The present disclosure relates to quinolin-4-one and 4(1H)-cinnolinone compounds and methods of using them to induce self-renewal of stem/progenitor supporting cells, including inducing the stem/progenitor cells to proliferate while maintaining, in the daughter cells, the capacity to differentiate into tissue cells.
Pseudo-irreversible butyrylcholinesterase inhibitors: Structure–activity relationships, computational and crystallographic study of the N-dialkyl O-arylcarbamate warhead
Alongside reversible butyrylcholinesterase inhibitors, a plethora of covalent butyrylcholinesterase inhibitors have been reported in the literature, typically pseudo-irreversible carbamates. For these latter, however, most cases lack full confirmation of their covalent mode of action. Additionally, the available reports regarding the structure–activity relationships of the O-arylcarbamate warhead are
除了可逆丁酰胆碱酯酶抑制剂外,文献中还报道了过多的共价丁酰胆碱酯酶抑制剂,通常是假不可逆氨基甲酸酯。然而,对于后者,大多数情况下缺乏对其共价作用方式的充分确认。此外,关于O-芳基氨基甲酸酯弹头的构效关系的现有报告并不完整。因此,本研究提出了一系列伪不可逆共价氨基甲酸酯人丁酰胆碱酯酶抑制剂的后续研究以及N-二烷基O-芳基氨基甲酸酯弹头的构效关系。通过 IC 50测试结合的共价机制时间依赖性曲线,并通过动力学分析、全蛋白 LC-MS 和晶体学分析依次和越来越多地证实。计算研究提供了对空间限制的宝贵见解,并确定了有问题的、笨重的氨基甲酸酯弹头,这些弹头无法到达催化 Ser198 并对其进行氨基甲酰化。量子力学计算提供了进一步的证据,表明空间效应似乎是决定这些氨基甲酸酯胆碱酯酶抑制剂的共价结合行为及其作用持续时间的关键因素。此外,将可点击的末端炔烃部分引入氨基甲酸酯N -取代基之一并原位用含叠氮化
