target and involved in rapid lipid signalling events. However, there are no tools available to adequately study such processes. Based on a non cell-permeable PtdIns(3,5)P2 inhibitor of ASM, we developed a compound with o-nitrobenzyl photocages and butyryl esters to transiently mask hydroxyl groups. This resulted in a potent light-inducible photocaged ASM inhibitor (PCAI). The first example of a time-resolved
酸性鞘
磷脂酶(ASM)是潜在的药物靶标,参与快速的脂质信号传递事件。但是,没有可用的工具来充分研究此类过程。基于ASM的非细胞渗透性PtdIns(3,5)P 2
抑制剂,我们开发了一种具有邻硝基苄基光笼和
丁酸酯的化合物,可瞬时掩盖羟基。这导致了强效的光诱导光笼ASM
抑制剂(PCAI)。在完整的活细胞中显示了时间分辨抑制ASM的第一个例子。
