| pubmed-article:9990467 | pubmed:abstractText | A series of regioisomeric derivatives of a 1-methylindole-4,7-dione were synthesised, substituted with a 2-acetoxybenzoate leaving group linked through the (indol-2-yl)methyl or (indol-3-yl)methyl (or propenyl) positions. Reductive elimination of the leaving group occurred from the (indol-3-yl)methyl derivatives but not the 2-substituted regioisomers, indicating that only the C-3 position may be utilised in bioreductively-activated drug delivery, which was demonstrated with an aspirin prodrug. | lld:pubmed |
