example 1

[0295] (E) 3-(4-piperidinyl)oxyiminoandrostane-6,17-dione hydrochloride (I-aa)

[0296] A solution of androstane-3,6,17-trione (160 mg) in THF (3.2 mL) was added to 4-piperidinyloxyamine dihydrochloride (III-a, Preparation 1, 100 mg) and Na 2 HPO 4 12H 2 A solution of O (380 mg) in water (1.6 mL). After 2 hours at room temperature, NaCl (150 mg) was added and stirred for 15 minutes. The mixture was extracted with THF (2 x 2 mL), and the combined organic phases were washed with brine (3 x 3 mL), washed with Na 2 SO 4 Dry and evaporate to dryness. The residue was analyzed by flash column chromatography (SiO 2 , CH 2 Cl 2 :MeOH:NH3 9:1:0.1) purification. 5M HCl / EtOAc was added to the concentrated fraction. with Et 2 After O dilution, the solid was collected by filtration to afford the title compound I-aa (140 mg, 60%). 1 H-NMR (300MHz, DMSO-d 6 , ppm from TMS): δ 8.68 (2H, bb), 4.17 (1H, m), 3.15-2.90 (5H, m), 2.60-1.10 (23H, m), 0.79 (3H, s), 0.78 (3H, s).

example 2

[0298] (E, Z) 3-(3-azetidine)oxyiminoandrostane-6,17-dione fumarate (I-ab)

[0299] Following the procedure described in Example 1, starting from androstane-3,6,17-trione (950 mg) and 3-azetidinoxamine dihydrochloride (III-b, Preparation 2,500 mg), The title compound I-ab was obtained as a white solid (1.21 g, 80%). 1 H-NMR (300MHz, DMSO-d 6 , ppm from TMS): δ 6.50 (2H, s), 4.87 (1H, m), 4.10-2.90 (5H, m), 2.50-1.20 (19H, m), 0.79 (6H, s).

example 3

[0301] (E) 3-[3-(RS)-pyrrolidinyl]oxyiminoandrostane-6,17-dione hydrochloride (I-ac)

[0302] 3-(RS)-Pyrrolidinyloxyamine dihydrochloride (III-c, Preparation 3, 227 mg) was mixed with androstane-3,6,17-trione (495 mg) in THF:water (2 / 1 , 27 mL) solution was stirred for 30 minutes. NaCl was added and stirred until the two phases separated. After extracting the aqueous layer with THF, the combined organic phases were washed with brine, dried and evaporated. Flash column chromatography (SiO 2 , CH 2 Cl 2 :MeOH:NH 3 9:1:0.1) method for purification. To this concentrated fraction was added 5M HCl in EtOAc. with Et 2 After O dilution, the solid was collected by filtration to afford the title compound I-ac (464 mg, 60%). 1 H-NMR (300MHz, DMSO-d 6 , ppm from TMS): δ 9.59 (1H, bb), 9.41 (1H, bb), 4.74 (1H, m), 3.80-2.90 (5H, m), 2.60-1.20 (21H, m), 0.78 (6H, s).

Abstract

Compounds of formula (I), wherein the groups are as defined in the specification, are very useful for the preparation of medicaments for the treatment of cardiovascular disorders, especially heart failure and hypertension. These compounds are inhibitors of the enzymatic activity of Na+, K+-ATPases. They are very useful for the manufacture of medicaments for the treatment of diseases caused by the hypertensive effects of endogenous ouabain, such as progression of renal failure in autosomal dominant polycystic kidney disease (ADPKD), preeclamptic hypertension and protein Urine and renal failure progression in patients with adducin polymorphisms.

Description

technical field [0001] The present invention relates to novel 3-position azacyclic derivatives of 5- and / or 6- and / or 7-substituted androstane and androstene, a preparation process thereof, and compounds containing these derivatives for treating cardiovascular disorders Pharmaceutical compositions such as heart failure and hypertension. Background technique [0002] Cardiovascular disease remains the number one cause of morbidity and mortality in Western countries. Among them, hypertension and heart failure are two frequently occurring diseases. Hypertension is one of the most important cardiovascular risk factors, affecting more than a third of people over the age of 60. Congestive heart failure affects 1-2% of this group, and even 10% of the very elderly. This percentage is expected to increase (Sharpe, N. et al., The Lancet, 1998, 352 (Suppl. 1), 3-17). In addition, hypertension may be one of the most important causes of heart failure in the elderly (Eur. Heart J., 20...
