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

open access: yesBrain 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

open access: yesMass 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.

Isolation and Characterization of Lactic Acid Bacteria From “Trites” Having the Ability to Produce α‐Glucosidase Inhibitors

open access: yesInternational Journal of Microbiology, Volume 2025, Issue 1, 2025.
Alpha‐glucosidase inhibitors are one of the therapies used for treating type 2 diabetes by inhibiting the absorption of carbohydrates in the gastrointestinal tract. In addition to antimicrobial activity, some probiotic species show α‐glucosidase inhibitor activity, making them potential alternative therapies for type 2 diabetes.

Generation of Molecular Complexity from Cyclooctatetraene: Preparation of Aminobicyclo[5.1.0]octitols [PDF]

open access: yes, 2015
A series of eight stereoisomeric N-(tetrahydroxy bicyclo-[5.1.0]oct-2S*-yl)phthalimides were prepared in one to four steps from N-(bicyclo[5.1.0]octa-3,5-dien-2-yl)phthalimide (±)-7, which is readily available from cyclooctatetraene (62 % yield).
