Synthesis and antiinflammatory activity of novel 3-(2,3-dimethyl-1-phenyl-4-pyrazolon-5-yl)-4-thiazolidones.

New 3-(2,3-dimethyl-1-phenyl-4-pyrazolon-5-yl)-4-thiazolidones were synthesized. The structure of substances was supported by UV- and 1H-NMR spectra. Some compounds were tested in vivo for their antiinflammatory activity. Were confirmed previous results about structure-activity relationships.
