Summary

Phe(12) of deacetyl-thymosin beta(4) is one of the structural essentials for restorative effect on the impaired blastogenic response of uraemic T-lymphocytes. In order to evaluate the functional roles of this phenyl group in the restorative effect on impaired T-lymphocytes, two analogues, [1- Nal(12)]deacetyl-thymosin beta(4) and [Cha(12)]deacetyl4 thymosin beta(4), were synthesized by a solid-phase method and evaluated for restorative effect on the impaired blastogenic response of uraemic T-lymphocytes. The results indicated that [1-Nal(12)]deacetyl-thymosin beta(4) which had a bulky naphthyl ring showed a stronger restorative effect than that of deacetyl-thymosin beta(4), but it was slightly weaker than that of [Phe(4F)(12)]deacetyl-thymosin beta(4). However, [Cha(12)]deacetyl-thymosin beta(4) showed no restorative effect on the impaired blastogenic response of uraemic T-lymphocytes.

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. 01LabNot a test of Thymosin beta-4 (human) aloneEx vivo tissueEfficacy outcome

    In uraemic T-lymphocytes, the [1-Nal(12)] analog restored the impaired blastogenic response more strongly than deacetyl-thymosin beta‑4 and slightly less than the [Phe(4F)(12)] analog.

    In plain wordsIn cells, an analog of thymosin beta‑4 restored impaired T-cell response more strongly than deacetyl-thymosin beta‑4.
