The absence of any formally licensed antiadenovirus drugs and the increasing incidence of life-threatening adenovirus infections in immunosuppressed patients warrant the development of effective antiadenovirus compounds. A detailed study was performed on the antiadenovirus activities of several classes of nucleoside and nucleotide analogues in human embryonic lung fibroblast cells. The antiaden...
We recently demonstrated that lactoferrin, an antimicrobial glycoprotein, can inhibit adenovirus infection by competing for common glycosaminoglycan receptors. This study further characterizes the antiadenovirus activity of the protein, thus demonstrating that lactoferrin neutralizes infection by binding to adenovirus particles and that its targets are viral III and IIIa structural polypeptides.
Animal studies indicate that the use of replication-deficient adenovirus for human gene therapy is limited by host antivector immune responses that result in transient recombinant protein expression and blocking of gene transfer when rechallenged. Therefore, we have examined immune responses to an adenoviral vector and to the beta-galactosidase protein in four patients with lung cancer given a ...
The importance of human adenovirus infections in immunocompromised patients urges for new and adequate antiadenovirus compounds. Since human adenoviruses are species specific, animal models for systemic adenovirus infections rely on a nonhuman adenovirus. We established mouse adenovirus type 1 (MAV-1) infection of BALB/c SCID mice as a model for the evaluation of antiadenovirus therapy. In vitr...
background and aims: human adenoviruses can cause a diversity of clinical diseases, but there is no antiviral therapy formally approved by adenovirus infections. thus, antiviral agents derived from medicinal plants which are effective against adenoviruses infections are urgently required. therefore, this research was aimed to evaluate in vitro antiadenovirus activity of pomegranate (punica gran...
Nitric oxide (NO) is an antiviral effector of the innate immune system, but few of the viral targets of NO have been identified. We now show that NO inhibits adenovirus replication by targeting the adenovirus proteinase (AVP). NO generated from diethylamine NONOate (DEA-NONOate) or spermine NONOate (Sp-NONOate) inhibited the AVP. Inhibition was reversible with dithiothreitol. The equilibrium di...
A new 4D-QSAR approach has been considered. For all investigated molecules the 3D structural models have been created and the set of conformers (fourth dimension) have been used. Each conformer is represented as a system of different simplexes (tetratomic fragments of fixed structure, chirality and symmetry). The investigation of influence of molecular structure of macrocyclic pyridinophanes, t...
