新的提亚衍生物通过抑制酸4-酶IIIβ (PI4KIIIβ) 来表现出对人类犀病毒 (RV) 的强有力的抗病毒活性. 化合物2e (KR-27452) 是开发广泛的抗RV疗法的有希望的候选物.
科学领域:
- 药用化学 医学化学
- 病毒学 病毒学
- 药物发现 药物发现 药物发现
背景情况:
- 人类犀利病毒 (RVs) 是导致呼吸道感染的重要原因.
- 目前没有批准的抗病毒疗法用于VR感染.
- 酸丁醇4-酶IIIβ (PI4KIIIβ) 是RNA病毒利用的宿主标,包括RVs.
研究的目的:
- 设计,合成和评估2-amido-3-aryl-4-methyl-thiazole衍生物作为潜在的抗病毒药物.
- 评估这些化合物对PI4KIIIβ的抑制活性.
- 为了确定用于开发广谱抗RV疗法的化合物.
主要方法:
- 合成2 - 阿米多 - 3 - 阿里尔 - 4 - 甲基 - 醇衍生物.
- 在体外对抗RVs (A,B和C组) 和Coxsackievirus的抗病毒活性进行了评估.
- 细胞毒性和选择性指数的评估.
- 分子动力学模拟以了解与PI4KIIIβ的结合相互作用.
- 在体外肝脏微小体测定代谢稳定性.
- 在老鼠中进行的药理动力学研究.
主要成果:
- 化合物2e和2f对A组和B组RVs (EC50=0.060.843μM) 和RV-C15 (EC50=0.118和0.059μM,分别) 显示出强烈的活性.
- 这些化合物表现出低细胞毒性 (CC50 ≥ 100μM),导致高选择性指数.
- 化合物2e和2f选择性地抑制了PI4KIIIβ而不是PI4KIIIα,并减少了传染性病毒的产生.
- 分子动力学模拟显示,2e和2f通过键和疏水相互作用稳定地与PI4KIIIβ结合.
- 药理动力学研究显示,大鼠的代谢稳定性中等,半衰期有利,口服生物可用性好 (52.4%为2e).
结论:
- 2-amido-3-aryl-4-methyl-thiazole衍生物,特别是2e和2f,是PI4KIIIβ的有效抑制剂.
- 化合物2e (KR-27452) 显示出显著的前景,作为开发新型,广泛的抗病毒药物的主要候选人,用于对抗犀牛病毒.
- 已识别的化合物向宿主因子,这表明对相关病毒具有广泛的活性.
