  gram-scale synthesis of flavones is described by a one-pot straightforward sulfoxide-mediated Knoevenagel condensation/intermolecular oxa-Michael annulation/sulfoxide elimination process of β-(o-hydroxyaryl)-ketosulfones (dual nucleophile) and arylaldehydes (dual electrophile). The expeditious synthetic route sets up flavones, including the bond formation of one CO and one double CC bonds via a formal (5 + 1)

  Glutaminyl cyclase (QC) plays an important role in the pathogenesis of Alzheimer's disease (AD) and can be a potential target for the development of novel anti-AD agents. However, the study of QC inhibitors are still less. Here, phenol-4' (R1-), C5-OH (R2-) and C7-OH (R3-) modified apigenin derivatives were synthesized as a new class of human QC (hQC) inhibitors. The efficacy investigation of these compounds was performed by spectrophotometric assessment and the structure-activity relationship (SAR) was evaluated. Molecular docking was also carried out to analyze the binding mode of the synthesized flavonoid to the active site of hQC. (C) 2016 Elsevier Ltd. All rights reserved.

  The preparation and characterization of some novel 2- and 3-substituted-7-methoxy-4H-1-benzopyran-4-one are presented. The synthesized compounds were evaluated for their uterotrophic, antiuterotrophic and antiimplantation activities in mature female albino rats. 3-Benzyl-7-methoxy-4H-1-benzopyran-4-one (14) showed the highest uterotrophic activity (87%) based on dry uterine weight gain. The antifertility activity, as assessed by the post-coital antiimplantation activity test, was of weak potency for most compounds (14-29%). Among the products, the 2-(4'-methoxyphenyl)-7-methoxy-4H-1-benzopyran-4-one (19) exhibited the highest antiestrogenic activity of 65%. It also elicited 31% of the uterotrophic activity of estradiol.

  A practical and effective approach towards the synthesis of 3-heteroaryl-4H-chromen-4-ones by the oxidative [1,2] rearrangement of the respective 2-heteroaryl chroman-4-ones using thallium(III) p-tosylate is presented. The oxidative rearrangement of α- and β-naphthyl and thiophene substituents behaves like aryl groups; However, pyridyl substituents gave only dehydrogenated products.
