New secondary amines
The invention relates to novel compounds of the formula (I). The invention also concerns related aspects including processes for the preparation of the compounds, pharmaceutical compositions containing one or more compounds of formula (I) and especially their use as renin inhibitors in cardiovascular events and renal insufficiency.
In the renin-angiotensin system (RAS) the biologically active angiotensin II (Ang II) is generated by a two-step mechanism. The highly specific enzyme renin cleaves angiotensinogen to angiotensin I (Ang I), which is then further processed to Ang II by the less specific angiotensin-converting enzyme (ACE). Ang II is known to work on at least two receptor subtypes called AT] and AT2. Whereas AT] seems to transmit most of the known functions of Ang II, the role of AT2 is still unknown.
Modulation of the RAS represents a major advance in the treatment of cardiovascular diseases. ACE inhibitors and AT] blockers have been accepted to treat hypertension (Waeber B. et al, "The renin-angiotensin system: role in experimental and human hypertension", in Birkenhager W. H.. Reid J. L. (eds): Hypertension, Amsterdam, Elsevier Science Publishing Co, 1986. 489-519; Weber M. A., Am. J. Hypertens., 1992. 5, 247S). In addition, ACE inhibitors are used for renal protection (Rosenberg M. E. el al. Kidney International 1994. 45. 403; Breyer J. A. et al.. Kidney International 1994. 45, SI56), in the prevention of congestive heart failure (Vaughan D. E. et al.. Cardiovasc. Res., 1994, 28, 159; Fouad-Tarazi F. el al. Am. J. Med., 1988, 84 (Suppl. 3A), 83) and myocardial infarction (Pfeffer M. A. el al., N. Engl. J. Med., 1992, 327, 669).
The rationale to develop renin inhibitors is the specificity of renin (Kleinert H. D., Cardiovasc. Drugs, 1995, 9, 645). The only substrate known for renin is angiotensinogen, which can only be processed (under physiological conditions) by renin. In contrast, ACE can also cleave bradykinin besides Ang I and can be by-passed by chymase, a serine protease (Husain A., ./. Hyperlens., 1993, //. 1155). In patients inhibition of ACE thus leads to bradykinin accumulation causing cough (5-20%) and potentially life-threatening angioneurotic edema (0.1-0.2%) (Israili Z. H. el al. Annals of Internal Medicine, 1992, III, 234). ACE inhibitors do not inhibit Chymase. Therefore, the formation of Ang II is

still possible in patients treated with ACE inhibitors. Blockade of the AT] receptor (e.g. by losartan) on the other hand overexposes other AT-receptor subtypes (e.g. AT2) to Ang II, whose concentration is significantly increased by the blockade of AT] receptors. In summary, renin inhibitors are expected to demonstrate a different pharmaceutical profile than ACE inhibitors and AT] blockers with regard to efficacy in blocking the RAS and in safety aspects.
Only limited clinical experience (Azizi M. el al, J. Hyper/ens., 1994, 12, 419; Neutel .1. M. el al. Am. Heart, 1991. 722, 1094) has been created with renin inhibitors because of their insufficient oral activity due to their peptidomimetic character (Kleinert H. D., Cardiovasc. Drugs, 1995, 9, 645). The clinical development of several compounds has been stopped because of this problem together with the high cost of goods. Only one compound containing four chiral centers has entered clinical trials (Rahuel J. et al, Chem. Biol., 2000, 7, 493; Mealy N. E., Drugs of the Future, 2001, 26, 1139). Thus, renin inhibitors with good oral bioavailability and long duration of action are required. Recently, the first non-peptide renin inhibitors were described which show high in vitro activity (Oefner C. et al, Chem. Biol., 1999, 6, 127; Patent Application WO 97/09311; Marki H. P. el al., 11 Farmaco, 2001. 56, 21). However, the development status of these compounds is not known.
The present invention relates to renin inhibitors of a non-peptidic nature and of low molecular weight. Described are orally active renin inhibitors of formula (I) which have a long duration of action and which are active in indications beyond blood pressure regulation where the tissular renin-chymase system may be activated leading to pathophysiologically altered local functions such as renal, cardiac and vascular remodelling, atherosclerosis, and possibly restenosis. So, the present invention describes these non-peptidic renin inhibitors of formula (I).
In particular, the present invention relates to novel compounds of the formula (I)

and salts of these compounds.
The compounds of formula (I) are useful for the treatment and/or prophylaxis of diseases such as or related to hypertension, congestive heart failure, pulmonary hypertension, renal insufficiency, renal ischemia, renal failure, renal fibrosis, cardiac insufficiency, cardiac hypertrophy, cardiac fibrosis, myocardial ischemia, cardiomyopathy, glomerulonephritis, renal colic, complications resulting from diabetes such as nephropathy, vasculopathy and neuropathy, glaucoma, elevated intra-ocular pressure, atherosclerosis, restenosis post angioplasty, complications following vascular or cardiac surgery, erectile dysfunction, hyperaldosteronism, lung fibrosis, scleroderma, anxiety, cognitive disorders, complications of treatments with immunosuppressive agents, and other diseases related to the renin-angiotensin system.
The compounds of formula (I) are especially useful for the treatment and/or prophylaxis of hypertension, congestive heart failure, pulmonary hypertension, renal insufficiency, renal ischemia, renal failure, renal fibrosis, cardiac insufficiency, cardiac hypertrophy, cardiac fibrosis, myocardial ischemia, cardiomyopathy, complications resulting from diabetes such as nephropathy, vasculopathy and neuropathy.
In one embodiment, the invention relates to a method for the treatment and/or prophylaxis of diseases, which are associated with a dysregulation of the renin-angiotensin system, in particular to a method for the treatment and/or prophylaxis of the above-mentioned diseases, said methods comprising administering to a patient a pharmaceutically active amount of a compound of formula (I).
A further aspect of the present invention relates to pharmaceutical compositions comprising a compound of formula (I) and a pharmaceutically acceptable carrier material. These pharmaceutical compositions may be used for the treatment and/or prophylaxis of the above-mentioned diseases. The pharmaceutical compositions can be used for enteral.

parenteral, or topical administration. They can be administered, for example, perorally, e.g. in the form of tablets, coated tablets, dragees, hard and soft gelatine capsules, solutions, emulsions or suspensions, rectally. e.g. in the form of suppositories, parenterally, e.g. in the form of injection solutions or infusion solutions, or topically, e.g. in the form of ointments, creams or oils.
The invention also relates to the use of a compound of formula (I) for the preparation of pharmaceutical compositions for the treatment and/or prophylaxis of the above-mentioned
diseases.
The production of the pharmaceutical compositions can be effected in a manner which will be familiar to any person skilled in the art (see for example Mark Gibson, Editor, Pharmaceutical Preformulation and Formulation, IHS Health Group, Englewood, CO, USA, 2001; Remington, The Science and Practice of Pharmacy, 20th Edition, Philadelphia College of Pharmacy and Science) by bringing the described compounds of formula (I) or their pharmaceutically acceptable salts, optionally in combination with other therapeutically valuable substances, into a galenical administration form together with suitable, non-toxic, inert, therapeutically compatible solid or liquid carrier materials and, if desired, usual pharmaceutical adjuvants.
Compounds of formula (I) or the above-mentioned pharmaceutical compositions are also of use in combination with other pharmacologically active compounds such as ACE-inhibitors, neutral endopeptidase inhibitors, aldosterone antagonists, angiotensin II receptor antagonists, endothelin receptors antagonists, vasodilators, calcium antagonists, potassium activators, diuretics, sympatholitics, beta-adrenergic antagonists, alpha-adrenergic antagonists, 1 lbeta-hydroxysteroid dehydrogenase type 1 inhibitors, soluble guanylate cyclase activators and/or other drugs beneficial for the prevention or the treatment of the above-mentioned diseases.
The present invention also relates to pro-drugs of a compound of formula (I) that convert in vivo to the compound of formula (I) as such. Any reference to a compound of formula (I) is

therefore to be understood as referring also to the corresponding pro-drugs of the compound of formula (I), as appropriate and expedient.
The compounds of formula (1) can be manufactured by the methods outlined below, by the methods described in the examples or by analogous methods.
A compound of type A as depicted in Scheme 1 can be prepared as described in the patent applications WO 2003/093267. WO 2004/002957, WO 2004/096769, WO 2004/096803, WO 2004/096799. and WO 2004/096366. PG stands for a suitable protecting group, typically a carbamate. Ra stands for a suitable ester substituent, typically a methyl, an ethyl, or a benzyl group. L' stands for a precursor of the L-group as defined for formula (I). Generally, the main chain of the L-substituent is already completed in the L'-group, but the R> and R6-groups have to be built in later on. The Ra- and L/-groups can be modified along the synthesis. A coupling catalysed by a transition metal, typically palladium, more commonly a Negishi or a Suzuki coupling, leads to a compound of type B, wherein VH stands for a precursor of the V-substituent as defined for formula (I). Va can be modified along the synthesis. Completion of the U-V-fragment leads to a compound of type C. Sometimes it is possible to build in the full U-V-W-fragment from a compound of type A, yielding a compound of type C directly. Reduction of the double bond on a compound of type C, followed by equilibrating conditions, leads to a compound of type D, wherein the U-V-W- and RaOCO-substituents are often trans to each others. If n = 1, two diastereoisomers are obtained; they can be separated by chromatographic methodologies. Sometimes it is more convenient to reduce the double bond on a compound of type C; in this case a compound of type E is obtained, which is transformed into a compound of type D after achievement of the U-V-W-substituent.
Scheme 1


The U-V-W- or Va-W-fragments that are coupled to a compound of type A have to be prepared separately. The preparation of several such substituents is described in the patent applications mentioned earlier. Otherwise a pyrrolidine substituent can be attached to an aromatic ring by a copper- or palladium-catalysed coupling as described in Scheme 2. Under certain circumstances a transition metal is not necessary to catalyse this reaction. A compound of type F, wherein PG* stands for a suitable protecting group, will be transformed into a compound of type G. wherein X' stands for CH or N. If W in formula (I) represents a thiazolyl, the same chemistry can be applied as well.

If V represents -O-CH2-Q-, the isoxazolyl moiety is prepared by cycloaddition. This cycloaddition can be realized on the W-Va-fragment in a compound of type B, leading to a compound of type C as described in Scheme 1. Otherwise the cycloaddition can be performed separately as, for instance, described in Scheme 3. Cycloaddition on a

compound of type H with an often commercially available aldehyde leads to a compound of type J. Of course an aldehyde moiety can be built on the W-V-fragment, and a compound of the form U-CCH can be constructed, to give after cycloaddition. another isoxazolyl moiety. The same principles can be used to prepare oxadiazolyl moieties, using methodologies described in the literature.
Scheme 3

Also a hydroxymethyl isoxazole (Scheme 4) can be prepared from the aldehyde mentioned in Scheme 3 and propargyl alcohol. Coupling to a phenyl or heteroaryl derivative, wherein X" typically stands for -OH, -Br, or -I, leads to a compound of type J.

The ester group of a compound of type C or D can be cleaved to yield a compound of type K. as described in Scheme 5. If a double bond is present, it can partially migrate and a mixture of two isomeric carboxylic acids is obtained. This mixture is not separated. An amide coupling on a compound of type K yields a compound of type L. If a mixture of

isomers with the double bond in the 3.4- or in the 4.5-positions is obtained, this mixture is separated on this stage by chromatographic methodologies.

The amines used for such amide couplings have to be prepared separately, as described specifically in the examples, vide infra.
Final construction of the L-group, if necessary, leads to a compound of type M, as described in Scheme 6. Final removal of the protecting group PG leads to a compound of formula (I).

Enantiomerically pure compounds can always be obtained by chromatographic separation of the corresponding racemate. using a chiral solid support. Enantioselective synthesis of several systems are known as well in the literature (Murthy, K. S. K., Rey, A. W., Tjepkema, M., Tetrahedron Lett., 2003. 44. 5355; Cossy. J., Mirguet, O., Pardo, Domingo G., Desmurs, J.-R., European J. Org. Chem., 2002, 21, 3543; Carroll, F. I.,- Runyon, S. P.,

Biological Assays
1. Enzyme immuno assay (EIA) to estimate Angl accumulation and renin inhibition
1.1 Preparation of Angl-BSA conjugate
1.3 mg (1 u-mol) of Angl [1-10 (Bachem, H-1680)] and 17 mg (0.26 u.mol) of BSA (Fluka, 05475) were dissolved in 4 mL of 0.1 M phosphate buffer, pH 7.4, after which 2 mL of a 1:100 dilution of glutaraldehyde in H20 (Sigma G-5882) was added dropwise. The mixture was incubated overnight at 4 °C. then dialyzed against 2 liters of 0.9% NaCl, twice for 4 h at rt, followed by dialysis against 2 liters of PBS IX overnight at rt. The solution was then filtered with a Syringe filter, 0.45 urn (Nalgene, Cat. No. 194-2545). The conjugate can be stored in polypropylene tubes in 0.05% sodium azide at 4 °C for at least 12 months.
1.2 Preparation of BSA-AngI coated MTP
Microtiter plates (MPT384, MaxiSorp™, Nunc) were incubated overnight at 4 °C with 80 ul of Angl (1-10)/BSA conjugate, diluted LIOO'OOO in PBS IX in a teflon beaker (exact dilution dependent on batch of conjugate), emptied, filled with 90 ul of blocking solution

[0.5% BSA (Sigma A-2153) in PBS IX, 0,02% NaN3], and incubated for at least 2 h at it, or overnight at 4 °C. 96 well MTP (MaxiSorp™, Nunc) were coated with 200 ul conjugate and blocked with 250 ul blocking solution as above, except that the blocking solution contained 3% BSA. The plates can be stored in blocking solution at 4 °C for 1 month.
1.3 Angl-EIA in 384 well MTP
The AngI (1-10)/BSA coated MTP were washed 3 times with wash buffer (PBS IX, 0.01% Tween 20) and filled with 75 u) of primary antibody solution (anti-Angl antiserum, pre¬dicted 1:10 in horse serum), diluted to a final concentration of 1:100'000 in assay buffer (PBS IX. ImM EDTA, 0.1% BSA, pH 7.4). 5 ul of the renin reaction (or standards in assay buffer) (see below) were added to the primary antibody solution and the plates were incubated overnight at 4 °C. After the incubation the plates were washed 3 times with wash buffer and incubated with secondary antibody [anti-rabbit IgG, linked to horseradish peroxidase (Amersham Bioscience, NA 934V). diluted 1 ^'OOO in wash buffer] for 2 h at rt. The plates were washed 3 times with wash buffer and then incubated for 1 h at rt with substrate solution [1.89mM ABTS (2.2'-azino-di-(3-ethyl-benzthiazolinsulfonate)] (Roche Diagnostics, 102 946) and 2.36mM H202 [30%, (Fluka, 95300] in substrate buffer (0.1M sodium acetate, 0.05M sodium dihydrogen phosphate, pH 4.2). The OD of the plate was read at 405 nm in a microplate reader (FLUOStar Optima from BMG). The production of AngI during the renin reaction was quantified by comparing the OD of the sample with the OD of a standard curve of Angl(l-lO), measured in parallel.
2. Primary renin inhibition assay: IQo in buffer, 384 well MTP
The renin assay was adapted from an assay described before (Fischli W. el al, Hypertension, 1991, 18:22-31) and consists of two steps: in the first step, recombinant human renin is incubated with its substrate (commercial human tetradecapeptide renin substrate) to create the product Angiotensin I (AngI). In the second step, the accumulated AngI is measured by an immunological assay (enzyme immuno assay, EIA). The detailed description of this assay is found below. The EIA is very sensitive and well suited for renin activity measurements in buffer or in plasma. Due to the low concentration of renin used in this assay (2 fmol per assay tube or 10 pM) it is possible to measure inhibitor affinities in this primary assay down to low pM concentration.

2.1 Methodology
Recombinant human renin (3 pg/u.1) in assay buffer (PBS IX, ImM EDTA, 0.1% BSA, pH 7.4), human tetradecapeptide (1-14) substrate (Bachem, M-1120) [5 uM in 10 mM HC1], hydroxyquinoline sulfate (Fluka. 55100) [30 mM in H20] and assay buffer were premixed at 4 °C at a ratio of 100:30:10:145. 47.5 ul per well of this premix was transferred into polypropylene plates (MTP384, Nunc). Test compounds were dissolved and diluted in 100% DMSO and 2.5 u] added to the premix, then incubated at 37 °C for 3 h. At the end of the incubation period, 5 ul of the renin reaction (or standards in assay buffer) were transferred into E1A assays (as described above) and Angl produced by renin was quantified. The percentage of renin inhibition (Angl decrease) was calculated for each concentration of compound and the concentration of renin inhibition was determined that inhibited the enzyme activity by 50% (IC50). The compounds of the present invention also exhibit a very good bioavailability and are metabolically more stable than prior art compounds.
