Abstract: The present invention provides a pharmaceutical composition useful for treating bacterial infections in humans and animals which comprises administering to a human or animal in need thereof, an antibacterially effective combination of a ?-lactam antibiotic and an inhibitor of any bacterial peptidoglycan biosynthesis enzyme, especially GlmU, GlmU, MurA, MurB, MurC, MurD, MurE, MurF, MurG, MraY, and UppS.

Abstract: Dosage forms or pharmaceutical compositions comprise a compound having the structure of Formula IV: wherein n is a non-negative integer; wherein each Z is an oxazolidinone-containing moiety having antibiotic activity in vivo upon cleaving, wherein M is independently OR1 or NR1R2; wherein R1 and R2 are independently selected from the group consisting of H, an optionally-substituted hydrocarbyl residue or a pharmaceutically acceptable cation; wherein the compound in the dosage form or a pharmaceutical composition is present in an amount effective for treating or preventing an antibacterial infection in a mammalian subject. Methods of preparing and using these dosage forms or pharmaceutical compositions are also disclosed.

Abstract: A crystalline form of crystalline (R)-3-(4-(2-(2-methyltetrazol-5-yl)-pyridin-5-yl)-3-fluorophenyl)-5-hydroxymethyl oxazolidin-2-one dihydrogen phosphate, methods of making the crystalline form and pharmaceutical compositions comprising the crystalline form are useful antibiotics. Further, the derivatives of the present invention may exert potent antibacterial activity versus various human and animal pathogens, including Gram-positive bacteria such as Staphylococi, Enterococci and Streptococi, anaerobic microorganisms such as Bacteroides and Clostridia, and acid-resistant microorganisms such as Mycobacterium tuberculosis and Mycobacterium avium. Accordingly, the compositions comprising the crystalline form may be used in antibiotics.

Abstract: Methods of preparing a class of oxazolidinones useful to impede bacterial growth are disclosed.

Abstract: The present invention is directed to compounds of formula I, pharmaceutical compositions comprising the compounds, and methods for making and using the inventive compounds.
