Synthesis of 4,6-Difluoro-Tryptophan as a Probe for Protein 19F NMR
(Wiley-VCH GmbH, Weinheim, 2024-03-25)
A scalable procedure for the synthesis of 4,6-difluorotryptophan is reported based on a deaminative
coupling of a 4,6-difluorogramine with 2-benzylthio-1,5-dihydro-4H-imidazolone as glycine equivalent. Thus prepared ...
Development of an α’-hydroxy enone for the aminocatalytic asymmetric formal conjugate addition of aldehydes to acrylates, vinyl ketones and acrolein
(Royal Society of Chemistry, 2023-05-24)
Aminocatalytic asymmetric conjugate addition of aldehydes to Michael acceptors is a well established C–C bond forming methodology. However, various acrylic-type acceptors, including acrylic acid derivatives and acrolein, ...
Progress in (Thio)urea‐ and Squaramide‐Based Brønsted Base Catalysts with Multiple H‐Bond Donors
(Wiley, 2023-02)
Nowadays chiral (thio)urea- and squaramide-based Brønsted base catalysts are widely applied to enantioselective carbon-carbon and carbon-heteroatom bond forming reactions. In recent years, variations of these catalysts ...
Characterization of the Antitumor Potential of Extracts of Cannabis sativa Strains with High CBD Content in Human Neuroblastoma
(MDPI, 2023-02-14)
Cannabis has been used for decades as a palliative therapy in the treatment of cancer. This is because of its beneficial effects on the pain and nausea that patients can experience as a result of chemo/radiotherapy. ...
Crystallization-induced self-assembly of poly(ethylene glycol) side chains in dithiol–yne-based comb polymers: side chain spacing and molecular weight effects
(ACS, 2024-05)
The chain architecture and topology of macromolecules impact their physical properties and final performance, including their crystallization process. In this work, comb polymers constituted by poly(ethylene glycol), PEG, ...
Competition between O–H and S–H intermolecular interactions in conformationally complex systems: The 2-Phenylethanethiol and 2-Phenylethanol dimers
(ACS, 2024-05)
Noncovalent interactions involving sulfur centers play a relevant role in biological and chemical environments. Yet, detailed molecular descriptions are scarce and limited to very simple model systems. Here we explore the ...
Emissions generated by electric vehicles in the 9-500 kHz band: Characterization, propagation, and interaction
(Elsevier, 2024-06)
Electric Vehicle Charging Processes (EVCPs), due to the involved power electronics with high-switching frequencies, generate high-amplitude emissions that could have a negative impact on Power Quality (PQ) and Narrowband ...
Enhanced photosynthesis, transpiration regulation, water use-efficiency and growth in buckwheat outperforms wheat response to high [CO2], high temperature and drought
(Elsevier, 2024-06)
The rising atmospheric [CO2] levels will increase global temperature and drought events, threatening wheat (Triticum aestivum) production. In recent years, buckwheat (Fagopyrum esculentum) has emerged as an alternative ...
Ionic Liquid-Laden Zn-MOF-74-Based Solid-State Electrolyte for Sodium Batteries
(MDPI, 2023-12-12)
Sodium batteries are receiving increasing interest as an alternative to reduce dependence on lithium-based systems. Furthermore, the development of solid-state electrolytes will lead to higher-performing and safer devices. ...
Understanding the olfactory role in post-COVID cognitive and neuropsychiatric manifestations
(Frontiers Media, 2024)
Introduction: Olfactory dysfunction (OD) is frequent after SARS-CoV-2 infection. The aim of this study was to examine if long-term OD is common in post-COVID condition, and the relationship between olfaction, cognition, ...
