Abstract: | A TP II analogue, 1-Nal3] TP II, was synthesized by a conventional solution method, followed by deprotection with 1M TFMSA-thioanisole (molar ratio 1:1) in TFA in the presence of Me2Se and m-cresol as scavengers. The synthetic 1-Nal3] TP II, TP II and Phe (4 F)3] TP II were tested for comparative effect on the impaired T-lymphocyte transformation by PHA in uremic patients suffering from recurrent infectious diseases. The synthetic analogue was found to have stronger restorative activity than those of our synthetic TP II and Phe (4F)3] TP II. |
