The invention relates to NEP inhibitors for treating cardiovascular disorders. Preferred NEP inhibitors are compounds of formula (I) wherein R1 is C1–C6alkyl, C1–C6alkoxyC1–C3alkyl or C1–C6alkoxyC1–C6alkoxyC1–C3alkyl; R2 is hydrogen or C1–C6alkyl; L is a three atom linkage selected from —CH2—X—CH2— and —CH2—CH2—X— where the right hand side of the linkage is attached to R3 and where X is oxygen, sulfur or methylene; R3 is phenyl or aromatic heterocyclyl, either of which may be independently substituted by one or more groups selected from: C1–C6alkyl, halo, haloC1–C6alkyl, C1–C6alkoxy, haloC1–C6alkoxy, C1–C6alkylthio, haloC1–C6alkylthio and nitrile; and R4 and R5 are either both hydrogen, or one of R4 and R5 is hydrogen and the other is a biolabile ester-forming group that in the body of a patient is replaced by hydrogen.
