Synthesis of certain nitropyridine derivatives bearing 2-thiazolyl hydrazines with expected monoamine oxidase inhibitory activity [PDF]

open access: yesBulletin of Pharmaceutical Sciences. Assiut University, 1999
Two series of nitropyridine derivs. bearing 2-​thiazolyl hydrazines were synthesized and evaluated for their monoamine oxidase (MAO) inhibitory activity by in vitro tests to assay their effect on rat liver mitochondria by a kynuramine fluorimetric assay.

Chemical Strategies for Multistimuli Responsive Dynamic Covalent Materials in Regenerative Medicine

open access: yesAdvanced Healthcare Materials, EarlyView.
Multistimuli responsive dynamic covalent materials integrate reversible chemistry with the complex chemical, mechanical, and biochemical cues of regenerative environments. This review highlights chemical strategies based on orthogonal dynamic bonds, multicomponent networks, and hierarchical architectures to regulate mechanics, degradation, and ...

Dynamic Electrophoretic Assembly Coupled With Water‐Splitting‐Induced pH Control Enables Precision Ion Sieving Membranes

open access: yesAdvanced Materials, EarlyView.
A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering

Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

open access: yesAdvanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

Characterization of NAT2 Using Long-Read Sequencing: Allele, Diplotype, and Phenotype Call Accuracy Compared to Other Testing Strategies. [PDF]

open access: yesClin Pharmacol Ther
The NAT2 pharmacogene is essential in drug metabolism, particularly for aromatic amines and hydrazines. Genetic variations in NAT2 categorize individuals as rapid, intermediate, or poor metabolizers based on their acetylation capacity to inform dosing guidelines.
