Abstract

Hepatitis B virus (HBV) constitutes a significant public health burden, and currently available treatment options are not generally curative, necessitating the development of new therapeutics. Here we have applied random non-standard peptide integrated discovery (RaPID) screening to identify small macrocyclic peptide inhibitors of HBV entry that target the cell-surface receptor for HBV, sodium taurocholate cotransporting polypeptide (NTCP). In addition to their anti-HBV activity, these molecules also inhibit cellular entry by the related hepatitis D virus (HDV), and are active against diverse strains of HBV (including clinically relevant nucleos(t)ide analog-resistant and vaccine escaping strains). Importantly, these macrocyclic peptides, in contrast to other NTCP-binding HBV entry inhibitors, exhibited no inhibition of NTCP-mediated bile acid uptake, making them appealing candidates for therapeutic development.

Keywords: HBV; HDV; NTCP; RaPID; bile acid; cyclosporin; entry; inhibitor; macrocyclic; transporter.
