Synthesis and Anticonvulsant Activity of Some Quinazolin-4-(3H)-one Derivatives

open access: yesMolecules, 2008
A number of 3-substituted-2-(substituted-phenoxymethyl) quinazolin-4(3H)-one derivatives 4a,b, 5a-c, 6, 7a-f, 8a-e and 9a,b have been synthesized. Their structures have been elucidated on the basis of elemental analyses and spectroscopic studies (IR, 1H ...

Synthesis, biological evaluation and docking analysis of substituted piperidines and (2-methoxyphenyl)piperazines [PDF]

open access: yesJournal of the Serbian Chemical Society, 2016
A series of sixteen novel substituted piperidines and (2-methoxyphenyl)piperazines were synthesized, starting from the key intermediates 1-(2-methoxyphenyl)-4-(piperidin-4-yl)piperazine and 1-(2-methoxyphenyl)-4-(piperidin-4-ylmethyl)piperazine.

Bioinspired Polypeptide Dendrimer‐Modified Thin‐Film Composite Membranes for Selective Lithium‐Magnesium Separation with DFT Insights

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated a biomimetic dendrimer‐modified thin‐film nanocomposite membrane with a coordination‐assisted ion‐selective interface. pH‐responsive polypeptide sites preferentially bind Mg2+ and promote Li+ permeation, as predicted by density functional theory calculations of metal‐ligand interactions.

Microfluidic Platform for Multiparametric Profiling of Fibrin Permeability, Fibrinolysis, and Cell Invasion

open access: yesAdvanced Functional Materials, EarlyView.
This paper introduces a single‐channel H‐junction microfluidic assay that profiles fibrin's evolving function in repair and thrombosis by measuring, in one ∼3 µL gel, permeability, fibrinolysis kinetics, fibroblast invasion, and clot extension in real time.

Aminal‐linked Covalent Organic Frameworks for Light Energy Upconversion

open access: yesAngewandte Chemie, EarlyView.
Aminal‐linked covalent organic frameworks incorporating anthracene units are introduced as solid‐state platforms for triplet–triplet annihilation upconversion. The crystalline materials retain chromophore electronic properties and exhibit fluorescence quantum yields of up to 40%.

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

Synthesis of novel antibacterial and antifungal dithiocarbamate-containing piperazine derivatives via re-engineering multicomponent approach

open access: yesHeliyon, 2022
A metal-free multicomponent synthetic route for the diverse preparation of dithiocarbamate-containing piperazine derivatives was developed through the C–N bond cleavage of DABCO ring.

A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

open access: yesAdvanced Healthcare Materials, EarlyView.
Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.

Semi‐Reduction of Allenes to Access Deuterated Allylic Isotopomers, Isotopologs and Enantioisotopomers

open access: yesAngewandte Chemie, EarlyView.
Modular and Precise Deuteration: The synthesis of molecules precisely deuterated at allylic, vinylic or both positions remains a challenging task. This work discloses a modular semi‐reductive deuteration that enables the synthesis of various isotopologs including precisely labeled d1‐, d2‐, d3‐, d5‐, and d7‐products.
