Mol. framework models of the complexes formed between the salts N+H3CHRCONHCH2CH2N+Me2N.2Br- (I), N+H3C(CO2-)H(CH2)nH+H3Cl- (n = 2, 3, and 4) (II), N+HEC[CH2]4N+H3]HCONHCHRCO2-Cl-, (III), and N+H3CHRCH2N+H3.2Cl- (R = Me and CO2H) (IV) and adjacent phosphate anions of a helical polynucleotide chain were examined in detail; 15-, 16-, 17-, and 18-membered rings are formed as the result of complexing the salts I-IV to the nucleic acid helix. Certain conformations are not as favorable as other. Moreover, it is possible to predict which of the two optical isomers of I-IV should interact to a greater extent with a nucleic acid helix. The results using 11 different sets of optical isomers of I-IV on three different helical structures, i.e., poly I-poly C, poly A-poly U, and calf thymus DNA, were predicted correctly and consistently.
