This paper describes an efficient synthesis and the antiparasitic evaluation ofcyclic β-amino acid-containing dipeptides 3.1-3.6 and 4.1-4.5. The antimalarial propertiesof all these dipeptides have been evaluated in vitro against Plasmodium falciparum and invivo against Plasmodium berghai. Compounds 4.4 and 4.5 have been found to be veryeffective in this respect, with IC50 values of 3.87 and 3.64 μg/mL in the in vitro test, while4.5 has also been found to be active in the in vivo evaluation.
本文描述了一种有效的合成方法以及含有环β-
氨基酸的二肽3.1-3.6和4.1-4.5的抗寄生虫评估。所有这些二肽的抗疟疾特性在体外针对恶性疟原虫(Plasmodium falciparum)和在体内针对伯氏疟原虫(Plasmodium berghai)进行了评估。化合物4.4和4.5在这方面被发现非常有效,体外测试的IC50值分别为3.87和3.64 μg/mL,而4.5在体内评估中也表现出活性。
