Cyclophostin, a structurally unique and potent naturally occurring acetyl cholinesterase (AChE) inhibitor, and its unnatural diastereomer were prepared in 6 steps and 15% overall yield from hydroxymethyl butyrolactone. The unnatural diastereomer of cyclophostin was converted into cyclipostin P, a potent naturally occurring hormone sensitive lipase (HSL) inhibitor, using a one pot dealkylation-alkylation process. The inhibition [IC(50)] of human AChE by cyclophostin and its diastereomer are reported, as well as constituent binding (K(I)) and reactivity (k(2)) constants.
环磷酰胺是一种结构独特且强效的天然乙酰胆碱酯酶 (AChE) 抑制剂,其非天然对映异构体可由羟甲基丁内酯经 6 步反应、总收率 15%制备得到。利用一锅脱烷基-烷基化过程,可将环磷酰胺的非天然对映异构体转化为强效的天然激素敏感脂肪酶 (HSL) 抑制剂环磷酰胺 P。本文报道了环磷酰胺及其非天然对映异构体对人乙酰胆碱酯酶的抑制作用 [IC(50)],以及结合常数 (K(I)) 和反应常数 (k(2))。
