BMC is -64.41 kcal/mol when adsorbed with Ag6, pointing to a chemisorption process. TD-DFT predicts a Ultraviolet (UV)-vis absorption of 595.11 when BMC adsorbed on Ag6, while that of BMC is 276.12 nm and the redshift, lowered intensity in UV spectra, caused by the aggregation of colloidal silver nano particles, was used to establish the adsorption of BMC on Ag6. Molecular docking is performed on BMC
对新型生物活性分子 2-(3-溴苯甲酰基) -N-甲基肼-1-甲酰胺 (BMC)进行了详细的理论和实验研究。密度泛函理论 (DFT)、时间相关 (TD)-DFT 和表面增强拉曼散射 (SERS) 研究报告了 BMC 在银水溶胶上的吸附。讨论了各种浓度下的 SERS,BMC 的取向随浓度发生变化,BMC 与金属呈倾斜取向。BMC吸附Ag 6时的吸附能为-64.41 kcal/mol ,属于化学吸附过程。TD-DFT 预测当 BMC 吸附在 Ag 6上时,紫外 (UV)-vis 吸收为 595.11,而 BMC 的波长为 276.12 nm,红移、紫外光谱强度降低(由胶体银纳米颗粒的聚集引起)用于确定 BMC 在 Ag 6 上的吸附。对 BMC 和 BMC-Ag 6进行分子对接以发现它们与靶蛋白结合的能力,IP0I(人丁酰胆碱酯酶)和 4PQE(人乙酰胆碱酯酶)和药物相似性也进行了评估。BMC-Ag
