Synthesis of New N-(Trifluoroacetyl) Doxorubicin Analogues
摘要:
Four new 14-O-acyl derivatives of N-(trifluoroacetyl) doxorubicin possessing a terminal primary amino group have been synthesized in a two steps process under mild reaction conditions.
Synthesis and cellular uptake of a fluorescently labeled cyclic PNA-based compound
摘要:
A cyclic hexameric PNA-based compound labeled with fluorescein has been prepared following the liquid phase FPB strategy. Its cellular uptake, without and with electroporation, has been investigated by fluorescence microscopy. (C) 2004 Elsevier Ltd. All rights reserved.

charged guanidine replaces the phosphodiester linkages, tethering to Hoechst33258 fluorophore by varying lengths has been synthesized. A pentameric thymidine DNG was synthesized on solid phase in the 3' --> 5' direction that allowed stepwise incorporation of straight chain amino acid linkers and a bis-benzimidazole (Hoechst33258) ligand at the 5'-terminus using PyBOP/HOBt chemistry. The stability
Synthesis of T-containing phosphorodiamidatemorpholino oligomers (PMO) by H-phosphonate method on solid support has been reported for the first time. Initially, 5-mer then 15-mer of T-containing PMO using H-phosphonate-T monomer was synthesized on polystyrene resin bead. The phosphonamidate backbone was oxidized by iodine–dimethylamine mixture followed by the cleavage from solid support by aqueous

Compositions and methods for fluorescent detection of nucleic acids are provided. The compositions can be detected by fluorescence when hybridized to a nucleic acid containing a target sequence, but are non-fluorescent in the non-hybridized state. Alternatively, the fluorescence properties of the compositions change in a detectable manner upon hybridization to a nucleic acid containing a target sequence. Methods for synthesis and methods of use of the compositions are also provided.
