Halogen derivatives of selected 3-benzofurancarboxylic acids were prepared using 6-acetyl-5-hydroxy-2-methyl-3-benzofuranocarboxylic acid as starting material. 1H-NMR spectra were obtained for all of the synthesized structures, and for compound VI, an X-ray crystal structure was also obtained. All derivatives were tested for antimicrobial activity against a selection of Gram-positive cocci, Gram-negative rods and yeasts. Three compounds, III, IV, and VI, showed antimicrobial activity against Gram-positive bacteria (MIC 50 to 200 mg/mL). Compounds VI and III exhibited antifungal activity against the Candida strains C. albicans and C. parapsilosis (MIC – 100 mg/mL).
以 6-乙酰基-5-羟基-2-甲基-3-苯并呋喃羧酸为起始原料,制备了特定 3-苯并呋喃羧酸的卤素衍生物。所有合成结构都获得了 1H-NMR 光谱,化合物 VI 还获得了 X 射线晶体结构。测试了所有衍生物对部分革兰氏阳性球菌、革兰氏阴性杆菌和酵母菌的抗菌活性。三种化合物 III、IV 和 VI 对革兰氏阳性细菌具有抗菌活性(MIC 50 至 200 mg/mL)。化合物 VI 和 III 对白色念珠菌菌株 C. albicans 和 C. parapsilosis 具有抗真菌活性(MIC - 100 mg/mL)。
