    MAG拮抗剂的动力学和热力学性质。
    摘要:
    截瘫是由中枢神经系统(CNS)受伤引起的,尤其是年轻人遭受这些严重后果的困扰,例如,运动功能丧失。受损神经链修复的缺乏源于中枢神经系统中轴突再生的抑制环境。特定的抑制蛋白可阻止神经根的再生。这些神经突生长抑制剂之一是髓磷脂相关糖蛋白(MAG),它是Siglec家族的成员(唾液酸结合免疫球蛋白样凝集素)。在以前的研究中,我们确定了有效的小分子MAG拮抗剂。在此通报中,我们报告了在4位和5位修饰的新神经氨酸衍生物,以及各种结构修饰对其动力学和热力学结合性质的影响。

    Low Molecular Weight Antagonists of the Myelin-Associated Glycoprotein: Synthesis, Docking, and Biological Evaluation
    摘要:
    The Injured adult mammalian central nervous system Is all inhibitory environment for axon regeneration due to specific inhibitors,among them the myelin-associated glycoprotein (MAG), a member of the Siglec family (sialic-acid binding immunoglobulin-like lectin). In earlier Studies, we identified the lead structure5, which shows a 250-fold improved in vitro affinity for MAG compared to the tetrasaccharide binding epitope of GQ1b alpha (1), the best physiological MAG ligand described so far. By modifying the 2- and 5-position, the affinity of 5 could be further improved to the nanomolar range (-> 19a). Docking Studies to a homology model of MAG allowed the rationalization of the experimental binding properties. Finally, pharmacokinetic parameters (stability in the cerebrospinal fluid, logD and Permeation through the BBB) indicate the drug-like properties of the high-affinity antagonist 19a.
