An objective of the present invention is to provide carbapenem derivatives which have strong antibiotic activity also against MRSA, PRSP, Influenzavirus, and β-lactamase producing bacteria and are stable to DHP-1. The carbapenem derivatives according to the present invention are compounds represented by formulae (I) and (II) or pharmaceutically acceptable salts thereof:
wherein R
1
represents H or methyl, R
2
and R
3
each independently represent H; halogen; substituted or unsubstituted alkyl; cycloalkyl; substituted or unsubstituted alkylcarbonyl; carbamoyl; substituted or unsubstituted aryl; substituted or unsubstituted alkylthio; morpholinyl; alkylsulfonyl; or formyl, n is 0 (zero) to 4, and Hy represents a substituted or unsubstituted monocyclic or bicyclic heterocyclic group.
本发明的目的是提供对MRSA、PRSP、流感病毒和β-内酰胺酶产生菌也具有强抗生素活性且对DHP-1稳定的头孢烯类衍生物。根据本发明,头孢烯类衍生物是以下式(I)和(II)或其药学上可接受的盐所代表的化合物:其中,R1代表氢或甲基,R2和R3各自独立地代表氢、卤素、取代或未取代的烷基、环烷基、取代或未取代的烷基羰基、氨基甲酰基、取代或未取代的芳基、取代或未取代的烷基硫代基、吗啉基、烷基磺酰基或甲酰基,n为0到4,Hy表示取代或未取代的单环或双环杂环基团。
