Novel substituted heterocyclyl compounds of the formula ##STR1## in which R is a free, esterified or amidated carboxyl group or a free, etherified or esterified hydroxymethyl group, R.sub.1 is an aliphatic, cycloaliphatic, aromatic, araliphatic, heterocyclic or heterocyclic-aliphatic radical, R.sub.2 is hydrogen or an aliphatic radical and Ph is a 1,2-phenylene group containing the radical R.sub.1 -X, and X is lower alkylidene or a direct bond, and pharmaceutically usable salts of compounds of the formula I with salt-forming properties as medicaments, pharmaceutical preparations containing these, their use as medicaments and also novel compounds of the formula I and salts of compounds of the formula I with salt-forming properties, with the proviso that R.sub.1 -X-Ph differs from 1,2-phenylene substituted by methyl in the 4- and/or 5-position when R is carboxyl, carbamyl or hydroxymethyl and R.sub.2 is hydrogen, and pharmaceutically acceptable salts thereof are useful as anti-allergic agents.
公式为##STR1##的新型取代杂环化合物,其中R为自由、酯化或酰胺化羧基或自由、醚化或酯化羟甲基基团,R.sub.1为脂肪族、环状脂肪族、芳香族、芳基脂肪族、杂环或杂环-脂肪基基团,R.sub.2为氢或脂肪基团,Ph为包含基团R.sub.1 -X的1,2-苯基基团,X为较低的烷基亚基或直接键,并且具有盐基形成性质的公式I化合物的药用盐作为药物、含有这些药物的制剂、它们作为药物的使用以及公式I化合物和具有盐基形成性质的化合物的盐,但前提是当R为羧基、氨基甲酰或羟甲基,而R.sub.2为氢时,R.sub.1 -X-Ph与在4-和/或5-位置上被甲基取代的1,2-苯基不同,其药用可接受盐对于治疗过敏具有用处。
