GlossaryAllopregnanolone (THP)

neurosteroid derived from progesterone that modulates brain activity

Allopregnanolone, also known as 3α-hydroxy-5α-pregnan-20-one, is a neurosteroid derived from progesterone. It plays a crucial role in modulating the brain's response to stress and anxiety by enhancing the activity of GABA, the primary inhibitory neurotransmitter. This compound is also being studied for its potential therapeutic effects in conditions like depression, anxiety disorders, and certain neurodegenerative diseases.
