Saturated Cannabinoids: Update on Synthesis Strategies and Biological Studies of These Emerging Cannabinoid Analogs

open access: yesMolecules, 2023
Natural and non-natural hexahydrocannabinols (HHC) were first described in 1940 by Adam and in late 2021 arose on the drug market in the United States and in some European countries.

Electrochemical properties of quinones, antraquinones and their derivatives – potential redox-systems for flow batteries [PDF]

open access: yesЭлектрохимическая энергетика, 2021
Practical interest in redox flow batteries has arisen in recent decades as a result of intensive development in the field of alternative energy (such as solar and wind) and the control of peak loads in industrial electrical networks.

Construction of Exact Solutions to Nahm's Equations for the Multimonopole [PDF]

open access: yes, 2022
We construct high rank solutions to Nahm's equations for boundary conditions that correspond to the Dirac multimonopole. Here, the spectral curve is explicitly known and we achieve the integration by constructing a basis of polynomial tuples that forms a frame for the flow of the eigenline bundle over the curve.

Residual Larvicidal Activity of Quinones against Aedes aegypti

open access: yesMolecules, 2020
The number of documented dengue cases has increased dramatically in recent years due to transmission through the Aedes aegypti mosquito bite. Vector control remains the most effective measure to protect against this and other arboviral diseases including

Features of idebenone and related short-chain quinones that rescue ATP levels under conditions of impaired mitochondrial complex I. [PDF]

open access: yesPLoS ONE, 2012
Short-chain quinones have been investigated as therapeutic molecules due to their ability to modulate cellular redox reactions, mitochondrial electron transfer and oxidative stress, which are pathologically altered in many mitochondrial and neuromuscular

Development of a hybrid flow battery layout based on the derivatives of quinones and anthraquinones in alkaline solutions [PDF]

open access: yesЭлектрохимическая энергетика, 2023
Practical interest in redox flow batteries (RFB) has arisen in recent decades due to the intensive development of alternative energy (such as solar and wind) and the regulation of peak loads in industrial electrical networks.

Mini Review of Phytochemicals and Plant Taxa with Activity as Microbial Biofilm and Quorum Sensing Inhibitors

open access: yesMolecules, 2015
Microbial biofilms readily form on many surfaces in nature including plant surfaces. In order to coordinate the formation of these biofilms, microorganisms use a cell-to-cell communication system called quorum sensing (QS).

Quinones from Cordia species from 1972 to 2023: isolation, structural diversity and pharmacological activities

open access: yesNatural Products and Bioprospecting, 2023
Plants of the genus Cordia (Boraginaceae family) are widely distributed in the tropical regions of America, Africa, and Asia. They are extensively used in folk medicine due to their rich medicinal properties. This review presents a comprehensive analysis
