Abstract: The structure previously assigned to the phenolic noraporphine alkaloid, (-)-norannuradhapurine has been confirmed by a total synthesis of the racemic alkaloid in which the key step involved the formation of the C ring by a radical-initiated cyclization. although inactive against Staphylococcus aureus ATCC25932, Escherichia coli ATCC10536 and Candida albicans ATCC90028, (±)-norannuradhapurine inhibits the production of NO, PGE2, TNF-a, IL-1b and IL-6 and the expression of iNOS and COX-2 in RAW 264.7 macrophages stimulated with LPS in vitro.
Keywords: Alkaloid; Anti-inflammatory Activity; Aporphine; Isoquinoline; Synthesis; Radical Cyclization
