Protein Science, Volume 35, Issue 4, April 2026.Abstract The regio‐ and stereoselective hydroxylation of unactivated C(sp3)‐H bonds is an important reaction in organic synthesis. While bacterial alkane monooxygenase AlkB catalyzes the terminal hydroxylation of aliphatic esters with excellent regioselectivity, the molecular principles of substrate recognition and selectivity of this integral membrane

Journal of Food Science, Volume 91, Issue 4, April 2026.ABSTRACT Berries of Lonicera caerulea (blue honeysuckle; haskap) have been used since ancient times in traditional medicine in China, Japan, and northern Russia. This study aimed to extract, characterize, and evaluate the biological activity of iridoid‐rich fractions from haskap berries using an in vitro adipocyte model.

Bis‐Furans: A Sustainable Source of Diverse Molecular Architectures
European Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.A concise synthetic route to diverse acyclic and heterocyclic compounds has been developed by combining hetero‐Diels–Alder reactions, DBU‐promoted ring openings, and Lewis base‐catalyzed annulations. Nitrosoalkenes reacted with furan derivatives to form 4a,7a‐dihydro‐4H‐furo[2,3‐e][1,2]oxazines, which underwent DBU‐promoted rearrangements to 6H‐1,2 ...
