pharmacokinetic (PK) properties of GLS4, herein, we retained the dominant fragments, and used a scaffold hopping strategy to replace the easily metabolized morpholine ring of GLS4 with diverse sizes of spiro rings consisting of hydrogen bond donor and acceptor substituents. Potent in vitro anti-HBV activity and low cytotoxicity were observed for compound 4r (EC50 = 0.20 ± 0.00 μM, CC50 > 87.03 μM), which
GLS4是一种强效抗病毒候选药物,已被广泛研究并进入II期临床试验。然而,GLS4的治疗应用由于水溶性差、半衰期短和生物利用度低而受到限制。为了提高GLS4的亲水性和药代动力学(PK)特性,本文中,我们保留了主要片段,并使用支架跳跃策略将GLS4易于代谢的吗啉环替换为不同尺寸的由氢键供体和氢键供体组成的螺环受体取代基。观察到化合物4r具有有效的体外 抗HBV 活性和低细胞毒性(EC 50 = 0.20 ± 0.00 μM,CC 50 > 87.03 μM),其比阳性对照拉米夫定(EC 50 = 0.37 ± 0.04 μM,CC )更有效。 50 > 100.00 μM),其有效性约为 GLS4 的四分之一(EC 50 = 0.045 ± 0.01 μM,CC 50 > 99.20 μM)。进行了初步构效关系(SAR)分析和分子对接研究,以探索化合物与靶蛋白之间潜在的相互作用和
