bedaquiline where the phenyl B-unit was replaced with monocyclic heterocycles of widely differing lipophilicity (thiophenes, furans, pyridines) were synthesised and evaluated. While there was an expected broad positive correlation between lipophilicity and anti-TB activity, the 4-pyridyl derivatives appeared to have an additional contribution to antibacterial potency. The majority of the compounds were (desirably)
合成并评估了苯达喹啉的类似物,其中苯B单元被亲脂性差异很大的单环杂环(噻吩,呋喃,吡啶)取代。虽然亲脂性和抗结核活性之间存在广泛的正相关关系,但4-吡啶基衍生物似乎对抗菌效力具有额外的贡献。与贝达喹啉相比,大多数化合物的极性更大(清除率更高),清除率更高,并显示出可接受的口服生物利用度,但其hERG耐受性的改善有限(且无法预测)。
