摘要:
This invention relates to substituted pyrido(3,2-d)pyrimidine derivatives, their pharmaceutically acceptable salts, N-oxides, solvates, pro-drugs and enantiomers, possessing unexpectedly desirable pharmaceutical properties, in particular which are highly active immunosuppressive agents, and as such are useful in the treatment in transplant rejection and/or in the treatment of certain inflammatory diseases. These derivatives are also useful in preventing or treating cardiovascular disorders, disorders of the central nervous system, TNF-α related disorders, viral diseases (including hepatitis C), erectile dysfunction and cell proliferative disorders.

摘要:
The invention provides pteridine nucleotides of formula (I) which are highly fluorescent and which can be used in the chemical synthesis of fluorescent oligonucleotide. The invention further provides for fluorescent oligonucleotide comprising one or more pteridine nucleotides. In addition the invention provides for pteridine nucleotide triphosphates which may be used as the constituent monomers in DNA amplification procedures. The pteridine nucleotides are more stable and possess higher quantum yields than structurally similar pteridine nucleotides.

摘要:
The new compound 4-amino-3-aminomethylpiperidine is manufactured by hydrogenating 4-amino-3-cyano-1,2,5,6-tetrahydropyridine under pressure and in the presence of ammonia and a hydrogenation catalyst. The 4-amino-3-cyano-1,2,5,6-tetrahydropyridine used as the starting substance can be obtained by cyclization of bis-cyanoethylenated ammonia. The new compound 4-amino-3-aminomethylpiperidine represents a valuable curing agent for epoxide resins, and advantageously 0.5 to 1.3 equivalents of nitrogen-bonded active hydrogen atoms of the 4-amino-3-aminomethylpiperidine are used per 1 equivalent of epoxide groups of the polyepoxide compound.

摘要:
The present invention discloses novel and improved nucleosidic and nucleotidic compounds that are useful in the light-directed synthesis of oligonucleotides, as well as, methods and reagents for their preparation. These compounds are characterized by novel photolabile protective groups that are attached to either the 5′- or the 3′-hydroxyl group of a nucleoside moiety. The photolabile protective group is comprised of a 2-(2-nitrophenyl)-ethyoxycarbonyl skeleton with at least one substituent on the aromatic ring that is either an aryl, an aroyl, a heteroaryl or an alkoxycarbonyl group. The present invention includes the use of the aforementioned compounds in light-directed oligonucleotide synthesis, the respective assembly of nucleic acid microarrays and their application.
