As shown in Table 1, compound of the present invention has obvious anti-microbial activity.
To surveyed G
+bacterium: streptococcus aureus, MRSA, streptococcus pneumoniae, hyopneumoniae suis, staphylococcus epidermidis, faecalis, the streptococcic anti-microbial activity of strangles that II-3, III-3 pair are surveyed are all better than control drug sulfapyridine and valnemulin, especially the anti-microbial activity of methicillin-resistant staphylococcus aureus (MRSA) are significantly better than to control drug valnemulin; What the anti-microbial activity of streptococcus aureus was better than to control drug valnemulin has II-6, III-6, and what the anti-microbial activity of streptococcus pneumoniae was better than to control drug valnemulin has II-3, III-2, III-3, III-6; What the anti-microbial activity of epidermis streptococcus aureus was better than to control drug valnemulin has II-3, III-6, and what hyopneumoniae suis anti-microbial activity was better than to control drug valnemulin has III-3.
G-bacterium to surveyed: the compound ii-6 pair 4 strain G-bacterium of surveying all show medium anti-microbial activity, compound ii-3, except slightly poor to colibacillary anti-microbial activity, surveyed 3 strain G-bacterium to other and are all shown medium anti-microbial activity.
Mycoplasma to surveyed: the anti-microbial activity of II-3, II-6, III-3, the III-6 pair mycoplasma of surveying all quite or be better than control drug valnemulin.
