Biochem/physiol Actions

BAY41-4109 is a heteroaryldihydropyrimidine (HAP)-based capsid assembly modulator (CAM) that destabilizes hepatitis B virus (HBV) capsid assembly. BAY41-4109 inhibits HBV replication in HepG2.2.15 cultures with little host cytotoxicity (IC50 = 53 nM vs. CC50 = 7 μM in 8 days). Despite its relatively short half-life in vivo (plasma t1/2 = 5 h/dog, 2 h/rat, ≤1 h/mouse), BAY41-4109 shows greater antiviral efficacy than 3TC in Tg [HBV1.3 fsX-3′5′] mice (HBV DNA reduction = 52%/BAY vs. 36%/3TC in liver via 30 mg/kg b.i.d. p.o.; 70% vs. 30% in plasma with 15 mg BAY/kg or 30 mg/kg 3TC b.i.d. p.o., respectively) with good oral availability (F/tmax =31%/mouse, 58%/rat & dog).

Chronic hepatitis B virus (HBV) infection is a major cause of liver disease. Only interferon-alpha and the nucleosidic inhibitors of the viral polymerase, 3TC and adefovir, are approved for therapy. However, these therapies are limited by the side effects of

Hepatitis B virus (HBV) core protein assembles viral pre-genomic (pg) RNA and DNA polymerase into nucleocapsids for reverse transcriptional DNA replication to take place. Several chemotypes of small molecules, including heteroaryldihydropyrimidines (HAPs) and sulfamoylbenzamides (SBAs), have been discovered to allosterically

Current treatments for HBV chronic carriers using interferon alpha or nucleoside analogues are not effective in all patients and may induce the emergence of HBV resistant strains. Bay 41-4109, a member of the heteroaryldihydropyrimidine family, inhibits HBV replication by destabilizing

BAY 41-4109 is a member of a class of heteroaryl-pyrimidines that was recently identified as potent inhibitors of human hepatitis B virus (HBV) replication. We have investigated the antiviral activity of BAY 41-4109 (methyl (R)-4-(2-chloro-4-fluorophenyl)-2-(3,5-difluoro-2-pyridinyl)-6-methyl-1,4-dihydro-pyrimidine-5-carboxylate) in HBV-transgenic mice (Tg [HBV1.3

The HBV core protein represents an attractive target for new antiviral therapies due to its multiple functions within the viral life-cycle. Here, we report the antiviral activity of the capsid assembly modulator (CAM) BAY41-4109 and two nucleos(t)ide analogues (NAs) on
