Abstract
A convenient synthesis of certain novel 5,6-disubstituted 2-(substituted amino)alkylthiopyrimidin-4(3H)-ones is reported. 5,6-Disubstituted-2-thiouracils were allowed to react with the appropriate (2-chloroethyl/propyl) amine/imide to give the corresponding 5,6-disubstituted 2-(substituted amino)alkylthiopyrimidin-4(3H)-one derivatives in moderate yields. The antimicrobial potential of the target compounds was determined towards Gram-positive bacteria (Staphylococus aureus, Bacillus subtilis, and Bacillus cereus) and pathogenic fungi (Candida albicans and Aspergillus niger). The obtained data were expressed as diameter of the growth inhibition zone and minimum inhibition concentration (MIC) for the test compounds. The most active compound exhibited dual antibacterial (against S. aureus) and antifungal (against C. albicans) effects with MIC value = 0.0524 A mu mol/cm(3).
