Synthetic and Mechanistic Studies in the Chromone and Isoquinoline Series. Author: Frost, J. A new chromone-appended Cu(ii) drug entity (1) was designed and synthesized as a potential anticancer chemotherapeutic agent.

The structural elucidation was carried out thoroughly by elemental analysis, FT-IR, EPR, ESI-MS and single crystal X-ray crystallography. Complex 1 resulted from the in situ methoxyla. DNA-binding properties studies and spectra of a novel fluorescent Zn(II) complex with a new chromone derivative.

In vitro studies to fourteen previously synthesized chromone-tetrazoles and four novel fluorine-containing analogs were conducted against pathogenic protozoan (Entamoeba histolytica), pathogenic bacteria (Pseudomonas aeruginosa, and Staphylococcus aureus), and human fungal pathogens (Sporothrix schenckii, Candida albicans, and Candida tropicalis), which have Cited by: 8.

Chromone synthetic methodology has also been explored for the synthesis of the marine natural product, Rietone A.

Naturally occurring chromones Only about 55 chromones occur naturally, with the majorIty containhlg an alkoxy or hydroxyl group. Several chromone derivatives carry hydroxyl groups at C-5 and C-7 and a. In the present study, we show that a novel chromone derivative, DCO-6, significantly reduced lipopolysaccharide (LPS)-induced production of nitric oxide, IL.

Synthetic methods often lead to a mixture of chromones and coumarins which can be separated by a chemical method. To a mixture of chromone and coumarin was added a solution of sodium ethoxide in ethanol, whereby the 2- and 4-pyranone rings were opened to give phenolic diketone and carboxylic acid, respectively.

Rohitukine is a chromone alkaloid with antiinflammatory, antifertility, anticancer, and immunomodulatory properties. I was discovered in Amoora rohituka and later reported in Dysoxylum binectariferum, both belonging to the Meliaceae family [].Based on this scaffold two synthetic flavoalkaloids have been developed, flavopiridol (Fig.

Organizations adopt structures and procedures in search of legitimacy and institutionalization (Riebero & Scapens,p.

96). Structures manifest themselves in centralized (mechanistic. A series of 7-hydroxy, 8-hydroxy and 7,8-dihydroxy synthetic chromone derivatives was evaluated for their DPPH free radical scavenging activities.

A training set of 30 synthetic chromone derivatives was subject to three-dimensional quantitative structure-activity relationship (3D-QSAR) studies using molecular field analysis (MFA). The substitutional requirements for.

Chromones are introduced into a double-tandem [4π+2π][2π+2π][4π+2π][2π+2π] synthetic sequence, culminating in photoprotolytic oxametathesis, which leads to an expeditious growth of molecular complexity over a few experimentally simple steps. The overall reaction can potentially be utilized in diversity-oriented synthesis, as it allows for three or more diversity inputs.

Abstract. In the present study, we prepared a series of 21 chromone carboxamide derivatives bearing diverse amide side chains. Their potency to inhibit the proliferation of breast (MCF-7), ovarian (OVCAR and IGROV), and colon (HCT) cancer cell lines, was evaluated in vitro using the MTT assay.

Methods: In this study, we test a novel series of synthetic chromone and coumarin derivatives (1–9) for cytotoxic activity against a panel of tumor cell lines (MCF-7, A, HepG2, HTC, B16 and Caco-2) opposed to non-tumor cells (HEKt).

Electrical impedance spectroscopy was used to monitor cell viability in real time. Chromone and coumarin derivatives exhibit a wide spectrum of biological activity, including spasmolytic, antiarrhythmic, cardiothonic, antiviral, and anticancer properties. Phosphorus-containing chromone and coumarin derivatives form a novel group of compounds, possessing remarkable cytotoxicity and alkylating and anticancer activity against selected tumor cell lines.

Dissertation (Ph.D.), California Institute of Technology. Chromone derivatives were synthesized from 2,3-allenoic acids and benzynes in good yields under mild conditions. The benzyne intermediate undergoes 1,2-addition with the carbonyl group, followed by ring opening, conjugate addition, and protonolysis to afford chromone derivatives.
