A series of potential biologically active 4,5-dimethoxy-2-[3-oxo-3-phenylprop-1-en-1-yl]benzenesulfonamides was synthesized. 3,4-Dimethoxybenzaldehyde was condensed with acetophenone followed by its chlorosulfonation to get 4,5-dimethoxy-2-[3-oxo-3-phenylprop-1-en-1-yl]benzenesulfonyl chloride, which was further reacted with a number of amines and hydrazides to get the 4,5-dimethoxy-2-[3-oxo-3-phenylprop-1-en-1-yl]benzenesulfonic acid derivatives. All the synthesized compounds were subjected to preliminary evaluation for their antibacterial activity against selected strains of gram positive and gram negative bacteria. Some of the assayed compounds showed marked activity.
合成了一系列具有潜在生物活性的 4,5-二甲氧基-2-[3-氧代-3-苯基丙-1-烯-1-基]苯磺酰胺。将 3,4-二甲氧基苯甲醛与苯乙酮缩合,然后进行氯磺化反应,得到 4,5-二甲氧基-2-[3-氧代-3-苯基丙-1-烯-1-基]苯磺酰氯,再与一些胺和酰肼反应,得到 4,5-二甲氧基-2-[3-氧代-3-苯基丙-1-烯-1-基]苯磺酸衍生物。对所有合成的化合物进行了初步的抗菌活性评估,以确定其对所选的革兰氏阳性和阴性菌株的抗菌活性。其中一些化合物显示出明显的活性。
