L‐quebrachitol Modulates the Anti‐convulsant Effects of Carbamazepine Possibly Through Voltage‐gated Sodium Channel Blocking Mechanism in Chicks: In Vivo and In Silico Studies

Brain and Behavior, Volume 15, Issue 7, July 2025.
L‐quebrachitol exhibited significant anticonvulsant effects in PTZ‐induced seizures in chicks, likely through voltage‐gated sodium channel inhibition. In vivo and in silico analyses suggest LQB may synergize with carbamazepine, offering a potential new therapeutic approach for epilepsy management. ABSTRACT Introduction L‐Quebrachitol (LQB), a naturally

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Complexes of carbohydrates with metal cations. IV. Cyclitols

, 1975
Cyclitols which contain an axial-equatorial-axial sequence of three hydroxyl groups form complexes with cations. Complex formation can be detected by the downfield shifts of the signals in their p.m.r. spectra; the signal of the hydrogen atom attached to

Determination of the structures of four new isomeric cyclitols

, 2004
A series of impurities, which were all of the same molecular formula, C17H33NO7, were obtained in the process of voglibose synthesis. After isolation and purification, four isomeric cyclitols were completely assigned by 2D NMR experiments.

Recent Advances in Sustainable Total Synthesis and Chiral Pool Strategies with Emphasis on (−)‐Sclareol in Natural Products Synthesis

European Journal of Organic Chemistry, Volume 28, Issue 8, February 24, 2025.
There are continuous efforts to improve total syntheses of natural products, particularly their sustainability, such as developing effective chiral pool approaches relying on a wide spectrum of natural chirons, including (−)‐sclareol as one of the most useful natural chirons.

Bio-inspired synthesis of rare and unnatural carbohydrates and cyclitols through strain driven epimerization

, 2014
We report a bio-inspired, strain driven epimerization of trans-ketals to cis-ketals through an enolate intermediate. Swern oxidation of a hydroxyl group adjacent to a trans-ketal effects both oxidation and its epimerization to cis-ketal.

Cyclitols: Conduritols and related compounds

, 2004
Conduritols are 1,2,3,4-cycloliexenetetrol isomers and exist in ten possible isomeric forms (two meso-four DL-pairs) and have been labelled A, B, C, D, E and F. All of the possible conduritol isomers have already been synthesised starting from completely
