Description

  The present invention relates to a naphthalene derivative useful as a medicine. More specifically, the present invention relates to a naphthalene derivative effective as a renin inhibitor. Furthermore, the present invention relates to an antihypertensive agent comprising a naphthalene derivative effective as a renin inhibitor as an active ingredient.

  The renin-angiotensin (RA) system is an important hormone system for maintaining blood pressure and electrolyte balance in the body, and plays an important role in the onset and progression of cardiovascular diseases such as hypertension, congestive heart failure, and kidney damage. Yes.

  Renin, which is an important component of the RA system, is an aspartic protease that is secreted mainly into the blood from the kidney, and specifically decomposes angiotensinogen produced in the liver to produce angiotensin I. Angiotensin I is converted to angiotensin II by an angiotensin converting enzyme (ACE) present in lungs and vascular endothelial cells. Angiotensin II contracts blood vessels and stimulates the adrenal glands to stimulate aldosterone secretion. Aldosterone acts on the kidneys to retain sodium and excrete potassium. These cascades lead to an increase in blood pressure (Non-Patent Document 1).

  In recent years, RA-related components are also provided in peripheral tissues such as the heart, blood vessels, kidneys, adrenal glands, and fats, and central tissues, and (pro) renin receptors are activated as a new component. (Non-patent Document 2), the importance of the local (tissue) RA system is being recognized. In contrast to the circulatory RA system related to short-term circulatory regulation, the tissue RA system induces long-term remodeling of various organs such as the heart, kidney, and blood vessels, thereby causing organs such as cardiac hypertrophy, arteriosclerosis, and kidney damage. The possibility of causing a failure has been pointed out (Non-patent Document 3).

  Drugs that suppress the RA system include ACE inhibitors and angiotensin II receptor antagonists (ARBs), but these drugs (especially the former) are not only high blood pressure but also cardiovascular systems such as heart failure and diabetic nephropathy It has proven useful as a therapeutic agent for diseases and kidney diseases, and is widely applied clinically (Non-patent Documents 4 and 5).

  There are multiple steps to suppress the RA system. Among them, renin is located in the uppermost stream of the RA system and rate limiting this cascade, so inhibiting this is a theoretically very attractive approach. (Non-Patent Document 6, Non-Patent Document 7). In fact, aliskiren, a renin inhibitor developed in recent years, can remarkably suppress plasma renin activity in clinical trials targeting hypertensive patients and exhibit superior antihypertensive effects comparable to other RA inhibitors. It has been confirmed (Non-patent document 8, Non-patent document 9, Non-patent document 10).

Various renin inhibitors have been reported. For example, Patent Document 1 and Patent Document 2 report that derivatives having a piperidine ring are effective as renin inhibitors. In Patent Document 3, it is reported that a derivative having a pyrrolidine ring is effective as a renin inhibitor. The compounds disclosed in these documents are structurally characterized by a partial structure in which the 3-position of the piperidine ring and pyrrolidine ring is bonded to an amino group via a carbonyl group or a methylene chain. However, it has not been known so far that a group of compounds having 3- (naphthylcarbonylamino) piperidine as a basic skeleton is useful as a renin inhibitor.
