N-1,N-3-Bis(4-amidinophenyl)propane-1,3-diamine (BAPPA, R = H) is a bisaminobenzamidine fluorogenic derivative that displays a large increase in its emission fluorescence when bound to the minor groove of specific A/T DNA sites (K-d for an AATT site similar to 79 +/- 6 nM). Moreover, the structural characteristics of BAPPA allow the easy introduction of functional groups that protrude out of the DNA surface.
