[Objective] An objective of the present invention is to provide compounds that are effective against various resistant bacteria which cause current clinical problems, for example, pneumococci including penicillin resistant
Streptococcus pneumoneae
(PRSP),
Haemophilus influenzae
including bata-lactamase-nonproducing ampicillin-resistant
Haemophilus influenzae
(BLNAR), and
Moraxella
(
Branhamella
)
catarrhalis.
[Structure] The present invention provides 2-ethenylthio-based carbapenem derivatives represented by the formula (I) or pharmaceutically acceptable salts thereof that are effective, for example, against pneumococci including penicillin resistant
Streptococcus
pneumoneae (PRSP),
Haemophilus influenzae
including beta-lactamase-nonproducing ampicillin-resistant
Haemophilus influenzae
(BLNAR), and
Moraxella
(Branhamella) catarrhalis:
                            【目的】本发明的目的是提供一种对于各种耐药细菌有效的化合物,这些细菌引起当前的临床问题,例如包括
青霉素耐药的肺炎链球菌(PR
SP)、不产β-内酰胺酶的
氨苄西林耐药的流感嗜血杆菌(BLNAR)和卡他莫拉菌(布兰哈氏菌)等。 
【结构】本发明提供以2-
乙烯硫基为基础的碳青霉烯衍
生物,其表示为式(I)或其药学上可接受的盐,例如,对于包括
青霉素耐药的肺炎链球菌(PR
SP)、不产β-内酰胺酶的
氨苄西林耐药的流感嗜血杆菌(BLNAR)和卡他莫拉菌(布兰哈氏菌)等细菌具有有效性。
