In present research work, a new series of N-[(dimethyl substituted)phenyl]-N-(4-chlorophenyl)-4- chlorobenzenesulfonamides (5a-f) was synthesized and also evaluated for their biological activities. The reaction of 4-chlorobenzenesulfonyl chloride (1) with dimethyl substituted aniline (2a-f) in aqueous alkaline medium yielded N-[(dimethyl substituted)phenyl]-4-chlorobenzenesulfonamides (3a-f). The target compounds 5a-f were synthesized by reacting the compounds 3a-f with electrophile, 4-chlorobenzyl chloride (4) in aprotic solvent, DMF and NaH. All the synthesized compounds were characterized by IR, 1H NMR and EIMS. All the synthesized derivatives were screened for antibacterial potential and were also subjected for lipoxygenase enzyme inhibition activity.
在当前的研究中,合成了一系列新的N-[(二甲基取代的)苯基]-N-(4-氯苯基)-4-氯苯磺酰胺(5a-f),并评估了它们的生物活性。4-氯苯磺酰氯(1)与二甲基取代的苯胺(2a-f)在碱性水溶液中反应,生成N-[(二甲基取代的)苯基]-4-氯苯磺酰胺(3a-f)。目标化合物5a-f是通过将化合物3a-f与电亲体4-氯苄氯(4)在无质子溶剂DMF和NaH中反应而合成的。所有合成的化合物均通过红外光谱(.IR)、氢核磁共振(1H NMR)和电子离子化质谱(EIMS)进行了表征。所有合成的衍生物都经过了抗菌潜力筛选,并且还进行了脂氧合酶酶抑制活性测试。
