GtoPdb Ligand ID: 11501

Synonyms: EK1C4
Compound class: Peptide
Comment: This is the lipopeptide version of EK-1 [1]. It has cholesterol fused at the C terminal via a short peptide linker and a flexible polyethylene glycol (PEG) spacer. Like EK-1 it acts as a viral fusion inhibitor that blocks infection by a range of human coronavirus pseudoviruses and live viruses, including SARS-Co-V and SARS-CoV-2. It is significantly more potent than EK-1, and is active in vitro and in vivo.
