A New Era of Disease Modification

Harnessing Serotonin Biology to Reverse Eye and Brain Degeneration

Precision Serotonergic Therapies for Regeneration and Protection

2A Biosciences pioneers life-changing therapies for the 400M+ people globally suffering from degenerative eye and brain diseases. Our proprietary small molecules activate serotonin 2A receptors to unlock regenerative, anti-inflammatory, and neuroprotective outcomes through precise molecular designs.

Targeting Root Causes of Neuro-degeneration

Serotonin 2A receptors - long misunderstood as purely psychotropic - are now known to be powerful modulators of inflammation and regeneration.

Our serotonergics are the first to systematically harness this biology to treat neurodegeneration, addressing root disease causes like mitochondrial dysfunction, oxidative stress, and inflammation, while simultaneously promoting neuronal growth and plasticity.

Our lead program is on track to enter Phase 2a trials.
