"CQ / HCQ also blocks the endocytosis of SARS-CoV-2 by suppressing the phosphatidylinositol binding clathrin assembly protein."

reach
"Previous studies also demonstrate that chloroquine and hydroxychloroquine elevate the pH of endosomes in the cells and directly inhibit endocytosis and the exocytic process (Munro et al, 1997; Devaux et al, 2020)."

"In vitro analyses have indicated that hydroxychloroquine and chloroquine can prevent viral endocytosis [1]."

"Some drugs from the primary investigations that are used for COVID-19 are protease inhibitor lopinavir / ritonavir , nucleoside analogs , neuraminidase inhibitors , remdesivir , umifenovir ( arbidol ) , tenofovir disoproxil ( TDF ) , lamivudine ( 3TC ) and hydroxychloroquine , which blocks virus entry and endocytosis ( Lu , 2020 ) ( Figure 1 ) ."

"Moreover, Chloroquine and Hydroxychloroquine prevent viral entry and endocytosis, and also play the role of potential immunomodulatory agents.The immune system components react to SARS-CoV-2 mainly related to the inter-individual variation in COVID-19 severity, whereas genes linked with the binding affinity to the ACE2 cell receptor and the viral entry at the early stages of infection, considerably determine thevariable COVID-19 severity and different susceptibility to SARS-CoV-2 infection."

"Concerning the molecular mechanism for their known antiviral activity, chloroquine or hydroxychloroquine was previously proposed to inhibit acidification of endosome and viral endocytosis."
