摘要:
Peptide derivatives represented by the general formula (I) and pharmaceutically acceptable salts thereof, processes for preparing the derivatives or the salts, and use of both: (I) wherein X is CHOH- or CO-; R?1 and R2¿ are each hydrogen or substituted oxycarbonyl; R3 is substituted oxycarbonyl; R4 is hydroxyl, lower alkoxy, optionally substituted piperazinyl, or the like; R5 is a side chain (R) of an optionally protected a-amino acid; R6 is hydroxyl, lower alkoxy, or the like; m is 0 or 1; and n is an integer of 2 to 6.
摘要:
Novel 4,6-diarylpyrimidine derivatives represented by general formula (1), salts thereof, a process for producing the same, and a drug comprising the same as the active ingredient, wherein R represents a heterocycle or amino optionally substituted by one to four lower alkyl groups; and Ar represents phenyl, naphthyl or an aromatic heterocycle optionally having one to four substituents. The compounds have an excellent effect of inhibiting neovascularization and are useful as a remedy for solid tumor, rheumatism, diabetic retinopathy and psoriasis.
摘要:
Compounds represented by general formula (I) and having both an IL-4 production inhibitory activity and a PDE(IV) inhibitory activity; a medicinal composition comprising an effective amount of any of the compounds and a pharmaceutical carrier; a remedy or preventive for acute and chronic inflammatory diseases; and an antiallergic agent or antiphlogistic agent: wherein A is a triazole group; R1 and R2 are the same or different and each is an alicyclic hydrocarbon group or an aliphatic or alicyclic hydrocarbon group optionally having an aromatic hydrocarbon group; R3 is hydrogen or a substituent; and R4 is hydrogen or a group protecting the nitrogen atom. Also provided are methods of using the compounds represented by formula (I) for the production of the medicinal composition, the remedy or preventive for acute and chronic inflammatory diseases, and the antiallergic agent or antiphlogistic agent; and a method for the therapy and/or prevention of acute and chronic inflammatory diseases.
摘要:
