Phenotype-first longevity therapeutics

Turning AI-discovered, lifespan-extending HITs into medicines for age-related diseases.

SYDRA discovers small molecules through whole-organism lifespan biology, then advances the strongest phenotypes toward human targets, mechanisms and disease medicines.

01 / PIPELINE

Two discovery engines.
One path to medicine.

AI-selected, phenotype-proven programs and a new generative cohort move through one evidence-gated path. Only experimental lifespan HITs graduate into therapeutic programs.

02 / THE PARADIGM

We start with what works—
not with what should work.

Most drug discovery begins with a target and asks whether a molecule works. SYDRA begins with a lifespan phenotype, then discovers why it works and where it can become a medicine.

Start with an organism-level result. Decode the biology that made it work.

03 / EVIDENCE

From six million structures
to five lifespan HITs.

In early 2023, SYDRA completed its first million-scale AI-to-organism longevity discovery campaign.

Demonstrated

C. elegans lifespan

AI predictions become meaningful only when they survive contact with living biology. Our C. elegans platform identifies molecules with measurable lifespan-extending activity and prioritizes the strongest phenotypes for further development.

Pilot signal

Late-life mammalian pilot

Encouraging remaining-lifespan trends emerged after treatment began in naturally aged mice. Confirmatory development is planned.

Initiation underway

Target deconvolution & MoA elucidation in human cells

Human-cell target and mechanism-of-action program initiation is underway for the lead programs.

04 / TECHNOLOGY

Chemical imagination.
Geroprotector judgment.
Medicinal refinement.

SYDRA separates the model that generates novel chemistry from the discriminator that ranks geroprotective potential, then refines prioritized structures for synthesis.

01Data Depth

Locate

A machine-learning method based on robust statistics identifies geroprotector-enriched neighborhoods in molecular representation space and derives molecular seeds.

02DepreSMILEr · 1.7B

Generate

Our proprietary chemical foundation SLM completes those seeds into novel, syntactically valid and chemically plausible structures.

03Gero-ANN · proprietary discriminator

Judge

At the heart of both discovery engines is Gero-ANN, SYDRA’s proprietary artificial neural network for ranking both generated and existing molecules by predicted geroprotective potential. Generated structures first pass through RDKit chemical filters before entering Gero-ANN; existing molecules enter it directly.

04Molecular optimization & medicinal chemistry

Refine

Ranked structures enter a scientist-guided design loop. Computational chemistry helps us explore analogues and prioritize designs that balance drug-likeness, chemical stability, synthetic feasibility and structural liability risk before synthesis.

Their next decisive test will not be another simulation. It will be biology.

THE SYDRA LOOP

A molecule enters SYDRA as a prediction. A living organism decides whether it matters. Human biology reveals how it can become a medicine.
