  Quinolinyl Pyrimidines: Potent Inhibitors of NDH-2 as a Novel Class of Anti-TB Agents

  摘要：

  NDH-2 is an essential respiratory enzyme in Mycobacterium tuberculosis (Mtb), which plays an important role in the physiology of Mtb. Herein, we present a target-based effort to identify a new structural class of inhibitors for NDH-2. High-throughput screening of the AstraZeneca corporate collection resulted in the identification of quinolinyl pyrimidines as the most promising class of NDH-2 inhibitors. Structure-activity relationship studies showed improved enzyme inhibition (IC50) against the NDH-2 target, which in turn translated into cellular activity against Mtb. Thus, the compounds in this class show a good correlation between enzyme inhibition and cellular potency. Furthermore, early ADME profiling of the best compounds showed promising results and highlighted the quinolinyl pyrimidine class as a potential lead for further development.

  Type II NADH dehydrogenase (NDH-2) is an essential component of electron transfer in many microbial pathogens but has remained largely unexplored as a potential drug target. Previously, quinolinyl pyrimidines were shown to inhibit Mycobacterium tuberculosis NDH-2, as well as the growth of the bacteria [Shirude, P. S.; ACS Med. Chem. Lett. 2012, 3, 736−740]. Here, we synthesized a number of novel quinolinyl

  II 型 NADH 脱氢酶 (NDH-2) 是许多微生物病原体中电子转移的重要组成部分，但作为潜在的药物靶点仍未被广泛探索。以前，喹啉基嘧啶被证明可以抑制结核分枝杆菌NDH-2，以及细菌的生长 [施鲁德，PS; ACS医学。化学。莱特。 2012 年，第 3期，第 736-740 页]。在这里，我们合成了许多新型喹啉基嘧啶并研究了它们的性质。在抑制来自结核分枝杆菌和耻垢分枝杆菌的 NDH-2 酶方面，最好的化合物与先前报道的同类抑制剂具有相似的效力（半最大抑制浓度（IC 50）在低微米范围内的值）。然而，许多化合物对革兰氏阴性病原体具有更好的活性，最低抑菌浓度 (MIC) 低至 2 μg/mL。多变量分析（偏最小二乘法 (PLS) 和主成分分析 (PCA)）表明，总体配体电荷是决定抗菌活性的最重要因素之一，其模式因特定细菌种类而异。在某些情况下（例如，分枝杆菌），IC 50之间存在明显的相关性值和观察到的
