Synthesis and anti-inflammatory in vitro, in silico, and in vivo studies of flavone analogues
摘要:
Chrysin and 7-hydroxy flavone were prepared by Baker-Venkatraman rearrangement followed by esterification at 7th position and replacement of ester with acetamide linking to different heterocyclic moieties synthesized 13a-g and 14a-g series of flavones analogues. These were screened against COX-2 and COX-1 enzymes for inhibition by in vitro assay and COX-2 for in silico docking studies. The compound 14a was found to be most active with IC50 of 3.11 A mu M concentration, with highest binding energy of -12.4 kcal/mole and 77.2 and 80.5 % inhibition at 3 and 5 h post-carrageenan induced in paw oedema.

A one-potsynthesis of novel benzopyran-4-ones is described. In a tandemreaction, organobase-catalysed Michaeladdition of (RCOCH2COR2)-C-1 on chromone-3-carboxylic acid led to decarboxylation and pyran-4-one ring opening of the latter. This was followed by chromone- and/or chromanone ring closure of the resulting Michael adducts when R-1 is an ortho-hydroxyaryl group. Antioxidant testing of 14 derivatives

styrene groups, on the basis of the similarity with papaverine, improves the antispasmodic action of the xanthoxyline derivates. Our results suggest that the methoxyl and carbonyl groups are critical structural points for the antispasmodicactivity of xanthoxylinederivatives. The hydroxyl group improves antispasmodicactivity, but is not fundamental to its manifestation.

A series of chrysin derivatives 8a-8v were prepared and tested in vitro against HCT-116 (human colon cancer cell line), Hela (human cervical carcinoma cell line), DU-145 (human prostate cell line), K562 (human leukemia cell line), and SGC-7901 (human gastric cancer cell line). The chemical structures of these compounds were confirmed by means of MS, IR, H-1 NMR, C-13 NMR, and elemental analysis. Among these derivatives, 7-(2-(piperazin-1-yl)ethoxy)-5-hydroxy-2-phenyl-4H-chromen-4-one, 8n, had the strongest activity against HCT-116, Hela, DU-145, K562, and SGC-7901 cells.
