Topical Collection Information

Dear colleague,

Estonian researchers of different backgrounds (pharmacists, pharmacologists, gene technologists, physicist, chemists, material scientists, etc.) are conducting research in the field of pharmaceutical sciences and technology. Hence, several researchers in Estonia are the leaders of their field and continue to have an enormous impact on the development of pharmaceutical research globally. Several success stories in academia as well as in industry can be presented. For example, recent notable progress has been made on the development of novel drugs for the treatment of COVID-19 in Estonia. Furthermore, pharmaceutical applications of nanomaterials and nanotechnology have enabled the delivery of macromolecules, including RNA, DNA, proteins, and peptides (e.g., cell-penetrating peptides and tumor-penetrating peptides) as well as small-molecule drugs.

This topical collection will highlight the research in pharmaceutical sciences and technology currently ongoing in Estonia, both within academic and industrial institutions, in areas including but not limited to drug discovery and development, drug delivery, pharmacokinetics, drug metabolism and drug transport, physical pharmacy, pharmacogenomics and personalized medicine, pharmacy practice research, pharmacoepidemiology, and pharmaceutical natural products. 

This will be achieved by presenting a topical collection of research papers and review articles covering the recent progress and achievements in high-end pharmaceutical science.

Due to the high prevalence of infectious diseases and their concurrent outbreaks, there is a high interest in developing novel materials with antimicrobial properties. Antibacterial and antiviral properties of a range of metal-based nanoparticles (NPs) are a promising means to fight airborne diseases caused by viruses and bacteria. The aim of this study was to test antimicrobial metals and metal-based nanoparticles efficacy against three viruses, namely influenza A virus (H1N1; A/WSN/1933) and coronaviruses TGEV and SARS-CoV-2; and two bacteria, Escherichia coli and Staphylococcus aureus. The efficacy of ZnO, CuO, and Ag NPs and their respective metal salts, i.e., ZnSO4, CuSO4, and AgNO3, was evaluated in suspensions, and the compounds with the highest antiviral efficacy were chosen for incorporation into fibers of cellulose acetate (CA), using electrospinning to produce filter materials for face masks. Among the tested compounds, CuSO4 demonstrated the highest efficacy against influenza A virus and SARS-CoV-2 (1 h IC50 1.395 mg/L and 0.45 mg/L, respectively), followed by Zn salt and Ag salt. Therefore, Cu compounds were selected for incorporation into CA fibers to produce antiviral and antibacterial filter materials for face masks. CA fibers comprising CuSO4 decreased SARS-CoV-2 titer by 0.38 logarithms and influenza A virus titer by 1.08 logarithms after 5 min of contact; after 1 h of contact, SARS-COV-2 virus was completely inactivated. Developed CuO- and CuSO4-based filter materials also efficiently inactivated the bacteria Escherichia coli and Staphylococcus aureus. The metal NPs and respective metal salts were potent antibacterial and antiviral compounds that were successfully incorporated into the filter materials of face masks. New antibacterial and antiviral materials developed and characterized in this study are crucial in the context of the ongoing SARS-CoV-2 pandemic and beyond. Full article

Intrinsic aqueous solubility is a foundational property for understanding the chemical, technological, pharmaceutical, and environmental behavior of drug substances. Despite years of solubility research, molecular structure-based prediction of the intrinsic aqueous solubility of drug substances is still under active investigation. This paper describes the authors’ systematic data-driven modelling in which two fit-for-purpose training data sets for intrinsic aqueous solubility were collected and curated, and three quantitative structure–property relationships were derived to make predictions for the most recent solubility challenge. All three models perform well individually, while being mechanistically transparent and easy to understand. Molecular descriptors involved in the models are related to the following key steps in the solubility process: dissociation of the molecule from the crystal, formation of a cavity in the solvent, and insertion of the molecule into the solvent. A consensus modeling approach with these models remarkably improved prediction capability and reduced the number of strong outliers by more than two times. The performance and outliers of the second solubility challenge predictions were analyzed retrospectively. All developed models have been published in the QsarDB.org repository according to FAIR principles and can be used without restrictions for exploring, downloading, and making predictions.
