摘要

Novel 5-phenyl-1,5-dihydro-2H-chromeno[2,3-d]pyrimidine-2,4(3H)-dithiones, 5-phenyl-3,5-dihydro-4H-chromeno[2,3-d]pyrimidin-4-ones, 7-phenyl-7,9-dihydro-8H pyrimido[5′,4′:5,6]pyrano[3,2-h]quinolin-8-ones, and 4-amino-5-phenyl-1,5-dihydro-2H-chromeno[2,3-d]pyrimidine-2-thiones were synthesized form 2-amino-4-phenyl-4H-chromene-3-carbonitrile. The newly synthesized compounds were characterized by IR, 1H-NMR, 13C-NMR, Mass spectra, and Elemental analysis. The compounds were evaluated for their in vitro antitubercular activity against Mycobacterium tuberculosis H 37 Rv and antibacterial activity against Staphylococcus Aureus [ATCC-25923] and Streptococcus pyogenes [MTCC-443] as Gram-positive, Escherichia coli [ATCC-25922], and Pseudomonas aeruginosa [MTCC-441] as Gram-negative bacterial strains and antifungal activity against Aspergillus niger [MTCC-282]. Some of these derivatives exhibited pronounced antitubercular and antimicrobial activities.
