Antibacterial oxazolidinone analogues having a N-hydroxyacetyl-substituted seven-membered [1,2,5]triazepane or [1,2,5]oxadiazepane C-ring unit

We synthesized a series of oxazolidinone analogues bearing a N-hydroxyacetyl-substituted [1,2,5]triazepane or [1,2,5]oxadiazepane C-ring unit as homologues of an earlier drug candidate, eperezolid. Several of these compounds exhibited potent in vitro antibacterial activities towards not only Gram-positive, but also Gram-negative and linezolid-resistant pathogens. Compounds 21a and 21b, bearing a thiocarbamate side chain, showed high in vivo activity against methicillin-resistant Staphylococcus aureus SR3637, together with a promising safety profile in terms of weak inhibition of monoamine oxidase and cytochrome P450 isozymes.

OXAZOLIDINONE DERIVATIVE HAVING 7-MEMBERED HETERO RING

The present invention provides a novel oxazolidinone derivative of the formula (I): wherein Ring A is (A-1) a 7-membered monocyclic heterocycle containing three N atoms; (A-2) a 7-membered monocyclic heterocycle containing two N atoms and one O atom; or (A-3) a 7-membered monocyclic heterocycle containing two N atoms and one S atom, SO or SO2, wherein said monocyclic heterocycle is optionally substituted, optionally unsaturated and optionally fused with another ring; X1 is a single bond, or a heteroatom-containing group selected from the group consisting of -O-, -S-, -NR2-, -CO-, -CS-, -CONR3-, -NR4CO-, -SO2NR5-, and -NR6SO2-, wherein R2, R3, R4, R5 and R6 are independently hydrogen or lower alkyl, or lower alkylene or lower alkenylene each optionally interrupted by said heteroatom-containing group; Ring B is optionally substituted carbocycle or optionally substituted heterocycle; and R1 is hydrogen, or an organic residue which is able to bind to the 5-position of the oxazolidinone ring in oxazolidinone antimicrobial agents, pharmaceutically acceptable salts and solvates thereof which are useful as an antibacterial agent.
