Adnectins™ are novel fibronectin-based proteins containing domains engineered to bind to targets of therapeutic interest. The molecular weights of adnectins are less than conventional monoclonal antibodies but larger than traditional small molecules. Until now, there has been no information on the placental transfer of adnectins. To assess placental permeability to adnectins in pregnant guinea pigs, a radiolabeled adnectin, ATI-1072, bound to polyethylene glycol through a [14C]Maleimide linker, was synthesized from [1,4-14C]Maleic acid. This publication describes the synthesis and analysis of PEG-[14C]Maleimide-adnectin ([14C]ATI-1072). Copyright © 2013 John Wiley & Sons, Ltd.
Adnectins™ 是一种新型的基于纤连蛋白的蛋白质,含有经过工程改造的结构域,可与治疗感兴趣的靶标结合。 Adnectin 的分子量小于传统的单克隆抗体,但大于传统的小分子。迄今为止,尚无有关 Adnectin 胎盘转移的信息。为了评估怀孕豚鼠胎盘对 Adnectin 的渗透性,从 [1,4-14C] 马来酸合成了放射性标记的 Adnectin ATI-1072,通过 [14C] 马来酰亚胺接头与聚乙二醇结合。该出版物描述了 PEG-[14C]马来酰亚胺-adnectin ([14C]ATI-1072) 的合成和分析。版权所有 © 2013 约翰·威利父子有限公司
