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 NR5 wherein R5 is hydrogen or lower alkyl; R1 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; R2 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; R3 is hydrogen, lower acyl, cyano, halo(lower alkyl), carbamyl, lower alkylcarbamyl, di(lower alkyl)carbamyl, CH2ONO2, -CH2OCOR2 or any non-heterocyclic member of the group defined by R2 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', R2 and R3 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 R2COXCH(R3)0-moiety or esterified via a R2COO-moiety; and the pharmaceutically acceptable acid addition salts, quaternary ammonium salts and N-oxides thereof.
生物效应酚类化合物的新型瞬效原药形式选自具有结构式(I)的化合物组成的组:
其中 X 是 O、S 或 NR5,其中 R5 是氢或低级烷基;R1 是非类固醇生物效应酚的单羟基或多羟基残基,但 R' 不是酚、核二羟基天然交感胺或拟交感胺的单羟基或双羟基残基;R2 选自直链或支链烷基、芳基、环烷基、烯基、环烯基、炔基、芳烷基、烷芳基、芳烯基、芳炔基、烯芳基、炔芳基、(低级酰氧基)烷基和羧基烷基组成的组;R3 是氢、低级酰基、氰基、卤代(低级烷基)、氨甲酰基、低级烷基氨甲酰 基、二(低级烷基)氨甲酰基、CH2ONO2、-CH2OCOR2 或上述 R2 定义的基团中的任何非杂环成员;且 n 至少为 1,等于通过 R2COXCH(R3)0 子代醚化的非甾体生物作用酚所包含的酚羟基官能团的总数;具有结构式(II)的酚羟基官能团:
其中 X、R'、R2 和 R3 如上文所定义,n 和 m 至少各为 1,且 n+m 之和等于非甾体类生物效应酚通过 R2COXCH(R3)0 子键醚化或通过 R2COO 子键酯化的酚羟基官能团的总数;及其药学上可接受的酸加成盐、季铵盐和 N-氧化物。
