    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.

    Abnormal glycosylation and altered Golgi structure in colorectal cancer dependence on intra-Golgi pH Sakari Kellokumpua;, Raija Sormunenb, Ilmo Kellokumpuc aDepartment of Biochemistry, University of Oulu, P. O. Box 3000, FIN-90014 Oulu, Finland In addition to the well-known functions of chloroquine such as elevations of endosomal pH, the drug appears to interfere with terminal glycosylation of the cellular receptor, angiotensin-converting enzyme 2. 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.

    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.

  4. 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,

    Chloroquine Professional Patient Advice - Oct 04, 2019 Chloroquine resistance is widespread in P. falciparum and is reported in P. vivax. Prior to initiation of chloroquine for prophylaxis, it should be determined if chloroquine is appropriate for use in the region to be visited; do not use for malaria prophylaxis in areas where chloroquine resistance occurs.

    Flecainide Acetate flecainide acetate dose, indications. Ventricular arrhythmias and torsade de pointes TdP have been reported with the use of hydroxychloroquine. Flecainide is a Class IC antiarrhythmic associated with a possible risk for QT prolongation and/or TdP; flecainide increases the QT interval, but largely due to prolongation of the QRS interval.
