Dengue Virus Molecular Targets and Antiviral Drug Development: Advances, Challenges and Therapeutic Perspectives

open access: yesChemistrySelect, Volume 11, Issue 33, 1 September 2026.
This narrative review analyzes DENV molecular targets, including structural proteins (C, prM/M, E), non‐structural components (NS1NS5), and host factors, alongside small‐molecule candidates in preclinical and clinical phases. Owing to high structural conservation, the NS2B‐NS3 protease and NS5 (RdRp/MTase) remain primary drug discovery focuses, while ...

Quantification and compensation of temporal decorrelation effects in polarimetric SAR interferometry [PDF]

open access: yes, 2012
Several studies showed that Pol-InSAR data especially at lower frequencies such as L- and P-band, are sensitive to the vertical distribution of scatterer along forest height.
