Summary

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.

Results from this study2

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone2

In this study, Thymosin beta-4 (human) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Thymosin beta-4 (human).

  1. 01AnimalNot a test of Thymosin beta-4 (human) aloneAnimal study (in vivo)Efficacy outcome

    In mice with carrageenin-induced paw edema, the Phe(4F)12 analog of deacetyl-thymosin beta4 had a markedly stronger anti-inflammatory effect than the parent synthetic deacetyl-thymosin beta4.

    In plain wordsIn mice, one lab-made Tbeta4 analog reduced paw swelling more than the parent compound did.

    In mice with carrageenin-induced paw edema, the Tyr(Me)12 analog of deacetyl-thymosin beta4 showed a marked reduction of the anti-inflammatory effect.

    In plain wordsIn mice, a second lab-made Tbeta4 analog had a much weaker effect on paw swelling than the parent compound.
