3‐triazole‐tethered isatin–coumarin hybrids 7a–l integrate three anti‐tuberculosis bioactive substances/pharmacophoric units including coumarin, isatin, and I‐A09 were designed, synthesized, and tested for their in vitroanti‐mycobacterial activity against Mycobacterium smegmatis and Mycobacterium tuberculosis H37Rv as well as cytotoxicity in VERO cell line. The results showed that all hybrids exhibited weak to moderate
设计,合成并测试了一系列新颖的1 H -1,2,3-三唑系留的靛红-香豆素杂合体7a - l,其中包括香豆素,靛红和I - A09这三种抗结核生物活性物质/药效单元。它们对耻垢分枝杆菌和结核分枝杆菌H37Rv的体外抗分枝杆菌活性以及对VERO细胞系的细胞毒性。结果表明,所有杂种均表现出对测试的两种菌株弱至中等的活性,最小抑菌浓度范围为50至200μg/ mL。

isatin‐(thio)semicarbazide/oxime‐1H‐1,2,3‐triazole‐coumarin hybrids 8a–l were designed, synthesized, and evaluated for their in vitroanti‐mycobacterial activities against M. tuberculosis (MTB) H37Rv and MDR‐TB. The results showed that all the hybrids (MIC: 50–>200 μg/mL) exhibited weak to moderate inhibitory activity against MTB H37Rv and MDR‐TB, which were far less potent than the references isoniazid (MIC: 0.05 μg/mL)
具有潜在抗结核活性的Isatin和香豆素衍生物,而(thio)semicarbazide /肟和1 H 1,2,3-三唑部分具有良好的特性,例如氢键和/或金属螯合能力,因此这四个药效基团的整合一个分子可以提供更有效的抗结核候选药物。基于先前的考虑,设计,合成并评估了12种Isatin-(thio)semicarbazide / oxime-1 H -1,2,3 -triazole-coumarin杂种8a-1,并评估了它们对M的体外抗分枝杆菌活性。肺结核H 37Rv和MDR-TB。结果表明,所有杂种(MIC:50–> 200μg/ mL)对MTB H 37 Rv和MDR-TB的抑制作用均弱至中度,远不如参考异烟肼(MIC:0.05μg/ mL)强)和利福平(MIC:0.39μg/ mL)对抗MTB H 37 Rv。最活性的杂合8H(MIC:50微克/毫升)是可比较与利福平(MIC:32
(CPFX)‐isatin‐1H‐1,2,3‐triazole hybrids 6a–l with greater lipophilicity compared with the parent CPFX was designed, synthesized, and assessed for their in vitroanti‐mycobacterial activity against Mycobacterium tuberculosis (MTB) H37Rv as well as cytotoxicity in VERO cell line. The preliminary results showed that all hybrids (MIC: 0.39–50 μg/mL) exhibited promising activities against MTB H37Rv, and six

1H‐1,2,3‐triazole‐tethered ciprofloxacin (CPFX) isatin conjugates 5a–h with greater lipophilicity compared with CPFX were designed, synthesized, and evaluated for their in vitroanti‐mycobacterialactivity against Mycobacterium smegmatis and Mycobacterium tuberculosis (MTB) H37Rv. The preliminary results showed that all hybrids (MIC: 12.5–100 μg/mL) exhibited considerable activity against M. smegmatis
设计,合成并评估了八种新颖的1 H 1,2,3-三唑系环丙沙星(CPFX)亲脂性比CPFX高的5a - h缀合物,并评估了它们对耻垢分枝杆菌和结核分枝杆菌的体外抗分枝杆菌活性(MTB)H 37 Rv。初步结果表明,所有杂种(MIC:12.5–100μg/ mL)均表现出对耻垢分枝杆菌的显着活性,但活性低于亲本CPFX(MIC:6.25μg/ mL)和参考INH(MIC:0.78μg/ mL)毫升)。针对MTB H 37Rv,所有杂种均表现出优异的抑制活性,MIC范围为1.56至25μg/ mL,特别是5h(MIC:1.56μg/ mL)的CPFX活性是MIC的两倍(MIC:3.12μg/ mL),有待进一步研究。

Twelve novel isatin‐1,2,3‐triazole‐isatin scaffolds 5a–l were designed, synthesized, and assessed for their in vitro antibacterial activity in this paper. The preliminary results showed that all dimers only endowed with weak antibacterial activity, which was less active than the reference ciprofloxacin. However, the structure–activity relationship was enriched, which may be useful for the further development
