Definitions
- the present invention relates to novel indoline compounds and their pharmaceutical uses. More specifically, the present invention relates to a novel indoline compound having a cholesterol acyltransferase (hereinafter referred to as “ACAT”) inhibitory action and an inhibitory action on lipid peroxidation, or a pharmaceutically acceptable salt thereof, in the form of an acyl-enzyme A. .
- ACAT cholesterol acyltransferase
- arteriosclerosis is extremely important as a cause of various cardiovascular diseases, and active research is being conducted with the aim of suppressing the progression of atherosclerosis or regressing atherosclerosis.
- Cholesterol in food is esterified in the small intestinal mucosa and then absorbed as chiromiclone and translocates into the blood. It is known that ACAT plays an important role in the production of cholesterol ester in the small intestinal mucosa. In addition, cholesterol synthesized in the liver is esterified by ACAT and secreted into the blood as very low density lipoprotein (VLDL). Therefore, it is thought that by inhibiting ACAT in the small intestinal mucosa and liver and suppressing esterification of cholesterol, the amount of cholesterol in the blood can be reduced. Drugs that inhibit cholesterol deposition more directly in the arterial wall are expected to be more effective in preventing or treating arteriosclerosis, and are being actively studied, but the ideal drug is still being realized. Not. In the arterial wall, cholesterol is esterified by ACAT of macrophages and smooth muscle cells and accumulated as cholesterol ester.Therefore, inhibition of ACAT in the arterial wall is expected to effectively suppress cholesterol ester accumulation. Is done.
- ACAT inhibitors inhibit cholesterol absorption in the small intestine, secretion of cholesterol from the liver, and the accumulation of cholesterol in the arterial wall. It is considered to be an effective drug.
- ACAT inhibitors include, for example, amide and urea derivatives (J. Med. Chem., 29: 1131 (1986), JP-A-2-117651, JP-A-2-7259, JP-A-41 234839, JP-A-4-327564, JP-A-5-32666, etc.) have been reported.
- the creation and pharmacological research of these compounds is still not enough.
- these compounds have a sufficient effect of lowering blood cholesterol and inhibiting cholesterol accumulation in the arterial wall by inhibiting ACAT in suppressing clinical progression and regression of arteriosclerosis.
- many of the conventional ACAT inhibitors have extremely high fat solubility, and thus often have low oral absorption. If the oral absorption is good, there is a concern that organ damage such as the adrenal gland and the liver may occur.
- highly lipid-soluble, low-absorbing ACAT inhibitors may cause diarrhea in the clinic.
- LDL low-density lipoprotein
- lipid peroxidation in the living body is known to be closely related to the development of arteriosclerosis and ischemic diseases in the brain and cardiovascular system. Therefore, a compound that has both an ACAT inhibitory action and a lipid peroxidation inhibitory action can effectively and reliably reduce the accumulation of cholesterol ester in the arterial wall, and also inhibit the lipid peroxidation in vivo. Can prevent and treat various vascular lesions caused by these, and have high utility as pharmaceuticals
- An object of the present invention is to provide a compound having an ACAT inhibitory action and a lipid peroxidation inhibitory action, and a pharmaceutical use thereof (in particular, an ACAT inhibitor and a lipid peroxidation inhibitor).
- the novel indolin compound of the present invention not only has a strong ACAT inhibitory action, but also has a lipid peroxidation inhibitory action, and has excellent oral absorption.
- the present inventors have found that they have a strong antihyperlipidemic action and an anti-atherosclerotic action and have completed the present invention.

They were fed only during the interval (9: 0 to 18:00) and were reared for one week.
- Triton WR-13339 method Mouse liver lipid secretion inhibitory effect
- Triton WR—1 3 3 hours after administration blood was collected again from the orbital venous plexus. Plasma is separated from the collected blood, plasma TC is measured using a commercial measurement kit (Wako Pure Chemical Industries, Ltd.), and the change in blood concentration three hours after administration of Triton WR-133 is calculated, and cholesterol from the liver is calculated. The secretion rate was determined. The secretion rates of the control group and the test compound group were compared, and the secretion inhibition rate by the test compound was calculated. Table 3 shows the results.
- LD L suspension (0. 5m g protein / m L ) was DMS O or a 0. 5 mL was added dissolved test compound solution 5 // L (final concentration 1 0- 5 M) in DMSO, immediately An aqueous solution of copper sulfate (5 ⁇ L, final concentration: 5 / ⁇ ⁇ ) was added, and the mixture was incubated at 37 ° C for 1 hour. After the incubation, 5 ⁇ L of EDTA'2Na solution (final concentration: ImM) was added, and the lipid peroxide concentration in the sample was measured immediately by the Yagi method.
- the lipid peroxide in the sample is colored by the thioparbituric acid method and is measured as malonaldehyde, and the activity of the test compound is inhibited by malonaldehyde formation (%) [How much malonaldehyde is compared to the control Production inhibited force].
- Table 4 shows the results. Table 4
- the compound (I) of the present invention and a pharmaceutically acceptable salt thereof are excellent in A against mammals (humans, rabbits, rabbits, dogs, cats, rabbits, rats, mice, hamsters, etc.). Shows CAT inhibitory action and lipid peroxidation inhibitory action, And is useful as a lipid peroxidation inhibitor. That is, it is useful for prevention and treatment of arteriosclerosis, hyperlipidemia, arteriosclerotic lesions in diabetes, and ischemic diseases such as brain and heart.
- the present invention is based on Japanese Patent Application No. 2002-208878 filed in Japan, the contents of which are incorporated in full herein.
