Next, triblock ABA and ABC copolymers including both ECD and QCD ligands had been synthesized with 96 monomer spacers mainly because their B blocks. Although these polymers got lower densities of QCD and ECD peptides, their potencies correlated with the potencies of their related homopolymers. Furthermore, no synergy between ECD and QCD mimics was noticed.
