摘要:
The present invention relates to carbapenem antibacterial agents of the formula I: as well as salts and hydrates thereof. Pharmaceutical compositions and methods of treatment are also included wherein X is present or absent, when present, represents a members selected from the group consisting of: CH2, C(R)2, C═CR2, O, S(O)x, with x equal to 0, 1 or 2; C(O), C(O)O, OC(O) and NR—.
摘要:
The present invention relates to penem antibacterial agents in which the releaseable liphophilic aromatic side-chain, tethered to the carbapenem nucleus via a methylene linker, necessary for anti-MRSA activity replaces the non-releaseable liphophilic side-chains found in 2-aryl and 2-benzothiazolylthio carbapenem compounds. 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.
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.
摘要:
Disclosed are antibiotic 7-(substituted methyl) cephalosporins, derivatives and nuclear analogues thereof; wherein the methyl substituent is, inter alia, hydroxyl, ketonic oxygen, imino nitrogen, amino or thio. Also disclosed are processes for the preparation of such compounds and their pharmaceutically acceptable salt, ester and amide derivatives; pharmaceutical compositions comprising such compounds; and methods of treatment comprising administering such compounds and compositions when an antibiotic effect is indicated.
摘要:

The compounds are represented by formula I: wherein Z represents trans-ethenediyl or ethynediyl. Pharmaceutical compositions and methods of use are also included.
摘要:
The present invention relates to carbapenem antibacterial agents in which the carbapenem nucleus is substituted at the 2-position with an iodo-substituted phenyl linked through a CH2—O— group. The compounds of the invention are represented by formula I: wherein A represent O, S or —CH2— attached at position 3, 4 or 6; Q is selected from the group consisting of: &agr; represents O, S or NRs; &bgr;, &dgr;, &ggr;, &mgr; and &sgr; represent CRt, N or N+Rs, provided that no more than one of &bgr;, &dgr;, &ggr;, &mgr; and &sgr; is N+Rs, balanced by L− or a carboxylate anion. Salts and hydrates thereof are included. The iodo-substituted phenyl ring is further substituted with various substituent groups including at least one cationic group. Pharmaceutical compositions and methods of treatment are also included.
