Research Peptide
POSTAMAX / KEDP
A Khavinson bioregulator peptide (Lys-Glu-Asp-Pro) targeting prostate tissue. Supports prostate health by reducing inflammation, promoting cellular repair and regeneration, modulating chromatin and gene expression for anti-aging effects in prostate cells, and potentially improving urinary function in models of prostatitis or age-related changes.
Overview
POSTAMAX (also referred to as KEDP, reflecting its Lys-Glu-Asp-Pro tetrapeptide sequence) is a short synthetic peptide studied for its interactions with prostate tissue cellular signaling pathways. As a member of the tetrapeptide bioregulator family — a class of short peptides derived from organ-specific protein complexes — it is investigated for its potential to modulate cellular function through receptor-level and gene-expression-level mechanisms.
The bioregulator peptide class, pioneered largely through Russian pharmaceutical research, encompasses organ-specific short peptides hypothesized to exhibit tissue-directed regulatory activity. KEDP's prostate-tissue research focus makes it a distinctive compound within this category, investigated for receptor binding dynamics and downstream signaling effects in prostate cell models.
Research Highlights
Preclinical research on POSTAMAX/KEDP has investigated its role in prostate cellular pathway modulation, including its potential interactions with androgen-responsive signaling cascades and inflammation-regulatory networks within prostate tissue. Studies have explored its antioxidant and tissue-support properties, characterizing its effects on oxidative stress biomarkers and cell viability under stress conditions.
Research has also examined its use in peptide-receptor binding assays as a probe for understanding prostate cell surface receptor dynamics. As a bioregulator-class tetrapeptide, it is stored at −20°C protected from light and moisture to maintain structural integrity.
