The use of peptide drugs can partially solve the drug toxicity problem. Peptide design has aroused widespread interest, but the design technology of specific and selective peptide inhibitors for protein targets has not been established yet. The de novo peptide design method was developed to block the activity of disease-related protein targets. No prior training, which is based on known peptides, is necessary. De novo peptide design, also known as the "inverse peptide folding problem", is a computational method for peptide design ab initio, rather than using known peptide structures.
