EIDD-1723
EIDD-1723, also known as EPRX-01723 or as progesterone 20E-oxime] sodium salt, is a synthetic, water-soluble analogue of progesterone and a neurosteroid which was developed for the potential treatment of traumatic brain injury. It is a rapidly converted prodrug of EIDD-036, which is considered to be the active form of the agent. Previous C3 and C20 oxime derivatives of progesterone, such as P1-185, were also developed and studied prior to EIDD-1723.
