    • Novel transient prodrug forms of bio-affecting phenolic compounds are selected from the group consisting of those having the structural formula (I):
      wherein X is O, S or NR 5 wherein R 5 is hydrogen or lower alkyl; R 1 is the mono- or polydehydroxylated residue of a non-steroidal bio-affecting phenol, with the proviso that R' is other than a monohydroxylated or didehydroxylated residue of a phenolic, nuclear dihydroxy natural sympathetic or sympathomimetic amine; R 2 is selected from the group consisting of straight or branched chain alkyl, aryl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aralkyl, alkaryl, aralkenyl, aralkynyl, alkenylaryl, alkynylaryl, (lower acyloxy)alkyl, and carboxyalkyl; 3- to 8-membered, saturated or unsaturated mono-heterocyclic or polyheterocyclic containing from 1 to 3 of any one or more of the heteroatoms N, S or O; and mono- or polysubstituted derivatives of the above; R 3 is hydrogen, lower acyl, cyano, halo(lower alkyl), carbamyl, lower alkylcarbamyl, di(lower alkyl)carbamyl, CH 2 ONO 2 , -CH 2 OCOR 2 or any non-heterocyclic member of the group defined by R 2 above; and n is at least one and equals the total number of phenolic hydroxyl functions comprising the non-steroidal bioaffecting phenol etherified via a R2COXCH(R3)0-moiety; those having the structural formula (II):
      wherein X, R', R 2 and R 3 are as defined above, and n and m are each at least one and the sum of n+m equals the total number of phenolic hydroxyl functions comprising the non-steroidal bioaffecting phenol either etherified via a R 2 COXCH(R 3 )0-moiety or esterified via a R 2 COO-moiety; and the pharmaceutically acceptable acid addition salts, quaternary ammonium salts and N-oxides thereof.
