Novel lipidic enaminones from a C18 keto-allenic ester.

abstract：:Two novel lipopeptides, which have the peptide ligands [alpha-melanocyte stimulating hormone (alpha-MSH)] sequence and repeated [Gly-Arg-Gly-Asp-Se (GRGDS) sequence], are designed, synthesized by the solid-phase method, and introduced into liposome membranes by the freeze-thaw method. These liposomes bearing the pepti...
