acid esters of β-lactone derivatives structurally related to tetrahydrolipstatin (THL) and O-3841 were synthesized that inhibit human and murine diacylglycerol lipase (DAGL) activities. New ether lipid reporter compounds were developed for an in vitro assay to efficiently screen inhibitors of 1,2-diacyl-sn-glycerol hydrolysis and related lipase activities using fluorescence resonance energy transfer (FRET)
合成了一系列与四氢脂抑素 (THL) 和 O-3841 结构相关的 β-内酯衍生物的N-甲酰基-α-氨基酸酯,可抑制人和鼠二酰基甘油脂肪酶 (DAGL) 的活性。开发了新的醚脂质报告化合物用于体外测定,以使用荧光共振能量转移 (FRET)有效筛选 1,2-二酰基-sn-甘油水解和相关脂肪酶活性的抑制剂。利用标记的内源性底物 [1″- 14 C]1-stearoyl-2-arachidonoyl- sn - glycerol 进行二酰基甘油脂肪酶活性的标准化薄层色谱 (TLC) 放射分析,并通过磷光成像检测通过以下初始形成来量化抑制产品 [1″-14 C]2-花生四烯酸甘油并在测定条件下进一步水解为[1- 14 C]花生四烯酸。
