The prodrug strategy has been frequently employed as a chemical approach for overcoming the disadvantages of existing parent drugs. In this report, we synthesized four monoester prodrugs of ganciclovir, an anticytomegalovirus drug, and demonstrated t

To improve the efficiency of gene delivery for effective gene therapy, it is essential that the vector carries functional components that can promote overcoming barriers in various steps leading to the transport of DNA from extracellular to ultimatel

The purpose of this study was to improve the membrane permeability and oral absorption of the poorly permeable anti-influenza agent, zanamivir. The poor oral bioavailability is attributed to the high polarity (cLogP ∼ -5) resulting from the polar a

Enhanced in vivo gene expression using non-viral vectors is a critical issue in gene therapy in general. Among the many potential utilities of non-viral vector-mediated gene delivery, its application in DNA-based vaccination is an attractive approach

One of the most important requirements for non-viral gene delivery systems is the ability to mediate high levels of gene expression with low toxicity. After the DNA/vector complexes are taken up by cells through endocytosis, DNA is typically containe

Chemical modification to improve biopharmaceutical properties, especially oral absorption and bioavailability, is a common strategy employed by pharmaceutical chemists. The approach often employs a simple structural modification and utilizes ubiquito

Human plasmacytoid dendritic cells (PDCs) can produce interferon (IFN)-alpha and/or mature and participate in the adaptive immune response. Three classes of CpG oligonucleotide ligands for Toll-like receptor (TLR)9 can be distinguished by different s

Background A major obstacle to achieving effective DNA-based therapeutics is efficient delivery of the DNA to its site of action in the cell. Upon internalization by endocytosis, the endosomal membrane represents a critical physical barrier preventin

Delivery of macromolecules into the cytosolic space of eukaryotic cells is a pressing challenge in biopharmaceutics. Macromolecules are often encapsulated into liposomes for protection and improved distribution, but the their size often induces endoc

Delivery of antigenic protein to the cytosol of antigen-presenting cells (APCs), such as macrophages (MPhi) and dendritic cells (DCs), is required for an efficient CD8 T-cell-mediated immune response. We have previously shown that co-encapsulation of
