Approved drug
heparin is an approved drug (FDA (1939))
Comment: Heparin is an endogenous secretory glycosaminoglycan (GAG) that is released predominantly from connective tissue mast cells. Isolated heparin is used clinically as an anti-coagulant. Structurally, heparins (generally known as unfractionated heparin) are a heterogeneous group of anionic, sulfated GAGs. Commercial preparations usually vary in size from 12-15 kDa, while a low molecular weight (fractionated) versions are also available. Database entries may specify the sodium salt forms.

SARS-CoV-2: There is strong experimental evidence which shows that heparin interacts directly with GAG-binding motifs on the Spike glycoprotein of SARS-CoV-2 [3], and that inhibiting this interaction can reduce SARS-CoV-2 infection of host cells [6,8]. These findings suggest that heparin may offer repurposing potential as a prophylactic COVID-19 therapeutic [2], in addition to its benefit as a treatment for COVID-19-related thrombotic complications.
