There is disclosed an antibody and antibody-drug conjugate for targeting drug delivery as well as a class of chemicals, termed an "antimer." The antimer is designed to "fit" the drug by combining multiple non-covalent interactions between functional groups on the drug and opposing functional groups on the antimer. The net result on the antibody-antimer-drug conjugate is a drug stably bound to the antimer so as not to dissociate during in vivo administration, but not so tightly bound to allow drug dissociation from the conjugate without significant loss of activity and retaining the drug's ability to bind to a higher affinity site on the or within the target cell.
本文公开了一种用于靶向给药的
抗体和
抗体-药物共轭物,以及一类称为 "抗聚物 "的
化学品。抗聚物是通过药物上的官能团与抗聚物上的对立官能团之间的多种非共价相互作用来 "配合 "药物的。
抗体-抗聚物-药物共轭物的最终结果是,药物与抗聚物稳定结合,在体内给药时不会解离,但又不会结合得太紧密,以至于药物从共轭物中解离而不会明显丧失活性,同时还能保持药物与靶细胞上或靶细胞内亲和力较高的位点结合的能力。
