2-methyl-5-(5-phenyl-thiazolo[5,4-d]isoxazol-6(5H)-yl)thieno[3,4-d]pyrimidin-4(3H)-one have been prepared under microwave-assisted and conventional conditions. The new compounds were screened for their in vitro antimicrobial activity against two gram-positive bacteria (Bacillus subtilis NCIM-2063 and Staphylococcus aureus NCIM-2901), one Gram-negative bacteria (Escherichia coli NCIM-2256), and three fungal strains (Candida
新的 2-methyl-5-(4-oxo-2-(取代苯基)thiazolidin-3-yl)thieno[3,4-d]-pyrimidin-4-one, 5-(2,7-diphenyl-5- thioxo-5,6,7,7a-四氢噻唑并[4,5-d]嘧啶-3(2H)-基)-2-甲基噻吩并[3,4-d]嘧啶-4(3H)-one,和2-微波辅助下制备了甲基-5-(5-苯基-噻唑并[5,4-d]异恶唑-6(5H)-基)噻吩并[3,4-d]嘧啶-4(3H)-one常规条件。筛选了新化合物对两种革兰氏阳性菌(枯草芽孢杆菌 NCIM-2063 和金黄色葡萄球菌 NCIM-2901)、一种革兰氏阴性菌(大肠杆菌 NCIM-2256)和三种真菌菌株(念珠菌)的体外抗菌活性白色念珠菌 NCIM-3471、黄曲霉 NCIM-539 和黑曲霉 NCIM-1196)并显示出有希望的生物活性。
