Eckol inhibits ultraviolet B-induced cell damage by a decrease in oxidative stress in human keratinocytes.This compound is unstable in powder form and other related salt forms are recommended.
Influenza A virus-IN-1, a dihydropyrrolidones derivative, is a highly effective inhibitor of various subtypes of influenza A virus (IAV) with IC 50 values ranging from 3.11 μM to 7.13 μM. It effectively suppresses IAV replication and enhances the expression of key antiviral cytokines, such as IFN-β, and the antiviral protein MxA.
DPQ is an antiviral compound. DPQ has also been shown to bind to a widened RNA major groove at the internal loop. DPQ acts against the H1N1 and H3N2 strains of influenza A as well as influenza B.
MBX2546 is an Influenza A Virus Fusion Inhibitor. MBX2546 binds to HA and inhibits HA-mediated membrane fusion. Both binding and stabilization of HA by MBX2546 are required for the inhibition of viral infection. Mutations in MBX2546-resistant influenza A
Methyl brevifolincarboxylate (Brevifolincarboxylic acid methyl ester) is a potent influenza virus PB2 cap-binding inhibitor. Methyl brevifolincarboxylate exhibits inhibitory activity against influenza virus A Puerto Rico 8 34 (H1N1) and A Aichi 2 68 (H3N2) with IC50s of 27.16 μM and 33.41 μM. Anti-oxidant activity[1][2]. Methyl brevifolincarboxylate exhibits significant DPPH radical scavenging activity with an IC50 value of 8.9 μM. [1]. Wu QY, et al.
