A branched flexible linker that incorporates a fluorescent dansyl moiety was synthesized and used to connect two high affinity NDP-α-MSH ligands or two low affinity MSH(4) ligands. The linker was incorporated into the conjugate by solid-phase synthesis. In vitro biological evaluations showed that potency of binding to the human melanocortin 4 receptor was not diminished for linker−ligand combinations
合成了一个分支的柔性接头,其中掺入了荧光丹磺酰基部分,并用于连接两个高亲和力的NDP-α-MSH配体或两个低亲和力的MSH(4)配体。通过固相合成将接头引入到缀合物中。体外生物学评估显示,相对于单独的相应配体,对于接头-配体组合,与人黑皮质素4受体结合的效力并未降低。
