conclusions family history as well as baseline bilirubin, ast and hbv dna levels can predict early virological response. the model provides a better tool for response prediction based on the four prognostic factors. results negative family history of hbv infection (p = 0.000235), baseline higher serum tbil (p = 0.038714) and ast (p = 0.020684) concentrations, and lower level of hbv-dna (p = 0.0...

Telbivudine is an L-nucleoside analogue with potent antiviral activity against hepatitis B virus (HBV). Clinical trials have shown that telbivudine has a more potent and sustained antiviral activity with a lower frequency of viral resistance than lamivudine. Although there are several reports concerning the safety profile of telbivudine, most adverse events are described as mild and transient i...

FV100 is a promising new agent with extreme potency and specificity for varicella-zoster virus (VZV). It is the valyl ester pro-drug of Cf1743, the lead clinical candidate among the highly lipophilic bicyclic nucleoside analogue (BCNA) family discovered in Cardiff/Leuven. Cf1743 is unique amongst antivirals in terms of its structure and lipophilicity. It is exquisitely potent and selective for ...

The male genital tract is considered an anatomical reservoir during therapy for human immunodeficiency virus infection, because the blood-testis barrier may prevent antiretroviral drugs (e.g., the protease inhibitors ritonavir, saquinavir and nelfinavir) from entering the male genital tract. To our knowledge, there are currently no available data on the penetration of the nucleoside analogue ab...

Phosphonated isoxazolinyl nucleosides have been prepared via 1,3-dipolar cycloaddition reaction of nitrile oxides with corresponding vinyl or allyl nucleobases for antiviral studies. The cytotoxicity, the anti-HSV activity and the RT-inhibitory activity of the obtained compounds were evaluated and compared with those of AZT and diethyl{(1'SR,4'RS)-1'-[[(5-methyl-2,4-dioxo-3,4-dihydropyrimidin-1...

Acyclovir is a synthetic purine nucleoside analogue with in vitro and in vivo inhibitory activity against human herpes viruses including herpes simplex types 1 (HSV-1) and 2 (HSV2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV) and cytomegalovirus (CMV). In cell cultures, acyclovir has the highest antiviral activity against HSV-1, followed in decreasing order of potency against HSV-2, ...
