2A Biosciences is advancing novel serotonergic therapies to transform age-related and inflammatory disease treatments. We are developing first- and best-in-class small molecules that modify disease, beginning with neurodegenerative conditions of the eye and brain.
Our Mission
The Genesis of 2A Biosciences
In 2007, Dr. Charles Nichols made the pivotal discovery that certain serotonin 2A agonists, commonly known as psychedelics, can drive potent anti-inflammatory effects. Working alongside his father Dr. David Nichols, a pioneer whose research laid the foundation for modern psychedelic science and CNS therapeutics, the two uncovered how 2A receptor activation mediates anti-inflammatory and neuroplastic effects without inducing behavioral changes.
