实施例3、DHA胺类衍生物和DHA唑类衍生物的抗疟活性测试
DHA胺类衍生物和DHA唑类衍生物的抗疟活性委托美国礼来公司Open InnovationDrug Discovery(OIDD)program进行测试，包括目标化合物对恶性疟原虫(Plasmodiumfalciparum)DD2株的抑制率、对人肝癌细胞HepG2中伯氏疟原虫(P.berghei)红外期(EEF)的抑制率以及对人肝癌细胞HepG2的毒性，首先进行单浓度初筛(Primary SP)，然后对初步筛选出的潜力分子进行多浓度测试(Primary CRC)。结果见表5,6。
表5 DHA胺类衍生物的抗疟活性测试结果
从表5看出，测试的18个DHA胺类衍生物对恶性疟原虫有很强的抑制活性(抑制率85％-121％)，其中化合物1e在2μM测试浓度下的抑制率达到106％，化合物1c、2a-2、2b-2在12.5μM测试浓度下的抑制率超过100％；DHA胺类衍生物对伯氏疟原虫红外期的抑制活性相对低一些(13％-82％)，其中化合物1h、2a-1、2a-5、2b-1、2b-4、2b-5的抑制率在65％-82％；DHA胺类衍生物的细胞毒性很低(抑制率几乎都在±20％)。整体来看，DHA胺类衍生物具有高活性、低毒性的特点。
表6 DHA唑类衍生物的抗疟活性测试结果
从表6可以看出,测试的40个DHA唑类衍生物中有30个化合物在测试浓度下对恶性疟原虫的抑制率超过90％；DHA唑类衍生物对伯氏疟原虫红外期的抑制活性相对低一些，化合物3a-1,3a-3,3a-6,3b-1,4a-3,4b-1,5b-1,5b-2,5b-5,5b-6的抑制率在60％-88％之间；化合物3a-3,3a-6,3b-1,5b-1,5b-6对恶性疟原虫和伯氏疟原虫红外期的抑制活性都很强；特别地，几乎所有目标化合物都表现出较低的细胞毒性，抑制率在-5％～20％。整体来看，DHA唑类衍生物对疟原虫具有非常强的抑制作用,可作为药物进一步开发。
最后说明的是，以上优选实施例仅用以说明本发明的技术方案而非限制，尽管通过上述优选实施例已经对本发明进行了详细的描述，但本领域技术人员应当理解，可以在形式上和细节上对其作出各种各样的改变，而不偏离本发明权利要求书所限定的范围。
