Description

BACKGROUND OF THE INVENTION

The present invention relates to novel 1-acyl-2,3-dihydro-4(1H)-quinolinone-4-oxime derivatives, processes for producing said derivatives, intermediate compounds, novel 1-acyl-2,3-dihydro-4(1H)-quinolinone derivatives, to produce said derivatives, processes to produce said intermediate compounds, and compositions containing said derivatives with potent diuretic activity that can be used for treating and/or preventing hypertension, oedema and/or for removing ascites.

For the treatment of hypertension, benzothiazide derivatives or so-called loop diuretics have been widely used to lower blood pressure. These agents act mainly on the distal part of renal tubule or the loop of Henle and increase renal excretion of electrolytes and water. Many of these diuretics, however, are known to show several adverse reactions in common, for example, hypokalemia, hyperuricemia, decrease in sugar tolerance and disorder in lipid metabolism.

Diuretic agents have also been used for the treatment of oedema resulting from retention of water and electrolytes based on cardiac or renal insufficiency or on metabolic disorders, but such conventionally used diuretics show only marginal efficacy against retention of ascites which is often observed in the patients with abdominal tumor or liver cirrhosis.

These benzothiazide diuretics and loop diuretics are known to share common chemical substructures.

From the foregoing background, it has been desired to develop novel diuretics that are useful in the treatment of hypertension, oedema and removal of ascites and that do not cause the aforementioned adverse reactions by synthesizing compounds whose chemical structures are novel and different from those of known diuretics.

SUMMARY OF THE INVENTION

An object of the present invention is to provide novel 1-acyl-2,3-dihydro-4(1H)-quinolinone-4-oxime derivatives and salts thereof, solvates of said derivatives and solvates of said salts.

Another object of the present invention is to provide processes for producing novel 1-acyl-2,3-dihydro-4(1H)-quinolinone-4-oxime derivatives.

A further object of the present invention is to provide compositions for treating hypertension, oedema and ascites which comprise novel 1-acyl-2,3-dihydro-4(1H)-quinolinone-4-oxime derivatives as active components.

A further object of the present invention is to provide intermediate compounds, novel 1-acyl-2,3-dihydro-4(1H)-quinolinone derivatives, in the synthesis of 1-acyl-2,3-dihydro-4(1H)-quinolinone-4-oxime derivatives and processes for producing such intermediate compounds.

The present invention is based on the selection of 1-acyl-2,3-dihydro-4(1H)-quinolinone-4-oxime derivatives, namely 0-sulfate, 0-mesylate, 0-methylphosphate and 0-carboxymethyl ether, especially 0-sulfate of 4-oxime.

The compounds of the present invention containing these substituents have potent hypotensive, anti-oedematous and diuretic effect as well as an activity to remove ascites and are extremely useful for the treatment of diseases and disorders mentioned above.

Now, typical but non-limiting examples of formulations of the compound of this invention will be shown below.

Formulation A (Capsules)

Compound 6, 40 g of weight, 645 g of lactose and 15 g of magnesium stearate were weighed and mixed until the mixture became homogeneous. The mixture was then filled in No. 1 hard gelatin capsule at 350 mg each to obtain capsule preparation.

Formulation B (Tablets)

Compound 6, 50 g of weight, 800 g of lactose, 120 g of poteto starch, 15 g of polyvinyl alcohol and 15 g of magnesium stearate were weighed. The weighed amount of compound 6, lactose and potato starch were mixed until accomplishing homogeneity. Then aqueous solution of polyvinylalcohol was added to the mixture and granulated by wet process. The granules were then dried, mixed with magnesium stearate and pressed into tablets, each weighing 200 mg.

Formulation C (Powder)

Compound 11, 100 g of weight, 890 g of lactose and 10 g of magnesium stearate were weighed and mixed until 10 g of magnesium stearate were weighed and mixed until the mixture became homogeneous to obtain 10% powder preparation.

Formulation D (Rectal suppository)

Compound 4, 100 g of weight, 180 g of polyethyleneglycol 1500, 720 g of polyethyleneglycol 4000 were ground well in a mortar and formulated into suppository by melting and casting in appropriate mold.

Formulation E (Injection)

Compound 11, 1 g of weight, was weighed and dissolved in 200 ml of distilled water for injection. The solution was filtered, sterilized. Two milliliters each of the sterilized solution was poured into 5-ml ampoules and sealed to obtain preparation for injection.
