A new series of copolyester chalcone derivatives were synthesised from 1, 3-bis (4-hydroxy-3methoxyphenyl) propenone (BHMPP) and 1(3, 5-dihydroxyphenyl)-3-(4-methoxyphenyl) propenone (DHPMPP) with adipoyl, suberoyl, azeloyl and sebacoyl chlorides by phase transfer catalysed polycondensation method. The microstructure of the repeating unit was confirmed by IR, 1 H and 13 C NMR. These copolyester...

Cancer is an inevitable matter of concern in the medicinal chemistry era. Chalcone is the well exploited scaffold in the anticancer domain. The molecular mechanism of chalcone at cellular level was explored in past decades. This mini review provides the most recent updates on anticancer potential of chalcones.

Expression of the alcohol dehydrogenase (Adh) and ribulose-1,5-bisphosphate carboxylase small subunit (RbcS) genes of higher plants is cell-type-specific and environmentally inducible. However, the tissues in which these two genes are expressed, their modes of induction, and their protein functions are quite distinct. Adh is expressed in non-green tissue, induced by anaerobiosis, and repressed ...

Background Dermatophytes are adapted to grow in keratinized tissues such as skin, nail and hair. Trichophyton rubrum is the most frequent cause of dermatophytosis in Brazil and in the world [1]. Despite its incidence there are only a limited number of antifungal drugs available for clinical use and some drugs are highly toxic to humans. In this regard, chalcones and alkaloids are phytochemical ...

The aim of this study was to synthesize chalcone-polyamine conjugates in order enhance bioavailability and selectivity chalcone core towards cancer cells, using polyamine-based vectors. Indeed, it is well-known that polyamine transport system upregulated tumor cells. 3′,4,4′,5′-tetramethoxychalcone selected as parent since found be an efficient anti-proliferative agent on various A series five ...

A number of novel heterocyclic chalcone derivatives can be synthesized by thermal and microwave tools. Treatment of 4-(4-Acetylamino- and/or 4-bromo-phenyl)-4-oxobut-2-enoic acids with hydrogen peroxide in alkaline medium were afforded oxirane derivatives 2. Reaction of the epoxide 2 with 2-amino-5-aryl-1,3,4-thiadiazole derivatives yielded chalcone of imidazo[2,1-b]thiadiazole derivative 4 via...

Purpose: The study was designed to investigate the effects of a novel spironolactone chalcone in the prevention of peritoneal fibrosis. Methods: Wistar rats (n = 30) were randomly assigned to 3 groups: bacteria (B), spironolactone amide treatment (S), and control (C) groups. C group received only dextran beads while S and B groups were given bacteria and dextran beads intraperitoneally, but spi...

The purpose of this paper is to investigate the inhibition effect of some Chalcone derivatives on the corrosion behavior of aluminum in 1 M phosphoric acid solutions with and without Chalcone derivatives and to investigate the influence of halide additives namely: KCl, KBr and KI on the inhibition efficiency of aluminum. For this purpose, polarization (DC) and weight loss measurements were used...

An effective method has been developed for the preparation of novel chiral chalcone derivatives under mild conditions from the easily accessible starting materials nitromethane and chalcone derivatives 2. The corresponding products were obtained in moderate yields with excellent enantioselectivities (up to 99%).
