Abstract

Two hexapeptide and two tetrapeptide analogues of the bioactive hexapeptides [(Trp/Met/Phe)-Lys-Tyr-(Met/Val[hair space])-(Pro/Val)-Met] have been synthesized by incorporating novel peptide isosteres such as 2-isoxazoline, (E[hair space])-alkene, and reduced amide isosteres. These immunomodulating hexapeptides are known to stimulate the formation of inositol phosphates in lymphocyte cell lines.
