state by IR for all complexes and for 1 by X-ray single crystal analysis. The NMR study has shown a decrease in the coordination number of tin in solution. The complexes were screened for their in vitro antibacterial and antifungal activities. A compromised lipo/hydrophilicity and a diffusion controlled antimicrobial activity was shown by the complexes in the order 1 > 2>3 > 4. Molecular docking studies
摘要 四种新的二有机锡 (IV) 羧酸盐 [n-Bu2SnL2] (1)、[Et2SnL2] (2)、[Me2SnL2] (3) 和 [n-Oct2SnL2] (4),其中 L = 3-(4-氯苯基)-2-甲基丙烯酸酯,合成并通过元素分析、FT-IR、多核 NMR(1H、13C 和 119Sn)和 X 射线单晶分析表征 1。一个螯合双齿配体和六配位锡中心得到证实对于所有配合物,IR 为固态,X 射线单晶分析为 1。NMR 研究表明溶液中锡的配位数减少。筛选复合物的体外抗菌和抗真菌活性。复合物按 1 > 2 > 3 > 4 的顺序显示了受损的脂质/亲水性和扩散控制的抗菌活性。分子对接研究表明 1 与抗菌菌株的靶蛋白存在氢键和疏水相互作用。图形概要
