The flavonoids are phenyl substituted chroman (benzopyran derivatives) consisting<br>of a 15-carbon basic skeleton (C6-C3-C6), composed of a chroman (C6-C3) nucleus (the benzo ring A and<br>the heterocyclic ring C), also shared by the tocopherols, with a phenyl (the aromatic ring B), substitution<br>usually at the 2-position. Different substitutions can typically occur in the rings, A and B. Several plants<br>and spices containing flavonoid derivatives have found application as disease preventive and therapeutic<br>agents in traditional medicine in Asia for thousands of years. Various analogues of 3-methylflavones<br>were synthesised, purified and characterised by UV, IR, 1HNMR and mass spectrometry .All the synthesised<br>compounds were evaluated for their cytotoxic activity by MTT assay against HeLa cell line. Most of the<br>compounds show moderate activity, whereas the compounds like FA-04.FA-20,FA-10 and FA-13 have<br>shown good activity having IC50 value 22.00,25.49.26.24 and 26.35 ?g/ml respectively, in comparison<br>to standard molecule Cisplastin had IC50 value 6- 12.5 ?g/ml . Thus it appears the presence of 3- methyl<br>group in the flavone nucleus significantly influences the log ā€˜P’ value of all the twenty test compounds.</p><p>The prominent activity the of above compounds is probably because of 3-methyl and N, N-dimethyl amino<br>substitution on 4’- position of flavonoid nucleus.</p> ER -
