9-homoisoflavonoid and flavone scaffolds also showed micromolar activity towards xanthine oxidase. At the same time, dihydrochalcone and Δ2,3-homoisoflavonoid carboxylic acids as well as their oxa-analogues were more than two orders of magnitude less effective inhibitors. Kinetic and molecular docking studies indicated that the carboxylated chalcones and Δ3,9-homoisoflavonoids are mixed-type inhibitors
Synthesis and structure-activity relationship of new chalcone linked 5-phenyl-3-isoxazolecarboxylic acid methyl esters potentially active against drug resistant Mycobacterium tuberculosis
agents active against emerging drug-resistant Mycobacterium tuberculosis and to counter the long treatment protocol of existing drugs, herein we present synthesis and biological evaluation of a new series of 5-phenyl-3-isoxazolecarboxylic acidmethyl ester-chalcone hybrids. Among 35 synthesized compounds, 32 analogues displayed potent in-vitro activity against Mycobacterium tuberculosis H37Rv with MIC
