an emerging therapeutic tactic for nonsense mutation-related diseases, such as Hurler syndrome, a type of mucopolysaccharidosis. In the present study, novel triaryl derivatives were synthesized and their readthrough-inducing activities were evaluated by a luciferase reporter assay with a partial α-L-iduronidase (IDUA) DNA sequence containing the Q70X nonsense mutation found in Hurler syndrome and by
通读机制跳过过早终止密码子并恢复有缺陷的酶的生物合成,是一种新兴的治疗无义突变相关疾病的策略,例如胡勒综合征(一种粘多糖贮积症)。在本研究中,合成了新型三芳基衍生物,并通过荧光素酶报告基因测定法评估了其通读诱导活性,其中使用包含 Hurler 综合征中发现的 Q70X 无义突变的部分 α-L-艾杜糖醛酸酶 (IDUA) DNA 序列,并通过测量该酶来评估其通读诱导活性。转染突变 IDUA 基因的 IDUA 敲除细胞的活性。KY-516是临床使用的ataluren左环间位羧基转化为对位氨磺酰氨基、中心环转化为三唑、右环转化为氰基苯的代表性化合物,表现出最有效的通读性-Q70X/荧光素酶报告基因测定中的诱导活性。在 Q70X 突变 IDUA 转基因细胞中,KY-516 在 0.1 µM 时显着提高酶活性。大鼠口服KY-516(10 mg/kg)后,KY-516的最高血浆浓度超过5 µM。这些结果表明
