OBJECTIVEStructure based drug design of curcuminanalogues including 3D QSAR & Moleculardocking with maestro.To synthesize the high scored curcumin analogue and confirm the structure by FT-IR,NMR and TLC methods.To establish the anticancer activity of high scored curcumin analogue by colonic cancer cell line and ovarian cancer cell line.
curcumin act by multitude of different mechanisms, including transcription,corepressors and gene regulating apoptosis. Unlike most drugs curcumin shows low toxicity data(no dose limiting toxicity up to 10g/day) We use daily turmeric in our food, even then cancer potential in India is higher? Low bioavailability due to poor solubility & instability in aqueous solution & alkaline pH. So design and synthesis of new curcumin analogues in which modified beta keto enolic moiety may improve activity.
