Mefuparib(CVL218) hydrochloride is a potent, highly selective, competitive PARP1/2 inhibitor with IC50 of 3.2/1.9 nM, respectively.CVL218 was more potent than Remdesivir in blocking Coronavirus infection of cells and equally as potent as Remdesivir in blocking replication of virus once it has entered the cells.

DCAPI1594 Oseltamivir phosphate Featured

OSELTAMIVIR is an active (orally) inhibitor of the influenze virus neuraminidase and converted to the active acid metabolite in vivo.

DC11735 Remdesivir(GS-5734) Featured

Remdesivir is a novel RNA-dependent RNA Polymerase,(RdRp) inhibitor. The purity of remdesivir>99.8%,signal impurity<0.05%.

DC26208 Remdesivir metabolite(GS-441524) Featured

Remdesivir metabolite.Remdesivir blocks SARS-CoV and MERS-CoV in HAE cells with EC50s of both 74 Nm,and also showed potent activity blocking 2019-nCov(Coronavirus).

DC10662 GC-376 Featured

GC376 is a novel, first-in-class, small molecule protease inhibitor with a favorable therapeutic index demonstrated in preclinical studies. A common feature of viruses in the picornavirus-like supercluster (including coronaviruses) is a 3C or 3C-like protease (3Cpro or 3CLpro, respectively) responsible for viral replication. Viruses in this family include human coronavirus 229E, transmissible gastroenteritis virus of swine (TGEV), murine hepatitis virus (MHV), bovine coronavirus (BCV), feline infectious peritonitis virus (FIPV), severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East Respiratory Syndrome (MERS) and COVID-19 (SARS-CoV-2). GC376 has been shown to be a potent inhibitor of this protease across all coronaviruses with a high therapeutic index.

DC31011 R-Hydroxychloroquine Featured

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

DC31029 NHC(EIDD-1931) triphosphate Featured

NHC-triphosphate is an intracellular metabolite of β-d-N4-Hydroxycytidine (NHC) as a triphosphate form. NHC-triphosphate is a weak alternative substrate for the viral polymerase and changes the mobility of the product in polyacrylamide electrophoresis gels[1].

DC33651 ML188 Featured

ML188 is a Potent Noncovalent Small Molecule Inhibitor of the Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) 3CL Protease. The X-ray structure of SARS-CoV 3CLpro bound with ML188 was instrumental in guiding subsequent rounds of chemistry optimization. ML188 provides an excellent starting point for the further design and refinement of 3CLpro inhibitors that act by a noncovalent mechanism of action.

DC39024 AT-527 Featured

AT-527 is a novel compound for COVID-19 research. AT-527 is the hemi-sulfate salt of AT-511, a novel phosphoramidate prodrug of 2’-fluoro-2’-C-methylguanosine-5'-monophosphate that has potent in vitro activity against HCV. The EC50 of AT-511, determined using HCV laboratory strains and clinical isolates with genotypes 1–5, ranged from 5–28 nM. The active 5'-triphosphate metabolite, AT-9010, specifically inhibited the HCV RNA-dependent RNA polymerase. AT-527 is a novel modified guanosine nucleotide prodrug inhibitor of the hepatitis C virus (HCV) NS5B polymerase, with increased in vitro antiviral activity compared to sofosbuvir and a highly differentiated favorable preclinical profile compared to other anti-HCV nucleoside/nucleotide analogs. 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 SARS-CoV-2 by 90% (EC90) was 0.5 µM, very similar to the EC90 for AT-511 against HCoV-229E, HCoV-OC43 and SARS-CoV in Huh-7 cells. No cytotoxicity was observed for AT-511 in any of the antiviral assays up to the highest concentration tested (100 µM). Surprisingly, AT-511 was 30-fold less active against MERS-CoV. This differential activity may provide a clue to the apparent unique mechanism of action of the guanosine triphosphate analog formed from AT-527.

DC39042 FGI-106 Featured

FGI-106 tetrahydrochloride is a potent and broad-spectrum inhibitor with inhibitory activity against multiple viruses. FGI-106 tetrahydrochloride is active against Ebola, Rift Valley and Dengue Fever viruses with EC50s of 100 nM, 800 nM and 400-900 nM, respectively. FGI-106 tetrahydrochloride also inhibits non-hemorrhagic fever viruses HCV and HIV-1 with EC50s of 200 nM and 150 nM, respectively[1].FGI-106 is a potent compound for COVID-19 treament.

DC39053 XP-59 Featured

XP-59 is a potent inhibitor of the SARS-CoV Mpro, with a Ki of 0.1 μM[1].The SARS-CoV main proteinase (Mpro) plays a central role in the formation of the viral replicase/transcriptase complex and is thus an ideal target for the development of suitable drugs[1].

DC39115 LCB-1 protein Featured

LCB-1 is a designed antiviral protein inhibiting SARS-CoV-2. LCB1 is roughly six times more potent on a per mass basis than the most effective monoclonal antibodies reported thus far.LCB1 is currently being evaluated in rodents. LCB1 binds the Spike receptor binding domain (RBD) with affinity below 1 nM and blocks ARS-CoV-2 infection of Vero E6 cells with IC50 of 23.54 pM.
