Article Abstract
A N-heterocyclic carbene-catalyzed (NHC) three-component reaction involving -aminopyridinium salts, alkenes, and aldehydes for the synthesis of β-amino ketones is described. In this reaction, -aminopyridinium salts and the Breslow intermediate, which is generated from NHC and aldehydes, are utilized to undergo a single-electron transfer process, forming a ketyl radical intermediate and amidyl radicals. Subsequent to the formation of the amidyl radical, it undergoes selective capture by alkenes, followed by radical cross-coupling to yield the desired β-amino ketones.

Polyurethane (PU), a segmented block copolymer with chemically resistant urethane linkages and tunable architecture, presents persistent biological recycling challenges. This study presents a Bacterial Laccase-Mediated System (BLMS) derived from for efficient degradation of polyester- and polyether-PU. Utilizing the laccase CotA and mediator 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), the BLMS demonstrated effective de polymerization of both commercial and self-synthesized PU foams, including polyester- and polyether-types.

Lipophilic yeasts of the genus are commensal fungi that constitute the normal skin microbiota but may become pathogenic. These fungi, especially , convert tryptophan into various alkaloid indoles such as malassezione, which may serve as virulence factors. To facilitate testing of malassezione as an aryl hydrocarbon receptor agonist and potential glucokinase activator, we developed a convenient synthetic route from commercially available indole-3-acetic acid.

Sodium-glucose Cotransporter 2 (SGLT-2) inhibitors are oral antidiabetic drugs that were developed for the treatment of patients with diabetes mellitus and are now also approved for treating chronic heart failure and chronic kidney disease. By inhibiting SGLT‑2 in the proximal renal tubule, urinary excretion of glucose is increased. Large randomized trials have demonstrated improved glycemic control, reduced cardiovascular events and lower mortality but also an increased risk of urogenital infections and dehydration.

[2,1]-Azaboranaphthalenes represent unique boron-nitrogen (BN) isosteres of naphthalenes, attracting interest for the development of molecules with enhanced therapeutic potency. The existing synthetic strategies are generally two-component reactions with harsh conditions. Here we report an organocatalysed three-component modular synthesis of ring-fused BN isosteres and BN-2,1-azaboranaphthalenes following ring expansion of unstrained cyclic ketones (n = 4-8) via Wolff-type rearrangement.

A ketogenic diet (KD) has shown promise as an adjunctive therapy for neurological and neuropsychiatric disorders, including bipolar disorder and major depressive disorder (MDD). We examined tolerance for a KD in young adults with MDD and assessed symptoms of depression and metabolic health. Students (n = 24) with a confirmed diagnosis of MDD at baseline receiving standard of care counseling and/or medication treatment were enrolled in a 10-12 week KD intervention that included partial provision of ketogenic-appropriate food items, frequent dietary counseling, and daily morning tracking of capillary R-beta-hydroxybutyrate (R-BHB).
