Fragment-based drug discovery relies on successful optimization of weakly binding ligands for affinity and selectivity. Herein, we explored strategies for structure-based evolution of fragments binding to a G protein-coupled receptor. Molecular dynamics simulations combined with rigorous freeenergy calculations guided synthesis of nanomolar ligands with up to >1000-fold improvements of binding affinity
基于片段的药物发现依赖于弱结合配体的亲和力和选择性的成功优化。在此,我们探索了与 G 蛋白偶联受体结合的片段的基于结构的进化策略。分子动力学模拟结合严格的自由能计算指导纳米摩尔配体的合成,结合亲和力提高了 1000 倍以上,亚型选择性接近 40 倍。
Pyrazolo[3,4-<i>d</i>]pyrimidines as sigma-1 receptor ligands for the treatment of pain. Part 1: 4-acylamino derivatives
new series of 4-acylaminopyrazolo[3,4-d]pyrimidines active on the sigma-1 receptor (σ1R) is reported. Compounds were efficiently prepared using a two to three step process starting from commercially available 1H-pyrazolo[3,4-d]pyrimidin-4-amine. A SAR study shows that the σ1R requires the presence of relatively highly lipophilic substituents at opposite sides of the central scaffold, while selectivity

Decomposition-sensitive complex ligands can be stabilized by derivatizing them with the aid of bulky secondary or tertiary carboxylic acids or sulfonic acids. These stabilized derivatives can be added to alignment layers and liquid-crystal mixtures and increase the contrast and brightness in the FLC display.
