  Potent and Selective Inhibitors of MTH1 Probe Its Role in Cancer Cell Survival

  摘要：

  Recent literature has claimed that inhibition of the enzyme MTH1 can eradicate cancer. MTH1 is one of the "housekeeping" enzymes that are responsible for hydrolyzing damaged nucleotides in cells and thus prevent them from being incorporated into DNA. We have developed orthogonal and chemically distinct tool compounds to those published in the literature to allow us to test the hypothesis that inhibition of MTH1 has wide applicability in the treatment of cancer. Here we present the work that led to the discovery of three structurally different series of MTH1 inhibitors with excellent potency, selectivity, and proven target engagement in cells. None of these compounds elicited the reported cellular phenotype, and additional siRNA and CRISPR experiments further support these observations. Critically, the difference between the responses of our highly selective inhibitors and published tool compounds suggests that the effect reported for the latter may be due to off-target cytotoxic effects. As a result, we conclude that the role of MTH1 in carcinogenesis and utility of its inhibition is yet to be established.

  their potent antitubercular activity at sub‐microgram per mL concentrations against both sensitive and multidrug‐resistant (MDR) Mycobacterium tuberculosis strains. Six out of the top nine MIC‐ranked candidates were found to inhibit mycobacterial ATP synthesis activity with IC50 values between 20 and 40 μm, one had IC50>66 μm, and two showed no inhibition, despite their antitubercular activity. These results

  Bedaquiline（BDQ）是一种新型的高效抗结核药物，已于2013年获得美国FDA批准。由于立体结构的复杂性，化学合成和化合物优化非常困难且昂贵。这项研究描述了苯达喹啉的结构简化，同时保留了抗结核活性。该化合物的结构被分为多个片段，并以各种组合重新组装，同时用非手性键取代了两个手性碳原子。设计了四个系列的类似物。这些候选药物对敏感和耐多药（MDR）结核分枝杆菌均保持其有效的抗结核活性，浓度为每微克每毫升。株。六出前的被发现有9 MIC-排名候选抑制分枝杆菌ATP合成与IC活性50 20和40μ之间的值米，一个有IC 50 > 66μ米，和两个显示无抑制，尽管它们抗结核活性。这些结果为开发化学上不太复杂，成本更低的苯达喹啉衍生物提供了基础，并描述了对非ATP合酶相关靶标具有抗结核活性的两种衍生物的鉴定。
