Abstract

Official abstract text for this publication.

The present application relates to novel substituted dihydropyrazolone derivatives, processes for their preparation, their use for treatment and/or prophylaxis of diseases and their use for the preparation of medicaments for treatment and/or prophylaxis of diseases, in particular cardiovascular and hematological diseases and kidney diseases, and for promoting wound healing.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for treatment of cardiovascular diseases, cardiac insufficiency, anemia, chronic kidney diseases and renal insufficiency in humans and animals using an active amount of at least one compound of formula I: in which R 1 represents a heteroaryl group of the formula wherein * denotes the linkage point with the dihydropyrazolone ring and R 4 denotes hydrogen, fluorine, chlorine, bromine, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxymethyl, (C 1 -C 4 )-alkoxy, trifluoromethoxy, hydroxycarbonyl or (C 1 -C 4 )-alkoxycarbonyl, R 2 represents a heteroaryl group of the formula wherein # denotes the linkage point with the dihydropyrazolone ring and R 6 , R 6A and R 6B are identical or different and independently of one another denote hydrogen or a substituent chosen from the group consisting of fluorine, chlorine, bromine, cyano, (C 1 -C 6 )-alkyl, trifluoro-methyl, hydroxyl, (C 1 -C 6 )-alkoxy, trifluoromethoxy, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, hydroxycarbonyl, (C 1 -C 4 )-alkoxycarbonyl, 4- to 6-membered heterocycloalkyl, phenyl and 5- or 6-membered heteroaryl, wherein (C 1 -C 6 )-alkyl in its turn can be substituted by hydroxyl, (C 1 -C 4 )-alkoxy or amino and 4- to 6-membered heterocycloalkyl, phenyl and 5- or 6-membered heteroaryl in their turn can in each case be substituted once or twice in an identical or different manner by fluorine, chlorine, bromine, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxyl, (C 1 -C 4 )-alkoxy, trifluoromethoxy, oxo, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, hydroxycarbonyl or (C 1 -C 4 )-alkoxy-carbonyl, and R 3 represents hydrogen, or a salt thereof. 2. The method of claim 1 , wherein R 1 represents a heteroaryl group of the formula wherein * denotes the linkage point with the dihydropyrazolone ring and R 4 denotes hydrogen, fluorine, chlorine, bromine, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxymethyl, (C 1 -C 4 )-alkoxy, trifluoromethoxy, hydroxycarbonyl or (C 1 -C 4 )-alkoxycarbonyl, R 2 represents a heteroaryl group of the formula wherein # denotes the linkage point with the dihydropyrazolone ring and R 6 , R 6A and R 6B are identical or different and independently of one another denote hydrogen or a substituent chosen from the series consisting of fluorine, chlorine, bromine, cyano, (C 1 -C 6 )-alkyl, trifluoro-methyl, hydroxyl, (C 1 -C 6 )-alkoxy, trifluoromethoxy, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, hydroxycarbonyl, (C 1 -C 4 )-alkoxycarbonyl, 4- to 6-membered heterocycloalkyl, phenyl and 5- or 6-membered heteroaryl, wherein (C 1 -C 6 )-alkyl in its turn can be substituted by hydroxyl, (C 1 -C 4 ) -alkoxy or amino and 4- to 6-membered heterocycloalkyl, phenyl and 5- or 6-membered heteroaryl in their turn can in each case be substituted once or twice in an identical or different manner by fluorine, chlorine, bromine, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxyl, (C 1 -C 4 )-alkoxy, trifluoromethoxy, oxo, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, hydroxycarbonyl and/or (C 1 -C 4 )-alkoxy-carbonyl, and R 3 represents hydrogen, or a salt thereof. 3. The method of claim 1 , wherein R 1 represents a heteroaryl group of the formula wherein denotes the linkage point with the dihydropyrazolone ring and R 4 denotes hydrogen, fluorine, chlorine, bromine, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxymethyl, (C 1 -C 4 )-alkoxy, trifluoromethoxy, hydroxycarbonyl or (C 1 -C 4 )-alkoxycarbonyl, R 2 represents a heteroaryl group of the formula wherein # denotes the linkage point with the dihydropyrazolone ring and R 6 denotes hydrogen or a substituent chosen from the series consisting of fluorine, chlorine, bromine, cyano, (C 1 -C 6 )-alkyl, trifluoro-methyl, hydroxyl, (C 1 -C 6 )-alkoxy, trifluoromethoxy, amino, mono-(C 1 -C 4 ) -alkylamino, di-(C 1 -C 4 )-alkylamino, hydroxycarbonyl, (C 1 -C 4 )-alkoxycarbonyl, 4- to 6-membered heterocycloalkyl, phenyl and 5- or 6-membered heteroaryl, wherein (C 1 -C 6 )-alkyl in its turn can be substituted by hydroxyl, (C 1 -C 4 ) -alkoxy or amino and 4- to 6-membered heterocycloalkyl, phenyl and 5- or 6-membered heteroaryl in their turn can in each case be substituted once or twice in an identical or different manner by fluorine, chlorine, bromine, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxyl, (C 1 -C 4 )-alkoxy, trifluoromethoxy, oxo, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, hydroxycarbonyl and/or (C 1 -C4)-alkoxy-carbonyl, and R 3 represents hydrogen, or a salt thereof. 4. The method of claim 1 , wherein, R 1 represents a heteroaryl group of the formula wherein * denotes the linkage point with the dihydropyrazolone ring and R 4 denotes hydrogen, fluorine, chlorine, bromine, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxymethyl, (C 1 -C 4 )-alkoxy, trifluoromethoxy, hydroxycarbonyl or (C 1 -C 4 )-alkoxycarbonyl, R 2 represents a heteroaryl group of the formula wherein # denotes the linkage point with the dihydropyrazolone ring and R 6 denotes hydrogen or a substituent chosen from the series consisting of fluorine, chlorine, bromine, cyano, (C 1 -C 6 )-alkyl, trifluoro-methyl, hydroxyl, (C 1 -C 6 )-alkoxy, trifluoromethoxy, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, hydroxycarbonyl, (C 1 -C 4 )-alkoxycarbonyl, 4- to 6-membered heterocycloalkyl, phenyl and 5- or 6-membered heteroaryl, wherein (C 1 -C 6 )-alkyl in its turn can be substituted by hydroxyl, (C 1 -C 4 )-alkoxy or amino and 4- to 6-membered heterocycloalkyl, phenyl and 5- or 6-membered heteroaryl in their turn can in each case be substituted once or twice in an identical or different manner by fluorine, chlorine, bromine, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxyl, (C 1 -C 4 )-alkoxy, trifluoromethoxy, oxo, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, hydroxycarbonyl and/or (C 1 -C 4 )-alkoxy-carbonyl, and R 3 represents hydrogen, or a salt thereof. 5. A method for treatment of cardiovascular diseases, cardiac insufficiency, anemia, chronic kidney diseases and renal insufficiency comprising administering to a human o
