4-dihydropyridine-3,5-dicarbamoyl derivatives with lipophilic groups have demonstrated excellent antitubercular activity. We have synthesized new N-aryl-1,4-dihydropyridines bearing carbethoxy and acetyl group at C-3 and C-5 of the DHP ring. In addition, 1H-pyrazole ring is substituted at C-4 position. The lowest minimum inhibitory concentration value, 0.02 μg/mL, was found for diethyl 1-(2-chlorophenyl)-1,4-dihydro-2
1,4-二氢吡啶类是新兴的抗结核药。近来,研究表明具有亲脂性基团的1,4-二氢吡啶-3,5-二氨基甲酰基衍生物已显示出优异的抗结核活性。我们合成了在DHP环的C-3和C-5处带有甲乙氧基和乙酰基的新的N-芳基-1,4-二氢吡啶。另外,在C-4位上取代有1个H-吡唑环。对二乙基1-(2-氯苯基)-1,4-二氢-2,6-二甲基-4-(1,3-二苯基-1 H-吡唑- 4-基)吡啶-3,5-二羧酸4e使其比一线抗结核药物异烟肼更有效。另外,该化合物表现出相对较低的细胞毒性。
