Indolizino[7,6,5-de]isoquinoline derivatives of the general formula: ##STR1## wherein the symbol R.sub.1 represents a hydrogen atom, the symbol R.sub.2 represents a hydrogen atom, an amino radical, or a straight- or branched-chain alkyl radical which is optionally substituted on a terminal carbon atom by a vinyl, ethynyl, carboxy, alkoxycarbonyl, cyano, dialkoxymethyl, hydroxymethyl, dialkylaminomethyl (the alkyl radicals of which may form with the nitrogen atom to which they are attached a saturated five- or six-membered heterocyclic ring which may contain another hetero-atom selected from nitrogen, oxygen and sulphur, and -- when a second nitrogen atom is present -- may optionally be N-methylated) or trialkylammoniomethyl radical, or R.sub.2 represents a straight- chain alkyl radical which is substituted on the terminal carbon atom by an aminomethyl, alkylaminomethyl or hydroxyalkylaminomethyl radical, and the symbols R.sub.3 and R.sub.4 together form a valence bond, or the symbols R.sub.1 and R.sub.4 together form a valence bond and the symbols R.sub.2 and R.sub.3 together form a grouping of the general formula: ##STR2## wherein the group --OR.sub.5, which represents an alkoxy radical, is attached to the carbon atom situated in the .alpha.-position to the nitrogen atom carrying R.sub.3, the alkyl and alkoxy radicals, or moieties of groups, within the definition of symbols R.sub.2 and R.sub.5 containing from 1 to 4 carbon atoms and their salts are active as antimicrobial agents and antifungal agents, and are suitable for use as local antiseptics.
Indolizino[7,6,5-de]isoquinoline 衍生物的一般公式为:其中符号 R.sub.1 代表氢原子,符号 R.sub.2 代表氢原子、氨基基团,或直链或支链烷基基团,该基团在末端碳原子上可选择性地被乙烯基、乙炔基、羧基、烷氧羰基、氰基、二烷氧甲基、羟甲基、二烷基氨甲基(其中烷基基团可与其连接的氮原子形成饱和的五元或六元杂环环,该环可能含有另一异原子,选自氮、氧和硫,当存在第二个氮原子时,可能选择性地进行 N-甲基化)或三烷基胺基甲基基团,或 R.sub.2 代表直链烷基基团,该基团在末端碳原子上被氨基甲基、烷基氨基甲基或羟基烷基氨基甲基基团取代,符号 R.sub.3 和 R.sub.4 共同形成一个价键,或符号 R.sub.1 和 R.sub.4 共同形成一个价键,符号 R.sub.2 和 R.sub.3 共同形成一般公式的一个分组:其中羟基甲氧基基团 --OR.sub.5 附着在位于携带 R.sub.3 的氮原子的 .alpha.-位置的碳原子上,符号 R.sub.2 和 R.sub.5 的定义中的烷基和烷氧基基团,或基团的部分,含有 1 到 4 个碳原子,它们的盐被用作抗菌剂和抗真菌剂,并适用于用作局部防腐剂。
