    Chloroquine glycosylation


    Despite drastic containment measures, the spread of this virus is ongoing. SARS-Co V-2 is the aetiological agent of coronavirus disease 2019 (COVID-19) characterised by pulmonary infection in humans.

    As discussed above, glycosylation inhibition might represent a major mechanism for the antiviral effects of chloroquine, suggesting that specific interactions of chloroquine with sugar-modifying enzymes or glycosyltransferases may occur within human cells. Chloroquine was recently shown to inhibit quinone reductase 2, In vitro studies of SARS-Cov-1 infection in a primate cell line showed that CQ was an effective pre- and post-infective antiviral agent. 9 Specifically, CQ-induced altered ACE2 glycosylation was felt to be the mechanism by which pretreatment prevented infection by inhibiting S-protein binding and subsquent phagocytosis, and CQ-induced. Chloroquine, a widely-used anti. as well as interfering with the glycosylation of cellular receptors of SARS-CoV. 10 Our time-of-addition assay demonstrated that chloroquine functioned at both.

    In the absence of a known efficient therapy and because of the situation of a public-health emergency, it made sense to investigate the possible effect of chloroquine/hydroxychloroquine against SARS-Co V-2 since this molecule was previously described as a potent inhibitor of most coronaviruses, including SARS-Co V-1. The efforts of international health authorities have since focused on rapid diagnosis and isolation of patients as well as the search for therapies able to counter the most severe effects of the disease.

  6. It possesses in vitro antiviral activities against SARS-CoV and HCoV-229E, and the anti-inflammatory properties of chloroquine have been postulated to be beneficial for the treatment of SARS. 35 The mechanism of action of chloroquine is unknown, but may involve alterations of ACE2 glycosylation and endosomal pH.

    The anti-viral and anti-inflammatory activities of chloroquine may account for its potent efficacy in treating patients with COVID-19 pneumonia. Chloroquine is a very cheap and safe drug that has been used for decades to treat is efficacious as an anti-inflammatory agent for the treatment of rheumatoid arthritis and lupus erythematosus. Hydroxychloroquine and chloroquine have been recommended by Chinese and South Korean health authorities for the experimental treatment COVID-19. In vitro studies in cell cultures demonstrated that hydroxychloroquine was more potent than chloroquine against SARS-CoV-2. Infectivity viruses. This inhibited glycosylation will there-fore allow time for the adaptive immune response to deal with the infection Baize et al. 1999. Immunomodulatory Property of Chloroquine Analogs The anti-inflammatory and immunomodulatory actions of chloroquine analogs have also been beneficial in the
