WP-1122(WP 1122) is a candidate drug to treat SARS-COV-2(COVID-19) .2-DG completely prevented SARS-CoV–2 replication in Caco–2 cells. Glycolysis is a process by which cells convert glucose into energy and infected (host) cells are induced by viruses to dramatically increase their dependence on glycolysis. WP1122 is a prodrug of 2-DG whereby chemical elements are added to 2-DG to improve its delivery in vivo.

S enantiomer of Hydroxychloroquine. Hydroxychloroquine is a potent drug for the COVID-19 trement.

R enantiomer of Hydroxychloroquine. Hydroxychloroquine is a potent drug for the COVID-19 trement.

AT-511, the free base form of AT-527, against several coronaviruses, including SARS-CoV-2, the causative agent of COVID-19. In normal human airway epithelial (HAE) cell preparations, the average concentration of AT-511 required to inhibit replication of S

AT-527(Bemnifosbuvir hemisulfate), a hemisulfate salt of AT-511, a guanosine nucleotide prodrug, is a potent and orally active HCV viral replication inhibitor. AT-527 is highly effective in the control of SARS-CoV-2 (COVID-19) infection in vitro (EC90=0.47 μM). Bemnifosbuvir hemisulfate has pangenotypic antiviral activity[1][2][3].Bemnifosbuvir hemisulfate has pan-genotypic antiviral activities that inhibits HCV genotype 1a (HCV GT1a), HCV GT1b, HCV GT2a, HCV GT3a, HCV GT4a, and HCV GT5a replication with EC50 values of 12.8 nM, 12.5 nM, 9.2 nM, 10.3 nM, 14.7 nM, and 28.5 nM, respectively[1]. In normal human airway epithelial cells, the concentration of Bemnifosbuvir hemisulfate required to inhibit replication of SARS-CoV-2 by EC90 is 0.47 μM, very similar to its EC90 against HCoV-229E, HCoV-OC43 and SARS-CoV in Huh-7 cells[2].When given orally to rats (500 mg/kg) and monkeys (30 mg/kg, 100 mg/kg or 300 mg/kg), Bemnifosbuvir hemisulfate preferentially delivers high levels of AT-9010 in the liver in vivo[1].

FOY 251 is a metabolite of Camostat and a pollen protease inhibitor for prevention and control of allergy.

Colchicine is a potent therapeutic tool against COVID-19. Colchicine is a tricyclic alkaloid that is extracted from the plant Colchicum autumnale. Colchicine acts as a potent inhibitor of tubulin polymerization.

GRL-1720 is an irreversible, covalent inhibitor of SARS-CoV-2 main protease (Mpro) with EC50 of 15 µM.

PF00835231(SARS-CoV-2 inhibitor 5h) is areversible-covalent inhibitor of SARS-CoV-2 main protease (Mpro) with EC50 of 4.2 µM. Compound 5h blocks the infectivity and cytopathicity of the virus with high potency and without any detectable cytotoxicity even at 200 µM.PF-00835231 is a potent inhibitor of CoV-2 3CLpro with IC50 of 4 nM and shows suitable pharmaceutical properties to warrant further development as an intravenous treatment for COVID-19.
