DUBLIN — The little-known drug thapsigargin has proven “highly effective” against Covid-19, according to a University of Nottingham research team, which said the findings are “hugely significant.” The research, published on Wednesday in the journal Viruses, found that the plant-derived antiviral “triggers a highly effective broad-spectrum host-centred antiviral innate immune response against three major types of human respiratory viruses,” including the novel coronavirus that causes Covid-19. Though “more testing is clearly needed,” according to research team leader Professor Kin-Chow Chang, “current findings strongly indicate that thapsigargin and its derivatives are promising antiviral treatments against Covid-19 and influenza virus.” Several treatments for virus-induced disease have been deployed since the first wave of the pandemic, including the steroid dexamethasone and an antibody cocktail developed by the company Regeneron, which was used on former US president Donald Trump when he was hospitalized in October.
