  Structure activity relationships, multidrug resistance reversal and selectivity of heteroarylphenyl ABCG2 inhibitors

  摘要：

  An overexpression of the transmembrane ATP-binding cassette transporter G2 (ABCG2, BCRP) in cancer tissues is supposed to play a role in the multidrug resistance (MDR) of tumors resulting in an inefficient chemotherapy. Therefore, co-administration of selective and non-toxic ABCG2 inhibitors is a promising strategy for improving the efficacy of chemotherapy by blocking ABCG2-mediated export of the cytostatic drugs. In the present study, we designed a small library of 38 novel compounds containing a heteroaryl-phenyl scaffold possessing several (bioisosteric) moieties, and twelve new precursors. We investigated the library for ABCG2 inhibition, for the selectivity against MDR-involved efflux pump ABCBI (P-gp) and for toxicity. Structure activity relationship (SAR) studies revealed that, at least a phenylheteroaryl-phenylamide scaffold is necessary for observing an ABCG2 inhibition. 4-Methoxy-N-(2(2-(6-methoxypyridin-3-yl)-2H-tetrazol-5-yl)phenyl)benzamide (43) exhibited a high potency (IC50 = 61 nM)), selectivity, low intrinsic toxicity and reversed the ABCG2-mediated drug resistance in presence of only 0.1 mu M.

  The development of a highly efficient and practical protocol for the direct CN coupling of H‐tetrazole and boronic acid was presented. A careful and patient optimization of a variety of reaction parameters revealed that this conventionally challenge reaction could indeed proceed efficiently in a very simple system, that is, just by stirring the tetrazoles and boronic acids under oxygen in the presence

  提出了一种高效，实用的方案，用于将H-四唑与硼酸直接进行CN偶联。对各种反应参数的仔细和耐心的优化显示，这种常规的挑战性反应确实可以在非常简单的系统中高效地进行，也就是说，只需在存在不同的Cu I或Cu II的情况下在氧气下搅拌四唑和硼酸即可。在100°C的DMSO中仅负载5 mol％的盐。最重要的是，该反应可以以区域特异性方式非常顺利地进行，从而以高到极好的收率得到2,5-二取代的四唑。一项机理研究表明，四唑和DMSO分别对反应过程中的催化活性铜和溶剂起着至关重要的作用。结果表明，在反应循环中，Cu I催化剂可以通过氧化铜的胺化反应被氧气氧化为Cu II，形成[CuT 2 D]络合物（T =四唑阴离子； D = DMSO）。由此形成的Cu II络合物被证实是真正的催化活性铜物质。即铜II复杂歧化至芳基的Cu III和Cu我在硼酸的存在下进行。轻松消除Cu III物种可提供CN耦合产物。本文介绍的结果不仅为合成2
