GtoPdb Ligand ID: 11602

Synonyms: DX-600
Comment: DX600 is a peptide inhibitor of angiotensin-converting enzyme 2 (ACE2) [1]. It blocks the cardioprotective effect of ACE2, but does not inhibit ACE activity [1-2].
A gallium-68 labeled cyclic DX600 derivative can be used as an ACE2 radiotracer [3]

SARS-CoV-2 and COVID-19: Experiments using lab-grown, human embryonic stem cell-derived beating cardiomyocytes have demonstrated that DX600 can prevent pseudotyped SARS-CoV-2 from entering the heart cells [4]. This research indicates that agents that physically block spike-ACE2 binding could be leveraged as novel infection preventatives, that also offer the potential to reduce SARS-CoV-2-mediated damage to heart tissue.
