摘要:
Modified physiologically active protein which can be produced by reacting a physiologically active protein having a molecular weight falling within the range of from 1 x 10 to 2 x 10 and carrying at least one Gln residue serving as the substitute of transglutaminase with a branched ligand consisting of an amino acid derivative having a lower binding affinity to the asialoglycoprotein receptor located on hepatic parenchymal cells than that to asialoorsomucoid and carrying an amino group and a galactose (Gal) or N-acetylgalactosamine (GalNAc) group serving as the substrate of transglutaminase in the presence of a transglutaminase originating in a microorganism to thereby form an amide bond between the gamma -carboxyamide group of the glutamate residue in the physiologically active protein and the terminal amino group in the branched ligand; and a process for producing the same.
摘要:
Phenylalanine derivatives represented by general formula (1) or pharmaceutically acceptable salts thereof: wherein x represents an interatomic bond, -O-, etc.; Y and Z represent each -C(=O)-, etc.; A represents a specific substituted phenyl group, a specific nitrogen-containing heterocycle, etc.; C represents hydrogen, alkly, etc.; D and E represent each alkyl or D and E may be bonded to each other to form a ring, etc.; F and G represent each hydrogen or alkyl, or F and G may be bonded to each otherto form a ring, etc.; n is from 0 to 2; K represents OR7, NR7R8, R7, etc.; and J and J' represent each hydrogen, halogeno, etc. These derivatives and analogs thereof show an α 4 integlin inhibitory activity and are usable as remedies for various diseases relating to α 4 integlin.
摘要:
Antitumor agents containing as the active ingredients stilbene derivatives and platinum coordination compounds. Owing to the combined use of these two types of active ingredients, these agents are expected as useful as highly safe antitumor agents showing a synergistically improved antitumor activity. When used together with the above platinum coordination compounds, the antitumor activity inherent to the stilbene derivatives is further enhanced to give antitumor agents having improved efficaciousness which are particularly adequate for treating malignant tumors. Further, utilization of these active ingredients as drugs or for therapy, etc. as well as methods therefor are provided.

Disclosed is an agent for use in the treatment or prevention of inflammatory bowel disease. Also disclosed is an agent for inhibiting the production of TNF-±. A therapeutic or prophylactic agent for inflammatory bowel disease comprising at least one amino acid selected from the group consisting of lysine, histidine, phenylalanine, methionine, tryptophan, glutamine, glycine, cysteine, cystine and threonine, the amino acid being administered at a dose of 0.1 to 4000 mg/kg per day; and a TNF-± production inhibitor comprising an amino acid selected from the group consisting of histidine, phenylalanine and tryptophan, the amino acid being administered at a dose of 0.1 to 4000 mg/kg per day.
摘要:
Antitumor agents with a combined use of a tublin polymerization inhibitor having an antitumor activity with an antiinflammatory agent. These two active ingredients may be contained in a single preparation. Alternatively, two preparations containing the respective ingredients to be administered separately may be combined with each other. In case of using a tublin polymerization inhibitor as the active ingredient of an antitumor agent, the toxicity of the tublin polymerization inhibitor at the pharmaceutically effective dose can be largely relieved while maintaining the pharmaceutically effective dose and the fatal dose can be increased to thereby broaden the safety range. Moreover, antitumor methods (treatment methods for the treatment, improvement, inhibition of progress, prevention, etc. of tumor in vivo), use of the above two active ingredients in drugs such as antitumor agents, and combined use of the above two active ingredients as drugs such as antitumor agents either simultaneously or separately.
摘要:
A pharmaceutical composition containing a heterocyclic compound of the formula (I) wherein each symbol is as defined in the specification, an isomer thereof, a solvate thereof or a pharmaceutically acceptable salt thereof as an active ingredient has a superior TNF- alpha production suppressing action. Accordingly, it is useful for the prophylaxis or treatment of various diseases caused by abnormal production of TNF- alpha .
摘要:
A peptide which is a fragment of a gastric cancer antigen or modification thereof, eg having the amino-acid sequence SEQ ID NO:1 or SEQ ID NO:2, when bound to an HLA molecule induces a cytotoxic T-cell response that targets a gastric cancer cell. Accordingly, this peptide is expected to be useful as an agent for preventing or treating a gastric cancer.
