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.
公开了新型的碳青霉烯衍生物,其特征在于2-取代基的公式为##STR1##,其中A代表C.sub.1-C.sub.6的直链或支链亚烷基;R.sup.5代表可选地取代的脂肪族、环脂肪族、环脂肪族-脂肪族、芳香族、芳脂肪族、杂芳族、杂芳脂肪族、杂环基或杂环基-脂肪族基团;而##STR2##代表一个含氮的芳香杂环,通过亚烷基A与环上的碳原子相连,并通过取代基R.sup.5进行季铵化。这样的衍生物作为强效的抗菌剂是有用的。
