Abstract
A polyproline nanocage compound includes two cyclic peptide scaffolds and at least three connecting molecules. The two cyclic peptide scaffolds include at least three polyproline helix rods and at least three turn-angle molecules. Each of the at least three polyproline helix rods is composed of a plurality of repeat units. Two of the at least three polyproline helix rods are connected by one of the at least three turn-angle molecules so as to form a closed ring. The at least three connecting molecules are respectively connected from the at least three polyproline helix rods of one of the two cyclic peptide scaffolds to the at least three polyproline helix rods of the other of the two cyclic peptide scaffolds.
