Anticancer Active Heterocyclic Chalcones: Recent Developments.

Anti-Cancer Agents in Medicinal Chemistry, 2020
BACKGROUND Chalcones are structurally simple compounds that are easily accessible by synthetic methods. Heterocyclic chalcones have gained the interest among scientists due to their diverse biological activities. The anti-tumor activities of heterocyclic

Polarographic reduction of chalcones [PDF]

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1972
1. The influence of substituents on the polarographic reduction of chalcones and their vinylogs is exerted chiefly according to an inductive mechanism, and as a result of this decreased rapidly with increasing length of the chain of double bonds. 2.

Coupling–Isomerization Synthesis of Chalcones

Chemistry – A European Journal, 2006
AbstractThe Sonogashira coupling of electron‐deficient (hetero)aryl halides 1 and (hetero)aryl or alkenyl 1‐propargyl alcohols 2 does not terminate at the stage of the expected internal propargyl alcohols, but rather gives rise to the formation of α,β‐unsaturated ketones 3 with a variety of acceptor substituents.

Ferrocenyl chalcones versus organic chalcones: A comparative study of their nematocidal activity

Bioorganic & Medicinal Chemistry, 2011
A series of 30 organic chlacones and 33 ferrocenyl (Fc) chalcones were synthesized and characterized by melting point, elemental analysis, spectroscopy ((1)H NMR and FTIR) and, in two cases, by X-ray crystallography. The biological activity of each compound (10(-4)M in DMSO) against the model nematode Caenorhabditis elegans was examined in terms of ...

Photodimerization of heteroaryl chalcones: comparative antimicrobial activities of chalcones and their photoproducts

Medicinal Chemistry Research, 2011
The heterocyclic analogues of chalcones were synthesized by Claisen Schmidt reaction of (a) benzaldehyde with 2-acetylfurane, 2-acetylpyrrole and 2-acetylthiophene and (b) acetophenone with furfural, thiophene-2-carbaldehyde and pyrrole-2-carbaldehyde. The photolysis of class (a) and (b) chalcones under UV lamp gave different products.
