interesting starting point for the development of a new suite of linker drugs for antibody drug conjugates (ADCs). Structure activity relationships were explored on the small molecule which led to six linker drugs being developed for conjugation to antibodies. Herein we describe the synthesis of novel PNU-159682 derivatives and the subsequent linker drugs as well as the corresponding biological evaluations
PNU-159682是新霉素的高效次级代谢产物,属于天然蒽环类药物。由于其极高的效力和仅部分了解的作用机理,因此被认为是开发用于抗体药物偶联物(ADC)的新的连接剂套件的有趣起点。在小分子上探索了结构活性关系,这导致开发出六种用于与抗体缀合的接头药物。在这里,我们描述了新型PNU-159682衍生物的合成以及随后的接头药物以及小分子和ADC的相应生物学评估。
