different ceramide generating sphingomyelinases are still unclear. Recently, we reported on the synthesis of the first selective irreversible inhibitor of the neutral sphingomyelinase (N-SMase), as well as the identification of Manumycin A and some of its analogues as irreversible inhibitors of N-SMase. For the development of pharmacologically interesting competitive inhibitors of N-SMase, structure-activity
鞘脂神经酰胺被认为是重要的细胞内介体。然而,其作用的许多方面以及几种产生神经酰胺的鞘磷脂酶的作用仍不清楚。最近,我们报道了第一个中性鞘磷脂酶(N-SMase)的选择性不可逆抑制剂的合成,以及将Manumycin A及其某些类似物鉴定为N-SMase的不可逆抑制剂。为了开发N-SMase的药理学上令人感兴趣的竞争性抑制剂,结构活性研究至关重要。本文中,我们显示了两种鞘磷脂抑制素类似物3a和3b的合成和酶促研究,揭示了化合物2中伯羟基对N-SMase抑制的重要性。
