Protein-Protein Interactions (PPIs) play a very important role in biological functions and therefore the inhibition of specific Protein-Protein Interactions has a huge therapeutic value. The most successful small molecular PPIs inhibitors do not fit with the prevalent `Rule of Five' drug profile. To overcome the disadvantages of small molecular PPIs inhibitors, peptide based PPIs inhibitors were developed. Herein we describe the development of a new class of peptidomimetics AA-peptides. The AApeptides were designed based on chiral PNA backbone. Substitution of nucleobases yields AApeptides that are resistant to proteolysis and capable of mimicking peptides. Two types of AApeptides were discussed in …
