IHVR-17028

IHVR-17028 is a potent and broad-spectrum antiviral agent. IHVR-17028 exhibits antiviral activity against BVDV, TCRV and DENV with EC50 values of 0.4 μM, 0.26 μM, 0.3 μM, respectively. IHVR-17028 is a potent ER α-glucosidaseIinhibitor with an IC50 of 0.24 μM. IHVR-17028 can be used for infectious diseases research.

In virus yield reduction assays, IHVR-17028 inhibits viral activities with EC50 values of 0.4 μM, 0.26 μM, 0.3 μM for bovine viral diarrhea virus (BVDV) (NADL strain), tacaribe virus (TCRV) (11573 strain), DENV (serotype 2, New Guinea C), respectively. And in MTT assays, IHVR-17028 exhibits IC₅₀ values of all >500 μM in MDBK, Huh7.5 or BHK cells^[1].

In Pharmacokinetic analysis in rats, IHVR17028 (oral gavage; 75 mg/kg) shows a C_max value of 0.18 μg/ml; the Tmax value is 1.56 hours; and the F% value is 12% after PO administration, the T_1/2 value is 0.88 hour after iv. adminstration^[1].
IHVR-17028 (oral gavage; 25-50 mg/kg; treatment 1 day prior to virus challenging) exhibits significant protection in mouse model of lethal MARV infection^[1].
