摘要:
Ceftolozane Sulfate is a cephalosporin antibacterial agent. Novel, stable, solid forms of the pharmaceutically acceptable sulfate salt of ceftolozane have been isolated via lyophilization. Characterization and identification of these solid forms by XRPD and Raman IR, as well as methods for their preparation and use in pharmaceutical compositions, are described
摘要:
Provided are fluorescent substrates for β-lactamases having general formula (I), in which R is a benzyl, 2-thienylmethyl, or cyanomethyl group; R' is selected from the group consisting of H, physiologically acceptable salts or metal, ester groups, ammonium cations, --CHR2OCO(CH2)nCH3, --CHR2OCOC(CH3)3, acylthiomethyl, acyloxy-alpha-benzyl, deltabutyrolactonyl, methoxycarbonyloxymethyl, phenyl, methylsulphinylmethyl, β-morpholinoethyl, dialkylaminoethyl, and dislkylaminocarbonyloxymethyl, in which R2 is selected from the group consisting of H and lower alkyl; A is selected from the group consisting of S, O, SO, SO2 and CH2; and Z is a donor fluorescent moiety. Also provided are methods of use of the compound of general formula (I).
