Chromone derivatives of the formula: ##STR1## wherein R.sup.1 is alkoxy, an N,S-containing heterocyclic group or aryloxy in which heterocyclic group may be substituted with halogen or acyl, and aryl may be substituted with amino, alkylamino, acylamino, nitro or alkylenedioxy; R.sup.2 is alkylene; R.sup.3 is hydroxy, alkoxy or a group of the formula ##STR2## in which R.sup.4 is hydrogen, R.sup.5 is hydroxy or amino or R.sup.4 and R.sup.5 means taken together with the adjacent nitrogen atom, piperazinyl substituted with alkyl or hydroxyalkyl; provided that when R.sup.3 is hydroxy or alkoxy, R.sup.1 is an N,S-containing heterocyclic group or aryloxy in which heterocyclic group is substituted with halogen or acyl, and aryl is substituted with amino, alkylamino, acylamino, nitro or alkylenedioxy, and nontoxic, pharmaceutically acceptable salt thereof. These compounds are useful as anti-allergic agents.
化合物的公式为:##STR1## 其中,R.sup.1为烷氧基、含氮、硫的杂环基或芳氧基,其中杂环基可以用卤素或酰基取代,芳基可以用氨基、烷基氨基、酰基氨基、硝基或烷基二氧取代;R.sup.2为烷基;R.sup.3为羟基、烷氧基或公式##STR2##中的一种,其中R.sup.4为氢,R.sup.5为羟基或氨基,或者R.sup.4和R.sup.5与相邻的氮原子一起,用烷基或羟基烷基取代的哌嗪基;但是当R.sup.3为羟基或烷氧基时,R.sup.1为含氮、硫的杂环基或芳氧基,其中杂环基被卤素或酰基取代,芳基被氨基、烷基氨基、酰基氨基、硝基或烷基二氧取代,以及其无毒、药学上可接受的盐。这些化合物可用作抗过敏剂。
