在天然和非生物系统中构建离散且结构多样的折叠体序列,主要使用惰性连接与不可逆的有机共价键,用于保持序列的身份。使用不稳定的配位键在热力学控制下形成序列对于合成的简易性和模块化能力来说很有吸引力,但这会带来有关序列保存的问题。这里介绍了一种将钯 (II) 金属离子整合到序列本身中的方法,通过在金属中心使用配体排列的互补配对来保持保真度。这是通过使用不同齿数和/或氢键能力的位点来实现的。以这种方式,离散和有序的金属序列在一步中形成为热力学产物,

Fragmentscreening of a thermostabilized mGlu5 receptor using a high-concentration radioligand binding assay enabled the identification of moderate affinity, high ligand efficiency (LE) pyrimidine hit 5. Subsequent optimization using structure-based drug discoverymethods led to the selection of 25, HTL14242, as an advanced lead compound for further development.
