Biotin modification of SBP1.SBP1(spike-binding peptide 1) is a first-in-class peptide binder to the SARS-CoV-2 spike protein. SBP1 specifically binds SARS-CoV-2-RBD with low nanomolar affinity. SBP1 to the RBD was determined to be 47 nM with the average Kon = 4.69*104M-1S-1 and Koff=2.2*10-3.The interaction between SBP1 and the RBD of SARS-CoV-2 spike protein was validated by bio-layer interferometry. The KD, derived from protein association and dissociation kinetics, was found to be 47 nM after averaging the fitting values at different protein concentrations. The amino acid sequence of SBP1 is entirely derived from human ACE2 and should be recognized as endogenous by the human immune system. This feature could be highly beneficial in later stages of pre-clinical development.

GRP-60367 is a first-in-class direct-acting RABV inhibitor with EC50 from 2 to 52 nM (different host cell lines) that blocks RABV G protein-mediated viral entry.

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.

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.

Sisunatovir (RV521), an orally available inhibitor of the RSV fusion (RSV-F) protein, exhibits potent efficacy against a panel of clinical isolates of RSV-A and RSV-B viruses, with IC50s of 1.4 nM and 1.0 nM, respectively.

Sisunatovir, also known as RV521, is a highly potent fusion inhibitor with efficacy against a panel of clinical isolates of RSV-A and RSV-B viruses. RV521 exhibited a mean IC50 of 1.2 nM against a panel of RSV A and B laboratory strains and clinical isolates with antiviral efficacy in the Balb/C mouse model of RSV infection. Oral bioavailability in preclinical species ranged from 42 to >100% with evidence of highly efficient penetration into lung tissue. In healthy adult human volunteers experimentally infected with RSV, a potent antiviral effect was observed with a significant reduction in viral load and symptoms compared to placebo.
