A series of several new isoniazid derivatives, isonicotinic acid 2-(2-hydroxy-8-substituted-tricyclo[7.3.1.02.7]tridec-13-ylidene)-hydrazides, were synthesized and fully characterized. These new isoniazid derivatives were studied regarding their antibacterial activity and cytotoxicity, as well as their influences on some metabolizing enzymes. The best anti-mycobacterial activity was observed in the
合成了一系列几种新的异烟肼衍生物,即异烟酸2-(2-羟基-8-取代的三环[7.3.1.0 2.7 ] tridec-13-亚烷基)-酰肼,并对其进行了充分表征。研究了这些新的异烟肼衍生物的抗菌活性和细胞毒性,以及它们对某些代谢酶的影响。对于在三环[7.3.1.0 2.7 ] tridec-13-亚烷基基团的8位上含有烷基侧链的化合物,观察到最佳的抗分枝杆菌活性。相反,这些新化合物对各种非结核菌株的抗菌活性显示出最好的活性是与化合物6的苯基侧链有关。。它也被证明是最具毒性的,可诱导细胞凋亡并阻止G0 / G1期的细胞周期。化合物3也将细胞周期阻滞在G0 / G1期,但是该化合物没有显示任何毒性。所有化合物均诱导HT-29细胞系中NAT1和NAT2基因的表达,以及HT-29和HCT-8细胞系中CYP1A1的表达。CYP3A4的表达水平增加了化合物1,6和7在HCT-8细胞中。这些结果表明,除异
