为寻找高效广谱的防霉抗菌剂，作者设计合成了Ｓ－（２－吡啶－Ｎ－氧化物）－Ｎ，Ｎ′－乙撑异硫脲组溴酸盐。初步抗茵试验表明：所合成的化合物对１１种菌的最低抑制浓度（ＭＩＣ）在０．５－５ｐｐｍ之间，超过目前所使用的工业抗菌剂，具有较好的发展前景。
In order to find efficient and broad spectrum antimicrobial agents, the authors designed and synthesized S- (2-pyridine-N-oxide) -N, N’-ethyleneisothiourea hydrobromide. The preliminary antimicrobial test showed that the minimum inhibitory concentrations (MICs) of the synthesized compounds against 11 kinds of bacteria ranged from 0.5 to 5 ppm, which exceeded the currently used industrial antibacterial agents and had good development prospects.
