Synthetic and Antimicrobial Studies of Some new Chalcones of 3-Bromo-4-(p-tolyl sulphonamido) acetophenone

open access: yesE-Journal of Chemistry, 2004
Eleven new chalcones have been sysnthesised by condensing 3-bromo-4-(p-tolyl sulphonamido) acetophenone with different aromatic aldehydes using the method or Rohrman et al. The antimicrobial activity of these chalcones has been tested by adopting “paper

Reaction of Chalcones with Cellular Thiols. The Effect of the 4-Substitution of Chalcones and Protonation State of the Thiols on the Addition Process. Diastereoselective Thiol Addition

open access: yesMolecules, 2021
Several biological effects of chalcones have been reported to be associated with their thiol reactivity. In vivo, the reactions can result in the formation of small-molecule or protein thiol adducts.

Synthesis, spectral correlation and insect antifeedant activities of some 2-benzimidazole chalcones

open access: yesJournal of Saudi Chemical Society, 2016
Some substituted styryl 2-benzimidazole ketones have been synthesised by fly-ash:H2SO4 catalysed aldol condensation of 2-benzimidazole methyl ketone and various substituted benzaldehydes in microwave oven. The yields of these chalcones are more than 70%.

Phthalocyanine-chalcone conjugates

open access: yesJournal of Porphyrins and Phthalocyanines, 2016
A phthalocyanine-chalcone conjugate was previously reported to retain the full photodynamic activity of the phthalocyanine and a slightly lowered antivascular effect of the chalcone. Assuming that it was due to an insufficient release of the chalcone, we described here several grafting modes applied to the preparation of phthalocyanine-chalcone ...

Identification and Functional Characterization of Fungal Chalcone Synthase and Chalcone Isomerase

open access: yesJournal of Natural Products, 2023
By mining fungal genomic information, a noncanonical iterative type I PKS fused with an N-terminal adenylation-thiolation didomain, which catalyzes the formation of naringenin chalcone, was found. Structural prediction and molecular docking analysis indicated that a C-terminal thioesterase domain was involved in the Claisen-type cyclization.

Green Synthesis, Characterization, Photophysical and Electrochemical Properties of Bis-chalcones

open access: yesInternational Journal of Electrochemical Science, 2014
Donor-acceptor conjugated dienes (bis-chalcones) were synthesized via an ultrasonic radiation, accomplished by the reaction between 3-acetyl-2,5-dimethylthiophene/1 (2,5-dimethyl-furan-3-yl)- ethanone and terephthalaldehyde.
