Abstract

The invention provides N,N'-dicyclohexyl-N-higher fatty acid ureide analogs and pharmaceutical application thereof, relating to therapeutic compounds. A pharmaceutical composition of the N,N'-dicyclohexyl-N-higher fatty acid ureide analogs, and pharmaceutically acceptable salts, solvates, hydrates or carriers thereof can be prepared by a method known by the technical personnel in the technical field. The invention relates to a pharmaceutical composition containing pharmaceutically effective amount of compounds disclosed as general formula I. The composition is used for regulating immune response reaction of the organism, and especially used for preparing organ transplantation immunological rejection inhibitors. The N,N'-dicyclohexyl-N-higher fatty acid ureide analogs can be used for preparing immunomodulating drugs, immunosuppressive drugs, drugs for treating immunological rejection reaction, drugs for treating rheumatic arthritis, anti-inflammatory agents, drugs for treating rheumatalgia, drugs for treating autoimmune disease, drugs for treating fever diseases, organ transplantation immunological rejection inhibitors and the like; and the N,N'-dicyclohexyl-N-higher fatty acid ureide analogs can be used in cytological experiments and experimental animal in-vivo researches.

Description

technical field [0001] The present invention relates to therapeutic compounds, in particular to N,N'-dicyclohexyl-N-higher fatty acid ureide analogs and their pharmaceutical uses. Background technique [0002] Regulation of the immune system is desired in many situations, from suppressing autoimmune responses, to controlling infectious diseases and suppressing graft / tissue rejection. The primary approach to alleviating rejection is to pharmacologically suppress the recipient's immune system. Based on this idea, most of the currently used immunomodulatory compounds are immunosuppressive. However, these drugs have serious side effects in their use, such as nephrotoxicity, neurotoxicity, hepatotoxicity, endocrine complications, and effects on bone (New Engl.j.Med.321:1725-1738, 1989; Surgery 97:125 , 1985). Therefore, there is a need to provide a new class of compounds with immunosuppressive effects but without the above-mentioned toxic and side effects for clinical use. ...
