This new procedure has the advantages of mild reaction condition, high yields, and metal-free catalyst. A library of 22 pyranoquinolinone derivatives, with substituents at positions 2, 3, 4, and 5 were synthesized and screened against a series of reference strains of bacteria and fungi of medical relevance. The SAR analyses of the most promising results showed that the antimicrobial activity of the compounds depends on the substituents attached to the pyran ring.</Abstract> <AbstractLanguage>English</AbstractLanguage> <Keywords>Aromatase, 4-Hydroxy-1-methyl-2(1H)-quinolinone, knoevenagel condensation, pyranoquinolinones, antimicrobial activity</Keywords> <URLs> <Abstract>https://isfcppharmaspire.com/ubijournal-v1copy/journals/abstract.php?article_id=13771&title=Design, synthesis and evaluation of some newly synthesized Pyranoquinolinone derivatives as potential antimicrobial agents</Abstract> </URLs> <References> <ReferencesarticleTitle>References</ReferencesarticleTitle> <ReferencesfirstPage>16</ReferencesfirstPage> <ReferenceslastPage>19</ReferenceslastPage> <References>Franco BE, Martand;iacute;nez MA, Rodrand;iacute;guez MS, Wertheimer AI.
