SYNTHESIS AND ANTIMICROBIAL ACTIVITY OF 1-(4-ARYL-2-THIAZOLYL) – AND 1-(4-ARYL-2-OXAZOLYL)-3, 5-DIARYL Δ2-PYRAZOLINE DERIVATIVES
AbstractA series of nine 1-(4-aryl-2-thiazolyl)-3, 5- diaryl and six of 1- (4- aryl- 2-oxazolyl)-3, 5- diaryl- 2- pyrazolin derivatives were prepared by reacting 3, 5-diaryl-1- thiocarbamoyl-/or 3, 5- diaryl- 1- carbamoyl- D2– pyrazolines with substituted phenacyl bromide in ethanol. The structures of the synthesized derivatives were confirmed by IR, 1H-NMR, 13C-NMR as well as EIMS spectral data. Some of these derivatives were screened for their antimicrobial activity against Gram-positive, Gram- negative and pathogenic fungi, and showed a significant activity.
