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.
以下通用公式的化合物在治疗延迟超敏症状方面是有用的。其中X代表键,-CH.sub.2-或氧;Y代表乙烯基,-CH(OH)-,酰基,氧,二价硫,或酰氧基,但当Y为氧,二价硫或酰氧基时,X代表键;A代表由1到6个碳原子组成的直链或支链烷基链,但当Y为乙烯基时,A含有从1到5个碳原子;当Y为酰氧基时,A含有从2到6个碳原子;R^1和R^2中的每一个都选自氢,由1到4个碳原子组成的直链或支链低烷基基团;或具有3到6个碳原子的烯烃基,在除1位置以外的地方具有乙烯不饱和度,并且其药用可接受酸盐。
