preparation example Construction

[0343] The production method of the compound of the present invention is explained below.

[0344]The compound represented by the general formula (I) or a salt thereof can be synthesized by various known synthesis methods by utilizing the characteristics based on its basic skeleton or type of substituent. Typical production methods are illustrated below, but are not limited to the methods described below. It should be noted that, depending on the type of functional group, sometimes at the stage of raw materials or intermediates, the functional group is first changed into an appropriate protecting group, that is, a group that is easily converted into the functional group is effective in preparation technology, and can be removed as needed. protecting group to give the desired compound. Examples of these functional groups include hydroxyl groups, carboxyl groups, and amino groups, and examples of these protective groups include those described in "Protective Groups in Organic S...

Abstract

Disclosed is a homocysteine synthase inhibitor which is useful for the prevention or treatment of a disease associated with homocysteine synthase. Specifically disclosed is a compound represented by general formula (I) [wherein each symbol is as defined in the description], a pharmacologically acceptable salt of the compound, or a solvate of the compound or the pharmacologically acceptable salt, which can be used as the homocysteine synthase inhibitor.

Description

technical field [0001] The present invention relates to novel amide derivatives. More specifically, it relates to a homocysteine ​​synthase inhibitor comprising an amide derivative, a pharmacologically acceptable salt thereof, or a solvate thereof as an active ingredient. Background technique [0002] Homocysteine ​​is a sulfur-containing amino acid and an important intermediate in the metabolism of the essential amino acid methionine. Homocysteine ​​is maintained at an extremely low concentration in cells, and excess homocysteine ​​is released outside the cells, that is, into the blood. Dr. McCully reported 30 years ago that this homocysteine ​​is the cause of vascular diseases such as arteriosclerosis and myocardial infarction (Non-Patent Document 1). Afterwards, according to clinical tests, it was proved that patients with arteriosclerosis in peripheral blood vessels and cerebral blood vessels had high homocysteine ​​levels. (Non-Patent Document 2). Furthermore, in mo...
