Solvolysis of exo- and endo-Tricyclo[3,3,0,02,8]oct-3-yl p-Nitrobenzoates

open access: yes, 1974
exo- and endo-Tricyclo[3,3,0,02.8]octan-3-ols (7a) and (8a) have been prepared and their structure elucidated. Solvolysis of the derived p-nitrobenzoate of the endo alcohol in 70% aqueous acetone at 100 occurred some ten times faster than the p ...

First Report on the Phytochemical and Pharmacological Properties of Hedysarum yilmazunalii

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Hedysarum yilmazunalii was collected from Erzincan, Türkiye. The leaf, stem, and root parts were then used for methanolic extraction. The extracts were analyzed for their phytochemical composition by LC–MS/MS and tested for antioxidant, enzyme inhibitory, and antiproliferative activities.

Progress in Synthesis and Pharmacology of Telmisartan

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Telmisartan is a benzimidazole derivative and a well‐known drug to treat hypertension. This review provides synthesis and understanding of telmisartan as an antihypertensive drug through two mechanisms of actions: RAAS inhibitor and PPARγ receptor. Effective repurposing of this drug for various diseases like chronic kidney illness, diabetes, fatty ...

Sulfonamide‐Based 2‐Amino‐1,3,4‐Oxadiazole Derivatives as Dual Cholinesterase and Carbonic Anhydrase Inhibitors: Design, Synthesis, Kinetic Characterization, Molecular Modeling, and ADMET Evaluation

open access: yesDrug Development Research, Volume 87, Issue 6, September 2026.
ABSTRACT In this study, 12 novel sulfonamide derivatives incorporating 2‐amino‐1,3,4‐oxadiazole and 1,3‐benzazol‐2(3H)‐one scaffolds were synthesized and structurally characterized using 1H NMR, 13C NMR, and LC–MS analyses. Their inhibitory activities were evaluated against acetylcholinesterase (AChE), butyrylcholinesterase (BChE), carbonic anhydrase I

Stereoselective Higher‐Order [10+4]‐ and [10+6] Cycloadditions Between Two Highly Unsaturated and Ambiphilic π‐Addends

open access: yesChemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
Aminocatalytically generated isobenzofulvenes and 3‐oxidopyridinium betaines act as ambiphilic reaction partners in orbital‐symmetry‐allowed [10+4] cycloadditions or formally symmetry‐forbidden concerted thermal [10+6] cycloadditions. The reaction furnishes three cycloadducts: one [10+4] cycloadduct and two regioisomeric [10+6] cycloadducts.
