Potent and highly selective dual‐targeting monoamine oxidase‐B inhibitors: Fluorinated chalcones of morpholine versus imidazole

Archiv der Pharmazie, 2019
Two series of fluorinated chalcones containing morpholine and imidazole‐based compounds (f1–f8) were synthesized and evaluated for recombinant human monoamine oxidase (MAO)‐A and ‐B as well as acetylcholinesterase inhibitory activities.

Expression of chalcone synthase and chalcone isomerase proteins in Arabidopsis seedlings.

Plant molecular biology, 1997
Antibodies have been developed against the first two enzymes of flavonoid biosynthesis in Arabidopsis thaliana. Chalcone synthase (CHS) and chalcone isomerase (CHI) were overexpressed and purified from Escherichia coli as fusion proteins with glutathione S-transferase from Schistosoma japonicum.

The retroaldol reaction of chalcone

Canadian Journal of Chemistry, 1983
All four rate constants required to describe the hydration and aldolization/dealdolization reactions of chalcone (1,3-diphenyl-2-propen-1-one) have been determined in aqueous sodium hydroxide solutions. Kinetics were studied starting with chalcone, with its hydrate, 1,3-diphenyl-3-hydroxy-1-propanone, and with benzaldehyde in the presence of excess ...

Polymorphism and conformerism in chalcones

CrystEngComm, 2016
Herein two solid state phenomena have been observed in two chalcones. Firstly, polymorphism has been found in (E)-1-(2-aminophenyl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one (1). This compound crystallizes with only one conformer rather than three in the known reported structure. In the polymorphs, the conformation of the phenyl ring bonded to carbonyl

Perspective design of chalcones for the management of CNS disorders: A mini-review.

CNS and Neurological Disorders - Drug Targets, 2019
The development of chalcone based compounds for CNS disorders have been explored by many research groups. Chalcones are being considered as a potent organic scaffold with wide spread applications in the field of drug discovery and medicinal chemistry ...

The reaction of chalcone with phosphonates

Tetrahedron, 1971
Abstract Chalcone reacts with the anions of triethyl phosphonoacetate (I) and diethyl benzylphosphonate (IV)—depending on the operating conditions—either in a Michael or a Wittig-Horner reaction.

Inhibiting Firefly Bioluminescence by Chalcones

Analytical Chemistry, 2017
Chalcone refers to an aromatic ketone and an enone that constitutes the central core for various important biological compounds in drug discovery. Moreover, the firefly luciferase (Fluc) as the bioluminescent reporter has been widely used in life science research and high-throughput screening (HTS).

The behavior of some chalcones on acetylcholinesterase and carbonic anhydrase activity

Drug and chemical toxicology (New York, N.Y. 1978), 2018
Carbonic anhydrase (CA) has a key role in respiration, carbon dioxide and bicarbonate transport. Acetylcholinesterase (AChE) is a serine hydrolase and mostly abundant at neuromuscular junctions and cholinergic brain synapses.

Photochemical Behavior of Chalcone and the Photo-Alignment of Liquid Crystal with Chalcone Derivatives

Molecular Crystals and Liquid Crystals, 2002
The photoisomerization behavior of benzylidene-acetophenones known as chalcones, was studied. We synthesized the chalcone derivatives that have ether groups at 4 and 4′ positions. Due to the electron donating ability of the ether oxygen, the bond order of the single bond between two phenyl ring of the chalcone strengthened, which eventually increased ...
