A facile, convenient and high yielding synthesis of novel S-glycosides and N-glycosides incorporating 1,2,3,4-tetrahydronaphthalene and or 1,2-dihydropyridines moieties has been described. The aglycons 2, 4, and 7 were coupled with different activated halosugars in the presence of basic and acidic medium. The preliminary in-vitro cytotoxic evaluation revealed that compounds 3c, 3f, 5c and 7b show promising activity. A molecular docking study was performed against tyrosine kinase (TK) (PDB code: 1t46) by Autodock Vina. The docking output was analyzed and some compounds have shown hydrogen bond (H-B) formation with reasonable distances ranged from 2.06 A° to 3.06 A° with Thr 670 and Cys 673 residues found in the specified pocket. No hydrogen bond was observed with either Glu 640 nor Asp 810 residues, as was expected from pdbsum.
已经描述了掺入1,2,3,4-四氢萘和/或1,2-二氢吡啶部分的新型S-糖苷和N-糖苷的简便且高产率的合成。在碱性和酸性介质存在下,苷元 2、4 和 7 与不同的活化卤糖偶联。初步体外细胞毒性评估表明,化合物 3c、3f、5c 和 7b 显示出良好的活性。 Autodock Vina 针对酪氨酸激酶 (TK)(PDB 代码:1t46)进行了分子对接研究。对对接输出进行了分析,一些化合物显示出氢键 (H-B) 形成,合理距离范围为 2.06 A° 至 3.06 A°,在指定口袋中发现了 Thr 670 和 Cys 673 残基。正如 pdbsum 所预期的那样,Glu 640 和 Asp 810 残基均未观察到氢键。
