Syntheses of two deacetyl-thymosin beta4 analogs and their anti-inflammatory effect on carrageenin-induced edema in the mouse paw.
Two [Met(0)6]deacetyl-thymosin beta4 analogs 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 Phe12 resulted in a marked antiinflammatory effect on carrageenin-induced edema in the mouse paw compared with that of our synthetic [Met(0)6]deacetyl-thymosin beta4, but the other analog, [Met(0)6, Tyr(Me)12]deacetyl-thymosin beta4, showed a marked reduction of the anti-inflammatory effect.
