Structure and activity relationships of novel uracil derivatives as topical anti-inflammatory agents
摘要:
In order to create novel, topical anti-inflammatory compounds exhibiting more potent activities than lead compound CX-659S (1), we designed and synthesized various derivatives of 1 focusing on the uracil N(l)- and N(3)-substituents, and evaluated their anti-inflammatory activities via inhibition of the picryl chloride-induced contact hypersensitivity reaction (CHR) in mice. In the course of our structure and activity relationship study, we found that compounds 6k, 6q, and 6r inhibited by approximately 50% the CHR, at 0.1 mg/ear. These activities were essentially equipotent with that of Tacrolimus, a strong immunosuppressant. (C) 2003 Elsevier Ltd. All rights reserved.

The decomposition reactions of N-methyl-N′-aryl-N-nitrosoureas (1) and of N,N′-dimethyl-N′-aryl-N-nitrosoureas (2) were studied kinetically in phosphate buffer solution. All nitrosoureas 1 were easily hydrolyzed even under neutral conditions and the rates of hydrolysis were found to be proportional to the hydroxide ion concentration over pH range 5.4–7.6. General base catalysis by buffer components
