Comprehensive Study of Chalcone Derivatives

International Journal of Newgen Research in Pharmacy & Healthcare, 2023
Chalcones are flavonoid molecules that exist naturally and are essentially plant substances. These are the chemical compounds that have demonstrated a variety of intriguing biological actions with therapeutic potential against a variety of ailments. Anthranilic acid and orthophenylene diamine combine to produce benzimidazole.

Structural study on chalcone derivatives

Synthetic Metals, 1994
Abstract Crystal structures of several SHG-active chalcone derivatives were determined by X-ray analysis. The phase-matching direction of a 1-(3-thienyl)-3-(4-chlorophenyl)-2-propen-1-one crystal is discussed by relating to its molecular packing in the crystal.

Anticancer activities of novel chalcone and bis-chalcone derivatives

Bioorganic & Medicinal Chemistry, 2006
A series of novel chalcones and bis-chalcones containing boronic acid moieties has been synthesized and evaluated for antitumor activity against the human breast cancer MDA-MB-231 (estrogen receptor-negative) and MCF7 (estrogen receptor-positive) cell lines and against two normal breast epithelial cell lines, MCF-10A and MCF-12A.

Stereoselectivity of chalcone isomerase with chalcone derivatives: a computational study

Journal of Molecular Modeling, 2013
Chalcone isomerase (CHI) catalyzes the intramolecular cyclization of chalcones into flavonoids. The activity of CHI is essential for the biosynthesis of flavonoids precursors of floral pigments and phenylpropanoid plant defense compounds. In the present study, we explored the detailed binding structures and binding free energies for two different ...

Chalcone derivatives from Polygonum lapathifolium

Phytochemistry, 1988
Abstract The investigation of Polygonum lapathifolium L. afforded, in addition to 2′-hydroxy-4′,6′-dimethoxychalcone, three new derivatives. The structures were elucidated by high field 1 H NMR techniques.

OESTROGENIC AND ANTIFERTILITY EFFECTS OF CHALCONE DERIVATIVES

Acta Endocrinologica, 1973
ABSTRACT Three newly synthesized non-steroidal derivatives of chalcone (benzalacetophenone), viz., 2′-chloro-4:4′-difluorochalcone (CH-4), 2′-chloro-3:4-methylenedioxy-4′-fluorochalcone (CH-6) and 2′-hydroxy-3:4-methylenedioxy-4′-fluorochalcone (CH-8) were evaluated for their oestrogenicity in the mouse and were found to possess a statistically

Flavanone and Chalcone Derivatives from Cryptocarya kurzii

Journal of Natural Products, 1993
Four complex flavanones, kurziflavolactones A [2], B [3], C [4], and D [5] and a complex chalcone 6 with an unprecedented carbon side chain on the flavanone or chalcone A ring have been isolated from a Malaysian plant, Cryptocarya kurzii (Lauraceae).

Phenylsulfonyl derivatives of chalcones derived from 5-nitrofuran

Collection of Czechoslovak Chemical Communications, 1983
1-(5-Nitro-2-furoyl)-1-phenylsulfonyl-2-(4-X-phenyl)ethylenes II were synthesized by condensation of phenyl-2-(5-nitro-2-furyl)-2-oxoethyl sulfone (I) with 4-substituted benzaldehydes (X = H, CH3, CH3O, N(CH3)2, F, Cl, NO2, CN) in tetrahydrofuran or dioxane under catalysis of titanium-IV chloride and pyridine. As evidenced by spectral data (1H NMR, IR,

Antifungal action of the oxathiolone‐fused chalcone derivative

Mycoses, 2011
SummaryAMG‐148, an oxathiolone‐fused chalcone derivative, exhibited in vitro antifungal activity against several strains of human pathogenic yeast, with minimum inhibitory concentration values within the range of 1–16 μg ml−1 and a fungicidal effect was observed at higher concentrations.
