Description
Prostamax is a synthetic ultrashort tetrapeptide research reagent (also known as a Khavinson peptide). It is chemically distinct for its ability to penetrate the cell nucleus and act directly on DNA chromatin, functioning as an epigenetic switch. Researchers employ this molecule to investigate the molecular mechanisms of tissue-specific bioregulation, specifically exploring its anti-aging and anti-inflammatory effects on the prostate gland, as well as its capacity to optimize the function and reactivate the chromatin of human lymphocytes in gerontological models.
Biochemical Characteristics
- Sequence/Structure: Peptide (4 amino acids); Lys-Glu-Asp-Pro (KEDP).
- Permeability: Demonstrates high cellular and nuclear permeability, actively transported via LAT and PEPT family carriers to interact directly with intracellular heterochromatin.
- Stability: Supplied as a lyophilized salt to ensure long-term stability and prevent hydrolytic degradation during storage.
- Specificity: Highly specific intracellular signaling molecule that induces deheterochromatinization (unrolling of chromatin) and activation of ribosomal genes in targeted tissues, particularly the prostate and immune system.

Prostamax is strictly for laboratory research and is commonly employed in the following investigational areas:
Prostate Health and Chronic Prostatitis
Research models utilize Prostamax to evaluate its efficacy in the management of prostate dysfunction. Investigations focus on the peptide’s anti-inflammatory properties, quantifying changes in tissue morphology and cellular recovery in experimental models of chronic aseptic prostatitis and its associated complications.
Epigenetics and Chromatin Reactivation
Experimental protocols employ this tetrapeptide to characterize its direct interactions with human DNA. Studies assess its influence on lymphocyte heterochromatin in situ, specifically measuring its ability to induce the decondensation (unrolling) of chromatin and reactivate ribosomal genes in senile subjects or aging cellular models.
Immune Modulation and Secretory Function
In immunological and gerontological research, Prostamax is used to study the broader peptide bioregulation of the immune system. Researchers evaluate how it affects the state of secretory immunity (e.g., in the saliva of elderly patients) and alters epigenetic controls to optimize lymphocyte function.
Pathway / Mechanistic Context
The primary mechanism of action for Prostamax in research settings involves its function as an epigenetic regulator and intracellular signaling molecule.
- Cellular Transport and Nuclear Penetration: Utilizes membrane peptide transport systems (such as LAT and PEPT family transporters) to bypass the cellular membrane and enter the nucleus.
- Chromatin Decondensation: Interacts directly with DNA and histones to induce deheterochromatinization, unrolling tightly packed heterochromatin to make genetic information accessible.
- Gene Activation and Tissue Repair: Activates ribosomal genes and stimulates targeted protein synthesis, which subsequently reduces inflammation, promotes cellular longevity, and supports structural recovery in the prostate and immune cells.
Preclinical Research Summary
Published preclinical literature documents investigations of Prostamax across diverse experimental models focusing on epigenetics, prostate health, and aging.
- In urological models, experimental studies of Prostamax demonstrated significant efficiency in the therapy of chronic aseptic prostatitis, reducing inflammation and supporting tissue recovery.
- In vitro gerontological studies utilizing human lymphocytes from senile subjects showed that Prostamax induces the reactivation of chromatin and activates ribosomal genes.
- Computational and in vitro research on cellular transport mechanisms confirmed the feasibility of transporting biologically active ultrashort peptides like Prostamax via LAT and PEPT family solute carriers.
- Clinical-translational observations indicate that peptide bioregulation effectively modulates secretory immunity and supports structural homeostasis in aging cohorts with conditions like chronic generalized periodontitis.
