represent the synthesis and study of a previously unexplored heterocycle. This new class of activated cyclic carbamates provided selective irreversible inhibition of a small subset of serine hydrolases without release of a leaving group, does not covalently modify active site catalytic cysteine and lysine residues of other enzyme classes, and was found to be amenable to predictable structural modifications
公开了作为候选丝氨酸水解酶抑制剂的 4,1,2-苯并氧噻嗪-3-酮 1,1-二氧化物的设计和检验,并且代表了先前未探索的杂环的合成和研究。这种新型的活化环状氨基甲酸酯对一小部分丝氨酸水解酶提供选择性不可逆抑制,而不释放离去基团,不会共价修饰其他酶类的活性位点催化半胱氨酸和赖氨酸残基,并且被发现适合可预测的结构调节内在反应性或活性位点识别的修饰。更值得注意的是,在初步研究中检查的候选抑制剂的小规模试点系列中,发现了一种对参与脂肪细胞甘油三酯稳态的丝氨酸水解酶(PNPLA4,含patatin样磷脂酶结构域的蛋白4)的精细选择性抑制剂。
