monophosphonate as a bone‐affinity tag that confers moderate affinity to bone, which can furthermore be tuned to the desired level, and the relationship between structure and bone affinity was evaluated by using an NMR‐based bone‐binding assay. The concept of targeting drugs to bone with moderate affinity, while retaining oral bioavailability, has broad application to a variety of other bone‐targeted drugs.
将药物靶向其所需的作用部位可以增加其安全性和功效。双膦酸盐是靶向骨骼的药物的典型例子。但是,通常认为双膦酸酯的骨亲和力太强,不能在不失去对酶标靶法呢基焦磷酸合酶(FPPS)的活性的情况下对其进行显着调节。此外,双膦酸酯骨亲和力是以非常低和可变的口服生物利用度为代价的。FPPS抑制剂是用单膦酸盐作为骨亲和标签开发的,赋予了对骨骼适度的亲和力,可以进一步调节至所需水平,并通过基于NMR的骨结合测定法评估了结构与骨亲和性之间的关系。 。以中等亲和力将药物靶向骨骼的概念,同时保留口服生物利用度,
