An efficient multi component reaction for the synthesis of new 3‐(2‐amino‐6‐arylpyrimidin‐4‐yl)‐4‐hydroxyquinolin‐2(1 H )‐ones has been described. Synthesized derivatives were screened for their in vitro antimicrobial and 2, 2‐diphenyl‐1‐picrylhydrazyl (DPPH) scavenging activity. Among the tested compounds 3 k , 3 m and 3 r shown better antibacterial properties and have displayed broad spectrum of activity than Neomycin against Staphylococcus aureus , Bacillus cereus, Klebsiella planticola , Escherechia coli, S.aureus and Pseudomonas aeruginosa . Moreover 3 r , 3 t and 3 n were found to have potent antifungal activity against Candida parapsilosis, Candida albicans , Aspergillus niger , Candida glabrata , Issatchenkia hanoiensis and Candida than the standard Miconazole. Furthermore 3 c , 3 j , 3 d , 3 m , and 3 h showed strong DPPH free radical scavenging activity than Ascorbic acid.
