摘要:
The present invention relates to antibacterial agents of the carbapenem class, in which the 2-position sidechain is characterized by a phenanthridine moiety typically having a substituent attached to the nitrogen of the phenanthridine and substituted at other positions by various neutral substituents. When there is substitution on the nitrogen of the phenathridine moiety that nitrogen is a charged quaternary nitrogen.
摘要:
Carbapenem intermediates having the formula: ##STR1## where Z is ##STR2## M is a removable protecting group for carboxy and P' is a removable protecting group for hydroxy, are useful intermediates for preparing antibacterial agents, especially with respect to activity against methicillin resistant Staphylococcus aureus (MRSA).
摘要:
The present invention relates to tricyclic carbapenem antibacterial agents in which the carbapenem nucleus is fused to a 6 membered carbocyclic ring. The compound is further substituted with various substituent groups including at least one cationic group. The compounds are represented by formula I: Pharmaceutical compositions and methods of use are also included.
