Two Zinc(II) Complexes with Similar Hydrazone Ligands: Syntheses, Crystal Structures and Antibacterial Activities

Acta Chimica Slovenica, 2020
A pair of new mononuclear zinc(II) complexes with hydrazone ligands 4-methoxybenzoic acid (1-pyridin-2-ylmethylidene)hydrazide (HLa) and benzoic acid (1-pyridin-2-ylethylidene)hydrazide (HLb) were prepared. They are [Zn(La)2] (1) and [Zn(Lb)2] (2).

Catalysis of Hydrazone and Oxime Peptide Ligation by Arginine

, 2020
Hydrazone and oxime peptide ligations are catalyzed by arginine. The catalysis is assisted intramolecularly by the side-chain guanidinium group. Hydrazone ligation in the presence of arginine proceeds efficiently in phosphate buffer at neutral pH but is ...

RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease

Hepatology, EarlyView., 2022
RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease. Abstract Background and Aims Receptor‐interacting protein kinase 3 (RIPK3) mediates NAFLD progression, but its metabolic function is unclear. Here, we aimed to investigate the role of RIPK3 in modulating mitochondria function, coupled with lipid droplet (LD)

Metallaphotocatalytic Amination of Aryl Chlorides Enabled by Highly Crystalline Acetylene-Based Hydrazone-linked Covalent Organic Frameworks

, 2023
Amination of aryl chlorides by metallaphotocatalysis is highly desired but remained practically challenging. Meanwhile, relying on soluble noble-metal photocatalysts suffers from resource scarcity and structural instability which limit their practical ...

Synthetic and Biocidal Studies of Zn-Hydrazone Complexes

, 2022
A series of hydrazone derivatives were synthesized through multi-step reactions. The 2-(2-oxo-1,2,3,4-tetrahydroquinoline-7-yloxy)acetohydrazide was prepared from 7-hydroxy-3,4-dihydroquinolin-2(1H)-one as starting material. Then the condensation of 2-(2-
