A remarkable diastereoselective synthesis of some novel arylthiazolyl pyrazoline derivatives 3(a-l) is displayed which were evaluated for their in vitro antimicrobial activities. In particular, compounds 3e, 3g & 3l (MIC 12.5µ g /ml) showed good activity against S. aureus and compounds 3b & 3j (MIC 12.5 µ g / ml) against B. subtilis. Compounds 3g, 3i, 3j (MIC 12.5 µ g/ ml) and 3l (MIC 6.25 µg / ml) also displayed excellent antifungal activity against C. albicans. Of all the synthesized compounds, 3g and 3e exerted a wide range of antibacterial activities against entire tested gram positive (S. aureus and B. subtilis) and gram negative (E. coli and P. aeruginosa) bacterial strain except P. aeruginosa.
