[Reuters] that they evaluated the antiviral efficiency of seven drugs in vitro. Chloroquine, a widely used anti-malaria and autoimmune disease drug, has been known to block virus infections by changing the acidity and basicity value inside the cell and interfering with receptors of SARS coronavirus. Define chloroquine Who can do plaquenil test Chloroquine CQ is a lysosomotropic agent with an extensive range of biological effects 1. Historically known for its anti-malarial activity, chloroquine is a widely used biological research tool for studying autophagy inhibition. Research studies demonstrate that chloroquine accumulates in acidic lysosomes and increases the lysosomal pH. Chloroquine-treated ARPE-19 cells demonstrate a marked increase in vacuolation and dense intracellular debris. This might explain the more intense lysotracker signaling. Cancer cells are thought to use autophagy as a source of energy in the unfavorable metastatic environment, and a number of clinical trials are now revealing the promising role of chloroquine, an autophagy inhibitor, as a novel antitumor drug. On the other hand, however, the kidneys are highly vulnerable to chemotherapeutic agents. Vero E6 cells, derived from the kidney of an African green monkey, are one of the commonly used mammalian cell lines in microbiology and molecular and cell biology research. In the latest study, chloroquine shows an antiviral effect at both the entry and post-entry stages of the novel coronavirus infection in Vero E6 cells.

Anti-malaria drug prevents coronavirus infection The Standard. Previous studies of chloroquine have demonstrated that it has multiple effects on mammalian cells in addition to the elevation of endosomal pH, including the prevention of terminal glycosyaltion of immunoglobulins. Chloroquine Inhibits Cyclization of Squalene Oxide to Lanosterol in Mammalian Cells* Received for publication, June 29,1983 Harry W. Chen and Deborah A. Leonard+ From The Jackson Laboratory, BUF Harbor, Maine 04609 Chloroquine inhibits the incorporation of ‘“Cace- Preinfection chloroquine treatment renders Vero E6 cells refractory to SARS-CoV infection. In order to investigate if chloroquine might prevent SARS-CoV infection, permissive Vero E6 cells were pretreated with various concentrations of chloroquine 0.1–10 μM for 20–24 h prior to virus infection. Cells were then infected with SARS-CoV, and virus antigens were visualized by indirect immunofluorescence as described in Materials and Methods.
