  Synthesis and SAR studies of 5-(pyridin-4-yl)-1,3,4-thiadiazol-2-amine derivatives as potent inhibitors of Bloom helicase

  摘要：

  Human cells utilize a variety of complex DNA repair mechanisms in order to combat constant mutagenic and cytotoxic threats from both exogenous and endogenous sources. The RecQ family of DNA helicases, which includes Bloom helicase (BLM), plays an important function in DNA repair by unwinding complementary strands of duplex DNA as well as atypical DNA structures such as Holliday junctions. Mutations of the BLM gene can result in Bloom syndrome, an autosomal recessive disorder associated with cancer predisposition. BLM-deficient cells exhibit increased sensitivity to DNA damaging agents indicating that a selective BLM inhibitor could be useful in potentiating the anticancer activity of these agents. In this work, we describe the medicinal chemistry optimization of the hit molecule following a quantitative high-throughput screen of >355,000 compounds. These efforts lead to the identification of ML216 and related analogs, which possess potent BLM inhibition and exhibit selectivity over related helicases. Moreover, these compounds demonstrated cellular activity by inducing sister chromatid exchanges, a hallmark of Bloom syndrome. Published by Elsevier Ltd.

  We previously reported diarylurea derivatives as cannabinoid type-1 receptor (CB1) allosteric modulators, which were effective in attenuating cocaine-seeking behavior. Herein, we extended the structure-activity relationships of PSNCBAM-1 (2) at the central phenyl ring directly connected to the urea moiety. Replacement with a thiophene ring led to 11 with improved or comparable potencies in calcium

  我们先前曾报道过二芳基脲衍生物是大麻素1型受体（CB1）变构调节剂，可有效减弱可卡因的寻找行为。在这里，我们扩展了PSNCBAM-1（2）在直接连接到脲部分的中心苯环上的构效关系。噻吩环取代导致11在钙动员，[35S]GTPγS结合和cAMP分析方面具有改进或相当的效力，而非芳香环取代则导致调节活性显着降低。这些化合物在[35S]GTPγS结合中没有反向激动作用，这一特征通常被认为会导致不良的精神病学效应。尽管11在大鼠肝微粒体中具有良好的代谢稳定性，但显示出适度的溶解度和血脑屏障通透性。
