hydrazide in glacial acetic acid, which led to the formation of novel 4-[5-(substituted phenyl)-1-phenyl-4,5-dihydro-1 H -3-pyrazolyl]-2-methylphenol derivatives. All newly synthesized compounds were evaluated for their antimycobacterial activities against isoniazid-resistant Mycobacterium tuberculosis using agar dilution. 4-[5-(4-Fluoro phenyl)-1-phenyl-4,5-dihydro-1 H -3-pyrazolyl]-2-methylphenol
在目前的研究中,4-羟基-3-甲基苯乙酮与适当的醛在氢氧化钾甲醇溶液中缩合,生成相应的查耳酮(CI -XI)。这些相应的查耳酮在冰醋酸中与酰肼反应,导致形成新的4- [5-(取代的苯基)-1-苯基-4,5-二氢-1 H -3-吡唑基] -2-甲基苯酚衍生物。使用琼脂稀释液评估所有新合成的化合物对耐异烟肼 结核分枝杆菌的抗分枝 杆菌活性 。4- [5-(4-氟苯基)-1-苯基-4,5-二氢-1 H -3-吡唑基] -2-甲基苯酚显示出良好的抗分枝杆菌活性,最低抑制浓度为0.62μg/ ml。
