Ammonium metavanadate (NH4VO3): a highly efficient and eco-friendly catalyst for one-pot synthesis of pyridines and 1,4-dihydropyridines [PDF]

open access: yesScientific Reports, 2022
In this study, we reported the ammonium metavanadate (NH4VO3) as an efficient, cost-effective, and mild catalyst for the synthesis of substituted pyridines via a one-pot pseudo four-component reaction.

Acyl-1,4-Dihydropyridines: Universal Acylation Reagents for Organic Synthesis [PDF]

open access: yesMolecules
Acyl-1,4-dihydropyridines have recently emerged as universal acylation reagents. These easy-to-make and bench-stable NADH biomimetics play the dual role of single-electron reductants and sources of acyl radicals.

Antileishmanial and Antitoxoplasmal Activities of 1,4-Dihydropyridines [PDF]

open access: yesACS Omega
Abstract: We have synthesized 24 1,4-dihydropyridine compounds (1,4-DHPs) with different substituents at the aromatic ring by microwave-assisted one-pot Hantzsch multicomponent reac-tion and evaluated their in vitro activities against Toxoplasma gondii and Leishmania major.

Dually Acting Nonclassical 1,4-Dihydropyridines Promote the Anti-Tuberculosis (Tb) Activities of Clofazimine [PDF]

open access: yesMolecules, 2019
The number of effective antituberculotic drugs is strongly limited to four first-line drugs in standard therapy. In case of resistances second-line antibiotics are used with a poor efficacy and tolerability.

Direct Aminolysis of Ethoxycarbonylmethyl 1,4-Dihydropyridine-3-carboxylates [PDF]

open access: yesMolecules, 2015
The ethoxycarbonylmethyl esters of 1,4-dihydropyridines were directly converted into carbamoylmethyl esters in the presence of 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) in good to excellent yields under mild conditions.

Anticancer Activity of 4-Aryl-1,4-Dihydropyridines

open access: yesFuture Pharmacology
We have synthesized 22 symmetric and asymmetric 4-aryl-1,4-dihydropyridines (1,4-DHPs) by a “green” microwave-assisted one-pot multicomponent Hantzsch reaction and evaluated their cytotoxicity to three human cancer cell lines regarding U-251MG (human ...
