Decoding Interfacial Polymerization Through Steady Amine Delivery and Real-Time QCM-D Monitoring. [PDF]

open access: yesAdv Sci (Weinh)
We combine steady amine delivery with in situ quartz crystal microbalance with dissipation to track interfacial polymerization in real time. The platform resolves three kinetic regimes: pre‐gelation oligomerization, post‐gelation aggregation and network growth, and diffusion‐limited film evolution.

A Review on 1,2,3 - Triazole & Piperazine Derivatives with Various Biological Activities [PDF]

open access: yes, 2023
The largest family of organic molecules in organic chemistry are heterocyclic compounds. A heterocyclic compound is created when an oxygen, nitrogen, sulphur, or atom of a similar element is included in place of a carbon atom. Heterocyclic compounds play

Synthesis and spectroscopic investigation of substituted piperazine-2,5-dione derivatives [PDF]

open access: yes, 2023
The piperazine-2,5-dione moiety is a useful scaffold for functionalisation to generate bioactive molecules. Synthetic methods for accessing substituted piperazine-2,5-diones involve cyclising dipeptides or building from the already established core ...

Piperazine-Based Mitochondria-Immobilized pH Fluorescent Probe for Imaging Endogenous ONOO– and Real-Time Tracking of Mitophagy

open access: yes, 2022
ONOO– is mainly produced in mitochondria, and dysfunctional and damaged mitochondria are degraded in lysosomes through autophagy, so it is important to synthesize a single probe for dual detection of ONOO– and mitophagy.

Syntheses and crystal structures of 4-(4-nitrophenyl)piperazin-1-ium benzoate monohydrate and 4-(4-nitrophenyl)piperazin-1-ium 2-carboxy-4,6-dinitrophenolate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2022
Crystal structures are reported for two molecular salts containing the 4-(4-nitrophenyl)piperazin-1-ium cation. Co-crystallization from methanol/ethyl acetate solution of N-(4-nitrophenyl)piperazine with benzoic acid gives the benzoate salt, which ...

Design, Synthesis and Molecular Docking Studies of Some Novel Hydrazone Derivatives Based on Trimetazidine as Selective and Potent AChE Inhibitors. [PDF]

open access: yesDrug Dev Res
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative disease, and cholinergic dysfunction is considered one of the fundamental pathological factors of this disease. Guided by the clinically used acetylcholinesterase (AChE) inhibitor donepezil, we explored trimetazidine dihydrochloride as an accessible starting scaffold to generate ...
