PC786 is a potent and selective non-nucleoside RSV L-protein polymerase inhibitor for inhalation therapy of RSV infections, with antiviral activity against RSV-A (IC50=0.09-0.71 nM) and RSV-B (IC 50=1.3-50.6 nM), and the ability to inhibit RSV RNA-dependent RNA polymerase in HEp-2 cells ( RdRp).

YM-53403 is an antiviral activity that effectively inhibits the replication of RSV strains belonging to subgroup A and subgroup B. It can be used to treat respiratory syncytial virus infections.

Syncytial Virus Inhibitor-1 is a potent, orally bioavailable inhibitor of respiratory syncytial virus (RSV) fusion, with EC50 values of 0.002 μM, 0.004 μM, and 0.002 μM for RSV Long, RSV A2, and RSV B strains, respectively.

Amentoflavone (3',8''-Biapigenin), as a potent inhibitor of CYP3A4 and CYP2C9, can interact with many other medications. CYP3A4 and CYP2C9 are proteins used for drug metabolism in the body. Amentoflavone also is an inhibitor of human cathepsin B. It has antimalarial activity in trials significant affinities towards the Delta-1, kappa opioid receptors (as an antagonist) and binds to benzodiazepine receptors. Amentoflavone may be a potential lead for a new type of anti-inflammatory agents having the dual inhibitory activity of group II phospholipase A2 and cyclooxygenase. Amentoflavone and quercetin differentially exerted suppression of PGE2 biosynthesis via downregulation of COX-2/iNOS expression.

Ribavirin-13C5is intended for use as an internal standard for the quantification of ribavirin by GC- or LC-MS. Ribavirin is an antiviral guanosine nucleoside analog.1,2Upon entry into cells, ribavirin is metabolized to an active triphosphate form that induces viral RNA chain termination and inhibits viral polymerases. It reduces replication in a panel of seven RNA and four DNA viruses in Vero cells (EC50s = 2-95 μg/ml).3Ribavirin also reduces replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Vero cells (EC50= 109.5 μM).4Aerosol administration of ribavirin (30 mg/kg) reduces mortality in a mouse model of influenza A infection.5Formulations containing ribavirin have been used in the treatment of respiratory syncytial virus (RSV), hepatitis C virus (HCV), and viral hemorrhagic fevers. 1.Gilbert, B.E., and Knight, V.Biochemistry and clinical applications of ribavirinAntimicrob.

RSV-IN-6 (Compound 53) is a specific inhibitor of the respiratory syncytial virus (RSV) that targets the M2-1 protein, demonstrating strong potency with EC50 values of 4.4 μM against RSV-A and 1.3 μM against RSV-B strains [1].

BMS-433771 dihydrochloride hydrate is a potent, orally active inhibitor of respiratory syncytial virus (RSV), effective against both group A and B strains with an average EC50 of 20 nM, and is utilized in researching respiratory tract diseases.

RSV604 ((S)-1-(2-Fluorophenyl)-3-(2-oxo-5-phenyl-2,3-dihydro-1H-benzo[e][1,4]diazepin-3-yl)urea) is an inhibitor of respiratory syncytial virus (RSV) that binds to RSV nucleoprotein (Kd = 1.31 μM)

Palivizumab (MEDI 493) is a humanized RSV-specific monoclonal antibody that selectively inhibits epitopes at the F protein A antigenic site of RSV subtypes A and B for the prevention of respiratory syncytial virus infection (RSV).
