  纳米药理学力传感揭示转运蛋白结合位点的变构耦合

  摘要：

  关于神经递质/钠同向转运体中配体结合位点的数量和功能的争议源于晶体结构和分子药理学中相互矛盾的数据。在这里，我们设计了新的原子力显微镜工具，可以在单分子水平上直接测量血清素转运蛋白 (SERT) 与西酞普兰的S和R对映体之间的相互作用力。这种方法基于力谱，它允许在生理条件下提取动态信息，因此无法通过 X 射线晶体学获得。在含 Na +的缓冲液中揭示了西酞普兰与 SERT 的两个不同群体的特征结合强度。相反，在 Li +含有缓冲液的 SERT 仅显示低力相互作用。相反，前庭突变体 SERT-G402H 仅显示高力群体。这些观察结果为在生理环境中访问时 SERT 中存在两个结合位点提供了物理证据。竞争实验表明，这两个位点变构耦合并施加相互调制。

  Novel and High Affinity Fluorescent Ligands for the Serotonin Transporter Based on (S)-Citalopram

  摘要：

  Novel rhodamine-labeled ligands, based on (S)citalopram, were synthesized and evaluated for uptake inhibition at the human serotonin, dopamine, and norepinephrine transporters (hSERT, hDAT, and hNET, respectively) and for binding at SERT, in transiently transfected COS7 cells. Compound 14 demonstrated high affinity binding and selectivity for SERT (K-i; = 3 nM). Visualization of SERT, using confocal laser scanning microscopy, validated compound 14 as a novel tool for studying SERT expression and distribution in living cells.

  Three photoaffinity ligands (PALs) for the human serotonin transporter (hSERT) were synthesized based on the selective serotonin reuptake inhibitor (SSRI), (S)-citalopram (1). The classic 4-azido-3-iodo-phenyl group was appended to either the C-1 Or C-5 position of the parent molecule, with variable-length linkers, to generate ligands 15, 22, and 26: These ligands retained high to moderate affinity binding (K-i = 24-227 nM) for hSERT, as assessed by [H-3]5-HT transport inhibition. When tested against Ser438Thr hSERT, all three PALs showed dramatic rightward shifts in inhibitory potency, with K-i values ranging from 3.8 to 9.9 mu M, consistent with the role of Ser438 as a key residue for high-affinity binding of many SSRIs, including (S)-citalopram. Photoactivation studies demonstrated irreversible adduction to hSERT by all ligands, but the reduced (S)-citalopram inhibition of labeling by [I-125]15 compared to that by [I-125]22 and [I-125]26 suggests differences in binding mode(s). These radioligands will be useful for characterizing the drug protein binding interactions for (S)-citalopram at hSERT.
