elemental analysis. All the synthesized compounds were subjected to antibacterial activity against the Gram positive bacteria Staphylococcus aureus, Bacillus subtilis, and Streptococcus haemolytius and the Gram negative bacteria Salmonella typhi, Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumonia. The analgesic activity was carried out using Swiss albino male mice by abdominal concentration
摘要 新型 4-hydroxy-3-(phenylthio)-2H-chromen-2-ones 4a-k 和 4-hydroxy-3-[imidazol/tetrazolo-2-yl)thio]-2H-chromen 的温和高效合成-2-ones 6a–d 被描述。化合物 4a-c 进一步被 m-CPBA 氧化得到 3-(苯磺酰基)-4-羟基-2H-chromen-2-ones 5a-c。所得新化合物的结构通过IR、1H NMR、质量和元素分析确定。所有合成的化合物均对革兰氏阳性菌金黄色葡萄球菌、枯草芽孢杆菌和溶血链球菌和革兰氏阴性菌伤寒沙门氏菌、大肠杆菌、铜绿假单胞菌和肺炎克雷伯菌具有抗菌活性。镇痛活性采用瑞士白化雄性小鼠腹腔浓缩法进行。补充材料可用于本文。转至出版商在线版的磷、硫和硅及相关元素,查看免费的补充文件。图形概要
