Definitions
- the present invention relates to dihydropyridine derivatives.
- the present invention provides compounds of formula I, wherein
- alkyl of 1 to 6 carbon atoms is preferably of 1 to 4 carbon atoms, especially of 1 to 2 carbon atoms.
- Any alkyl, alkoxy, alkylthio or or alkylsulfonyl radical of 1 to 4 carbon atoms is preferably of 1 or 2 carbon atoms.
- the alkyl moiety of cycloalkylalkyl or cycloalkyalkoxy is conveniently methyl.
- Halogen means fluorine, chlorine or bromine and is especially chlorine.
- Cycloalkyl or the cycloalkyl moiety of cycloalkylalkyl or cycloalkylalkoxy is conveniently cyclopropyl or cyclopentyl or cyclohexyl.
- alkenyl, alkynyl, alkenyloxy, alkynyloxy or phenylalkenyl is preferably not in the ⁇ , ⁇ position.
- Alkenyl, alkenyloxy, alkynyl or alkynyloxy preferably has 3 to 5 carbon atoms.
- Alkenyl or the alkenyl moiety of alkenyloxy is conveniently allyl or 2-methylallyl.
- Alkynyl or the alkynyl moiety of alkynyloxy is conveniently propynyl.
- Phenylalkenyl preferably has the trans-configuration and is for example cinnamyl.
- R is optionally substituted phenylalkyl
- the phenyl group is preferably unsubstituted.
- the phenyl group is di- or tri-substituted, preferably the substituents are the same.
- R 3 and/or R 4 is alkoxy, this is preferably ethoxy or methoxy.
- R 3 and/or R 4 is alkoxyalkoxy or hydroxyalkoxyalkoxy, preferably the carbon chain between the two ether oxygen atoms is of 2 carbon atoms.
- the hydroxy group of hydroxyalkoxy or of hydroxyalkoxyalkoxy is preferably not attached to the carbon atom attached to an ether oxygen atom.
- R is preferably hydrogen.
- R 2 is conveniently identical to R 5 .
- R 2 and/or R 5 is preferably methyl.
- R 3 and/or R 4 is preferably alkoxy or alkoxyalkoxy, especially n-butyloxyethoxy.
- R . is conveniently halogen, alkyl or alkoxy, or especially hydrogen.
- R 6 is conveniently adjacent to the dihydropyridine moiety which in turn is conveniently in the 4-position.
- the process may be effected in conventional manner for analogous dihydropyridine syntheses, e.g. according to Hantzsch.
- R 2 is identical to R 5 and R 3 is identical to R 4
- At least 2 moles of a compound of formula IV per mole of a compound of formula II are present.
- a compound of formula II may be reacted with a compound of formula VI, wherein R 1 , R 4 and R 5 are as defined above.
- At least 2 moles of a compound of formula VI per mole of a compound of formula II are present.
- R is hydrogen.
- a compound of formula VI may be formed as an intermediate during the reaction of a compound of formula IV and a compound of formula V.
- R 2 , R 3 , R 4 and R 5 are not identical that more than one isomer of formula I may be formed. If so these may be separated in conventional manner, e.g. by thin layer chromatography.
- the reaction is a ring cyclisation.
- Z and Z' are both oxygen, then an amine of formula V should be present.
- reaction may be effected conveniently in solution.
- a suitable solvent is water, ethanol, dioxane, dimethyl formamide, dimethyl sulphoxide, pyridine or glacial acetic acid.
- Suitable reaction temperatures may be from 20 to 160°C, preferably from 60 to 120°C.
- the compounds of formula I exhibit pharmacological activity. In particular, they lead to a dilation of the coronary vessels as demonstrated by the results of tests measuring the blood flow to the myocardium of an anaesthetised cat by means of the microsphere method upon the administration of the active substance i.v. or i.d.
- the compounds of formula I also possess a favourable effect against angina pectoris, as shown by the increase of the coronary flow of an anaesthetised cat upon administration of the active substance.
- the compounds of formula 1 are therefore indicated for use in the treatment of coronary insufficiency.
- an indicated daily dose is from about 5 to 100 mg, conveniently administered in divided doses 2 to 4 times a day in unit dosage form containing from about 1.25 to about 50 mg, or in sustained release form.
- the compounds of formula I exhibit antihypertensive activity, as indicated in standard tests, e.g. in the Grollman rat test [see A. Grollman, Proc. Soc. Expt. Biol. and Med. 57, 104 (1944)J on s.c. administration of from 0.1 to 10 mg/kg animal body weight of the compounds.
- an indicated daily dose is from about 5 to about 1000 mg, conveniently given in divided doses 2 to 4 times a day in unit dosage form containing about 1.25 mg to about 500 mg, or in sustained release form.
- the compounds of formula I may be administered in the form of a pharmaceutical composition.
- the present invention accordingly provides a pharmaceutical composition comprising a compound of formula I in association with a pharmaceutical carrier or diluent.
- Such compositions may be prepared by conventional techniques to be in conventional forms, for example capsules or tablets.
- the compounds of Examples 1 and 2 are the preferred compounds.
- the coronary insufficiency utility is preferred utility.
- R is hydrogen, alkyl, alkenyl, cycloalkyl of 3 to 6 carbon atoms or phenylalkyl; the phenyl ring being unsubstituted or substituted by one, two or three substituents chosen from one or two halogen radicals, one or two alkyl groups of 1 to 4 carbon atoms, one to three alkoxy groups of 1 to 4 carbon atoms; R 3 and R 4 , indpendently, are alkyl, alkenyl, cycloalkyl of 3 to 6 carbon atoms, alkoxy, hydroxyalkoxy of 2 to 6 carbon atoms, alkoxyalkoxy of 3 to 6 carbon atoms, hydroxyalkoxyalkoxy of 4 to 8 carbon atoms, alkenyloxy, or cycloalkyloxy of 3 to 6 carbon atoms, and R 6 is other than alkylsulfonyl.
