- N6 -substituted adenosines
-
The present inventions are novel N6 -substituted adenosines wherein the N substituent is STR1 wherein Ar is an unsubstituted or substituted (1) phenyl, (2) 1- or 2-naphthalenyl, (3) 2- or 3-thienyl, (4) 2- or 3-furanyl, (5) 2-, 4-, or 5-thiazyl, (6) 2-, 3-, or 4-pyridyl, or (7) 2-pyrimidyl wherein the substituents include at least one of lower alkyl, halo, trifluoromethyl, hydroxy, lower alkoxy, lower acyloxyamino, N-lower monoalkyl or N,N-lower dialkylamino, lower thioalkyl, lower alkylsulfonyl, or nitro and R' is hydrogen or alkyl, A is STR2 wherein q, q', or q" are one to four, n and m are independently zero to three provided if A is a bond then n and m is at least 2 and if A is other than a bond then n and m is at least one. These novel adenosines have highly desirable central nervous system and cardiovascular activities and therefore the present invention also includes pharmaceutical compositions and methods of use therefor.
