title: A pyrimidopyrimidoindole nucleoside (dC PPI): photophysical properties and thermal stability of the modified DNA duplexes.
abstract: A new fluorescent deoxycytidine analog, 10-(2-deoxy-beta -D-ribofuranosyl)-pyrimido[4',5' :4,5]-pyrimido[1,6-a]indole-6,9(7H)-dione (dC(PPI)) was synthesized. Its fluorescent properties were studied in detail. It was found that this fluorescent nucleoside dC(PPI) could be used as a fluorescent label for DNA probes with minimal disturbance of their overall structure.
