To elucidate the structure-activity relationship of 17 matrine alkaloids from Bunge, their effect on hepatitis B surface antigen (HBsAg) secretion was studied using the MTT assay. A 3D-QSAR analysis showed a strong correlation between chemical structures and biological activities ( = 0.625, = 0.859). Molecular docking and molecular dynamics simulations revealed that hydrogen bonding and hydrophobic interactions with hepatitis B core protein (PDB:5T2P) are key to inhibiting HBsAg secretion, suggesting potential for developing natural anti-hepatitis B drugs.
为阐明来自苦参的17种苦参生物碱的构效关系，采用MTT法研究了它们对乙型肝炎表面抗原（HBsAg）分泌的影响。三维定量构效关系（3D-QSAR）分析表明化学结构与生物活性之间存在强相关性（r = 0.625，q = 0.859）。分子对接和分子动力学模拟显示，与乙型肝炎核心蛋白（PDB:5T2P）的氢键和疏水相互作用是抑制HBsAg分泌的关键，这表明开发天然抗乙型肝炎药物具有潜力。
