Resolving a Nearly Two‐Centuries‐Old Mystery: On the Structural Chemistry and Physicochemical Properties of Compounds Associated With the Term Ammelide

open access: yesChemistry – A European Journal, Volume 32, Issue 9, 2 March 2026.
The crystal structure of ammelide, also known as melanuric acid, was solved almost 200 years after its discovery by Liebig. Moreover, three modifications of its 1:1 adduct with ammeline were structurally elucidated, consisting of layers with a honeycomb motif analogous to melamine cyanurate.

Some substitution reactions of aryl sulfides and aryl ethers with aliphatic amines in DMSO: the mechanism of base catalysis [PDF]

open access: yes, 1995
The reactions of several nitro-aromatic substrates with the aliphatic amines, n- butylamine, pyrrolidine and piperidine in DMSO have been studied. Reaction of the amines with trinitroaromatic compounds, such as ethyl thiopicrate, phenyl thiopicrate and ...

Neddylation Targets and Stabilizes NLRP3 to Augment Inflammasome‐Mediated Colitis and Mood Disorder

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
NLRP3 inflammasome contributes to colitis and mood disorder. This study demonstrates that neddylation targets NLRP3 at K287, which hinders its interaction with K48‐linked ubiquitination E3 Trim31 and thereby stabilizes it. Neddylation blockade in myeloid cells and microglia mitigates DSS‐induced colitis and psychological stress‐induced anxiety‐like ...

Some kinetic mechanistic and synthetic studies of the reactions of cyanide ions with aromatic nitro-compounds [PDF]

open access: yes, 1991
The reactions of cyanide ions with some benzene derivatives activated with electron-withdrawing groups have been studied in methanol, and in DMSO, and in mixtures of these solvents.

Kinetic and equilibrium studies of the reactions of some aromatic nitro compounds with metal alkoxides [PDF]

open access: yes, 1981
Kinetic and equilibrium measurements have been made for σ-adduct formation from propoxide ions in propan-1-ol with 1,3,5-trinitrobenzene and a series of l-propoxy-2,4-dinitro-6-x-benzenes ( x = NO(_2), Cl, CO(_2)Pr, H).The results are compared with those

Inflammation-induced Occludin Downregulation Limits Epithelial Apoptosis by Suppressing Caspase 3 Expression.

open access: yesGastroenterology, 2019
BACKGROUND & AIMS Epithelial tight junctions are compromised in patients with gastrointestinal disease. Occludin is a protein component of tight junctions; its removal from tight junctions or reduced expression results in barrier loss.
