Design, synthesis and biological evaluation of 1-Phenyl-2-(phenylamino) Ethanone Derivatives as Novel MCR-1 Inhibitors

Polymyxins are considered to be the last-line antibiotics that are used to treat infections caused by multidrug-resistant (MDR) gram-negative bacteria; however, the plasmid-mediated transferable colistin resistance gene (mcr-1) has rendered polymyxins ine

1-phenyl-2-phenylaminoethyl ketone derivative and medical application

The invention belongs to the field of pharmaceutical chemicals, and relates to a micromolecular inhibitor of polymyxin drug-resistant protein MCR-1 and application thereof. The invention relates to acompound shown as a formula I, a pharmaceutically accept

Syntheses, Cholinesterases Inhibition, and Molecular Docking Studies of Pyrido[2,3-b]pyrazine Derivatives

Cholinesterases, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), have a role in cholinergic deficit which evidently leads to Alzheimer's disease (AD). Inhibition of cholinesterases with small molecules is an attractive strategy in AD therapy. This study demonstrates synthesis of pyrido[2,3-b]pyrazines (6a-6q) series, their inhibitory activities against both cholinesterases, AChE and BChE, and molecular docking studies. The bioactivities data of pyrido[2,3-b]pyrazines showed 3-(3′-nitrophenyl)pyrido[2,3-b]pyrazine 6n a potent dual inhibitor among the series against both AChE and BChE with IC50 values of 0.466 ± 0.121 and 1.89 ± 0.05 μm, respectively. The analogues 3-(3′-methylphenyl)pyrido[2,3-b]pyrazine 6c and 3-(3′-fluorophenyl)pyrido[2,3-b]pyrazine 6f were found to be selective inhibition for BChE with IC50 values of 0.583 ± 0.052 μm and AChE with IC50 value of 0.899 ± 0.10 μm, respectively. Molecular docking studies of the active compounds suggested the putative binding modes with cholinesterases. The potent compounds among the series could potentially serves as good leads for the development of new cholinesterase inhibitors. A series of pyrido[2,3-b]pyrazine (6a-6q) derivatives has been synthesized and evaluated for inhibitory activities against cholinesterases; acetylcholinesterase, and butyrylcholinesterase. Molecular docking of active compounds was also performed to suggest the putative binding modes with cholinesterases.

PYRIDOPYRAZINES AS ANTICANCER AGENTS

The present invention relates to pyridopyrazine derivatives and solvates, hydrates and pharmaceutically acceptable salts thereof, the use of them in the prevention and/or the treatment of cancer diseases, as well as pharmaceutical compositions containing at least one of them as pharmaceutically active agent(s) together with pharmaceutically acceptable carrier, excipient and/or diluents, especially for the prevention and/or treatment of cancer diseases.˙

Preparation of pyrido [2,3-b] pyrazine ring system via regioselective condensation reaction

The pyrido[2,3-b]pyrazine core structure can be found in several molecules that express biological activity. We have previously published a series of these compounds that showed erlotinib-resistant tumor inhibitor potential. The common way of their synthe

A convenient synthesis of novel 2,8-disubstituted pyrido[3,4-b]pyrazines possessing biological activity

A regioselective synthetic route to 2,8-disubstituted pyrido[3,4-b] pyrazines, by initial condensation reaction between suitable diaminopyridines and α-keto aldehydes equivalents, has been developed. Focusing on the functionalization on C-8, 2-aryl-8-bromo- and 8-amino-2-arylpyrido[3,4-b] pyrazines have been synthesized. Anilines, amides, and ureas have been introduced at the 8-position from key intermediates. 2,8-Disubstituted pyrido[3,4-b]pyrazines thus prepared were found to be of biological interest.
