We comprehensively investigated the effects of substitution of the benzyl group in S-benzylisothiourea derivatives on antibacterial activity, because we found previously that some substitutions enhanced it. A 2,4-Cl2-derivative was found to be the most effective compound, it was stronger than the original one in Gram-negative rod shaped-bacteria such as Escherichia coli and Salmonella typhimurium.
我们全面研究了S-苄基异
硫脲衍
生物中苄基取代基对抗菌活性的影响,因为我们此前发现某些取代基能增强这一活性。我们发现2,4-二
氯衍
生物是最有效的化合物,它在革兰氏阴性杆菌如大肠杆菌和鼠伤寒沙门氏菌中的抗菌活性强于原化合物。
