  Synthesis of novel thiopyrimidines: an investigation of anti-tubercular and antimicrobial activity

  摘要：

  A variety of novel sulfur-containing tricyclic pyrimidine derivatives have been synthesized via the reaction of 2-amino-4-oxo-4H-chromene-3-carbonitriles 3(a-f) with different reagents and characterized by IR, H-1 NMR, C-13 NMR, mass spectrometry and elemental analysis. The anti-tubercular and antimicrobial activities of the synthesized compounds were investigated.[GRAPHICS].

  The preparation of a series of novel chromone-fused cytosine analogues, i.e., chromeno[2,3-d]pyrimidines has been carried out from substituted 2-amino-4-oxo-4H-chromene-3-carbonitriles with urea, thiourea, and guanidine under different reaction conditions. These chromone-fused cytosine analogues were evaluated for their in vitro activity against Mycobacterium tuberculosis H(37)Rv strain and different microbial pathogenic strains in cell culture for their structure-activity relationships, respectively. Among the synthesized compounds, 2d, 3a, and 4e showed better results against Mycobacterium tuberculosis H(37)Rv. The compounds 2a, 2b, and 3a showed potential antibacterial activity against E. coli and P. aeruginosa, while the majority of compounds were found to be active against S. aureus as compared to ampicillin. The synthesized cytosine analogues having an imine (-CNH) have been less sensitive to the bacterial and fungal strains but have a more beneficial effect on Mycobacterium tuberculosis H(37)Rv.

  A series of functionalized H‐[1]benzopyrano[2,3‐b]pyridine derivatives were synthesized by the Friedländer reaction of 2‐amino‐4‐oxo‐4H‐chromene‐3‐carbonitriles 1 with malononitrile, ethyl cyanoacetate, or acetophenone (Scheme). The synthesized compounds 2–4 were screened for their in vitro activity against antitubercular, antibacterial, and antifungal species (Fig., Table). Among the synthesized compounds
