Biopolymer Catalysed Synthesis of 6-methyl-4-phenylcarbamoyl-1, 2, 3, 4- Tetrahydropyrimidine-2-ones and Evaluation of their Anti-bacterial and Anti-tubercular Activities

Background: An efficient one-pot biocatalysed ultrasound assisted synthesis of dihydropyrimidinones/ thiones has been developed under solvent free conditions. Materials and Methods: The use of biodegradable, non toxic, agar-powder as a catalyst provide advantages like high yield, simple operation, mild reaction condition with short reaction time. 1,2,3,4- tetrahydropyrimidine-2-ones/thiones formed were characterized by mass and 1H NMR spectroscopy. Results: The dihydropyrimidinones substituted with electron donating groups like fluorine, hydroxy along with thienyl groups exhibited good antibacterial activity. The compounds exhibited favorable binding interactions with mycobacterium target protein H37Rv. Conclusion: 4-methoxy substituted dihydropyrimidinones derivative showed significant antituberculosis activity.
