Systemic Toxicity of L‐Mimosine in Rabbits: A Non‐Rodent Model for Safety Assessment

Journal of Applied Toxicology, Volume 46, Issue 2, Page 639-651, February 2026.
ABSTRACT L‐mimosine is a non‐protein amino acid primarily found in the Mimosoideae subfamily, with high concentrations in Leucaena leucocephala and Mimosa pudica. These plants are widely used in both human and animal nutrition, as well as in phytotherapeutic applications. While the toxic effects of L‐mimosine have been extensively studied in ruminants,

New paradigms for understanding and step changes in treating active and chronic, persistent apicomplexan infections [PDF]

, 2016
Toxoplasma gondii, the most common parasitic infection of human brain and eye, persists across lifetimes, can progressively damage sight, and is currently incurable. New, curative medicines are needed urgently.

A novel approach to target skin photodamage: Topical application of salt inducible kinase inhibitors

International Journal of Cosmetic Science, Volume 48, Issue 1, Page 1-15, February 2026.
UV‐induced photodamage leads to increased DNA damage and elevated MMP levels, which degrade collagen and contribute to wrinkle formation. SLT‐001 and SLT‐008, novel cosmetic ingredients that target salt‐inducible kinase, help reverse this effect by enhancing DNA repair, reducing MMP expression and decreasing erythema, thereby mitigating photodamage ...

Nickel‐Catalyzed cine‐Substitution Toward Carbonyl Dance

Chemistry – An Asian Journal, Volume 21, Issue 1, January 2026.
A nickel‐catalyzed cine‐substitution enables a 1,2‐carbonyl translocation (“carbonyl dance”) at tetralone derivatives under mild conditions. This transformation proceeds through enolization and selective amination, followed by hydrolysis, to afford β‐tetralones bearing migrated carbonyl groups.

General Method for the Preparation of Substituted 2-Amino-4H,5H-pyrano[4,3-b]pyran-5-ones and 2-Amino-4H-pyrano[3,2-c]pyridine-5-ones

Molecules, 2000
Reaction of 4-hydroxy-6-methyl-2-pyrone (1a) as well as 4-hydroxy-6-methyl-2(1H)-pyridones (1b-d) with arylmethylene malononitriles or arylmethylene methyl cyanoacetates (2a-h) leads to the formation of the very stable 5,6-fused bicyclic 2-amino-4Hpyran ...

Asymmetric aerobic oxidative NHC-catalysed synthesis of dihydropyranones utilising a system of electron transfer mediators [PDF]

, 2016
In the context of green chemistry, the replacement of high molecular weight stoichiometric oxidants with O2 is most desirable but difficult. Here, we report the asymmetric aerobic oxidative synthesis of dihydropyranones.

Shedding Light on the Precatalytic Mixture of Pd(OAc)2 and Cooperating Bipyridone Ligands for the C─H Functionalization of Arenes

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
The reactions of the common palladium precursors Pd(OAc)2 and PdCl2 and cooperating bipyridone ligands leads to well defined complexes which are general precatalysts for the direct C─H arylation of arenes, more active than Pd(OAc)2/ligand mixtures in nonpolar solvents.
