Synthesis and Anti‐Inflammatory Activity of Pyrazolines [PDF]
Journal of Chemistry, 2009 Some new pyrazoline derivatives were synthesized by reacting chalcones of 2‐acetyl thiophene with phenyl hydrazine hydrochloride in the presence of alcohol. The synthesized compounds were identified by spectral data and screened for anti‐inflammatory activity. Some of these compounds showed moderate to considerable anti‐inflammatory activity.
