Adenosine-5'-carboxylic acid derivatives of the general formula: ##STR1## wherein Z is two hydrogen atoms or a divalent lower alkylidene radical, ##STR2## R is an aliphatic or arylaliphatic radical, and R.sub.1 and R.sub.2 are independently a hydrogen, hydroxyl, amino, lower alkyl, lower alkenyl, optionally N-alkylated lower aminoalkyl, cycloalkyl, hydroxyalkyl or piperidinyl radical, orR.sub.1 and R.sub.2 taken together are a divalent ethylene radical containing 4-7 carbon atoms optionally interrupted by an oxygen or sulfur atom or by an imino, alkylimino or arylimino radical or a pharmacologically compatible salt thereof.The esters surprisingly can be prepared by esterifying the acid in the presence of sulfuric acid without hydrolyzing the sugar group. While the esters have some activity, they can be used to make the amides which are characterized by marked coronary activity.

摘要:
The present invention provides pharmaceutical compositions containing N-substituted aziridine-2-carboxylic acid derivatives of the general formula: ##STR1## wherein X is a carboxyl, a cyano, an alkoxycarbonyl or an optionally substituted carbamoyl radical, R is a hydrogen atom, an aliphatic hydrocarbon radical which is saturated or can contain one or more unsaturations and can be substituted one or more times by halogen, alkoxy, hydroxyl, dialkylamino, dialkylaminoxy, cycloalkylamino, acylamino, acyl, nitro, alkylthio, alkylsulphinyl, alkylsulphonyl, cyano, carboxyl, alkoxycarbonyl or carbamoyl or by cycloalkyl or cycloalkenyl radicals optionally carrying alkyl, alkoxy or alkoxycarbonyl radicals, optionally interrupted by hetero atoms and optionally bridged, or by an aryl, hetaryl, aryloxy, arylthio, acyloxy, alkoxycarbonylamino or isothioureido radical, or R is a cycloalkyl or cycloalkenyl radical optionally substituted by alkyl, alkoxy or oxo groups, optionally interrupted by hetero atoms and optionally bridged, or is an aryl or hetaryl radical which can be substituted one or more times by halogen, alkoxy, alkyl, hydroxyl, alkoxycarbonyl, carbamoyl, dialkylamino, cycloalkylamino, acylamino, nitro, cyano, acyl, alkylthio, alkylsulphinyl, alkylsulphonyl, sulphamoyl, phenyl, trifluoromethyl, aryloxy, acyloxy or methylenedioxy radicals and R.sub.1 is a hydrogen atom or an alkyl or phenyl radical; and the pharmacologically acceptable salts thereof, in admixture with a pharmaceutical diluent or carrier. The present invention also provides, as new compounds, N-substituted aziridine-2-carboxylic acid derivatives of general formula (I') but with the proviso that when X is a carbamoyl or alkoxycarbonyl radical and R.sub.1 is a hydrogen atom, R is not a methyl, ethyl, isopropyl or benzyl radical; and the pharmacologically acceptable salts thereof, and also provides processes for the preparation of these new compounds. Furthermore, the present invention is concerned with the use of the compounds of general formula (I') and of the pharmacologically acceptable salts thereof for combating diseases associated with a weakening of the immune system.
