title: Microwave-assisted synthesis and anti-bacterial activity of some 2-amino-6-aryl-4-(2-thienyl)pyrimidines.
abstract: Some novel 2-amino-6-aryl-4-(2-thienyl)pyrimidines were synthesized from 3-aryl-1-thien-2-ylprop-2-en-1-ones and guanidine hydrochloride in presence of alkali by conventional heating in alcoholic medium and microwave heating in solvent-free conditions. The compounds were evaluated for in vitro anti-bacterial activity. The anti-bacterial data revealed that compounds 5a-e had better activity against tested gram-positive organisms than the reference ciprofloxacin and norfloxacin. However, the compounds were nearly inactive against gram-negative bacteria. Compounds 5c and e were the most active compounds against gram-positive bacteria.
