Also, the oxazolidinone derivative of the invention has a potent antimicrobial activity against gram-positive bacteria and gram-negative bacteria. Especially, the compound exhibits antimicrobial activity with wide spectrum against drug-resistant gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin resistant enterococcus (VRE), penicillin resistant pneumococcus (PRSP). More preferably, the compound of the invention is effective against linezolid resistant (LZD-R) organisms. The compound of the invention more preferably shows good solubility or absorbability, which allows administration by injection. Still more preferably, the compound of the invention reduces the side-effects concerned in conventional antimicrobial agents (e.g., linezolid), such as bone marrow suppression, monoamine oxidase (MAO) inhibiting activity, neurotoxicity. Decreased MAO inhibition is preferred because side-effects such as metabolism suppression of dopamine, serotonin, etc., blood pressure elevation, agitation, etc. are concerned by such inhibition. Additionally, preferred compound of the invention also shows good profiles in pharmacokinetics such as CYP inhibition, PK profile, plasma stability.
Also, the compound of the invention, wherein triazacycloheptane skeleton or oxadiazepane skeleton is connected to quinolone skeleton, shows a potent antimicrobial activity against various bacteria. Especially, the compound shows antimicrobial activity equal to or more (e.g., more than 4 times) than commercial newquinolone antimicrobial drug (e.g., ciprofloxacin, gatifloxacin, moxifloxacin) against various bacteria including VRE (vancomycin resistant enterococcus), MRSA (methicillin-resistant Staphylococcus aureus).
Thus, by having triazacycloheptane skeleton, oxadiazepane skeleton or similar structure thereof as a partial structure, the compound of the invention remarkably improves its pharmaceutical activity, pharmacokinetics and/or side-effects and very useful as a pharmaceutical compound.
Also, a synthetic intermediate of the invention having triazacycloheptane skeleton, oxadiazepane skeleton is useful for the production of various pharmaceutical compounds including antimicrobial agent.

The compounds of the above Examples were tested for antimicrobial activity.
(Test Method)
Minimal inhibitory concentration (MIC: μg/ml) against different strains of bacteria was assayed according to the standard method recommended by CLSI (clinical and laboratory standards institute). Samples were prepared from test compound solution in DMSO (1280 μg/mL) by two fold (serial) dilution with DMSO. The sample was added to bacteria suspension at the concentration of 5%, and MIC was determined. Mueller Hinton Broth, which has been adjusted for cation concentration, was used for culture media in this test. The inoculation concentration was about 5×105 CFU/mL.
(Result)
The compound of the invention showed strong antimicrobial activity, which was comparable to or more (e.g., four times or more) than linezolid and vancomycin, against various strains of bacteria, such as VRE (vancomycin resistance enterococcus), VISA (vancomycin-intermediate Staphylococcus aureus). For example, the MIC value (μg/mL) of the compound of the working examples (e.g., Examples 81, 82, 83, 84, 85, 86 and 91) was equal to or less than 1, against bacteria such as S. aureus FDA 209P, S. aureus smith, S. aureus ATCC 700787, E. faecalis ATCC 29212, E. faecalis SR7914, E. faecium SR7917.
