Substituted anthranilamides of the formula ##STR1## in which R.sub.1 is hydrogen or an aliphatic, cycloaliphatic or cycloaliphatic-aliphatic hydrocarbon radical, R.sub.2 is hydrogen, lower alkyl, lower alkoxy, halogen or trifluoromethyl, R.sub.3 is hydrogen or an aliphatic or substituted or unsubstituted araliphatic or heteroaryl-aliphatic hydrocarbon radical and alk and alk' are identical or different lower alkylene radicals which separate the nitrogen atoms by 2 or 3 carbon atoms, and salts thereof, possess analgesic, anti-inflammatory and anti-allergic properties and may be used as active ingredients of analgesic, anti-inflammatory and anti-allergic pharmaceuticals. They are prepared, for example, by reacting an acid of the formula ##STR2## or a reactive functional derivative thereof, with an amine of the formula ##STR3## or a reactive derivative or salt thereof.
公式为##STR1##的取代基蒽酰胺,其中R.sub.1是氢或脂肪,环脂肪或环脂肪-脂肪烃基,R.sub.2是氢,低级烷基,低级烷氧基,卤素或三氟甲基,R.sub.3是氢或脂肪或取代或未取代的芳基脂肪或杂环芳基-脂肪烃基,而且alk和alk'是相同或不同的低级烷基烃基,它们通过2或3个碳原子分离氮原子,并且它们的盐具有镇痛,抗炎和抗过敏性质,可以用作镇痛,抗炎和抗过敏药物的活性成分。例如,它们可以通过将公式为##STR2##的酸或反应性官能衍生物与公式为##STR3##的胺或反应性衍生物或盐反应来制备。
