Compounds of the following general formula are useful in the treatment of conditions of delayed hypersensitivity. ##SPC1## Wherein X represents a bond, --CH.sub.2 --, or oxygen; Y represents a vinlyene group, --CH(OH)--, carbonyl, oxygen, divalent sulfur, or carbonyloxy with the proviso that when Y is oxygen, divalent sulfur or carbonyloxy, X represents a bond; A represents a straight or branched alkylene chain of from 1 to 6 carbon atoms with the proviso that when Y is vinlyene, A contains from 1 to 5 carbon atoms; and with the proviso that when Y is carbonyloxy, A contains from 2 to 6 carbon atoms; each of R.sup.1 and R.sup.2 is selected from hydrogen, a straight or branched lower alkyl group of from 1 to 4 carbon atoms; or alkenyl of 3 to 6 carbon atoms having the vinyl unsaturation in other than the 1-position, and pharmaceutically acceptable acid addition salts thereof.
以下通式的化合物在治疗迟发型超敏反应方面有用。 ##SPC1## 其中,X代表键,--CH.sub.2 --或氧; Y代表vinlyene基团,--CH(OH)--,羰基,氧,二价硫或羰氧基,但当Y为氧,二价硫或羰氧基时,X表示键; A代表1至6个碳原子的直链或支链烷基链,但当Y为vinlyene时,A含有1至5个碳原子; 当Y为羰氧基时,A含有2至6个碳原子; R1和R2中的每一个都选择自1至4个碳原子的直链或支链低烷基; 或3至6个碳原子的烯丙基,其乙烯不饱和度在1-位以外,并且其药学上可接受的酸加盐。
