A new asym. cyanine dye has been synthesized and its interaction with different DNA has been investigated. In this dye, BEBO, the structure of the known intercalating cyanine dye BO has been extended with a benzothiazole substituent. The resulting crescent-shape of the mol. is similar to that of the well-known minor groove binder Hoechst 33258. Indeed, comparative studies of BO illustrate a considerable change in binding mode induced by this structural modification. Linear and CD studies indicate that BEBO binds in the minor groove to [poly (dA-dT)]2, but that the binding to calf thymus DNA is heterogeneous, although still with a significant contribution of minor groove binding. Similar to other DNA binding asym. cyanine dyes, BEBO has a large increase in fluorescence intensity upon binding and a relatively large quantum yield when bound. The minor groove binding of BEBO to [poly (dA-dT)]2 affords roughly a 180-fold increase in intensity, which is larger than to that of the commonly used minor groove binding probes DAPI and Hoechst 33258.
