Investigation of Anti cancer properties of Schiff base compound based on 4, 5, 6, 7-tetrahydrobenzo[d]thiazole

In this study, a new Schiff base compound was synthesized using the condensation reaction of 2-hydroxy-1-naphthaldehyde with 4, 5, 6, 7-tetrahydrobenzothiazole-2, 6-diamine. The product was characterised by using FT-IR and 1H-NMR techniques. The interaction of this compound with DNA extracted from calf thymus (ct-DNA) was studied by the fluorescence emission and circular dichroism (CD). In addition, the binding ability and the interaction type of the corresponding Schiff base with ct-DNA was determined by monitoring of DNA denaturation data and bonding and thermodynamic parameters of the interaction of compound with DNA. Finally, the anti-cancer properties of this compound were investigated on two categories of HepG2 and MCF-7 cancer cells. The results showed the groove binding of the compound to DNA and the IC50 values of the compound for the two cell lines HepG2 and MCF-7 were 34.52 21 2.21 and 7.75 70 3.70 μM, respectively.
