Provided are methods of treating or reducing the risk of developing beta-amyloid production, beta-amyloid deposition, beta-amyloid neurotoxicity (including abnormal hyperphosphorylation of tau) and microgliosis associated with cerebral accumulation of Alzheimer's amyloid by administering therapeutically effective amounts of polyhydroquinoline and dihydropyridine compounds which decrease Abeta production in cells. Further provided are methods for diagnosing diseases associated with cerebral accumulation of Alzheimer's amyloid in animals or humans by administering diagnostically effective amounts of polyhydroquinoline and dihydropyridine compounds which decrease Abeta production in cells.
One-Pot Green Synthesis of Thiazolo[3,2-<i>a</i>]pyridine Derivatives via Tandem Cyclization in Aqueous Media
three‐component domino reactions of readily available thioglycolic acid/ethyl thioglycolate, aromatic aldehydes, and malononitrile/ethyl cyanoacetate in aqueous potassium carbonate at room temperature afforded thiazolo[3,2‐a]pyridinederivatives chemoselectively in good to excellent yield. All the formed 4H‐chromenes were characterized by spectral and X‐ray methods.
易得的巯基乙酸/巯基乙醇酸乙酯,芳族醛和丙二腈/氰基乙酸乙酯在室温下于碳酸钾水溶液中进行容易的三组分多米诺反应,可高选择性地以良好的化学收率获得噻唑并[3,2- a ]吡啶衍生物。所有形成的4 H-色烯均通过光谱和X射线方法表征。
