Abstract A series of benzo[b]thiophen-3-ols were synthesised and investigated as potential human monoamine oxidase (hMAO) inhibitors in vitro as well as ex vivo in rat cortex synaptosomes by means of evaluation of 3,4-dihydroxyphenylacetic acid/dopamine (DOPAC/DA) ratio and lactate dehydrogenase (LDH) activity. Most of these compounds possessed high selectivity for the MAO-B isoform and a discrete
抽象的 合成了一系列苯并[ b ]噻吩-3-醇,并在体外和离体中作为潜在的人单胺氧化酶(hMAO)抑制剂进行了研究通过评估3,4-二羟基苯基乙酸/多巴胺(DOPAC / DA)的比例和乳酸脱氢酶(LDH)活性来评估大鼠皮层突触小体中的脂质。这些化合物大多数对MAO-B同工型具有高选择性,并具有离散的抗氧化剂和螯合电位。所有化合物的分子对接研究强调了适合MAO抑制活性的潜在结合位点相互作用,并提出了通过化学修饰芳基取代基进一步改善该支架活性的结构要求。从这个杂环核开始,可以开发出用于治疗神经退行性疾病的新型先导化合物。

Abstract A facilesynthesis of 2-substituted benzo[b]thiophen-3-ols in a simple reaction system is reported with water as the only media. Density functional theory (DFT) investigations suggest two pathways comparable in energetics: A neutral pathway with concerted C-C bond formation and hydrogen transfer and an anionic pathway with anion attack to the carbonyl group. Studies indicate that water plays

Iron—the mediator: 1,3‐Diketone ligands coordinated to iron undergo unprecedented tandemreactions with 2‐thiosalicylic acids to give 2‐substituted 3‐hydroxylbenzo[b]thiophenes in up to 98 % yield. A similar reaction with 2‐mercaptonicotinic acid gave a thieno[2,3‐b]pyridine derivative in 72 % yield (see scheme). A mechanism involving redox transformation and tandemradicalcyclization of the coordinated
