As a novel analogue of furocoumarin, 2H-4,8-dimethylfuro [2',3':5,6]naphthol[1,2-b]pyran-2-one 6 was synthesized through Pechmann condensation, etherification, Claisen rearrangement, acetylation, bromine addition and cyclization of 1,5-naphthalenediol. The structures of 6 and its precusors were fully characterized by ^1H NMR, MS, IR and elemental analysis. The DNA-intercalative activity of 6 and 7 was investigated in DMSO-Tris HCl system and their apparent Scatchard binding constants were calculated. It was found that 7 intercalate into DNA more efficiently than 6 due to the different substituents on the furan ring.
