monomeric peptide ligands towards the PDZ domains of the protein PSD‐95 (postsynaptic density 95) leads to potent inhibitors of protein–protein interactions with stability in blood plasma. Optimization of the length of the polyethylene glycol linker results in unprecedented affinity for inhibitors of the PDZ1‐2 domain (see picture).
双重论:单体肽配体向蛋白质PSD-95的PDZ域的二聚化(突触后密度95)导致有效的蛋白质与蛋白质相互作用抑制剂,并在血浆中具有稳定性。聚乙二醇接头长度的优化导致对PDZ1-2结构域抑制剂的前所未有的亲和力(见图)。
