An objective of the present invention is to provide compounds of formula (I) or their pharmacologically acceptable salts or solvates wherein A represents aryl while R1 represents a five- or six-membered monocyclic heterocyclic group, or A represents a four- to six-membered monocyclic heterocyclic group while R1 represents aryl or a five- or six-membered monocyclic heterocyclic group; R2 represents a hydrogen atom or C1-6 alkyl; R3 represents C1-6 alkyl or C3-6 cycloalkyl-C1-4 alkyl; R4, R5, and R6 represent a hydrogen atom; R7 represents C1-6 alkyl; and m is 1 to 3. The compounds are novel lincosamide derivatives that have a potent activity against resistant Streptococcus pneumoniae. Further, the compounds are usable as antimicrobial agents and are useful for preventing or treating bacterial infectious diseases.
本发明的目的是提供式(I)化合物或其药理学上可接受的盐或溶液,其中 A 代表芳基,而 R1 代表五元或六元单环杂环基团,或 A 代表四至六元单环杂环基团,而 R1 代表芳基或五元或六元单环杂环基团;R2代表氢原子或C1-6烷基;R3代表C1-6烷基或C3-6环烷基-C1-4烷基;R4、R5和R6代表氢原子;R7代表C1-6烷基;m为1至3。这些化合物是新型林可酰胺衍生物,对耐药性肺炎链球菌具有强效活性。此外,这些化合物还可用作抗菌剂,用于预防或治疗细菌感染性疾病。
