[Example 3] [Evaluation of bactericidal activity of compound I (n = 6)] The bactericidal activity of the compound I (n = 6) synthesized in the above example was measured by the "minimum growth inhibitory concentration measurement method" (Nihon Kagaku). The evaluation was carried out by two methods: the standard method of the Japanese Society of Therapeutic Therapy) and the “calcification of carbonic acid coefficient”. (Evaluation of bactericidal property 1—minimum growth inhibitory concentration) An aliquot of a digluconate solution of compound I prepared by the procedure shown in Example 2 was taken, dried in a water bath, and dissolved in acetic anhydride. The concentration was determined by performing a potential difference measurement using an aqueous solution of perchloracetic acid. The 2 gluconate aqueous solution whose concentration was thus determined was diluted with sterile purified water to adjust the concentration, and 1
Dispense into Petri dishes each by ml, and
On agar (Difco) 9 ml was added and mixed well to prepare a culture medium for sensitivity measurement. The compound concentration in the medium was 200 μg / ml and 2 n times (n =
-8 to 2). On the other hand, the bacterial species shown in the left column of Table 1 were added to a culture medium for enrichment (Mueller-Hinton broth (D
ifco)) at 37 ° C. for 24 hours and 10 6 /
The number of bacteria was adjusted to ml, and each was inoculated into a series of culture media for sensitivity measurement. After culturing at 37 ° C. for 24 hours, judgment was performed, and the lowest concentration at which growth was completely inhibited (minimum inhibitory concentration) was measured. The results are shown in Table 1 together with Comparative Examples using chlorohexidine as a bactericide.

The germicidal agent provided by the present invention is comparable to chlorohexidine conventionally used as a germicidal disinfectant in the broad range of the antibacterial spectrum, is excellent in immediate action as compared with chlorohexidine, and furthermore has the bactericidal effect of chlorohexidine. It shows excellent bactericidal properties against Pseudomonas aeruginosa, which is less toxic. Therefore, it is useful as a disinfectant for medical use, especially as a disinfectant for skin and instruments, and a germ impregnated with the solution.
It can be used as cotton, absorbent cotton, pad, etc. In addition, since the practical concentration of a bactericide is usually determined by the bactericidal activity against bacterial species that the bactericide does not work effectively, the bactericide provided by the present invention should be used at a low concentration with less irritation to mucous membranes. It is expected that application to mucous membranes, which is prohibited by chlorohexidine, is also possible.
