Definitions
- the present invention has the following general formula useful for treating and preventing coronary artery disease, cerebral infarction, hypolipidemia, arteriosclerosis, etc., which has a therapeutic effect on high L p (a) blood and a lipid-lowering effect.
- the present invention relates to a novel benzofuran derivative represented by [I] and a pharmacologically acceptable salt thereof.
- R 1 represents chromium, halogen, or alkyl
- R 2 represents alkoxycarbonyl, aralkyloxycarbonyl, carboxy, hydr XIalkyl, or acyloxyalkyl.
- Z represents an acyl.
- L p (a) was initially detected in the blood of patients with sclerosis and was considered a risk factor for arteriosclerosis.
- Today it is known as a lipoprotein (Lipoprote in), which has the same apoprotein B-100 as the LDL molecule at the center and has an apoprotein ⁇ a) molecule attached thereto (modern medicine , No. 7 (1990)).
- L p (a) Since L p (a) is found only in mammals above human primates, it has a property that is incompatible with animal experiments using rodents and so on. Was late. Since L p (a) has the same basic structure as brassinogen, it is expected that L p (a) is present in blood to suppress the degradation of fibrin and to inhibit thrombolysis.
- L p (a) the distribution of L p (a) in the body, the distribution of L p (a) was found to be higher at the site where arteriosclerosis occurred, so it was speculated that L p (a) directly affected arteriosclerosis. In addition, L p (a) blood levels are not affected by conventional lipid-lowering agents, and arteriosclerosis may develop even in patients with low lipids. The relationship between (a) and the onset of arteriosclerosis was emphasized.
- ⁇ L p (a) emia has been found to be largely determined by transgenic traits.
- Nicotinic acid has been identified as a substance with a blood L p U) lowering effect (J. Internal Medici ne 226 271-276 (1989)), but side effects such as hot flush have been known. The above main effects were not satisfactory enough.
- L p U blood lipid lowering effect
- side effects such as hot flush have been known.
- the above main effects were not satisfactory enough.
- L p (a) lowering action substances that lower blood lipids are useful for the treatment of venous sclerosis according to the present invention. Therefore, it was presumed that a substance having a blood lipid lowering action in addition to the L p (a) lowering action would be more useful for treating the above-mentioned diseases.
- the gist of the present invention lies in the structure itself of the compound represented by the general formula [I].
- the compound according to the present invention is a novel compound not described in the literature.
- Examples of the halogen represented by R 1 in the general formula [I] include fluorine, chlorine, bromine and iodine.
- the alkyl is preferably a straight-chain or branched-chain alkyl having 1 to 7 carbon atoms, for example, methyl, ethyl, n-butyl, isopropyl, n-butyl, isobutyl, tert-butyl, n-butyl -Pentyl, isopentyl, n-hexyl, isohexyl, n-hexyl, isoheptyl and the like.
- the alkyl moiety of the completion alkoxycarbonyl represented by R a may be mentioned exemplified alkyl such as in the R 1.
- the aralkyloxycarbonyl represented by R 2 is preferably one having 8 to 14 carbon atoms, for example, penziloxycarbonyl, 2-methylzindioxycarbonyl, 3-methylzindioxycarbonyl, 4-methylpentyloxycarbonyl, phenethyloxycarbonyl, 3-phenylpropoxycarbonyl, 1-naphthylmethoxycarbonyl, 2-naphthylmethoxycarbonyl, 2- (1-naphthyl) ethoxycarbo Nil, 3- (l-naphthyl) propoxycarbonyl and the like.
- hydroxyalkyl a straight-chain or branched alkyl having 1 to 7 carbon atoms, which is substituted with hydroxy, is preferred.
