A new series of novel 8,10-dimethyl-12-aryl-12H-naphtho[1,2,5,6]pyrano[2,3-d]pyrimidine-9,11-diones derivatives synthesized from coupling (3CC) of aldehydes, b-naphthol and 1,3-dimethylbarbituric acid derivatives with using green condition through a simple, mild and efficient procedure utilizing cellulose sulfuric acid as a catalyst. Final compounds were evaluated for antibacterial and antifungal activity. Compounds 4a, 4d, 4h display high potent antifungal activity against Candida parapsilopsis, compound 4d show more potent activity (MIC 4.6 mg/mL) better than miconazole. While compound 4d most effective on bacterial against Micrococcus luteus, Staphylococcus aureus MTCC 96 and Staphylococcus aureus MTCC 2940 with (MIC 2.3 mg/mL).
以纤维素硫酸为催化剂,通过简单、温和、高效的程序,利用醛、b-萘酚和 1,3-二甲基巴比妥酸衍生物的偶联(3CC),在绿色条件下合成了一系列新型 8,10-二甲基-12-芳基-12H-萘并[1,2,5,6]吡喃并[2,3-d]嘧啶-9,11-二酮衍生物。对最终化合物进行了抗菌和抗真菌活性评估。化合物 4a、4d 和 4h 对拟白色念珠菌具有很强的抗真菌活性,其中化合物 4d 的活性(MIC 4.6 mg/mL)优于咪康唑。化合物 4d 对黄体微球菌、金黄色葡萄球菌 MTCC 96 和金黄色葡萄球菌 MTCC 2940 的细菌活性最强(MIC 为 2.3 毫克/毫升)。
