POWERING PRECISION MEDICINE

Accelerating precision medicine through AI-powered peptide design and nanoparticle targeting technology

Our Mission

At Ligandal, we believe precision is the key to unlocking cures. Our platform delivers therapeutics to the exact molecular locations of disease, transforming treatments from managing symptoms to addressing root causes with atomic accuracy.

We enable targeted medicine delivery and addressing the precise cause of disease at its root, making a new generation of medicine possible.

Our Vision

A world where disease is no longer a limitation to human potential, where precision medicine targets the molecular roots of disease to unlock cures previously thought impossible.

Our Mission

To solve delivery - the final frontier of medicine. We make medicine precise, personalized, and predictive. We enable cures and make diagnostic-responsive medicine the paradigm.

Our Promise

To transform medicine through breakthrough, enabling technology that enhances targeting specificity, selectivity, and cellular internalization 10x beyond current standards.

Our Story

Andre Watson, Founder

A Mission Born from Scientific Vision

Ligandal was founded on a simple yet powerful principle: everyone deserves medicine that works at the molecular root of their disease. Andre Watson, our founder and CEO, established Ligandal with a vision for precision medicine targeting that allows for diseases to be approached at their molecular roots, with the aim of improving patient outcomes through accelerated translation of insights into cures.

Witnessing firsthand how years are lost to ineffective treatments and trial-and-error approaches, we set out to create technology that would fundamentally change how diseases are targeted and treated.

Today, our PDC (Peptide Direct Conjugate) technology, driven by LigandAI™ and Predictive Interactomics, represents the culmination of over 10 years of R&D directed towards that vision—precision medicine that targets disease at its molecular roots with unprecedented accuracy and efficiency.

"For decades, the industry has been constrained by imprecise drugs and an inability to guide our most advanced therapeutics to the disease sites that matter. Ligandal is building the enabling technology layer—a Delivery OS for precision medicine—that guides your therapies exactly where they need to go. This is the infrastructure that unlocks next-generation, molecularly and genomically precise therapeutics."

This unified approach enables truly preventative, personalized, and predictive medicine.

Receptor Targeting Technology

Receptor Targeting Technology

Our PDC technology targets specific receptors with atomic precision. Using custom-designed peptides with optimized binding properties, we deliver therapeutic payloads directly to cells in the precise physiological locations of disease.

How Receptor Targeting Works

  • Specificity: Our peptides are designed to bind only to specific receptors in the exact locations where treatment is needed
  • Affinity: Modular and predictive binding affinity ensures enhanced targeting precision
  • Selectivity: Minimal binding to off-target receptors reduces side effects
  • Customization: Our platform can target virtually any receptor with custom-designed peptides

Using computational design and screening, we identify peptide sequences that bind targets with unprecedented precision. This approach enables targeting of previously "undruggable" disease pathways.

Cellular Delivery Process

Cellular Delivery Process

Our PDC technology targets specific receptors on cell surfaces in the precise physiological locations of disease. The peptide-directed particles enter cells through receptor-mediated endocytosis, delivering therapeutic payloads to their intended targets. This approach improves efficacy while reducing off-target effects.

Delivery Process Steps

  1. Targeting: PDCs bind specifically to receptors in the precise locations where treatment is needed
  2. Internalization: Receptor-mediated endocytosis draws PDCs into the cell
  3. Endosomal Escape: Specialized mechanisms release the therapeutic payload into the cytoplasm or nucleus
  4. Therapeutic Action: Payloads reach their intracellular targets for maximum efficacy

This multi-step process ensures therapeutics not only reach the right cells but also maintain their activity once inside. Our technology is payload-agnostic and can deliver mRNA, DNA, CRISPR, and other gene editing technologies.

PDC Technology Key Benefits

Our peptide-directed conjugate (PDC) technology delivers therapeutic payloads with precision and efficiency.

Precise Targeting

PDC peptides recognize and bind to specific cellular receptors with high affinity and selectivity, ensuring targeted delivery to disease sites.

Efficient Internalization

Once bound, PDCs trigger receptor-mediated endocytosis for efficient cellular internalization, enhancing therapeutic delivery.

Payload Flexibility

Our technology is payload-agnostic, compatible with mRNA, DNA, CRISPR, and other gene editing technologies for versatile therapeutic applications.
