Abstract: | "We report a general method for acylation of the N epsilon-amino group of the lysyl residue in peptides. The procedure involves acylation using p-nitrophenyl esters and 1-hydroxybenzotriazole in organic solvents to yield a series of fatty acyl mating pheromones of Saccharomyces cerevisiae. The fatty acyl group does not influence coupling of peptide fragments. Biological activities of the synthesized alpha-factor mating pheromones derivatized with acetyl, butyryl, caprylyl and lauryl groups are nearly equivalent to the activity of unacylated alpha-factor. The N epsilon-stearyl-alpha-factor is biologically inactive. The procedures reported in this communication can be used to increase hydrophobicity of lysine-containing peptides when the lysyl group is not essential for activity" |
