Synthesis and antimicrobial properties of cephalosporin derivatives substituted on the C(7) nitrogen with arylmethyloxyimino or arylmethyloxyamino alkanoyl groups
7-aminocephalosporanic acid (7-ACA) derivatives substituted on the C(7) nitrogen with 2-(arylmethyloxyimino)propionyl (3a-f), 2-(arylmethyloxyamino)propionyl (4a-d) and (arylmethyloxyamino)acetyl (2a-d) moieties were synthesized by reaction of the appropriate acylating agents with 7-ACA protected as a t-butyl ester, followed by removal of the t-butyl protecting group. The new compounds, tested in vitro for their antimicrobial

A series of sulfonylatedhydroxamates were synthesized and evaluated as dual inhibitors of both human carbonicanhydrases (hCAs) and matrixmetalloproteinases (MMPs), two metalloenzyme families involved in carcinogenesis and tumor invasion processes. The new derivatives were tested on three CAisozymes, the cytosolic isozymesI and II, and the transmembrane, tumor-associated isozyme IX, and also on
