was investigated in-silico as a new molecular therapeutic target for these compounds. All compounds showed potential interactions with the catalytic residues. These results showed that acridine-9(10H)-one derivatives, in particular compounds II, VII, VIII and IX hold promise in the development of therapeutic agents against these free-living amoebae.
致病性A. castellanii和N. fowleri是机会主义的自由生活变形虫。棘阿米巴属 是肉芽肿性阿米巴脑炎 (GAE) 和阿米巴角膜炎 (AK) 的病原体,而福氏耐格里虫 ( Naegleria fowleri )引起非常罕见但严重的脑部感染,称为原发性阿米巴脑膜脑炎 (PAM)。吖啶酮是一种重要的杂环支架,合成和天然衍生物都显示出各种有价值的生物学特性。在本研究中,合成了 10 种合成吖啶酮衍生物 ( IX ),并针对两种变形虫进行了体外抗变形虫和杀囊肿活性的评估. 此外,还在体外进行了脱囊作用、包囊作用、细胞毒性、宿主细胞致病性。此外,对这些化合物与N. fowleri的三种组织蛋白酶 B 旁系同源酶进行了分子对接研究,以预测与病原体的可能对接模式。化合物VII对A. castellanii显示出有效的抗阿米巴活性,IC 50 为53.46 µg/mL,而化合物IX在体外对 N
