Convenient method for preparation of esters of N-carbonyl-?-amino acids

Autor: S. V. Rogozhin, O. M. Galkin, V. I. Butaeva, Yu. A. Davidovich, T. N. Sentsova

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 26:1554-1556

A convenient method was proposed for obtaining the esters of N-carbonyl-α-amino acids, which is based on the reaction of the esters of N-trimethylsilyl-α-amino acids with phosgene in the presence of a tertiary amine.

[Excitatory effect of tuftsin tetrapeptide on the activity of white rats]

Autor: A A, Kamenskiĭ, L V, Antonova, N A, Samoĭlova, O M, Galkin, S M, Andreev

Publikováno v: Biulleten' eksperimental'noi biologii i meditsiny. 89(7)

Studies on male white rats have shown that tuftsin (trelys-pro-arg) enhances the locomotion in animals as disclosed by a series of the behavioral tests. The effect is dose-dependent: a dose of 50 microgram/kg did not change any of the test parameters
