摘要:
A monoclonal antibody which immunologically reacts with human VEGF receptor F1t-1, cells having the human VEGF receptor F1t-1, expressed thereon, and the like; a monoclonal antibody having an inhibitory activity against the binding of human VEGF to human VEGF receptor F1t-1; and the diagnosis and treatment of diseases wherein the pathological condition advances by abnormal vascularization, such as propagation and metastasis of solid tumors, arthritis in chronic articular rheumatism, diabetic retinopathy, prematurity retinopathy and psoriasis, by using the monoclonal antibody.
摘要:
The present invention relates to a polypeptide having 25-hydroxyvitamin D 3 -1α-hydroxylase activity, being useful for the prevention, diagnosis and therapeutic treatment of adult diseases such as osteoporosis induced by the decrease of active type vitamin D 3 and catalyzing the final stage of vitamin D 3 activation; and the gene encoding the polypeptide. In accordance with the present invention, the following can be provided; a polypeptide having 25-hydroxyvitamin D 3 -1α-hydroxylase activity, DNA encoding the polypeptide, a recombinant DNA prepared by inserting the DNA in a vector, a transformant carrying the recombinant DNA, a method for preparing 25-hydroxyvitamin D 3 -1α-hydroxylase by using the transformant, a method for preparing 1α, 25-dihydroxyvitamin D 3 comprising using the polypeptide having 25-hydroxyvitamin D 3 -1α-hydroxylase activity, and an antibody recognizing the polypeptide.
摘要:
A depression remedy containing a triazine derivative represented by general formula (I) or a pharmacologically acceptable salt thereof as the active ingredient, wherein R 1 represents hydrogen, (un)substituted lower alkyl or (un)substituted lower alkanoyl; R 2 represents hydrogen, (un)substituted lower alkyl, (un)substituted lower alkenyl, (un)substituted cycloalkyl, (un)substituted aryl, (un)substituted aralkyl or (un)substituted heterocycle; R 3 represents (un)substituted heterocycle; X represents a single bond, O, S, S(O), S(O) 2 or NR 4 , wherein R 4 represents hydrogen or (un)substituted lower alkyl or R 2 and NR 4 are combined with each other to form a 4- to 6-membered (un)substituted nitrogeneous saturated heterocyclic group; and A represents N or CR 5 , wherein R 5 represents hydrogen or (un)substituted lower alkyl.
摘要:
A novel α-2,8-sialyltransferase which is expressed by the gene cloned from animal cells; a cDNA coding for the transferase; a method of detecting α-2,8-sialyltransferase using the cDNA and inhibiting the production of the transferase; a recombinant vector containing the cDNA integrated thereinto; a cell containing the vector; and processes for producing the above. The α-2,8-sialyltransferase invented is useful for producing physiologically active sugar chains, such as ganglioside GD3, and modification thereof.
摘要:
A novel peptide represented by the following general formula and a process for producing the same: X-A-Trp-B-Gly-Thr-E-G-Y wherein, A represents Asn or Asp; B represents His or Lys; E represents Ala or Ser; G represents Ala or Pro; X represents X¹-Gly or X³-Cys-X²; and Y represents hydroxy, lower alkoxy, amino, Y¹-Asp-Z or Y²-Cys-Z. The peptide is isolated from the product of culture of a streptomyces and has an endothelin antagonism and an activity of suppressing the rise of an intracellular calcium or cyclic guanosine-3,5-phosphate concentration caused by endothelin.
