摘要:
New thymopentin (TP5) analogues whose bonds in the peptide chain are all retro-inverted are disclosed. Such new compounds have the following general formula (I) wherein R is hydrogen or an acyl radical, and R¹ is a group of the formula -OR², wherein R² is a hydrogen atom or a hydrocarbon radical, and the corresponding basic or acid addition salts which are pharmaceutically acceptable. The new compounds have immunostimulating activity.
摘要:
It is described the capability of the Oncogen Necrosis Factor to potentiate in vivo the primary and secondary immune response against low immunogenic antigens and the use of this factor for the preparation of pharmaceutical compositions useful in the therapy of human beings.
摘要:
New thymopentin (TP5) analogues are disclosed which contain in their peptide chain one or more retro-inverse bonds. The new compounds have one of the following general formulas (I), (II) and (III) wherein R is hydrogen or an acyl radical, and R¹ is a group of the formula -OR² wherein R² is a hydrogen atom or a hydrocarbon radical, and the corresponding acid or basic addition salts pharmaceutically acceptable. Such new compounds have immunostimulating activity.
摘要:
The invention is concerned with compounds analogous to tuftsin, having the formula (I) or of a pharmaceutically acceptable base-addition or acid-addition salt thereof, and the use of them in vaccines as an adjuvant in order to potentiate, in a living organism, the antibody response against either natural or synthetic antigens, as well as with the novel compositions for vaccines which comprise one or more of said antigens together with an adjuvating amount of the compound of formula (I) or of one of its addition salts.
摘要:
New analogues of thymopentin (TP5) and of its tetrapeptide fragment (TP5¹⁻⁴) containing two non-contiguous retro-inverted bonds in the peptide chain are described. The new compounds, of general formula (I) where R is hydrogen or an acyl radical, and R¹ is an -OR² group or an group where R² is a hydrogen atom or a hydrocarbon radical, and R³ is a hydrogen atom or a hydroxyl group, and the corresponding pharmaceutically acceptable salts of acid or basic addition, possess immunomodulating activity.
