PEPTIDE WITH IMMUNO-SIMULATING ACTIVITY AND PREPARATION BASED ON SUCH PEPTIDE

摘要

FIELD: peptide synthesis. SUBSTANCE: invention provides new peptide with general formula I: (I) wherein R is hydrogen, lower alkyl, or lower acyl; X heteroaromatic amino acid residue; and n=1 or 2; on condition that, when residue RNHCH(COOH)(CH2)nCO- is glutamic acid residue (n= 2), then X has stereo configuration different from that at alpha-carbon atom of glutamic acid having immuno-simulating activity. Preparation having such activity and containing peptide I (0.001 to 0.01 %) and special additives (the balance) is also provided. EFFECT: enlarged choice of immuno-simulating peptides. 2 cl, 11 tbl, 15 ex
