rendered ineffective, increasing the demand for novel antibiotics with low potential for resistance. Here we report the synthesis of 18 novel cationic tetrahydroisoquinoline-triazole compounds. Five of the developed molecules were active against S. aureus at a low MIC of 2–4 μg/mL. Hit compound 4b was also found to eliminate M. tuberculosis H37Rv at MIC of 6 μg/mL. This potent molecule was found to eliminate
抗生素耐药性是现代医学面临的最大威胁之一。曾经常规用于治疗感染的药物正在变得无效,从而增加了对具有低耐药性的新型抗生素的需求。在这里,我们报告了 18 种新型阳离子四氢异喹啉-三唑化合物的合成。五种开发的分子在 2-4 μg/mL 的低 MIC 下对金黄色葡萄球菌具有活性。还发现命中化合物4b在 6 μg/mL 的 MIC 下消除结核分枝杆菌H37Rv。发现这种强效分子可有效消除金黄色葡萄球菌,连续传代 30 天后未观察到耐药性。这些结果确定了化合物4b及其类似物作为进一步药物开发的潜在候选者,有助于应对抗生素耐药性的威胁。

Capsazepine as well as its derivatives and analogues are general inhibitors of constriction of human small airways. From a systematic variation of the capsazepine structure, divided into four regions, SARs were established. This part concerns the catechol moiety of the A-ring as well as the 2,3,4,5-tetrahydro-1H-2-azepine moiety (the B-ring) of capsazepine. It is revealed that a conformational constrain (as a fused ring) is important and that compounds with a six-membered B-ring (as a 1,2,3,4-tetrahydroisoquinoline) in general are more potent than the corresponding isoindoline, 2,3,4,5 -tetrahydro-1H-2-benzazepi ne and 2,3,4,5-tetrahydro-1H-3-benzazepine derivatives.
