p-Aminophenol derivative compounds and dye compositions containing same
A series of phenylguanidines which bind to the C5a receptor has been developed. The lead compound 1 (IC50=30 mu M), discovered through random screening, has been modified to provide 32 (RPR121154) with submicromolar activity. This compound was shown to further elicit functional antagonism in a human neutrophil C5a stimulated respiratory burst assay. (C) 1997 Elsevier Science Ltd.
