- the frequency of appearance of abnormal cells after treatment with 100 g / inl of the test compound was determined. The frequency of abnormal cells was less than 10% for both A and control compound B.
- Hartley male guinea pigs were intravenously administered 1 Omg / kg of the test compound, and immediately afterward, UVA was applied to the back skin for 90 minutes, and erythema at the ultraviolet irradiation site was observed 24 hours after irradiation.
- Table 2 shows the number of guinea pigs showing erythema.
- Compound 1 of the present invention did not show phototoxicity, but control compound A showed phototoxicity in more than half (3 out of 5).
- Wistar male rats (weight: 180-220 g) were pentobarbital sodium
- the rats were anesthetized with 45 mg / kg, ip, and the rat head was fixed on a stereotaxic apparatus.
- a stainless steel tube with a diameter of 0.6 ⁇ for intraventricular administration was placed 1.5mm above the left ventricle (A: 6.2, R: 1.0, H: + l.0).
- the guide cannula was fixed with dental cement, covered with a 3 mm diameter stainless steel tube, and 10,000 units of penicillin G potassium was subcutaneously administered to infect the infection. I prevented it. Rats were tested after a recovery period of several days postoperatively.
- humbufun 5 O mg / kg was intraperitoneally administered, a polyethylene tube was connected, and a guide was given to inject into the correct location of the ventricle (H: +1.0).
- a test compound (20 ug) was administered intracerebroventricularly 30 minutes after the administration of fenbufen using a stainless steel tube having a diameter of 0.3 mm prepared to be 1.5 mm longer than the force neuron. Observed for the appearance of climbing for more than 4 hours. After the experiment was completed, 10/1 1% Evans blue was injected into the ventricle of each rat, and the brain was cut to confirm its position.
- Table 2 shows the number of rats that induced cramping. Compound 1 of the present invention did not induce cramping, but control compounds A and B induced climbing in all cases (3 cases each).
- the compound (I) of the present invention has an excellent antibacterial activity and does not cause any side effects such as phototoxicity, chromosomal aberration induction, and spasticity induction, and is therefore extremely useful as an antibacterial agent. Further, the compound (II) of the present invention is useful for the efficient production of the above compound (I).
