title: A homopolymer of the potent antitumor drug 2'-deoxy-5-fluorouridylate.
abstract: Poly(5-fluoro-2'-deoxyuridylic acid) was synthesized and its properties were compared with those of poly(dT) and poly(dU). It readily complexed with poly(dA). The 1:1 complex melted at about 20 degrees C lower than poly(dA) . poly(dT). A triple-stranded helix, poly(dA) . 2 poly(dF5U) was formed only in high salt (2.0 M NaCl).
