The antiinflammatory effect of a series of aryloxoalkanoic acids II and of their biphenyl derivatives III was examined by measuring the inhibition of the development of carageenan- and adjuvant-induced edemas. The quantitative relations between the antiinflammatory effect and physicochemical and structural parameters of the compounds tested were evaluated. The equations obtained by the method of regression analysis showed a significant linear dependence of both inhibitory activities on the lipophilicity of the compounds and a considerable effect of some structural changes as expressed by indicator variables. The antiinflammatory effect is especially enhanced in both tests by the presence of a cyclic substituent at the aromatic ring. The high antiinflammatory effect of biphenylyl derivatives III is paralleled by their prolonged action. The prolongation of the effect is most likely a result of a suitable biotransformation of acid III to an efficient metabolite. The structural requirements which resulted from both the regression analysis and from the hypothesis of biotransformation of acids III were utilized in the synthesis of suitably substituted biphenylyloxoalkanoic acids. By this approach derivatives IIIe-i were obtained some of which showed a high antiinflammatory and also protracted effect. 4-(2',4'-Difluorbiphenylyl)-4-oxo-2-methylbutanoic acid (VÚFB-16 066, Flobufen) was chosen for further preclinical development.

A series of 2,4-dihydroxy-3-propylacetophenone derivatives containing alkylthiobenzoic or arylacetic acid moiety was prepared. The antileukotrienic activity of the substances was assessed in terms of inhibition of the biosynthesis of LTB4 and bonding to LTB4 and LTD4 receptors. Some of the substances were found to exert a complex antileukotrienic effect in all of the three tests. The compounds also displayed an antiinflammatory effect, as manifested by a significant inhibition of LTD4-induced bronchospasm.

Two {Met(0)6}deacetyl-thymosin β4analogs containing Phe(4F) or Tyr(Me) at position 12 were synthesized by the manual solid-phase method, and their anti-inflammatory effect on carrageenin-induced edema in the mouse paw was studied. Fluorination of the para-position of Phe12resulted in a marked antiinflammatory effect on carrageenin-induced edema in the mouse paw compared with that of our synthetic {Met(0)6}deacetyl-thymosin β4, but the other analog, {Met(0)6, Tyr(Me)12}deacetyl-thymosin β4, showed a marked reduction of the anti-inflammatory effect.
