Description

Curcumin, a derivative of the spice turmeric, has been shown to display several beneficial health properties, including a potential to serve as a chemopreventive agent. It is an ideal research subject for investigating chemopreventive potential because it can be implemented into the diet. This study examined the products of reactions between curcumin and both 2‘-deoxyguanosine (dG) and 2‘-deoxyadenosine (dA). Curcumin was reacted with dG and dA (in separate reaction vessels) in the presence of a phosphate buffer containing L- arginine, as well as in a Tris-HCl buffer. TLC was used to determine which reactions formed products.

Those reaction products were then analyzed using NMR to determine chemical structural features. In addition, calf-thymus DNA (CT-DNA) was reacted with curcumin in a Tris-HCl buffer. After isolation, the treated CT-DNA was digested with various enzymes; the products were isolated with SPE. The dG and dA products and the treated CT-DNA digest were analyzed in sequence using LCMS. The comparison of CT- DNA reaction products and the dG and dA reaction allowed for conclusions to be determined about the ability of curcumin to bind to DNA.
