Itraconazole (ITZ) is a well-known antifungal agent that also has anticancer activity. In this study, we identify ITZ as a broad-spectrum inhibitor of enteroviruses (e.g., poliovirus, coxsackievirus, enterovirus-71, rhinovirus). We demonstrate that ITZ inhibits viral RNA replication by targeting oxysterol-binding protein (OSBP) and OSBP-related protein 4(More)
UNLABELLED Scavenger receptor class B type I (SR-BI) is a high-density lipoprotein (HDL) receptor highly expressed in the liver and modulating HDL metabolism. Hepatitis C virus (HCV) is able to directly interact with SR-BI and requires this receptor to efficiently enter into hepatocytes to establish productive infection. A complex interplay between(More)
Hepatitis C virus (HCV) inhibitors include direct-acting antivirals (DAAs) such as NS3 serine protease inhibitors, nucleoside and nonnucleoside polymerase inhibitors, and host-targeting antivirals (HTAs) such as cyclophilin inhibitors that have been developed in recent years. Drug-resistant HCV variants have been reported both in vitro and in the clinical(More)
Chikungunya virus (CHIKV) is an Arbovirus that is transmitted to humans primarily by the mosquito species Aedes aegypti. Infection with this pathogen is often associated with fever, rash and arthralgia. Neither a vaccine nor an antiviral drug is available for the prevention or treatment of this disease. Albeit considered a tropical pathogen, adaptation of(More)
A chemical study of the Vietnamese plant species Trigonostemon howii led to the isolation of a new tigliane-type diterpenoid, trigowiin A (1), along with several known coumarins and phenylpropanoids. The planar structure and the relative configuration of compound 1 were elucidated based on spectroscopic analysis, including 1D- and 2D-NMR experiments, mass(More)
BACKGROUND & AIMS To delay or prevent the selection of HCV drug-resistant variants, combination therapy will be needed. Our aim was to determine the antiviral efficacy of various combinations of non-nucleoside polymerase inhibitors (NNI) (that have a different allosteric binding site) and the barrier towards resistance development of such combinations.

UNLABELLED Statins are 3-hydroxyl-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors used for the treatment of hypercholesterolemia. It was recently reported that statins inhibit in vitro hepatitis C virus (HCV) RNA replication. We here report that, of five statins studied, mevastatin and simvastatin exhibit the strongest in vitro anti-HCV activity,(More)
Chikungunya virus (CHIKV) is a re-emerging alphavirus that caused massive outbreaks of Chikungunya fever in several countries and regions in Africa, Asia and more recently in Central and South America. An acute CHIKV infection is usually associated with fever and arthritis and it is rarely fatal. However, 15-60% of patients suffer from chronic(More)
Hepatitis C virus (HCV) represents a major health burden, with an estimated 180 million chronically infected individuals worldwide. These patients are at increased risk of developing liver cirrhosis and hepatocellular carcinoma. Infection with HCV is the leading cause of liver transplantation in the Western world. Currently, the standard of care (SoC)(More)
The current standard of care (SOC) for hepatitis C virus (HCV) genotype 1-infected patients consists of telaprevir or boceprevir in addition to pegylated interferon and ribavirin treatment. Other selective inhibitors of HCV replication are being developed. Drug pressure may, depending on the class of inhibitors, (rapidly) select for drug-resistant variants.(More)
