A series of flavones, substituted at the ring B, were synthesized using either Claisen-Schimdt Condensation or Baker-Venkataraman rearrangement. The synthesized compounds were tested for in vitro cytotoxic activity by sulforhodamine B assay against three cell lines of different origin, viz. HepG2, MCF-7, and MOLT-4. The compounds were also tested for a possible antioxidant activity by determination of inhibition of lipid peroxidation. Quercetin was taken as a standard for antioxidant activity. Compound 1c showed the highest cytotoxic activity against MCF-7 (GI50 0.1 μM) and MOLT-4 (GI50 0.1 μM) cell lines and was comparable to adriamycin, the standard used. Compounds 1b, 1g, and 1h also showed promising activity against MCF-7 and MOLT-4 cell lines. In the absence of a hydroxyl group, one or more methoxy groups present on the B-ring (compounds 1c-1e) were major determinants of inhibition of lipid peroxidation.

A series of 2--4H-1-benzopyran-4-one analogues 7a-7e was synthesized by the reaction with 3',4'-diaminoflavone and aliphatic carboxylic acids. 3',4'-Diaminoflavone 6 was prepared via the reduction of 2-(4-amino-3-nitrophenyl)-4H-1-benzopyran-4-one 5a.The compounds 7a-e and 14a-f were tested in vitro for their inhibitory activities against human platelet aggregation induced by collagen, ADP and A23187.The compound with a COOR group as a side chain, 2-(2-akyloxycarbonyl-2,3-dihydro-1,4-benzodioxin -6-yl)-4H-1-benzopyran-4-one 14a-f, haspotent activity, and so compound 13 was also prepared as an analogue of series 14 and tested for its antiaggregator activity. 4H-1-benzopyran-4-one/ benzodioxane/ benzimidazole/ human platelet/ aggregation
