  Novel 1,2,4-Thiadiazole Derivatives as Potent Neuroprotectors: Approach to Creation of Bioavailable Drugs

  摘要：

  Novel 1,2,4-thiadiazole derivatives as potent neuroprotectors were synthesized and identified. Their ability to inhibit the glutamate stimulated Ca uptake was measured. Permeation experiments on the phospholipid membranes were conducted, and the apparent permeability coefficients were obtained. The partition coefficients in n-octanol/buffer (pH 7.4) and n-hexane/buffer (pH 7.4) immiscible phases (as model systems for characterizing gastrointestinal tract membranes and BBB) were determined. A classification of the studied compounds from the standpoint of "permeability-activity" properties was proposed.

  radical-scavenging capacity. Conjugates 5 had higher anti-BChE activity and greater anti-aggregant potential as well relatively lower potency against carboxylesterase than compounds 4. Quantum-mechanical (QM) characterization agreed with NMR data to identify the most stable forms of conjugates for docking studies, which showed that the compounds bind to both CAS and PAS of AChE consistent with mixed reversible

  我们合成了他克林与1,2,4-噻二唑衍生物的共轭物，它们通过两个不同的间隔基戊基氨基丙烯（化合物4）和戊基氨基丙烷（化合物5）连接，作为治疗阿尔茨海默氏病（AD）的潜在药物。结合物有效抑制胆碱酯酶，对丁酰胆碱酯酶（BChE）起主要作用。它们还可以有效地从乙酰胆碱酯酶（AChE）的外围阴离子位点（PAS）置换丙啶，表明它们可以阻断AChE诱导的β-淀粉样蛋白聚集。另外，这些化合物表现出高的自由基清除能力。与化合物4相比，缀合物5具有更高的抗BChE活性和更高的抗聚集潜力，并且相对于羧酸酯酶的效力相对较低。量子力学（QM）表征与NMR数据相符，以鉴定最稳定形式的偶联物，用于对接研究，这表明化合物与AChE的CAS和PAS结合均具有可逆的混合抑制作用。结合物4是更有效的自由基清除剂，与HOMO在烯胺-噻二唑系统中的定位一致。计算研究表明，所有结合物均预期具有良好的肠道吸收能力，而结合物4和5则分
