Abstract:
A method for enhancing cellular uptake and redistributing gene regulating polyamides from the extranuclear areas in eukaryotic cells to the nucleus thereof. The method consists of administering to the eukaryotic cells a molecular trafficking compound. The administered molecular trafficking compound affects cellular pathways and mechanisms that accumulate polyamides in cytoplasmic vessicles and/or efflux polyamides from the intracellular regions of cell. The method also includes modifying polyamides to contain negatively-charged or acidic moieties wherein the moieties inhibit the accumulation of polyamides in cellular lysosomes. By affecting the cellular pathways and mechanisms, the polyamides are redistributed throughout the cell, whereby nuclear accumulation of the polyamides is enhanced.
Abstract:
The present invention is directed to protected amino acid halide monomers and oligomers, and to their use in the efficient sythesis of polyamides. The present invention is further directed to the use of -haloenamine reagents, which may optionally be immobilized, for the preparation of the amino acid halides.
Abstract:
The present invention is directed to the means by which to alter the binding affinity and/or specificity of a compound with a sequence of DNA in the minor groove of a double-strand thereof. More particularly, the present invention is directed to a synthetic and/or non-naturally occurring compound (e.g., an analog of a polyamide oligomer or polymer) which contains at least one hydrogen bond donor moiety and at least one hydrogen bond acceptor moiety, wherein the latter moiety or "building block" has a fused, bicyclic structure which is heteroaromatic, said structure having a heteroatom therein which acts as a hydrogen bond acceptor to bind guanine in the minor groove of the dsDNA sequence, and which is incapable of forming a tautomer. In one particular embodiment of the synthetic and/or non-naturally occurring compound, the fused, bicyclic structure occupies an initial or first terminal position within the compound.
Abstract:
Processes and compositions are provided for regulating COX2 gene expression in a cell. The process includes selecting a polyamide composition comprising N-methyl pyrrole (Py) and N-methyl imidazole (Im) to provide specific binding to DNA at a COX2 gene target site in a cell. The polyamide is then combined with the cell containing the COX2 gene, wherein the polyamide binds to the COX2 gene promoter target site and regulates transcription of the COX2 gene.
