Description

PIPERIDINE DERIVATIVES AS RENIN INHIBITORS FOR THE TREATMENT OF HYPERTENSION

FIELD OF THE^'INNENTION

This invention relates tυ piperidine derivative useful as inhibitors of renin.

BACKGROUND OF THE INVENTION

^" Renin is an endopeptidase (molecular weight about 40,000) produced and secreted by the juxtaglomerular cells of the kidney, which cleaves the naturally-occurring plasma glycoprotein; antiotensinogen. Renin cleaves angiotensinogen, its protein substrate, to split off the hemodynamically-inactive N-terminal decapeptide, angiotensin I, which is converted in the lungs, kidney or other tissue by angiotensin-converting enzyme to the potent pressor octapeptide, angiotensin II. Angiotensin LI is known to be a potent pressor substance, i.e., a substance that is capable of inducing a significant increase in blood pressure, and is believed to¹-¹ act by causing the constriction of blood vessels and the release of the sodium-retaining hormone aldosterone from the adrenal gland. Thus, the renin-angiotensinogen system has been implicated as a causative factor in hypertension congestive heart failure, end organ failure, stroke, myocardia infarction, glaucoma and hyperaldosteronism.

Inhibitors of angiotensin I converting enzyme have proven useful in the modulation of the renin-angiotensin system. Consequently, specific inhibitors of the limiting enzymatic step ^"that ultimately regulates angiotensin II production, the action of renin on its substrate, are sought as effective therapeutic agents in the treatment of hypertension, and congestive heart failure.

I, Formula II or pharmaceutically acceptable salts thereof that eliminates, alleviates, inhibits the progression of, or reverses progression of, in part or in whole, any one or more of the pathological hallmarks or symptoms of any one of the diseases and disorders being treated. including, but not limited to, hypertension, congestive heart failure, stroke, myocardial infarction, glaucoma, and hyperaldosteronism.

The term "preventing-' as used herein refers to the prophylactic administration of a compound of Formula I, Formula II or pharmaceutically acceptable salts thereof to an

5 asymptomatic patient at risk for the disease or disorder being prevented to inhibit the onset of an associated pathological hallmark or symptom, including, but not limited to, hypertension, congestive heart failure, stroke, myocardial infarction, glaucoma, and hyperaldosteronism.

_ Additionally, once the onset of a pathological hallmark or symptom has begun, preventing means the prevention of further progression or reversal of progression, in part or in whole, of the

10 pathological hallmark or symptom.

The tenn "pharmaceutically acceptable salts, esters, amides,- and.prodrugs" as used herein refers to those carboxylate salts, amino acid addition salts, esters, amides, and prodrugs of. the compounds of the present invention which are, within the scope of sound medical judgment,

'• suitable for use in contact with the tissues of.patients without undue toxicity, irritation; allergic

15_ response, and the like, commensurate with a reasonable benefit/risk ratio, and effective^" for their -

^• intended use,. as well as the zwitterionic forn s, where possible, of the compounds of the- invention. The term "salts" refers to the relatively non-toxic, inorganic and organic acid addition .

• salts of compounds of the present invention. These salts can be prepared in situ during the final ^{< •} i - isolation and purification of the compounds or by separately reacting the purified compound in

• 20 its free base form with a suitable organic or inorganic acid and isolating the salt thus formed.

5 The compounds of the present invention can be administered to a patient at dosage levels in the range of about 0.1 to about 2,000 mg per day. For a normal human adult having a body

- weight of about 70 kilograms, a dosage in the range of about 0.01 to about 10 mg per kilogram > of body weight per day is preferable. However, the specifi dqsage used can vary. For.example, the dosage can depended on a numbers of factors including the requirements of the patient, the 0 severity of the ^ρndition being treated, and the pharmacological activity of the compound being __^~ used. The determination of optimum dosages for a particular- patient is well-known to those ^■ skilled in the art. - - ' - . ^" _

Ideally, the active ingredient should be administered to achieve peak plasma concentrations of the active compound of from about 0.5 to about 75 μM, preferably, about 1 to

15 50 μM, most preferably, about 0.1 to about 5 μM. This may be achieved, for example, by the .

- ~ -intravenous injection of a 0.05 to 5% solution of the active ingredient, optionally in saline, or orally administered as a bolus containing about 10-500 mg of the active ingredient. Desirable - blood levels may be maintained by multiple oral dosing, or continuous infusion to provide about 0.01-5.0 mg/kg/hr or by intermittent infusions containing about 0.4-15 mg/kg of the active

20 ingredient(s).

The desired dose ^"may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day. The sub-dose itself may be further divided, e.g., into a number of discrete loosely spaced ^" „ administrations; such as multiple inhalations from an insufflator or by application of a-plurality_^

BIOLOGICAL ASSAYS The ability of a compound of the present invention to inhibit renin is -demonstrated using pharmacological models that are well known to the art, for example, using models such as the_. tests described below.- - .- - Determination of Renin IC₅₀ by tGFP FRET assay

The tGFP FRET (Green Fluorescent Protein Fluorescence Resonance Energy Transfer) assay utilizes a tandem GFP substrate (60kDa) containing nine amino acid recognition sequences for human renin flanked by two GFP proteins. The assay is used to determine the ability of a compound to act as an inhibitor of renin enzymatic activity by determination of that concentration of test-compound that inhibits by 50% (IC₅o) the ability of renin to cleave the tandem GFP substrate. The IC₅₀ value^are^'detemvined over an 11 -point curve at concentrations of 100 μMto IpM. Each compound concentration used to^'tonstruct the curve was dependent on renin inhibitor potency. For example, subnanomolar IC₅o values were determined over ail 11- pόint curve at concentrations of 10 μM to IpM. All other IC₅o values were determined over an 11-point curve at concentrations of 100 μM to .0065 μM. The concentrations were achieved by diluting a 9. InM stock of Human recombinant renin in the appropriate amount of buffer containing 50mM HEPES, ImM EDTA,^" 1% PEG (8000 MW), 1 mM DTT, 0.1% BSA, pH 7.4.to achieve the final concentration of 50.4 μlU. The_^tGFP substrate stock solution of 43μM was diluted with the appropriate amount of the above buffer to obtain the final concentration of 650 nM. In addition, 1 μl of the compound is diluted in DSMO to represent an eight-point log scale (5% final). The renin and compound are added to a^"384 capacity plate by ^"an automated robot (BIOMEK). The plate is incubated for 60 minutes; upon completion the tGFP substrate is added. ^" .. . . -

The IC₅₀ is determined by monitoring the increase in absorbance at 432/432 nm excitation, 530/475 nnr emission with a cutoff at 515/455 nm, in a fluorometric plate reader. The results of this evaluation are shown in Table 1.
