疟原虫在人类宿主中经历两个生命阶段,无症状的肝脏阶段(LS),随后是具有疾病所有临床表现的血液阶段。在这项研究中,我们研究了一系列的2-炔脂肪酸(2-AFA)的链长在14和18个碳原子之间的双重体外活性对两个生命阶段。2-十八炔酸(2-ODA)是伯氏疟原虫的最佳抑制剂,其IC_(50)为0.34 μg/ml,是对照药物的10倍。在靶点测定研究中,同一化合物以最低的IC_(50)值(分别为0.28-0.80 μg/ml)抑制三种恶性疟原虫FAS-Ⅱ(PfFAS-Ⅱ)延伸酶PfFabI、PfFabZ和PfFabG。分子模拟研究提供了深入了解这一系列的2-AFA的抑制活性的分子方面和相当不同的抑制潜力的可能解释。血液分期P.恶性疟原虫遵循类似的趋势,其中2-ODA成为最具活性的化合物,效力低20倍。分别采用体外和体内方法对2-AFA的全身毒性和肝毒性进行了评价。本研究确定2-ODA是最有前途的抗寄生虫2-AFA,特别是对P。寄生虫
The malaria parasitePlasmodiumgoes through two life stages in the human host, a non-symptomatic liver stage (LS) followed by a blood stage with all clinical manifestation of the disease. In this study, we investigated a series of 2-alkynoic fatty acids (2-AFAs) with chain lengths between 14 and 18 carbon atoms for dual in vitro activity against both life stages. 2-Octadecynoic acid (2-ODA) was identified as the best inhibitor of Plasmodium berghei parasites with ten times higher potency (IC50= 0.34 μg/ml) than the control drug. In target determination studies, the same compound inhibited three Plasmodium falciparum FAS-II (PfFAS-II) elongation enzymesPfFabI,PfFabZ, andPfFabG with the lowest IC50values (0.28–0.80 μg/ml, respectively). Molecular modeling studies provided insights into the molecular aspects underlying the inhibitory activity of this series of 2-AFAs and a likely explanation for the considerably different inhibition potentials. Blood stages ofP. falciparumfollowed a similar trend where 2-ODA emerged as the most active compound, with 20 times less potency. The general toxicity and hepatotoxicity of 2-AFAs were evaluated by in vitro and in vivo methods in mammalian cell lines and zebrafish models, respectively. This study identifies 2-ODA as the most promising antiparasitic 2-AFA, particularly towardsP. bergheiparasites.
