Prostamax (KEDP) is a synthetic short-chain tetrapeptide (Lys-Glu-Asp-Pro) belonging to the Khavinson class of tissue-specific peptide bioregulators, studied in connection with prostate and genitourinary tissue.
Prostamax is a defined-sequence synthetic tetrapeptide composed of lysine, glutamic acid, aspartic acid, and proline (Lys-Glu-Asp-Pro; KEDP). It is produced by solid-phase peptide synthesis and characterized as a member of the Khavinson family of short-peptide bioregulators originally developed for prostate-associated investigation.
Unlike receptor-mediated signaling peptides, Prostamax appears to function through structural modulation of the DNA-protein complex, with characterized activity centered on chromatin organization, gene expression, and tissue-specific cellular responses. It has been reported to activate ribosomal genes, decondense densely packed chromatin, and release genes repressed by age-specific chromatin condensation, with one model noting induced decondensation in chromosome 1 pericentromeric regions. These mechanisms position it as a tool for examining epigenetic regulation and chromatin dynamics in prostate cell cultures and lymphocyte-based systems.
