title: Solid-phase synthesis of oligomeric deoxynucleic-thiourea (DNT) and deoxynucleic S-methylthiourea (DNmt): a neutral/polycationic analogue of DNA.
abstract: A solid-phase synthesis for oligomeric DNmt is reported. Synthesis proceeds in 3'-5' direction and involves coupling of a protected 3'-isothiocyanate with the corresponding 5'-amine of the growing oligo chain. The difference in oligomeric thiourea/S-methylthiourea binding to DNA is investigated.
