FOXO4-DRI (FOXO4-D-Retro-Inverso) is a synthetic senolytic research peptide designed to interfere with the interaction between the transcription factor FOXO4 and the tumor-suppressor protein p53. This interaction is associated with the survival of senescent cells. By disrupting the FOXO4–p53 interaction, FOXO4-DRI has been investigated for its ability to promote apoptosis, or programmed cell death, in selected senescent-cell models.

FOXO4-DRI is a synthetic D-retro-inverso (DRI) peptide developed as a research tool for investigating the molecular mechanisms underlying cellular senescence. The peptide is derived from a region of the FOXO4 forkhead domain and was designed to interfere with the interaction between FOXO4 and the tumor-suppressor protein p53, a protein-protein interaction that has been implicated in the survival of senescent cells.
In preclinical research, FOXO4-DRI has been studied for its potential senolytic activity, referring to the selective targeting and removal of certain senescent cells. Experimental studies suggest that FOXO4-DRI competes with endogenous FOXO4 for binding to p53. This disruption can promote the redistribution of activated p53 away from the nucleus and contribute to the activation of apoptosis-related pathways in susceptible senescent cells.

Research involving cultured human cells has reported that FOXO4-DRI can reduce the viability of selected senescent cell populations while showing comparatively less effect on non-senescent cells under certain experimental conditions. Studies have investigated its activity in several cellular models, including fibroblasts and chondrocytes, providing researchers with a tool for examining the relationship between cellular senescence, p53 signaling, and programmed cell death.

FOXO4-DRI: Research

Targeted Apoptosis of Senescent Cells Restores Tissue Homeostasis in Response to Chemotoxicity and Aging

This is the foundational study associated with FOXO4-DRI. The researchers investigated the FOXO4–p53 interaction and developed an all-D-amino-acid peptide designed to disrupt this interaction. In cellular and mouse models, FOXO4-DRI was investigated for its ability to induce apoptosis in senescent cells and improve selected measures of tissue homeostasis.

Structural plasticity of the FOXO-DBD:p53-TAD interaction

This study provides additional structural insight into the FOXO4–p53 interaction, which is directly relevant to understanding the molecular basis of FOXO4-DRI activity. It focuses on the structural flexibility and interaction between FOXO proteins and the p53 transactivation domain.

  • Molecular biology and biochemical studies

Important Notice

All products are intended for research use only and are not for human or animal consumption, therapeutic use, or clinical application.

Why Buy From Us

At Licensed Peptides™, quality isn’t a claim. it’s a controlled, repeatable process.

Every peptide we produce follows a strict, pharma-grade workflow designed to ensure purity, stability, and consistency from synthesis to delivery.

What sets us apart:

ISO-Certified Cleanroom Manufacturing

All peptides are synthesized in sterile, controlled environments to eliminate contamination risk and ensure batch consistency.

>99% Verified Purity (HPLC Tested)

We use advanced High-Performance Liquid Chromatography (HPLC) to separate and verify peptide purity with precision.

Comprehensive Safety Testing

Each batch undergoes heavy metal and endotoxin screening to ensure it is free from hidden contaminants.

Pharma-Grade Raw Materials

We start with rigorously tested amino acids and reagents, ensuring integrity at the molecular level.

Lyophilized for Stability

Freeze-dried peptides maintain long-term stability, potency, and reliability for research applications.

Nitrogen-Sealed Vials

Every vial is protected from oxygen and moisture, preserving structural integrity during storage and transit.

Built for Serious Research

From synthesis to delivery, every step is engineered to meet the expectations of professionals who require accuracy, consistency, and reliability.

 

Shipping

We understand that timing and product integrity are critical for research.

Same-Day Shipping (USA)

All in-stock orders placed before our daily cutoff are shipped the same day from within the United States.

Fast Domestic Delivery (1–3 Days)

We use expedited carriers to ensure your peptides arrive quickly and reliably nationwide.

Cold Chain Protection

Products are stored in industrial-grade freezers prior to shipment to maintain stability and purity.

Secure & Protective Packaging

Each order is carefully packed to protect against temperature fluctuations, moisture exposure, and physical damage during transit.

Real-Time Tracking

You’ll receive tracking information immediately upon shipment so you can monitor delivery progress.

Consistency You Can Rely On

No long international delays, no customs issues. Just fast, dependable delivery from a U.S.-based operation.

Storage Instructions:

All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.

Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.

Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.

Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.

However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
