Abstract: The rapid mutability of influenza virus in conjunction with genomic reassortment between viral strains promotes the virus' ability to evade vaccines and to become resistant to antiviral drugs. Therefore, novel anti-influenza therapeutics utilizing new targets and creative strategies are essential. The RNA-dependent RNA polymerase of the virus consists of PA, PB1, and PB2 subunits. Biological and structural investigations of the functional domains of these subunits have broadened the target reservoir for drug screening. With the wealth of knowledge from these studies, identification of small-molecule inhibitors that specifically disrupt the polymerase assembly or abrogate polymerase activities has emerged as an innovative and promising approach. In an attempt to facilitate the discovery of antiviral agents that target viral polymerase, isolated functional domains such as the PA endonuclease domain, the PB2 cap-binding domain, and the PA-PB1 interaction domains were expressed as screening targets. Based on the biochemical and structural properties of individual targets, a variety of platforms were established for the effective screening of inhibitors, including systematic evolution of ligands by exponential enrichment (SELEX), fluorescence resonance energy transfer (FRET) assay, fluorescence polarization (FP) assay, and enzyme-linked immunosorbent assay (ELISA). The antiviral efficacies of selected inhibitors were examined in vitro and in vivo, followed by verification of their antiviral mechanisms. Clinical merits of selected inhibitors were further evaluated, focusing mainly on their cross-protection abilities among influenza virus subtypes and their potential synergetic antiviral effects when used in combination with other drugs. A number of small-molecule compounds, i.e. PA-30, ANA-0, PB2-19, PAC-3 and ANA-1, together with the aptamer PAN-2, were identified as potent inhibitors against the replication of multiple subtypes of influenza A virus, including H1N1, H3N2, H5N1, H7N7, H7N9, and H9N2, in Madin-Darby canine kidney (MDCK) cell cultures. The intranasal administration of the identified compounds enhanced survival rates and reduced lung viral loads in BALB/c mice infected with H1N1 virus. The docking analyses predicted the compounds targeting PA or PB2 interacted with enzyme active sites to abolish endonuclease or cap-binding activity of the polymerase, whereas the compound targeting the PA-PB1 interaction likely induced configurational changes that impeded polymerase assembly. In addition, the combined treatment of zanamivir with the PA- or PB2-targeted compounds exerted synergistic antiviral effects in vitro. This study underscores the medical importance of polymerase functional domains as druggable targets, which may be due to the fact that these targeted areas are not only highly conserved among virus subtypes but also key to viral fitness. The identified antivirals exhibit substantial promise for clinical applications and provide new additions to the arsenal of drugs that are already used for chemoprophylaxis and treatment of influenza. Importantly, the established screening platforms for PA endonuclease inhibitors, PB2 cap-binding inhibitors, and PA-PB1 interaction disrupters should advance the development of a category of anti-influenza drugs that target viral polymerase.

Tagging of gene products with fluorescent proteins has revolutionized all areas of biosciences, ranging from fundamental biochemistry to clinical oncology, to environmental research. The discovery of the Green Fluorescent Protein, its first, seminal application and the ingenious development of a broad palette of fluorescence proteins of other colours, was consequently recognised with the Nobel Prize for Chemistry in 2008. Fluorescent Proteins II highlights the physicochemical and biophysical aspects of fluorescent protein technology beyond imaging. It is tailored to meet the needs of physicists, chemists and biologists who are interested in the fundamental properties of fluorescent proteins, while also focussing on specific applications. The implementations described are cutting-edge studies and exemplify how the physical and chemical properties of fluorescent proteins can stimulate novel findings in life sciences.

Download or read book Advanced Imaging and Bio Techniques for Convergence Science written by Jun Ki Kim and published by Springer Nature. This book was released on 2021-04-08 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a wide-ranging guide to advanced imaging techniques and related methods with important applications in translational research or convergence science as progress is made toward a new era in integrative healthcare. Conventional and advanced microscopic imaging techniques, including both non-fluorescent (i.e., label-free) and fluorescent methods, have to date provided researchers with specific and quantitative information about molecules, cells, and tissues. Now, however, the different imaging techniques can be correlated with each other and multimodal methods developed to simultaneously obtain diverse and complementary information. In addition, the latest advanced imaging techniques can be integrated with non-imaging techniques such as mass spectroscopic methods, genome editing, organic/inorganic probe synthesis, nanomedicine, and drug discovery. The book will be of high value for researchers in the biological and biomedical sciences or convergence science who need to use these multidisciplinary and integrated techniques or are involved in developing new analytical methods focused on convergence science.
