In 2019,European Journal of Medicinal Chemistry included an article by Zhu, Zhenzhu; Yang, Tao; Zhang, Lei; Liu, Lulu; Yin, Enmao; Zhang, Changli; Guo, Zijian; Xu, Chen; Wang, Xiaoyong. SDS of cas: 1539-42-0. The article was titled 《Inhibiting Aβ toxicity in Alzheimer’s disease by a pyridine amine derivative》. The information in the text is summarized as follows:
Alzheimer’s disease (AD) is a neurodegenerative disorder with no radical therapy. Aggregation of amyloid β-peptide (Aβ) induced by various factors is associated with pathogenesis of AD. A pyridine amine derivative, 3-bis(pyridin-2-ylmethyl)aminomethyl-5-hydroxybenzyltriphenylphosphoniumbromide(PAT), is synthesized. The inhibition of self- and metal-induced Aβ aggregation by PAT is confirmed by thioflavine T fluorescence, CD spectroscopy, and TEM. Western blot, RT-PCR and fluorescence imaging indicate that PAT can alleviate the Aβ-induced paralysis, reduce the production of ROS, and protect the mitochondrial function in transgenic C. elegans. Genetic analyses indicate that heat shock protein is involved in the alleviation of Aβ toxicity. PAT also inhibits the activity of acetylcholinesterase in C. elegans. Morris water maze test shows that the memory and cognitive ability of APP/PS1 AD model mice are significantly improved by PAT. Both in vitro and in vivo studies demonstrate that PAT is effective in counteracting Aβ toxicity and ameliorating cognitive functions in AD mice, and therefore a potential lead compound of anti-AD drugs. In the part of experimental materials, we found many familiar compounds, such as Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0SDS of cas: 1539-42-0)
Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0) is a secondary amine with two picolyl substituents. As a tridentate ligand this compound provides three nitrogen donors that affords good selectivity for Zn2+ over biologically relevant metals such as Na+, K+, Mg2+ and Ca2+, and leaves coordination sites free for anion binding.
