A. Tatibouet et al., Synthesis and study of an acridine substituted Troger's base: preferentialbinding of the (-)-isomer to B-DNA, CHEM COMMUN, (2), 1999, pp. 161-162
The acridine substituted Troger's base 4 was prepared, resolved and the (-)
-(7R,17R) enantiomer was shown to bind preferentially to calf-thymus B-DNA.
