2. Description of the Related Art In recent years, the frequency of isolation of Gram-positive bacteria has increased in clinical settings, and the frequency of isolation of methicillin-resistant Staphylococcus aureus (hereinafter abbreviated as MRSA) has increased remarkably. MRSA infections are generally extremely intractable, and their causes include a decrease in the immune capacity of patients and the lack of effective antibacterial agents. At present, vancomycin is widely used as a therapeutic drug for MRSA infection, but it may cause serious side effects and is difficult to use for all MRSA infections. Further, since vancomycin-resistant bacteria tend to increase, a new drug effective for MRSA is desired.

[0003] Cephalosporin antibacterial agents have broad antibacterial activity against Gram-positive and Gram-negative bacteria and have been widely used in clinical settings as highly safe drugs. However, these cephalosporin compounds have no antibacterial activity against MRSA and cannot be used for treating MRSA infections, which have been increasing in recent years.

After stirring at room temperature for 0.5 hour, the precipitate was collected by filtration, washed with water and washed with methanol to obtain a white powder. The obtained powder is dissolved in N, N-dimethylformamide (50.0 ml), silica gel (C-200) is added, and the mixture is dried under reduced pressure. The residue is layered on silica gel column chromatography (C-400) and eluted with methylene chloride for purification. Fractions containing the desired product were concentrated under reduced pressure to give 5.67 g of the title compound as a white powder (yield 79
%).

Sodium 4-carboxylate Trifluoroacetic acid (1 ml) was added to a solution of the compound of Example 9 (246 mg, 238 μmol) in anisole (1 ml), and the mixture was stirred at room temperature for 1 hour. The reaction solution was poured into diisopropyl ether (50 ml), and the precipitated crystals were collected by filtration and air dried. After suspending this in water (5 ml), adjust the pH to 7.2 with saturated aqueous sodium hydrogen carbonate solution, and add to adsorbent HP-20 [water → water-acetonitrile (20: 1) → water-acetonitrile (4: 1)]. After purification,

This was dissolved in anisole (1 ml), trifluoroacetic acid (1 ml) was added, and the mixture was stirred at room temperature for 1 hr. The reaction solution was poured into diisopropyl ether (50 ml), and the precipitated crystals were collected by filtration and air dried. After suspending this in water (5 ml), the pH was adjusted to 7.4 with a saturated aqueous sodium hydrogen carbonate solution, and the adsorbent HP-20 was used.
After purification with [water → water-acetonitrile (20: 1) → water-acetonitrile (4: 1)], lyophilization gave 56.7 mg of the title compound as a yellowish white powder (yield 20%).
