Description
This invention relates to novel pyrroloquinoline compounds and pharmaceutically acceptable salts thereof. More particularly, it relates to novel pyrroloquinoline compounds and pharmaceutically acceptable salts thereof, which have inhibitory activity against the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase), to a process for preparation thereof, to a pharmaceutical composition containing the same, to a use of the same as a medicament, and to a method for treating hypercholesterolaemic and hyperlipoproteinaemic states and associated conditions. Accordingly, one object of the present invention is to provide pyrroloquinoline compounds and pharmaceutically acceptable salts thereof, which function as antihypercholesterolemic or antihyperproteinamic agents by limiting biosynthesis via inhibiting the activity of HMG-CoA reductase and therefore are capable of lowering blood serum cholesterol levels and blood lipid levels. Another object of the present invention is to provide a process for preparation of pyrroloquinoline compounds and pharmaceutically acceptable salts thereof. Another object of the present invention is to provide a pharmaceutical composition comprising, as an active ingredient, said pyrroloquinoline compounds and pharmaceutically acceptable salts thereof. Still further object of the present invention is to provide a use of said pyrroloquinoline compounds and pharmaceutically acceptable salts thereof as a medicament and a method for treating hypercholesterolemic states, hyperlipoproteinemic states and associated conditions in human being or animal. High levels of blood cholesterol and blood lipids are conditions which are involved in the onset of arteriosclerosis. It is well known that inhibitors of HMG-CoA reductase are effective in lowering the level of blood plasma cholesterol, especially low density lipoprotein cholesterol (LDL-C). It has now been established that lowering LDL-C levels affords protection from coronary heart disease, cerebral infarction, and the like. The pyrroloquinoline compounds of this invention inhibit HMG-CoA reductase and so inhibit cholesterol biosynthesis. They lower concentrations of chlolesterol in blood. Thus they are useful for treating hypercholesterolemic and hyperlipoproteinemic states (e.g. atherosclerosis), associated conditions (e.g. angina, myocardial infarction, cerebral vascular occlusion, arterial aneurism, peripheral vascular disease, recurrent pancreatitis and xanthomas), diabetic nephropathy, and the like. The object pyrroloquinoline compounds of this invention are novel and can be represented by the following general formula: ##STR3## in which R.sup.1 and R.sup.2 are each hydrogen or lower alkyl, R.sup.3 is aryl or heterocyclic group, each of which may be substituted by suitable substituent(s), R.sup.4 is hydrogen, halogen or lower alkyl, A is methylene, methine, oxa, thia, sulfinyl or sulfonyl, Y is vinylene or ethylene, Z is a group of the formula: ##STR4## wherein R.sup.5 is carboxy or protected carboxy, and R.sup.6 is hydrogen or hydroxy-protective group, and the line of is a single or double bond, or pharmaceutically acceptable salts thereof.

A solution of 5,6-dihydro-4,4-dimethyl-1-(4-fluorophenyl)-4H-pyrrolo[3,2,1-ij]quinoline (3.70 g) in dry acetonitrile (9 ml) was slowly added to the reaction mixture at the same temperature. The reaction mixture was refluxed for 7 l hours under nitrogen, cooled to room temperature and slowly poured into a cold solution of sodium hydroxide (6.34 g) in water (130 ml) with stirring. The reaction mixture was extracted twice with toluene. The extracts were combined, washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was chromatographed on a silica gel column eluting with a mixture of n-hexane and ethyl acetate (5:1, V/V). The fractions containing the object compound were collected and evaporated under reduced pressure. The residual oil was triturated with n-hexane to give yellow crystals of (E)-3-[5,6-dihydro-4,4-dimethyl-1-(4-fluorophenyl)-4H-pyrrolo[3,2,1-ij]quinolin-2-yl]acrylaldehyde (3.11 g). mp: 157.5.degree.-160.5.degree.

The suspension was cooled to -20.degree. C. under nitrogen. A tetrahydrofuran (8 ml) was dropwise added with stirring at -20.degree. to -15.degree. C. under nitrogen to the suspension. The reaction mixture was stirred at -20.degree. to -15.degree. C. for 30 minutes and 1.6 M n-butyllithium/hexane (8.6 ml) was dropwise added thereto with stirring at -20.degree. to -15.degree. C. for 30 minutes. A solution of (E)-3-[5,6-dihydro-4,4-dimethyl-1-(4-fluorophenyl)-4H-pyrrolo[3,2,1-ij]quinolin-2-yl]acrylaldehyde (3.07 g) in dry tetrahydrofuran was dropwise added to the mixture over a 30-minute period at -20.degree. to -15.degree. C. under nitrogen. The reaction mixture was stirred at -20.degree. to -15.degree. C. for 1 hour and quenched at -0.degree. to 0.degree. C. with saturated aqueous ammonium chloride. The tetrahydrofuran was evaporated under reduced pressure and the residue was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, filtered and evaporated under reduced pressure. The residue was chromatographed on "florisil" (trademark, made by floridin Company) (120 g) eluting with a mixture of n-hexane and ethyl acetate (5:2, V/V). The fractions containing the object compound were combined and concentrated under reduced pressure to give yellow syrup of methyl (E)-7-[5,6-dihydro-4,4-dimethyl-1-(4-fluorophenyl)-4H-pyrrolo[3,2,1-ij]quinolin-2-yl]-5-hydroxy-3-oxohept-6-enoate (2.60 g).

EXAMPLE 1-1 ##STR158## A mixture of 1M triethylborane/n-hexane (12.0 ml) and pivalic acid (0.06 g) was stirred at room temperature for 2 hours under nitrogen. A solution of methyl (E)-7-[5,6-dihydro-4,4-dimethyl-1-(4-fluorophenyl)-4H-pyrrolo[3,2,1-ij]quinolin 2-yl]-5-hydroxy-3-oxohept-6-enoate (2.57 g) in dry tetrahydrofuran (25 ml) was added to the mixture. After 2 hours, the reaction mixture was cooled to -78.degree. C. and methanol (12 ml) was added dropwise thereto. Sodium borohydride (0.54 g) was carefully added by portions at -75 to -70.degree. C. under nitrogen to the reaction mixture. After being stirred at the same temperature for 1 hour, the reaction mixture was quenched at -10.degree. C. to 0.degree. C. with 0.5 M aqueous citric acid, warmed to room temperature and extracted with diethyl ether. The extract was washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was dissolved in methanol (30 ml) warmed to 40 to 45.degree. C. and evaporated under reduced pressure. After this procedure was repeated two more times, the residue was chromatographed on a silica gel column eluting with a mixture of n-hexane and ethyl acetate (2:1, V/V). The fractions containing the object compound were collected and concentrated under reduced pressure to give white crystals of methyl (.+-.)-erythro-(E)-7-[5,6-dihydro-4,4-dimethyl-1-(4-fluorophenyl)-4H-pyrrolo[3,2,1-ij]quinolin-2-yl]-3,5-dihydroxyhept-6-enoate (1.84 g). mp: 108.5.degree.-109.5.degree.
