overcome this limitation, we report a solid-phase approach to Ahp cyclodepsipeptides that is based on the use of a maskedglutamic aldehyde moiety as a general Ahp precursor molecule. As a proof-of-concept, we therefore recently reported the solid-phase synthesis of Symplocamide A. Here, we want to give a full account on the development and application of the masked glutamic aldehyde moiety as well as
含有环缩肽的 3-氨基-6-羟基-2-哌啶酮 (Ahp) 是一类有趣的天然产物,它以可逆、非共价的方式抑制 S1(胰蛋白酶和糜蛋白酶样)丝氨酸蛋白酶,将它们变成潜在的化学工具,用于蛋白酶研究。然而,它们在化学生物学中的系统应用受到它们繁琐的液相化学合成的阻碍。为了克服这一限制,我们报告了一种 Ahp 环缩肽的固相方法,该方法基于使用掩蔽谷氨酸部分作为一般 Ahp 前体分子。因此,作为概念验证,我们最近报道了 Symplocamide A 的固相合成。在这里,我们想全面介绍掩蔽谷氨酸部分的开发和应用以及固相的优化。相合成,
