In the arbovirus family of flaviviruses, the important non-structural enzyme that is RNA-dependent RNA-polymerase (NS5 RdRp) is vital for replication. The normal mammalian host lack this enzyme, thus targeting this enzyme for drug discovery against Flaviviridae related infection makes it a suitable target. In this work, effective non-nucleoside blockers of the dengue NS5 (RdRp) were used to target the zika virus. Molecular interactions between selected compounds and the non-structural enzyme 5 RNA-dependent RNA-polymerase were obtained from molecular docking. The selected compounds exhibited high docking score, binding affinity and suitable protein-ligand interactions. Molecular dynamics simulations were subsequently used to get better idea of the interaction between the selected compounds and the binding pocket of the targeted non-structural-5 RNA dependent RNA polymerase of zika virus. Our study highlights the significance of in silico methods that provided a better approach in finding novel drugs for the containment of this viral disease. (C) 2019 Elsevier B.V.

Pyrolysis kinetics of bio-based polyurethane: Evaluating the kinetic parameters, thermodynamic parameters, and complementary product gas analysis using TG/FTIR and TG/GC-MS

Chen Xinyang, Cai Di, Yang Yumiao, Sun Yuhang, Wang Binhui, Yao Zhitong, Jin Meiqing, Liu Jie, Markus Reinmoller, Syed Lal Badshah, Aneta Magdziarz

Summary: The pyrolysis behavior and reaction kinetics of bio-based polyurethane (BPU) were investigated and compared to its components enzymatic lignin (EL) and polyurethane (PU). The findings showed that the decomposition of BPU was similar to PU, but the addition of EL improved BPU's thermal resistance. Both PU and BPU released N-containing compounds during pyrolysis, but phenols and furans were detected only during BPU pyrolysis. The activation energy of BPU was determined to be 176.1 kJ mol-1, which was smaller than that of EL (298.5 kJ mol-1) and larger than that of PU (159.5 kJ mol-1).
