The enantioselective binding of the (SSS)-Δ isomer of an yttrium(III) tetraazatriphenylene complex to ‘drug-site II’ of human serum albumin (HSA) was detected by the intensity differences of its STD 1H NMR spectrum relative to the (RRR)-Λ isomer, by the effect of the competitive binder to that site, N-dansyl sarcosine, upon the STD spectrum of each isomer, in the presence of HSA and by 3D docking simulations.
通过其 STD 1H NMR 光谱相对于 (RRR)-Λ 异构体的强度差异,检测了
钇(III) 四氮杂三苯骈合物的 (

SA 存在的情况下,通过该位点的竞争性粘合剂 N-丹酰
肌氨酸对每种异构体 STD 光谱的影响,并通过三维对接模拟进行检测。
