Objective: The present work is based on the above pyrazoline derivative form heterocyclic substituted chalcone. Methods: elemental analysis, IR, 1H and 13C NMR mass spectrum analyses were used to characterise structures of obtained compounds. Results: scheme-1 scheme-2 describe synthesis chalcone (thiophene-fluorenyl derivative) pyrazolines respectively. Chalcone has been synthesized from 2-Ace...

Chalcones, or 1,3–diaryl–2–propen–1–ones, one of the major classes of natural products and posses many useful properties like anticancer, antibacterial, antifungal, anti–inflammatory, antimalarial and anti–diabetic activity. We report in this communication the synthesis and anticancer study of a number of novel chalcone sulfonamides. Our results indicate that the synthesis of chalcone sulfonami...

Flavylium/Chalcone-based molecular switches comprise features such as pH-gated photochromism and fluorescence properties that make them attractive for many applications, ranging from stimuli-responsive materials to photopharmacology. However, in contrast other common photoswitches, the application of flavylium compounds these areas remains largely unexplored. Among possible reasons, this may be...

Heterocyclic compounds are an important class of in the field pharmaceutical and synthetic organic chemistry. The Schiff bases contain azomethine linkages which obtained by condensation aldehyde/ketone with amines. Among various types bases, chalcone-based play a vital role treatment ailments applications, can be synthesized using different chalcones as starting materials. These were techniques...

Chalcone synthase [naringenin-chalcone synthase; malonyl-CoA:4-coumaroyl-CoA malonyltransferase (cyclizing), E.C. 2.3.1.74], the key enzyme of flavonoid pathways that was believed to be soluble, has been localized on ribosome-bearing endoplasmic reticulum membranes in the epidermis of buckwheat (Fagopyrum esculentum M.) hypocotyls. Enzyme activity measurement and immunoblots of buckwheat hypoco...

The aim of this study was to investigate the in vivo toxicities of some novel synthetic chalcones. Chalcone and four chalcone analogues 1a-d were evaluated using zebrafish embryos following antibody staining to visualize their morphological changes and muscle fiber alignment. Results showed that embryos treated with 3'-hydroxychalcone (compound 1b) displayed a high percentage of muscle defects ...

A group of novel nitric oxide (NO) donating chalcone derivatives was prepared by binding various amino chalcones with different NO donating moieties including; nitrate ester, oximes and furoxans. Most of the prepared compounds showed significant anti-inflammatory activity using carrageenan-induced rat paw edema method compared with indomethacin. The prepared compounds exhibited more protection ...

The flavonoids are phenylpropanoid-derived metabolites that are ubiquitous in plants, playing many roles in growth and development. Recently, we observed that fruit rinds of yellow casaba muskmelons (Cucumis melo 'Inodorous Group') accumulate naringenin chalcone, a yellow flavonoid pigment. With RNA-sequencing analysis of bulked segregants representing the tails of a population segregating for ...
