摘要:
To provide an excellent agent for prevention or treatment of an inflammatory disease.The agent for prevention or treatment of an inflammatory disease contains a thymidine phosphorylase inhibitor as an active ingredient, wherein when the thymidine phosphorylase inhibitor is 5-chloro-6-(2-iminopyrrolidin-1-yl)methyl-2,4(1H,3H)-pyrimidinedione or a salt thereof, the inflammatory disease is an inflammatory disease other than inflammatory bowel disease.
摘要:
To establish an immunoassay method for human OPRT.The method for assaying human orotate phosphoribosyltransferase protein includes employing, in combination, an anti-human orotate phosphoribosyltransferase antibody which recognizes an epitope present in a region of 86th to 108th amino acid residues from the N-terminus of human orotate phosphoribosyltransferase, and an anti-human orotate phosphoribosyltransferase antibody which recognizes an epitope present in a region of 454th to 474th amino acid residues from the N-terminus of human orotate phosphoribosyltransferase.
摘要:
This invention provides a double-stranded oligonucleotide or a derivative thereof which comprises 15 to 40 base pairs, wherein at least one side of the strands contains at least one nucleotide sequence represented by 5'-TTTSSCGS-3' (S is G or C). Also, since the compound of the present invention can inhibit expression of growth-related genes which are regulated by E2F, through its function to undergo sequence-specific competitive inhibition of the binding of E2F protein to the transcription region at a low concentration, a pharmaceutical composition containing the inventive compound as its active ingredient is useful as a drug having low side effects for use in the prevention and treatment of cancers.
