Abstract:

Glycogen phosphorylase (GP) is a key enzyme in the glycogenolysis pathway. GP inhibitors are currently under investigation as a new liver-targeted approach to managing type 2 diabetes mellitus (DM). The aim of the present study was to evaluate the inhibitory activity of a panel of 52 structurally related chromone derivatives; namely, flavonoids, 2-styrylchromones, 2-styrylchromone-related derivatives [2-(4-arylbuta-1,3-dien-1-yl)chromones], and 4- and 5-styrylpyrazoles against GP, using in silico and in vitro microanalysis screening systems.

Objective: The objective of this study was to synthesize 7-amino-2-styrylchromone derivatives and evaluate their in vitro cytotoxic and antioxidant potential.Methods: 7-amino-2-styrylchromones were synthesized from 7-amino-2-methylchromone by condensing it with various substituted aromatic aldehydes. The cytotoxicity of the synthesized molecules was assessed against two cell lines, MCF-7 and HCT-116 by 3-(4,5-dimethyl thiazol-2-yl)-2,5- diphenyl tetrazolium bromide assay. Cell cycle analysis of the most potent molecule ASC-7 was carried out. The antioxidant studies were conducted by 2,2-diphen

The reaction proceeds by a tandem process involving 1,4- and 1,6-aza-conjugate additions of one amino group of ethane-1,2-diamine to the α,β-unsaturated (3-oxoprop-1-en-1-yl) and the α,β,γ,δ-diunsaturated (2-styrylchromone) carbonyl system of the precursor, followed by imine condensation of the remaining amino group

Abstract:

Recently, we identified 2-styrylchromones as a new class of antirhinovirus flavonoids with moderate activity against both rhinovirus groups A and B. In order to improve the antiviral effect of the first series of tested 2-styrylchromones, a hydroxy or methoxy group was introduced in position 3 of the chromone ring. Cytotoxicity and antiviral activity of the new synthesized compounds were evaluated in HeLa cell cultures infected with rhinoviruses 1B and 14, selected as representative serotypes for viral groups B and A of human rhinoviruses (HRVs), respectively. These antiviral results compared

Abstract:

Styrylchromones (SC) are a group of oxygen-containing heterocyclic compounds, which are characterized by the attachment of a styryl group to the chromone core. SC can be found in nature or can be chemically synthesized in the laboratory. As their presence in nature is scarce, the synthetic origin is the most common. Two types of SC are known: 2-styrylchromones and 3-styrylchromones. However, 2-styrylchromones are the most common, being more commonly found in nature and which chemical synthesis is more commonly described. A wide variety of SC has been described in the literature, with different

In this study, we initially focused on the structural modific- ations on B-ring while A-ring was free of substitution. The synthetic route of 2-styrylchromones was carried out in three steps that afforded 52a-q based on the abovementioned work.

Consequently, a large number of investigations have been carried out in order to find new, safer and potent antioxidant and anti-inflammatory drugs, and to elucidate their corresponding mechanisms of action. The evaluation of antioxidant vs antiradicalar and anti-inflammatory activity of phenolic compounds, either of natural or synthetic origin, is nowadays an important are

Among the tested agents, only 34 exhibited a moderate activity with an IC50 value of 28.9 μM against PC-3 cells which indicates the selectivity of PC-3 cells in response to 2-styrylchromones. In addition, 38 demonstrated the most antiproliferative effect with an IC50 value of 4.9 μM against HeLa cells. Together, these results suggest a potential structural optimization and pharmacological study of 2-styrylchromones
