AbstractPyrimidine nucleosides are constituents of fundamental structure of the cells. There has been considerable attentions in the chemistry of pyrimidine derivatives due to having a wide range of biological activities such as antiviral, anti-malarial agents, cytostatic, antithelemintic, antibacterial, adenosine receptor ligands, anti-cancer agents, compounds targeting delayed-type hypersensi...

results it was found that the positive hepatitis b surface antigen (hbsag), the high baseline hbv dna level, the positive hepatitis b virus e antigen (hbeag), and an absent or low hepatitis b surface antibody (hbsab) titer prior to starting treatment are the most important viral risk factors. furthermore, rituximab, anthracycline, and different types of tnf-α inhibitors were identified as the h...

This multi-authored, comprehensive text on antiviral chemotherapy is the third edition of a book which was first published in 1979 and previously revised in 1984. The areas that have received the greatest revision in this edition, according to the editors, are the biophysics of drug development, the use of AZT for AIDS, ribavirin for respiratory syncytial virus infection, and DHPG for chemother...

Several hundred plant and herb species that have potential as novel antiviral agents have been studied, with surprisingly little overlap. A wide variety of active phytochemicals, including the flavonoids, terpenoids, lignans, sulphides, polyphenolics, coumarins, saponins, furyl compounds, alkaloids, polyines, thiophenes, proteins and peptides have been identified. Some volatile essential oils o...

Mucus is a porous biopolymer matrix that coats all wet epithelia in the human body and serves as the first line of defense against many pathogenic bacteria and viruses. However, under certain conditions viruses are able to penetrate this infection barrier, which compromises the protective function of native mucus. Here, we find that isolated porcine gastric mucin polymers, key structural compon...

PURPOSE OF REVIEW Long-acting antiretroviral (ARV) agents are currently under development for the treatment of chronic HIV infection. This review focuses on data recently produced on injectable ARVs for patients living with HIV/AIDS and on the patients' perspectives on the use of these agents. RECENT FINDINGS Crystalline nanoparticle formulations of the nonnucleoside reverse transcriptase inh...

Enteroviruses (EVs) are common human pathogens that are associated with numerous disease symptoms in many organ systems of the body. Although EV infections commonly cause mild or non-symptomatic illness, some of them are associated with severe diseases such as CNS complications. The current absence of effective vaccines for most viral infection and no available antiviral drugs for the treatment...

Approximately 120-130 million individuals are chronically infected with hepatitis C virus (HCV) worldwide, although it is curable by therapy. Until recently, treatment of chronic hepatitis C was based on the combination of pegylated interferon-α and ribavirin. A number of models have been developed to study the HCV lifecycle and screen for potential HCV inhibitors. They led to the development o...

Shrimp farming is an aquaculture business for the cultivation of marine shrimps or prawns for human consumption and is now considered as a major economic and food production sector as it is an increasingly important source of protein available for human consumption. Intensification of shrimp farming had led to the development of a number of diseases, which resulted in the excessive use of antim...

Cytomegalovirus (CMV) is a highly complex pathogen which, despite modern prophylactic regimens, continues to affect a high proportion of thoracic organ transplant recipients. The symptomatic manifestations of CMV infection are compounded by adverse indirect effects induced by the multiple immunomodulatory actions of CMV. These include a higher risk of acute rejection, cardiac allograft vasculop...
