The present invention relates to the discovery of novel compounds that can be used to treat and/or prevent heart failure in a subject. In certain embodiments, the compounds of the invention are sulfide: quinone oxidoreductase (SQOR) inhibitors. In other embodiments, the compounds of the invention increase physiological levels of H2S in the subject. In yet other embodiments, administration of the compounds of the invention treats and/or prevents hypertension, and/or atherosclerosis, and/or pathological cardiac remodeling that leads to heart failure in the subject.

first small-molecule inhibitors of human sulfide:quinone oxidoreductase (SQOR) that decrease the rate of breakdown of hydrogen sulfide (H2S), a potent cardioprotective signaling molecule. SQOR is a mitochondrial membrane-bound protein that catalyzes a two-electron oxidation of H2S to sulfane sulfur (S0), using glutathione (or sulfite) and coenzymeQ (CoQ) as S0 and electron acceptor, respectively.
在这里,我们报告了人类硫化物的第一个小分子抑制剂:醌氧化还原酶 (SQOR) 可降低硫化氢 (H 2 S) 的分解速率,硫化氢是一种有效的心脏保护信号分子。SQOR 是一种线粒体膜结合蛋白,使用谷胱甘肽(或亚硫酸盐)和辅酶 Q (CoQ) 作为 S 0 ,催化 H 2 S 到硫烷硫 (S 0 )的双电子氧化和电子受体,分别。抑制 SQOR 可能构成治疗射血分数降低的心力衰竭的新方法。从高通量筛选中确定的热门开始,我们通过将主要候选者对接到我们的 SQOR 晶体结构来指导 SAR 开发。我们鉴定了有效的 SQOR 抑制剂,例如19,它具有 29 nM 的 IC 50抑制 SQOR 和体内功效测试所需的有利药代动力学和 ADME 特性。
