Efficient method for the synthesis of dideoxyuridine-5′-triphosphate fluorescent derivative

A versatile strategy for the design and synthesis of novel ADP conjugates and their evaluation as potential poly(ADP-ribose) polymerase 1 inhibitors

A versatile strategy for the synthesis of [Formula: see text] mimetics was developed, involving an efficient pyrophosphate linkage formation in key conjugates containing a functional amino group which acts as useful reactive anchor for further derivatization. These [Formula: see text] mimetics consist of ADP conjugated through a diphosphate chain to an extended aliphatic linker bearing an aromatic acid residue. A number of conjugates containing aromatic carboxylic acids were found to inhibit poly(ADP-ribose) synthesis catalyzed by poly(ADP-ribose) polymerase-1 (PARP-1). A new class of potential PARP-1 inhibitors mimicking [Formula: see text], a substrate in the PARP-1 catalyzed reaction, was proposed.

Effective Synthesis of Fluorescently Labeled Morpholino Nucleoside Triphosphate Derivatives

Morpholino nucleoside triphosphates (A, U, G, C, T) bearing the active functional amino group tethered to morpholine residue and their fluorescently labeled derivatives were synthesized. All compounds were characterized by (1)H, (13)C, and (31)P NMR, and mass spectrometry. A possibility of using fluorescently labeled morpholino nucleoside triphosphates as chain terminators in DNA sequencing is discussed.
