Abstract
The invention relates to a novel use of benzazepine, benzoxazepine, benzothiazepine-N-acetic acid and phosphono-substituted benzazepinone derivatives having both neutral endopeptidase (NEP) and/or human soluble endopeptidase (hSEP), and endothelin convertase (ECE), inhibitory activity. The compounds of this invention are useful for the preparation of pharmaceutical compositions to reduce harmful effects of symptomless progressive disseminated perfusion deficiency of organs, or parts thereof, that may be suggestive of systemic diseases.
Claims20
A method of treating perfusion deficiency of an organ or part thereof in a human subject as measured by an elevated concentration of a biomarker in one or more bodily fluids wherein the organ is the brain or part thereof, comprising administering a therapeutically effective amount of a compound of the general formula (4):
- wherein A is CH2,
- wherein R2 and R3 independently represent hydrogen;
- R4 and R6 independently represent hydrogen or a group that forms a biolabile carboxylic ester;
- and R5 is selected from the group consisting of -alkyl-(C1-C6)-phenyl, and -alkyl-(C1-C6)-naphthyl,
- or a pharmaceutically acceptable salt or stereoisomer thereof;
- wherein the biomarker is selected from the group consisting of Endothelin-1 biomarker, pre-Endothelin-1, Pro-Endothelin (Big Endothelin-1), endothelin-1 converting enzyme (ECE-1), neutral endopeptidase (NEP), human soluble endopeptidase (hSEP), and combinations thereof.
A method of preventing perfusion deficiency of an organ or part thereof in a human subject wherein the organ is the brain or part thereof, comprising administering a therapeutically effective amount of a compound of the general formula (4):
- wherein A is CH2,
- wherein R2 and R3 independently represent hydrogen;
- R4 and R6 independently represent hydrogen or a group that forms a biolabile carboxylic ester;
- and R5 is selected from the group consisting of -alkyl-(C1-C6)-phenyl, and -alkyl-(C1-C6)-naphthyl,
- or a pharmaceutically acceptable salt or stereoisomer thereof;
- wherein the prevention of the perfusion deficiency is confirmed by measuring the presence or absence of an elevated concentration of a biomarker in one or more bodily fluids wherein the biomarker is selected from the group consisting of Endothelin-1 biomarker, pre-Endothelin-1, Pro-Endothelin (Big Endothelin-1), endothelin-1 converting enzyme (ECE-1), neutral endopeptidase (NEP), and human soluble endopeptidase (hSEP), and combinations thereof.
