Glycobiologists with access to any of the compounds mentioned herein or related to glycosylation interdictors are encouraged to send their samples for testing to virology labs conducting SARS COV2/ACE2-binding studies, spike glycoprotein fusion tests, or infectivity assays. Repurposing of already approved drugs, and testing others with low toxicity may uncover other avenues from a solid glycobiology antiviral background for a much-needed development of COVID19 therapeutics. There are also outstanding opportunities for selectin anti-inflammatory and heparinoid anticoagulation approaches for COVID19 ARDS.
