Selective transformations of friedelanes isolated from cork smoker wash solids
(Elsevier, 2024)Friedelin (1) and 3-acetoxyfriedel-3-en-2-one (4), commonly known as friedelane triterpenoids, have been isolated from cork smoker wash solids (also known as black wax) on a multi-gram scale. These compounds are valuable ... -
Spectroscopic and Crystallographic Characterization of Two Hydrochloride Cathinones: 1-(4-fluoro-3-methylphenyl)-2-(pyrrolidin-1-yl)pentan-1-one (4-F-3-Me-α-PVP) and N-ethyl-2-amino-1-phenylheptan-1-one (N-ethylheptedrone)
(MDPI, 2023)In this paper, two cathinone derivatives, 4F-3Me-alfa-PVP and N-ethylheptedrone, seized on the illegal drug market in Poland, were described and characterized by various instrumental analytical methods. The compounds were ... -
The magic of biaryl linkers: the electronic coupling through them defines the propensity for excited-state symmetry breaking in quadrupolar acceptor–donor–acceptor fluorophores
(Royal Society of Chemistry, 2023)Charge transfer (CT) is key for molecular photonics, governing the optical properties of chromophores comprising electron-rich and electron-deficient components. In hotoexcited dyes with an acceptor–donor–acceptor or ... -
Unprecedented 1,2-Aryl Shift Accompanying Double Alkyne Benzannulation
(Wiley, 2023)The tandem intramolecular hydroarylation of alkynes accompanied by a 1,2-aryl shift is described. Harnessing the unique electron-rich character of 1,4-dihydropyrrolo[3,2-b]pyrrole scaffold, we demonstrate that the ... -
Enzymatic Synthesis of a Novel Coumarin Aminophosphonates: Antibacterial Effects and Oxidative Stress Modulation on Selected E. coli Strains
(MDPI, 2023)The objective of the present study was to evaluate the synergistic effect of two important pharmacophores, coumarin and -amino dimethyl phosphonate moieties, on antimicrobial activity toward selected LPS-varied E. coli ... -
Interdisciplinary approach to synthesis, stability and antimicrobial activity of silver nanoparticles
(Termedia sp. z o.o., 2023)Chronic wounds are an increasing problem for health care all over the world. New treatment options for this illness are desired, especially antimicrobial agents. Silver nanoparticles (AgNPs) can be a potential substance ... -
Magnetic Antiaromaticity─Paratropicity─Does Not Necessarily Imply Instability
(ACS Publications, 2023)Magnetically induced ring currents are a conventional tool for the characterization of aromaticity. Dia- and paratropic currents are thought to be associated with stabilization (aromaticity) and destabilization (antiaromaticity), ... -
Realization of nitroaromatic chromophores with intense two-photon brightness
(Royal Society of Chemistry, 2023)Strong fluorescence is a general feature of dipyrrolonaphthyridinediones bearing two nitrophenyl substituents. Methyl groups simultaneously being weakly electron-donating and inducing steric hindrance appear to be a key ... -
