Vibrational spectra of molecules on zeolites. IV. Raman spectra of cyclopropane on zeolites X

open access: yes, 1978
Laser Raman spectra are reported for cyclopropane adsorbed on cation- exchanged zeolites X. The results have been interpreted in terms of an edge-on interaction of the cyclopropane molecule with the zeolitic cation site.

Bromonitroalkanes in Organic Synthesis

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
α,α‐Bromonitroalkanes (BNAs) exhibit chameleon‐like reactivity, serving as carbene, radical, carbanion, and carbocation synthons. This mini‐review summarizes the different reaction modes and highlights recent developments in thermal and photochemical processes. α,α‐Bromonitroalkanes (BNAs) exhibit chameleon‐like reactivity, serving as carbene, radical,

Thermodynamics and polarity-driven properties of fluorinated cyclopropanes

open access: yesBeilstein Journal of Organic Chemistry
Cyclopropane is a significant alicyclic motif, widely utilized in medicinal chemistry, while fluorination serves as a powerful tool to modulate properties that enhance the performance of pharmaceuticals and materials. This quantum-chemical study explores

The Discovery and Future Prospects of Artificial Porphyrins: Molecular Batteries Functioning with the Reversible Formation and Cleavage of Cyclopropane Units

open access: yesCHIMIA, 1996
The absence of the meso-hydrogen atoms in meso-octaalkylporphyrinogens enable the generation of novel forms of the oxidized porphyrinogen, 'artificial porphyrins'. A stepwise four-electron oxidation of meso-octaalkylporphyrinogen transitionmetal

SYNTHESIS, LSD1 INHIBITORY ACTIVITY, AND LSD1 BINDING MODEL OF OPTICALLY PURE LYSINE-PCPA CONJUGATES

open access: yesComputational and Structural Biotechnology Journal, 2014
Compounds that inhibit the catalytic function of lysine-specific demethylase 1 (LSD1) are interesting as therapeutic agents. Recently, we identified three lysine-phenylcyclopropylamine conjugates, NCD18, NCD25, and NCD41, which are potent LSD1 ...

TOLERANCE TO THE INDUCTION OF CARDIAC ARRHYTHMIAS BY ADRENALINE IN CYCLOPROPANE-ANAESTHETIZED DOGS

open access: yes, 1964
Long-continued maintenance of anaesthesia with cyclopropane has been reported to inhibit the induction of arrhythmias by adrenaline through an "adrenolytic effect".

Boronic Acid Inhibitors of β‐Lactamases: A Promising Strategy Against Antimicrobial Resistance

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT The rise of antimicrobial resistance (AMR) poses a critical threat to global health, mostly due to the proliferation of β‐lactamases, a class of enzymes responsible for the inactivation of β‐lactam antibiotics. Among the most promising strategies to restore β‐lactam efficacy is the use of β‐lactamase inhibitors (BLIs), with boronic acid ...

Main‐chain polyfullerenes: Taking fullerene to the next dimension

open access: yesPolymer International, EarlyView.
This short review appraises main‐chain polyfullerenes. Their slow development over 30 years has suddenly boomed with a rapid growth due to exciting developments in solar energy. Abstract This mini‐review gives an overview of the development, chemistry, properties and applications of main‐chain polyfullerenes.
