Six organophosphorus compounds linked to fluorophore groups were prepared in an effort to selectively modify the active site of acetylcholinesterase and deliver probes to the gorge region. Two compounds that vary by the length of a methylene (CH2) group, pyrene-SO2NH(CH2)nNHC(O)CH2CH2P(O)(OEt)(F) (where n = 2 or 3) were found to be potent, irreversible inhibitors of recombinant mouse AChE (Ki approximately
制备了六个与荧光团相连的有机磷化合物,以选择性地修饰乙酰胆碱酯酶的活性位点并将探针递送至峡谷区域。发现根据亚甲基(CH2)基团的长度而变化的两种化合物pyr-SO2NH(CH2)nNHC(O)CH2CH2P(O)(OEt)(F)(其中n = 2或3)是有效的,不可逆的重组小鼠AChE的抑制剂(Ki约为10(5)M(-1)min(-1))。尺寸排阻色谱法得到荧光标记的胆碱酯酶缀合物。
