A Synthetic Route to Quaternary Pyridinium Salt-Functionalized Silsesquioxanes

International Journal of Polymer Science, 2012
A synthetic route to potentially biocidal silsesquioxanes functionalized by quaternary pyridinium functionalities has been developed. N-Alkylation reactions of the precursor compounds 4-(2-(trimethoxysilyl)ethyl)-pyridine (5) and 4-(2-trichloro ...

In Vitro Evaluation of Neutral Aryloximes as Reactivators for Electrophorus eel Acetylcholinesterase Inhibited by Paraoxon

Biomolecules, 2019
Casualties caused by organophosphorus pesticides are a burden for health systems in developing and poor countries. Such compounds are potent acetylcholinesterase irreversible inhibitors, and share the toxic profile with nerve agents.

L-Aspartic acid pyridinium salts: In silico, synthesis and adjuvant vs antibiotic antibacterial evaluation

Results in Chemistry
In the present study, a new series of chiral L-aspartic acid pyridinium salts have been designed, guided by molecular docking as antiemetics via TrySR or DNA GryB inhibitors, as well as an adjuvant to chloramphenicol via CAT-III inhibitor to continue ...

Two-Dimensional, Pyrazine-Based Nonlinear Optical Chromophores with Ruthenium(II) Ammine Electron Donors [PDF]

, 2010
Six new nonlinear optical (NLO) chromophores with pyrazinyl-pyridinium electron acceptors have been synthesized by complexing a known pro-ligand with electron donating {Ru^(II)(NH_3)_5}^(2+) or trans-{Ru^(II)(NH_3)_4(py)}^(2+) (py = pyridine) centers ...

Self‐Assembled (Aza)BODIPY Dyes for Biomedical in Vivo Imaging

Angewandte Chemie International Edition, EarlyView.
This minireview classifies (aza)BODIPY dyes according to their molecular stacking modes and aggregate types (H‐, oblique‐, or J‐type) in aqueous media, correlating these features with their multimodal imaging performance. By linking molecular design, exciton coupling, and pathway‐dependent assembly, we provide a framework for engineering next ...

Synthesis of Pyridinium Moiety Containing Triazolyl Purines

Molbank
Pyridinium salts of 2-piperidinyl-6-triazolylpurine derivatives were obtained by the introduction of pyridinium moieties into the propane-1,3-diol fragment at the N(9) position of purine to enhance the solubility of 2-amino-6-triazolylpurine derivatives ...

Design, synthesis, in silico studies and in vitro evaluation of isatin-pyridine oximes hybrids as novel acetylcholinesterase reactivators

Journal of Enzyme Inhibition and Medicinal Chemistry, 2021
Organophosphorus poisoning caused by some pesticides and nerve agents is a life-threating condition that must be swiftly addressed to avoid casualties. Despite the availability of medical countermeasures, the clinically available compounds lack a broad ...
