Two new anthracene Schiff base triorganotin (IV) compounds trimethylstannyl(E)‐4‐((anthracen‐9‐ylmethylene)amino)benzoate (1) and triphenylstannyl(E)‐4‐((anthracen‐9‐ylmethylene)amino)benzoate (2) were synthesized by mixing trimethylstannyl (or triphenylstannyl) 4‐aminobenzoate and 9‐anthraldehyde in anhydrous toluene under refluxing conditions. Elemental analysis, FT‐IR, 1H‐NMR, 119Sn NMR and ESI‐MS were used to determine the composition of the compounds. X‐ray diffraction analyses revealed the structural details of the compounds. The in vitro cytotoxicity assessment of these compunds was screened against human A‐549 (lung carcinoma) and rat RBL (leukemia) cancer cell lines. Both compounds displayed a pronounced in vitro cytotoxic effect on the subjected cancer cell lines. Notably, the proliferation of A‐549 cells experienced substantial inhibition in the presence of compound 2. The mode of interaction with Hsp90 and NF‐κB p65 proteins responsible for cancer propagation was also assessed by molecular docking. Compounds 1 and 2 bind to the Hsp90 protein with binding energies of −307.65 and −373.45 kcal/mol, respectively, while to NF‐κB p65 protein the binding energies are of −329.35 and −395.35 kcal/mol, in the same order. Compound 2 exhibited a significantly high binding affinity to NF‐κB p65 and Hsp90 proteins validating our experimental findings from the in vitro experiments.
在回流条件下,将 4-氨基苯甲酸三甲基锡(或三苯基锡)和 9-蒽醛在无水甲苯中混合,合成了两种新的蒽希夫基三有机锡(IV)化合物三甲基锡(E)-4-((蒽-9-亚甲基)氨基)苯甲酸酯(1)和三苯基锡(E)-4-((蒽-9-亚甲基)氨基)苯甲酸酯(2)。元素分析、傅立叶变换红外光谱、1H-NMR、119Sn NMR 和 ESI-MS 被用来确定化合物的组成。X 射线衍射分析揭示了化合物的结构细节。针对人 A-549(肺癌)和大鼠 RBL(白血病)癌细胞系对这些化合物进行了体外细胞毒性评估。这两种化合物都对受试癌细胞株产生了明显的体外细胞毒性作用。值得注意的是,在化合物 2 的存在下,A-549 细胞的增殖受到了极大的抑制。此外,还通过分子对接评估了化合物 1 和 2 与 Hsp90 和 NF-κB p65 蛋白的相互作用模式。化合物 1 和 2 与 Hsp90 蛋白的结合能分别为 -307.65 和 -373.45 kcal/mol,而与 NF-κB p65 蛋白的结合能依次为 -329.35 和 -395.35 kcal/mol。化合物 2 与 NF-κB p65 蛋白和 Hsp90 蛋白的结合亲和力非常高,这验证了我们在体外实验中的发现。
