摘要:
To provide the compounds inhibiting PDE 7 selectively, and therefore, enhance cellular cAMP level. Consequently, the compound is useful for treating various kinds of disease such as allergic disease, inflammatory disease or immunologic disease. The compound is pyridinylpyrazolopyrimidinone compound represented by the following formula (IA) or (IB): especially, R1 is cyclohexyl or cycloheptyl group, R2 is methyl; R3 is a group: -NR5R6 or -S(O)0-2R8; hydrogen atom; nitro group; cyano group; a halogen atom; heteroaryl group; and R4 is methoxy or ethoxy group.
摘要:
A thienopyrazole derivative represented by the following formula (I): [wherein preferably, R1 is cyclohexyl, cycloheptyl, or tetrahydropyranyl; R2 is methyl; R3 is hydrogen; and R4 is -CONR5R6 (wherein either of R5 and R6 is hydrogen)]. It has selective inhibitory activity against PDE7 and thus heightens the intracellular cAMP level to inhibit the activation of T cells. The derivative is hence useful in the prevention and treatment of various allergic diseases and inflammatory/immunologic diseases.
摘要:
ABSTRACT A method for selectively producing stable alpha form crystals of sapropterin hydrochloride is provided. In this method, the alpha form crystal of sapropterin hydrochloride is produced by dissolving sapropterin hydrochloride with hydrochloric acid at a concentration of not less than 4 mol/L at not less than 70degrees C; adding heated ethanol to the solution; and cooling the solution at a cooling rate of not faster than 3degrees C/min to a temperature of 40 to 55degrees C to precipitate the crystals.

wherein R 1 indicates an aldopyranose residue, R 2 indicates a hydrogen atom or hydroxyl group, A indicates -CH 2 -, - CH(OH)-CH 2 - or -CH=CHCH 2 -, Z indicates -O- or -CH 2 -, when Z is -O- and x is an integer of 4 to 16, y indicates an integer of 26 to 35, when Z is -O- and x indicates an integer of 17 to 25, y indicates an integer of 0 to 35, when Z is -CH 2 - and x indicates an integer of 4 to 15, y indicates an integer of 26 to 35, and when Z is -CH 2 - and x indicates an integer of 16 to 25, y indicates an integer of 0 to 35 and a drug containing the glycolipid derivative for treatment of autoimmune arthritis and other autoimmune disease, bronchial asthma and other allergic diseases or diseases in which NKT cells or stimulation of NKT cells is known to be participating in the deterioration of conditions.
摘要:
A novel dosage regimen of GLP-1 receptor agonists causes little or no side effects or drug interactions and is suitable for improving insulin resistance. Also provided is an insulin resistance improver for use in the dosage regimen. The dosage regimen comprises repeatedly administering, preferably in a non-invasive manner, a GLP-1 receptor agonist at least before eating for a predetermined period of time to create a condition similar to what is observed with postprandial temporary secretion of the endogenous GLP-1 receptor agonist, rather than administering it continuously. This creates a similar or enhanced variation in the plasma levels of GLP-1 receptor agonist as compared to the circadian variation of the endogenous GLP-1 receptor agonist in a healthy individual. A pharmaceutical composition for use in the dosage regimen containing GLP-1 receptor agonist as an active ingredient is also provided.
摘要:
A pharmaceutical for promoting neogenesis or regeneration of pancreatic β cells which produces and secretes insulin and for promoting insulin production in β cells, comprising ghrelin or a derivative thereof as an effective component.
摘要:
A process for producing a peptide having a desired biological activity via gene recombination characterized in that an accessory peptide is added to the target peptide followed by the expression thereof. Use of this process makes it possible to prevent agglutination in the recovery and purification steps with the regulation of isoelectric points, to achieve an elevated yield in ion exchange chromatography, to improve the solubility of a fused protein in an enzymatic reaction wherein the target peptide is expressed as the fused protein with another protein and then liberated by enzymatic cleavage, to improve the solubility of the target peptide in an enzymatic reaction wherein the peptide should be enzymatically modified, etc., thus elevating the purification efficiency and yield of the target protein.
