Neoxaline is a bio-active Aspergillus japonicus isolate. It is an antimitotic agent and shows weak inhibitory activity of blood platelet aggregation. It stimulates the central nervous system.[1][2] It has been synthesized through the "highly stereoselective introduction of a reverse prenyl group to create a quaternary carbon stereocenter using (−)-3a-hydroxyfuroindoline as a building block, construction of the indoline spiroaminal via cautious stepwise oxidations with cyclizations from the indoline, assembly of (Z)-dehydrohistidine, and photoisomerization of unnatural (Z)-neoxaline to the natural (E)-neoxaline."[3]
