A new series of d-glucose-conjugated 2,3-thiazoline-benzo-[]-thiazole hybrid compounds - were synthesized from reaction of the corresponding thioureas - and ethyl bromoacetate in the presence of sodium acetate in chloroform. The evaluations for anti-Alzheimer activity showed that some compounds exhibited remarkable inhibitory activity against AChE and BChE as well as against MAO-A and MAO-B enzymes. The orders of inhibition for each enzyme of these compounds were as follows: > (against AChE), > (against BChE), > > (against MAO-A), and > (against MAO-B). Compound was an inhibitor of interest due to its potent or good activity against the two studied enzymes BChE and MAO-B, respectively. Compounds (against AChE) and (against (BChE) had a competitive type with constants of 16.93 and 17.09 nM, respectively. The most potential compounds , , and were not cytotoxic on 3T3 cells and had high levels of safety.
一系列新的d-葡萄糖共轭的2,3-噻唑啉-苯并[]-噻唑杂化化合物——由相应的硫脲与溴乙酸乙酯在醋酸钠存在下于氯仿中反应合成。抗阿尔茨海默病活性评估表明，一些化合物对乙酰胆碱酯酶（AChE）、丁酰胆碱酯酶（BChE）以及单胺氧化酶A（MAO-A）和单胺氧化酶B（MAO-B）均表现出显著的抑制活性。这些化合物对每种酶的抑制顺序如下： ＞ （针对AChE）， ＞ （针对BChE）， ＞ ＞ （针对MAO-A），以及 ＞ （针对MAO-B）。化合物 因其分别对所研究的两种酶BChE和MAO-B具有强效或良好活性而成为有意义的抑制剂。化合物 （针对AChE）和 （针对BChE）具有竞争类型，其 常数分别为16.93和17.09 nM。最具潜力的化合物 、 和 对3T3细胞无细胞毒性且具有高安全性。
