DNA-binding studies of the natural β-carboline eudistomin U


, : DNA-binding studies of the natural β-carboline eudistomin U. Bioorganic & Medicinal Chemistry Letters 26(19): 4705-4708

Eudistomin U is a member of the β-carboline class of heterocyclic amine-containing molecules that are capable of binding to DNA. The structure of eudistomin U is unique since it contains an indole ring at the 1-position of the pyridine ring. While simple β-carbolines are reported to intercalate DNA, an examination of the mode of binding of eudistomin U has been lacking. We report preliminary spectroscopic (UV-Vis, thermal denaturation, CD) and calorimetric (DSC) data on the binding of eudistomin U to DNA, which suggest that eudistomin U binds weakly according to a mechanism that is more complicated than other members of its class.
