Total chemical synthesis of human interferon alpha-2b via native chemical ligation.

ABSTRACT: Interferon-alpha (IFNα) is a cytokine that orchestrates innate and adaptive immune responses and potently inhibits proliferation of normal and tumor cells. These properties have warranted the use of IFNα in clinical practice for the treatment of several viral infections and malignancies. However, overexpression of IFNα leads to immunopathology observed in the context of chronic viral infections and autoimmune conditions. Thus, it is desirable to develop therapeutic approaches that aim at suppressing excessive IFNα production. To that end, artificial evolution of peptides from phage display libraries represents a strategy that seeks to disrupt the interaction between IFNα and its cell surface receptor and thus inhibit the ensuing biological effects.
