Description: DA-E 5090 is deacetylated form of E5090, is pharmacologically active metabolite of E 5090, is interleukin-1 antagonist. DA-E 5090 is a novel inhibitor of IL-1 generation, in vitro inhibitory effects on the generation of IL-1 by human monocytes. E5090 is an orally active inhibitor of IL-1 generation, being converted in vivo into the pharmacologically active deacetylated form (DA-E5090). In vitro effects of DA-E5090 on the generation of IL-1 by human monocytes stimulated with LPS were examined. DA-E5090 inhibited both IL-1 alpha and IL-1 beta generation by human monocytes stimulated with 1 microgram/ml of LPS in a dose dependent-manner (1-10 microM), as determined by LAF assay and ELISA. Northern blotting analysis indicated that DA-E5090 inhibits transcription of IL-1 alpha and IL-1 beta m-RNAs.
