Main Article Content


Compounds bearing and amino acid moieties are considered the basis for sulfa drug development. The synthesis of 4-methylphenylsulphamoyl acids and the evaluation of their pharmacological activities are reported. The synthesis of these compounds was accomplished by the reaction of various acids and 4-methyl chloride in basic aqueous solution. Structures were confirmed by FTIR, 1HNMR, 13CNMR spectra and elemental analytical data. Molecular docking interactions of the analogues were determined using PyRx. In the in antimicrobial activity analysis, compounds 1, 3, 5and 7 had antimicrobial inhibitory concentration range of 0.5-1.0mg/ml comparable with 0.1-2.0mg/ml of and . In the in anti-oxidant activity study compounds 1, 2and 6displayed half-maximal inhibitory concentrations (IC50) of 1.104±0.001 /ml, 1.159±0.002µg/ml and1.240±0.001µg/ml respectively comparable with 0.999±0.002µg/ml of acid. In the molecular docking study, compound 4 had a strong 2D binding interaction with II amino acid residue and compounds 1, 3, 4, 5, 6 and 7 had in antimicrobial, anti-oxidant, and antimalarial properties similar to their standard drugs. Considering the outstanding pharmacological properties and their strict compliance with Lipinski’s rule, the synthesized 4-methylphenylsulphamoyl analogues could be considered as antimicrobial, antimalarial, and anti-oxidant drug candidates.
