A series of hydroxyethylamines has been synthesized from the reaction of (2S,3S )Boc-phenylalanine epoxide with alkyl amines in good yields and evaluated for their in vivo antimalarial activity in mice. Compound 4g presented better activity then the reference artesunate in percentage of inhibition of parasitemia in treated P. berghei-infected mice and compare to the activity of artesunate in the survival
从(2S,3S)Boc-苯丙氨酸环氧化物与烷基胺的反应中,以高收率合成了一系列羟乙胺,并对其在小鼠体内的抗疟活性进行了评估。在治疗的伯氏疟原虫感染的小鼠中,化合物4g表现出比参比青蒿琥酯更好的活性,其抑制寄生虫病的百分比,并且与感染后14天青蒿琥酯在小鼠存活中的活性相比。在成瘾中,未发现溶血活性,这表明对寄生虫病的抑制归因于抗疟疾活性。化合物4g抑制了向裂殖体的分化,表明寄生虫代谢可能是4g的靶标。这些结果表明,这类化合物对于新抗疟药的开发具有广阔的前景。
