[Synthesis and pharmacologic activity of new derivatives of salicylic acid].

New 1-phenyl-2-R2-3-methyl-5-salicyloylimmino-3-pyrazolines were synthesized according to a previously described route. The obtained pyrazoline derivatives, together with some others reported in previous papers, were tested for analgesic and antiinflammatory activities. Some derivatives showed analgesic and/or antiinflammatory activity similar to that of acetylsalicylic acid.
