title: Propynyl groups in duplex, hairpin and triplex DNA: 7-deazapurines and 9-deazapurines.
abstract: Oligonucleotides containing 7-deazapurines or 9-deazapurines with propynyl groups at the 7- or 9-position were prepared. The stabilizing effect of the propynyl group was studied on DNA duplexes, hairpins and triplexes.
