A new series of 4-aryl-3,4-dihydrocoumarins and 4-arylcoumarins were synthesized by the reaction of substituted cinnamic acids and 3-arylpropiolic acid with the corresponding phenols. These compounds were evaluated for antibacterial activity in vitro. The synthesized compounds displayed different degrees of antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Bacillus dysenteriae, and Candida albicans (a fungus). Compounds with catechol moieties and 7,8-substituted dihydroxyls in the A ring were the most active antimicrobial agents.
通过取代肉桂酸和3-芳基炔酸与相应的酚反应,合成了一系列4-芳基-3,4-二氢香豆素和4-芳基香豆素。这些化合物在体外评估了抗菌活性。合成的化合物对金黄色葡萄球菌、大肠杆菌、痢疾杆菌和白色念珠菌(真菌)表现出不同程度的抗微生物活性。具有羟基苯环和7,8-取代二羟基的A环化合物是最活跃的抗微生物剂。
