among them linear di-, tri-, tetra- and pentapeptides and their cyclic analogs. In an attempt to find dipeptides with antimalarial activities we show that linear and cyclic dipeptides, the latter known as diketopiperazines, still retain the fundamental core to preserve antimalarial activity. Thirteen linear dipeptides and ten diketopiperazines were investigated. Eight linear dipeptides showed IC50
几种天然和合成多肽具有重要的抗疟活性。还已经描述了具有有效抗疟活性的较短的肽,其中包括线性二肽,三肽,四肽和五肽及其环状类似物。为了找到具有抗疟疾活性的二肽,我们发现线性和环状二肽(后者被称为二酮哌嗪)仍然保留了保持抗疟疾活性的基本核心。研究了十三种线性二肽和十种二酮哌嗪。在伯氏疟原虫裂殖体培养物中,八种线性二肽的IC 50值在2.78至7.07μM之间,而八种二酮哌嗪也有活性,IC 50值在2.26至4.26μM之间。
