Definitions
- the present invention relates to the chemical branch, the pharmaceutical branch and specifically with regard to obtaining new molecular entities, synthetic variants of diazepines fused to dihydropyridines of the general formula:
- R represents H, alkyl group (preferably alkyl groups of up to 8 straight chain carbon atoms or branched, such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl and octyl, and the chain isomers of all of the above; as well as cyclic alkyls, and substituted alkyls, preferably substituted with halogens; vinyl and vinylsubstituted; and cyclic alkyl chains , preferably the cyclohexyl group.
- R also represents an aryl group (benzyl, naphthyl and substituted naphthyl or anthracil).
- R also represents heteroaryl, substituted heteroaryl, where heteroaryl and substituted heteroaryl preferably refers to furfuryl, furfuryl substituted, pyrrolidyl, substituted pyrrolidyls, thiophenyl, substituted thiophenyl, pyridyl (2-pyridyl, 3-pyridyl and 4-pyridyl), substituted pyridyl, quinolinyl (2-quinolinyl, 3- quinolinyl, 4-quinolinyl), pyrazolyl.
- R represents H, alkyl group, straight or branched chain and alicyclic, preferably with a number of carbon atoms between 1 and 16.
- R ⁇ also represents OR ' where R ' independently represents H, or its salts of Sodium (Na) and Potassium (K); alkyl groups of 1 and up to 24 carbon atoms, straight or branched chains such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl.
- R ' also represents lipid chains derived from mono and polyunsaturated fatty acids of up to 24 carbon atoms.
- R It also represents amino acid residues of the type -NH-CH (R4) -COOH, where R 4 are amino acid residues, preferably valine, phenylalanine, alanine, histidine, Usine, tryptophan, cysteine, leucine, tyrosine, isoleucine, proline and methionine; Rl also represents small peptide chains of between 2 and up to 12 amino acids, obtained by combinations of some of them chosen independently.
- Ri also represents -NHR , where R 5 is a thiazole and substituted thiazole ring, 4-phenylthiazole or 4- substituted phenylthiazole; R 5 also represents a phenyl and substituted phenyl substituent.
- R 2 represents an alkyl or cycloalkyl group; alkyl groups can be straight or branched chain between 1 and up to 16 carbon atoms; groups - (CH 2 ) n-NH2 and groups - (CH 2 ) n-OH, where n is 1 and up to 8.
- cycle A is a 6-membered aromatic ring fused to the diazepine ring and represents a ring of benzene or substituted benzene, forming a benzodiazepine, fused in such a way that it implies a structure and all its positional isomers and all possible tautomers.
- the benzene fused to diazepine represented as ring A, is in turn substituted by one and up to four substituents independently selected from OH, COOH, CH 3 , N0 2 , NH 2 , CHO (formyl group), halogens and combinations thereof .
- cycle A is also a 6-membered heterocyclic ring fused to the diazepine ring and represents a ring of pyridine and substituted pyridine, preferably with halogens.
- the pyridine ring may be fused to the diazepine ring in such a way that it implies a structure and all its possible position isomers and all possible tautomers.
- This new type of compounds can serve as a basis for medications with therapeutic applications in the treatment of anxiety, ischemia, epilepsy, high blood pressure and other cardiovascular, cerebrovascular disorders. neurodegenerative, neuropsychiatric, neurological and others related to the cardiovascular system.
- Compounds of type I, II, III, X, XI and XII are obtained by fusion of a properly substituted 1,4-dihydropyridine derivative, with a disubstituted ortho-diamino compound, ortho-phenylenediamine, ortho-diaminopyridines, r-diaminopyrimidines , to generate tricyclic (I, II, III) and tetracyclic (X, XI and XII) compounds derived from fused diazepines or diazepinones to the 1,4-dihydropyridine derivative.
- the new derivatives are obtained as a racemic modification, when starting from the racemic 1,4-dihydropyridine derivatives, obtained in turn through their synthetic precursors, which are also obtained in the form racemic
- the enantiomers can be resolved and obtained separately, with an enantiomeric excess greater than 90%, and is carried out by enantiomeric resolution of any of the starting intermediates, or by enantiomeric resolution directly in the final product, preferably by enzymatic resolution, with a previous chemical transformation (which is not always necessary) to facilitate the resolution process, and its subsequent transformation to the original structure already resolved. All separate enantiomers were further characterized by measuring their specific rotation.
- Benzodiazepines constituted the first pharmacological entity called privileged structures.
- benzodiazepines act as depressants of the central nervous system (CNS) by inhibitory action of GABA When part of a connected inhibiting bidirectional system between different areas of the CNS.
- CNS central nervous system
- GABA central nervous system
- the novelty of the present invention consists mainly in obtaining a tricyclic or tetracyclic molecular system consisting of a diazepine derivative fused to a DHP ring, with possible application in the treatment of cardiovascular, cerebrovascular, neurodegenerative, neuropsychiatric and neurological diseases, as well as the possibility of obtaining them by a simple synthetic process, using as starting material derivatives of 1,4-dihydropyridines.
- EP 1593683 and EP1 157992 describe the production of molecules derived from dihydro-2,3-benzodiazepine as potential anticonvulsants, but employs hydrogen type substituents, alkyl chains and aromatic rings such as phenyl, thienyl, furyl, pyridyl, imidazolyl, benzimidazolyl, benzothiazolyl and pthalazinyl.
- EP-349949 describes benzodiazepine derivatives substituted with heterocyclic groups substituted in turn with aryl, hydroxyl, carboxylic groups.

- US20020103371 describes benzodiazepine derivatives modulating the GABA receptor, but they do not relate dihydropyridines.
- EP-733634 describes the obtaining of new molecular entities derived from thieno (2,3-B) (1, 5) benzodiazepine.
- EXAMPLE 1 SYNTHESIS OF THE SYNTHETIC INTERMEDIARY 4-ARIL-5-CARBONILACOHOXI- 6-METHYL-2-OXO-l, 2,3,4-TETRAHYDROPIRIDINE USEFUL FOR THE PREPARATION OF TYPE I, II, III COMPOUNDS. METHOD 1.
- EXAMPLE 2 SYNTHESIS OF THE SYNTHETIC INTERMEDIARY DERIVED FROM 4-ARIL-5- CARBONILACOHOXI-6-METHYL-2-OXO-l, 2,3,4-TETRAHYDROPIRIDINE, USEFUL FOR THE PREPARATION OF COMPOUNDS OF TYPE I, II, III, IV , V, VI, VII, XIII, IX, X, XI and XII.
- the 4-aryl-3-carbonyl-alkoxy-2-methyl-6-chloro-5-formyl-1, 4-dihydropyridine derivatives constitute another synthesis intermediate.
- an equimolar amount of phosphorus oxychloride is added at room temperature.
- a solution of the corresponding 4-aryl-5-carbonylakoxy-6-methyl-2-oxo-2,3,4-tetrahydropyridine derivative is added.
- an aqueous solution of sodium acetate is added and stirred for a time 10-30 minutes.
- the organic phase is separated and the solvent is removed in vacuo.
- the solid obtained is recrystallized from ethanol.
- the corresponding derivative of 1,4-dihydropyridine derivative is dissolved in ethanol in a balloon equipped with magnetic stirring.
- the corresponding 1,2-diamine is added to the resulting solution.
- the reaction mixture is stirred at temperatures between 10-78 ° C for a few hours, observing the appearance of a precipitate. It is filtered, and purified by washing with ethanol. For some of the compounds it is necessary to isolate the final products by means of the column chromatography technique.
- EXAMPLE 7 EFFECT OF DIFFERENT SYNTHETIC VARIANTS OF DIAZEPINES FUSED TO DIHYDROPIRIDINS ON EXPLORATORY BEHAVIOR IN MOUSES.
- the open field trial has been a widely used test in the evaluation of drugs with a sedative effect, in which the number of animal stops and / or crossings through the central area of an open field is quantified; These behaviors are indicative of rodent exploratory behavior. Sedative drugs decrease their exploratory activity.
