Butyrylcholinesterase (BChE) has been considered as a potential therapeutic target for Alzheimer’s disease (AD) because of its compensation capacity to hydrolyze acetylcholine (ACh) and its close association with Aβ deposit. Here, we identified S06-1011 (hBChE IC50 = 16 nM) and S06-1031 (hBChE IC50 = 25 nM) as highly effective and selective BChE inhibitors, which were proved to be safe and long-acting
丁酰胆碱酯酶(BChE)因其水解乙酰胆碱(ACh)的补偿能力及其与Aβ沉积的密切关系而被认为是阿尔茨海默病(AD)的潜在治疗靶点。在这里,我们确定了S06-1011 ( h BChE IC 50 = 16 nM) 和S06-1031 ( h BChE IC 50 = 25 nM) 为高效、选择性 BChE 抑制剂,并被证明是安全且长效的。候选化合物在东莨菪碱和 Aβ 1-42肽诱导的认知缺陷模型中表现出神经保护作用和改善认知的能力。最佳候选者S06-1011提高了BChE底物ghrelin的水平,可以起到改善精神情绪食欲的作用。 S06-1011处理组的体重增加显着增加。因此,抑制BChE不仅对痴呆具有保护作用,而且对治疗和护理也有很大作用。

The first examples of nonenzymatic N-oxidation of heteroarenes in the presence of amines are reported. Pyridine, quinoline, and isoquinoline N-oxides are selectively formed in the presence of more reactive aliphatic and alicyclic amines by use of an in situ protonation strategy and an iminium salt organocatalyst. Application to late-stage functionalization that mimics phase 1 metabolism of small-molecule
NPY Y5 receptor and showing functional antagonism in the forskolin-induced cyclic AMP test. Prelimminary studies in order to understand the structure-activityrelationship were undertaken. Selected compounds were further evaluated for in vivo efficacy, affording the lead compound 2-[4-(8-methyl-2-oxo-4H-benzo[d][1,3]oxazin-1-yl)piperidin-1-yl]-N-(9-oxo-9H-fluo ren-3-yl)acetamide 5p, which displayed
Disclosed are novel heterocyclic derivatives, useful for the treatment of various disease states, in particular cardiovascular diseases such as atrial and ventricular arrhythmias, intermittent claudication, Prinzmetal's (variant) angina, stable and unstable angina, exercise induced angina, congestive heart disease, and myocardial infarction. The compounds are also useful in the treatment of diabetes.
