Initiation of Vancomycin Therapy and the First Therapeutic Drug Monitoring
2021
Abstract There have been a limited number of studies in Latvia that were focused on vancomycin therapeutic drug monitoring (TDM), especially during the initiation phase of the therapy. The aim of this study was to investigate details of vancomycin therapy in its initiation phase and to analyse the results of the first therapeutic drug monitoring within a multidisciplinary hospital in Latvia. A retrospective observational study was performed in a multidisciplinary hospital in Latvia. Adult patients hospitalised in an intensive care unit and undergoing vancomycin therapy with at least one concentration measurement were included in this study. Data about patients included demographic and clini…
Imidazolium and Potassium Hydrogen Carbonate Salts as Ecofriendly Organocatalysts for Oxazolidinone Synthesis
2016
International audience; Although oxazolidinones are valuable intermediate compounds for industrial applications, no synthetic method is suitable for their production on a large scale owing to the use of reagents/catalysts that are hazardous or toxic to human health or ecotoxic for the environment. In this manuscript, we describe new and efficient catalysts, that is, the nontoxic hydrogen carbonate anion in combination with a potassium or diisobutylimidazolium ([iBu(2)IM]) countercation, for the conversion of -amino alcohols into cyclic oxazolidinones in high yields of 69 to 90%. Depending on the catalytic conditions, both catalysts could be easily recovered from the crude reaction products …
Pectin: A Long-Neglected Broad-Spectrum Antibacterial.
2020
First reported in the late 1930s and first partly explained in 1970, the antibacterial activity of pectin remained almost ignored until the late 1990s. The concomitant emergence of research on natural antibacterials and on new usages of pectin polysaccharides, including those in medicine widely researched in Russia, has led to a renaissance of research in the physiological properties of this uniquely versatile polysaccharide ubiquitous in plants and fruits. Collecting scattered information, this study provides an updated overview on the subtle factors affecting the behaviour of pectin as antimicrobial. Less degraded pectin extracted via acid-free routes, we argue in the conclusions, will so…
Pyrrolidine in Drug Discovery: A Versatile Scaffold for Novel Biologically Active Compounds
2021
AbstractThe five-membered pyrrolidine ring is one of the nitrogen heterocycles used widely by medicinal chemists to obtain compounds for the treatment of human diseases. The great interest in this saturated scaffold is enhanced by (1) the possibility to efficiently explore the pharmacophore space due to sp3-hybridization, (2) the contribution to the stereochemistry of the molecule, (3) and the increased three-dimensional (3D) coverage due to the non-planarity of the ring—a phenomenon called “pseudorotation”. In this review, we report bioactive molecules with target selectivity characterized by the pyrrolidine ring and its derivatives, including pyrrolizines, pyrrolidine-2-one, pyrrolidine-2…
