There is disclosed a compound of the following general formula (I):
its diastereomer, or a pharmaceutically acceptable acid
addition salt thereof;
wherein R1 is of the formula
or
in which;
n is an integer of from one to four;
Z is hydrogen, lower alkyl or hydroxy;
Y is hydrogen, lower alkyl, or OR where R is hydrogen, lower alkyl or lower alkanoyl;
A is a bond or a straight or branched alkylene of from one to four carbon atoms, with the proviso that A cannot be a bond when R1 is of Formula II and n is one;
X and X' are each, independently, hydrogen, lower alkyl, lower alkoxy, hydroxy, lower alkanoyl, nitro, trifluoromethyl, halogen, amino, monolower-alkyl or diloweralkylamino, or when taken X and X' together are a methylenedioxy group;
R2 is a) hydrogen, b) halogen, c) NR'R" where R' and R" are independently hydrogen, lower alkyl, phenyl, or phenyl substituted by lower alkyl, lower alkoxy, halogen, or trifluoromethyl, d) SR'" where R" is hydrogen, lower alkyl, lower alkanoyl, benzoyl, or phenyl;
R'2, R'3 and R'e are each, independently, hydrogen, alkanoyl having two to twelve carbon atoms, inclusive, in a straight or branched alkyl chain, benzoyl, or benzoyl substituted by lower alkyl, lower alkoxy, halogen, or R'2 and R'3 taken together are a five- membered ring having a total of up to twenty carbons; or R'e is, independently, a phosphate, hydrogen, or dihydrogen phosphate, or an alkali metal or ammonium, or dialkali or diammonium salt thereof; with the proviso that overall when R1 is II and X' X', Y, and Z are hydrogen, or lower alkyl then n cannot be two.
The novel N6-substituted adenosines have desirable ratio of affinities at A1 or A2 receptors and highly desirable central nervous system and cardiovascular activities, such as analgesic, antipsychotic, sedative, or antihypertensive as well as immunoinflammatory activity.
