P1-185 ,also known asprogesterone 3-O -(L -valine)-E -oxime or aspregn-4-ene-3,20-dione 3-O -(L -valine)-E -oxime ,is asynthetic progestogen andneurosteroid and anoxime ester analogue andprodrug ofprogesterone (and by extension ofallopregnanolone ).[1] [2] It was developed as an improvedwater-soluble version of progesterone such that it could be formulated as anaqueous preparation and easily and rapidly administeredintravenously as a potential therapy fortraumatic brain injury .[1] [2] However, thechemical synthesis of P1-185 was described as somewhat challenging, so oxime conjugates of progesterone of the C20 instead of C3 position, such asEIDD-1723 andEIDD-036 ,have since been developed.[2] [3] [4]
