PDE1-IN-2 is a PDE1 inhibitor extracted from patent WO2016/55618 A1, example 31. PDE1-IN-2 has IC 50 values of 6 nM, 140 nM and 164 nM for PDE1C, PDE1B and PDE1A, respectvely. PDE1-IN-2 is developed for the research of neurodegenerative disorders and psychiatric disorders In Vitro PDE1 enzymes are expressed in the central nervous system (CNS), making this gene family an attractive source of new targets for the treatment of psychiatric and neurodegenerative disorders. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:PDE1A 164 nM (IC 50 ) PDE1B 140 nM (IC 50 ) PDE1C 6 nM (IC 50 )
