  All the synthesized curcumin derivatives 4a–n were screened for antioxidant and antimicrobial activity. Biological activity data of the synthesized showed that most of the synthesized compounds exhibited greater antioxidant and antibacterial activity than curcumin. Geometries of synthesized compounds were optimized by using B3LYP method with 6-31G* basis set. Then, DFT based reactivity descriptors such

  better cytotoxicity effect against three cell lines. According to results of SAR study, it was found that 3,4-dihydropyrimidines of curcumin, 2c, 2d, 2j and 2n exhibited better antioxidant activity than curcumin. A correlation of structure and activities relationship of these compounds with respect to drug score profiles and other physico-chemical properties of drugs are described and verified experimentally

  3,4-Dihydropyrimidinones of curcumin were synthesized in excellent yield by multi-component one-pot condensation of curcumin, substituted aromatic aldehydes and urea/thiourea under solvent free conditions using SnCl2 center dot 2H(2)O catalyst. All the synthesized compounds have been characterized by IR, H-1 NMR, C-13 NMR, Mass spectra as well as elemental analyses. The synthesized compounds 4a-n were evaluated for their synergistic antimicrobial (antibacterial and antifungal) activity against bacteria and fungi. Zone of inhibition was measured by adopting disc diffusion method. In vitro minimum inhibitory concentrations were measured using broth microdilution and food poisoning method. In addition to this in vitro cytotoxicity of synthesized compounds against three human cancer lines Hep-G2, HCT-116 and QG-56 were also evaluated. Most of the compounds showed interesting antimicrobial and cytotoxic activity as compared to curcumin, that is, the compounds derived from 2-hydroxy benzaldehyde, 4-hydroxy benzaldehyde and 4-hydroxy-3-methoxy benzaldehyde showed the highest biological activity as compared to other compounds.
