Disclosed are novel carbapenem derivatives characterized by a 2-substituent of the formula ##STR1## in which A represents a C.sub.1 -C.sub.6 straight or branched chain alkylene group; R.sup.5 represents an optionally substituted aliphatic, cycloaliphatic, cycloaliphatic-aliphatic, aryl, araliphatic, heteroaryl, heteroaraliphatic, heterocyclyl or heterocyclyl-aliphatic radial and ##STR2## represents a nitrogen-containing aromatic heterocycle attached to the alkylene group A at a ring carbon atom and quaternized by substituent R.sup.5. Such derivatives are useful as potent antibacterial agents.
本发明涉及新型碳青霉烯衍生物,其特征在于具有如下式中的2-取代基:##STR1## 其中,A代表C.sub.1-C.sub.6直链或支链烷基;R.sup.5代表一个可选择性取代的脂肪族、环脂族、环脂族-脂肪族、芳香族、芳基脂肪族、杂环芳族、杂环芳基脂肪族、杂环基或杂环基-脂肪族基团;而##STR2##代表一个含氮芳香杂环,连接到环烷基A上的一个环碳原子,并被基团R.sup.5季铵化。这样的衍生物可用作强效抗菌剂。
