Polyfunctional compounds comprise a novel class of therapeutic agents for the treatment of multi-factorial diseases. A series of 2-Phenyl-4H-chromen-4-one and its derivatives (5a–n) were designed, synthesized, and evaluated for their poly-functionality against acetylcholinestrase (AChE) and advanced glycation end products (AGEs) formation inhibitors against Alzheimer’s disease (AD). The screening results showed that most of them exhibited a significant ability to inhibit AChE AGEs formation with additional radical scavenging activity. Especially, 5m, 5b, and 5j displayed the greatest ability to inhibit AChE (IC50 = 8.0, 8.2, and 11.8 nM, respectively) and AGEs formation (IC50 = 55, 79, and 54 μM, respectively) with good antioxidant activity. Molecular docking studies explored the detailed interaction pattern with active, peripheral, and mid-gorge sites of AChE. These compounds, exhibiting such multiple pharmacological activities, can be further taken a lead for the development of potent drugs for the treatment of Alzheimer’s disease.

A series of flavones, carrying halogens, methoxy and nitro groups at various positions were synthesized by the Baker-Venkataraman rearrangement and were subsequently converted to 4-thioflavones and 4-iminoflavones. The synthesized compounds were evaluated for their in vitro antifungal activity against Trichophyton longifusus, Candida albicans, Aspergillus flavus, Microsporum canis, Fusarium solani and Candida glabrata. All synthesized compounds showed significant activity against T. longusus, A. flavus, M. canis and F. Solani but inactive against C. albicans and C. glabrata, respectively. 2-phenyl-4H-1-benzopyran-4-thiones were relatively more active than flavones and 4-iminoflavones. However, some compounds were even more active than standard miconazol and amphotericin B drugs.
Efficient synthesis of nitroflavones by cyclodehydrogenation of 2prime;-hydroxychalcones and by the Baker-Venkataraman method
Barros, Ana I. R. N. A.,Silva, Artur M. S.

Several nitroflavone derivatives were synthesized by cyclodehydrogenation of 2′-hydroxychalcones and by the Baker-Venkataraman approach, starting from 2′-hydroxyacetophenones and benzoic acid derivatives. Nitroflavones synthesised by the first synthetic a
