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 of treatment of a cardiovascular disease, cardiac insufficiency, anemia, a chronic kidney disease or renal insufficiency comprising administering to a human or animal in need thereof an active amount of a 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 series consisting of fluorine, chlorine, bromine, cyano, (C 1 -C 6 )-alkyl, trifluoromethyl, 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 and 4- to 6-membered heterocycloalkyl, 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 in its turn can be substituted once or twice in an identical or different manner by fluorine, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxyl, (C 1 -C 4 )-alkoxy, oxo, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, hydroxycarbonyl and/or (C 1 -C 4 )-alkoxycarbonyl, and R 3 represents hydrogen, and their salts, solvates and solvates of the salts. 2. The method of treatment of claim 1 , wherein the compound of formula (I) is 2-[5-(Hydroxymethyl)pyridin-2-yl]-4-[4-(trifluoromethyl)-1H-imidazol-1-yl]-1,2-dihydro-3H-pyrazol-3-one having the following formula and its salts, solvates and solvates of the salts.
