酮类似物的 P-gp 抑制活性通常比基于其亲脂性预期的高 10 倍。这里，我们通过在 4-苯基哌啶部分的第 4 位引入取代基来扩展数据集，以评估 H 键供体/受体特征在该区域的重要性。结果表明，确实有一个氢键受体，如羟基和甲氧基，通过与 Tyr310 形成氢键来增加亲和力。

  determinants of propafenone derivatives that enable drug dissociation from the closed channel state. Propafenone and four derivatives with 'short' side chains were trapped in the closed channel. Five out of six bulky derivatives efficiently dissociated from the channel at rest. One propafenone derivative with a similar bulk but lacking an H-bond acceptor in this region was trapped. Correlations were
