There is disclosed a compound, a pharmaceutical composition and a method of treatment using a pharmaceutical composition comprising a tethering moiety that is capable of binding to a macrophage migration inhibitory factor (MIF) polypeptide, optionally linked to a linker moiety and further covalently bound to a drug moiety or imaging agent. More specifically, there is disclosed a genus of affinity-tethering moieties covalently bound to a drug moiety or imaging agent either directly or optionally via a linker moiety to covalently link the tethering moiety to a drug moiety. Without being bound by theory, the disclosed pharmaceutical compounds are targeted to cancer cells or immune cells via an affinity-tethering moiety that hitch-hikes to or into its target cell while bound to endogenous MIF.
本发明涉及一种化合物、一种药物组合物和使用药物组合物的治疗方法,其中药物组合物包括一种可结合到巨噬细胞迁移抑制因子(MIF)多肽的系留基,可选地与连接基团连接,并进一步共价结合到药物基团或成像剂上。更具体地,本发明涉及一类亲和系留基,它们与药物基团或成像剂直接或可选地通过连接基团共价结合,以共价连接系留基和药物基团。本发明所披露的药物化合物通过亲和系留基定向靶向癌细胞或免疫细胞,系留基通过与内源性MIF结合,搭便车到达或进入其靶细胞。
