Acaricides for eradication of the tick Amblyomma variegatum in the Caribbean [PDF]

open access: yes, 1993
Le succés d'une campagne d'éradication de la tique Amblyomma variegatum dans les Caraïbes impose l'utilisation d'acaricides efficaces, si possible rémanents, faciles d'emploi, ne necessitant pas le recours à de l'eau pour la préparation de liquides ...

The discovery of I-BRD9, a selective cell active chemical probe for bromodomain containing protein 9 inhibition [PDF]

open access: yes, 2016
Acetylation of histone lysine residues is one of the most well-studied post-translational modifications of chromatin, selectively recognized by bromodomain “reader” modules.

Amidines. II. Preparation of unsymmetrical N1,N2-disubstituted amidines.

open access: yesChemical and Pharmaceutical Bulletin, 1990
Unsymmetrical N1, N2-disubstituted amidines were prepared by conventional and newly developed methods. Reaction of N1-tosyl-N1, N2-diarylacetamidines and arylamines gave unsymmetrical acetamidines in the presence of basic catalysts, and N1-acyl-N1, N2-di(p-nitrophenyl)formamidines and arylamines gave unsymmetrical formamidines under neutral conditions.

Synthesis of novel 6-enaminopurines [PDF]

open access: yes, 2004
Two different approaches have been used for the synthesis of 6-enaminopurines 6 from 5-amino-4-cyanoformimidoyl imidazoles 1. In the first approach imidazoles 1 were reacted with ethoxymethylenemalononitrile or ethoxymethylenecyanoacetate under mild ...

Study on the Function and Mechanism of Neutrophil Extracellular Traps in Regulating Necroptosis Following Traumatic Brain Injury

open access: yesBrain and Behavior, Volume 16, Issue 3, March 2026.
TBI induces NETs formation, as evidenced by the upregulation of PAD4 and MPO. NETs activate the necroptosis pathway via phosphorylation of RIP1‐RIP3‐MLKL, thereby exacerbating secondary brain injury (neuronal death, BBB disruption, and neuroinflammation).

Synthesis and Characterization of 6-Carbamoyl-1,2-dihydropurines

open access: yesE-Journal of Chemistry, 2007
The aromatic amines react readily with (Z)-N-(2-amino-1,2-dicyanovinyl)formimidate (4) to give the amidines (5a-b), which cyclize in the presence of DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) to give the corresponding 2-(5-Amino-1-phenyl-1H-imidazol-4-yl ...

Selective Catalytic Oxidation of Benzyl Alcohol to Benzaldehyde With Alkyl Allyl Carbonates and Pd(II) Allyl‐Amidinate

open access: yesHelvetica Chimica Acta, Volume 109, Issue 3, March 2026.
A Pd(II) allyl‐amidinate complex catalyzes the selective oxidation of benzyl alcohols to aldehydes using allyl alkyl carbonates as tailored, mild oxidants. The carbonate reagent acts both as oxidant and in situ base, enabling chemoselective conversion and minimizing overoxidation under mild conditions.

Dysregulated proteolytic cascades in Netherton syndrome: from molecular pathology to preclinical drug testing

open access: yesThe Journal of Pathology, Volume 268, Issue 3, Page 249-262, March 2026.
Abstract Netherton syndrome (NS) is a rare, severe, and often life‐threatening disease for which current therapeutic approaches are limited and show variable effectiveness. NS is characterized by excessive epidermal desquamation that results in a highly defective epidermal barrier, constitutive skin inflammation, allergies, and hair abnormalities.
