There is a need to develop new antischistosomal compounds when the only available therapeutic agents
praziquantel large-scale used in the world. A series of novel aminoalcohol derivatives bearing 4-phenylphenol moiety
were designed and synthesized. The structures of all the newly synthesized compounds were identified by elemental
analysis, 1H-NMR, 13C-NMR and LC-MS. Their biological activities were evaluated against Schistosoma japonicum in
mice by an oral route. Among these compounds, in vivo, at concentrations 400mg/kg of mouse, compound 1-(biphenyl-4’-
yloxy)-3-(1’-(3’,4’-difluorophenyl)ethylamino)propan-2-ol (3j) produced the highest activity with 93.0% deparasitization.
These compounds may find usefulness in the discovery and development of new antischistosomal drugs.
目前全球大规模使用的唯一抗血吸虫治疗药物是吡喹酮,因此有必要开发新的抗血吸虫化合物。设计并合成了一系列含有4-苯基苯酚结构单元的氨基醇衍生物。所有新合成的化合物的结构通过元素分析、1H-NMR、13C-NMR和LC-MS进行了鉴定。它们的生物活性通过口服途径在小鼠中针对日本血吸虫进行了评估。在这些化合物中,以每千克体重400毫克的浓度给药时,1-(联苯-4'-基氧)-3-(1'-(3',4'-二氟苯基)乙氨基)丙-2-醇(3j)表现出最高的活性,去寄生效果达到93.0%。这些化合物在发现和开发新的抗血吸虫药物方面可能具有潜在的用途。
