Studies of NMR Chemical Shifts of Chalcone Derivatives of Five-membered Monoheterocycles and Determination of Aromaticity Indices

A series of the chalcone derivatives of the five-membered monoheterocyclic compounds, (E)-1-aryl-3-heteroarylpropen-1-ones, were prepared by aldol condensation of the corresponding aldehydes of thiophene, pyrrole, and furan with m- and p-substituted acetophenones. Similar condensation of the acetyl compounds of the heterocycles with m- and p-substituted benzaldehydes gave another series of the chalcone derivatives, (E)-1-heteroaryl-3-arylpropen-1-ones. The 13C chemical shift values (δC) of the chalcone derivatives were determined in order to find if they correlated with the Hammett σ values. A good correlation, especially for the β-C for both series, was found for the 13C chemical shift values (δC) of the chalcone derivatives with the Hammett σ values. The chemical shift values of the β-C of the heterocyclic compounds were plotted against those of the benzene derivatives. The resulting slopes were found to be close to the values of the aromaticity indices.

Inhibitory potential of some chalcones on cathepsins B, H and L

Cathepsins, intracellular proteases, are known to be involved in a number of physiological processes such as degradation of extracellular proteins, prohormone processing, progressions of atherosclerosis etc. High levels of cathepsins have also been indica

Synthesis and biological evaluation of naphthalene, furan and pyrrole based chalcones as cytotoxic and antimicrobial agents

Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are collectively known as chalcones. These show antibacterial, antifungal, antitumour and antiinflammatory properties, and also are intermediates in the biosynthesis of flavonoids, substances widespread in plants with an array of biological activities. These biaryl propenones show potent toxicity to several cancer cell lines and interact with tubulin at its colchicine-binding site. Tubulin binding molecules interfere with the dynamic instability of microtubules and thereby disrupt microtubule inducing cell cycle arrest in the M phase, forming abnormal spindles and finally leading to apoptotic cell death. Basically Chalcones consists of C6-C3-C6 units but in the present study we report the reactions of 1-acetylnaphthalene, 2-acetylfuran and 2-acetylpyrrole with aldehydes, thus getting compounds akin to chalcones. 31 analogues have been synthesised and evaluated for cytotoxic potential against PC-3, OVCAR, IMR-32 and HEP-2. Compound 9 was found to be the most cytotoxic with inhibition ranging from 72 to 88% against the cell lines employed. The synthetics were also evaluated for antimicrobial activity and compound 25 was found to be the most potent. Springer Science+Business Media, LLC 2011.

Synthesis and In Vitro Antifungal Evaluation of 1,3,5-Trisubstituted-2-Pyrazoline Derivatives

Pyrazolines, the well-known five-membered nitrogen-containing heterocyclic compounds, have received considerable interests in the fields of medicinal and agricultural chemistry because of their broad spectrum of biological activities. To discover more pot

Effect of ring A and ring B substitution on the cytotoxic potential of pyrazole tethered chalcones

Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are collectively known as chalcones. The cytotoxic potential of chalcones which consists of C6-C 3-C6 units gets enhanced by the incorporation of pyrazole ring as proved by our earlier studies. Thus in the present work, pyrazoles of chalcones with ring A substituted by furan, naphthalene and variety of substituted phenyl rings has been prepared and evaluated for in vitro cytotoxic activity against PC-3, OVCAR, IMR-32, HEP-2 human cancer cell lines.

Synthesis and antibacterial activity of some heterocyclic chalcone analogues alone and in combination with antibiotics

A series of simple heterocyclic chalcone analogues have been synthesized by Claisen Schmidt condensation reactions between substituted benzaldehydes and heteroaryl methyl ketones and evaluated for their antibacterial activity. The structures of the synthe

A rational approach for the design and synthesis of 1-acetyl-3,5-diaryl-4, 5-dihydro(1H)pyrazoles as a new class of potential non-purine xanthine oxidase inhibitors

Xanthine oxidase is a complex molybdoflavoprotein that catalyses the hydroxylation of xanthine to uric acid. Fifty three analogues of 1-acetyl-3,5-diaryl-4,5-dihydro(1H)pyrazoles were rationally designed and synthesized and evaluated for in vitro xanthine
