A promising benzimidazole derivative
1-(4-methybenzyl)-2-p-tolyl-1H-benzo[d]imidazole (MBTBI) has been synthesized and
characterized by single crystal XRD, NMR, mass and IR spectral techniques. The
mutual interaction of this benzimidazole derivative (MBTBI) with bovine serum
albumin (BSA) was investigated using solution spectral studies. The fluorescence
quenching mechanism of BSA by MBTBI was analyzed and the binding constant has
been calculated. The binding distance between these two was obtained based on the
theory of Forester's non-radiation energy transfer (FRET). The effect of some
common ions on the binding constant was also examined.
