Desacetoxyvindoline is a terpene idole alkaloid produced by the plant Catharanthus roseus. Desacetoxyvindoline is a product formed by the methylation of the nitrogen on the indole ring by the enzyme 3-hydroxy-16-methoxy-2,3-dihydrotabersonine N-methyltransferase (NMT).[1] The metabolite is a substrate for desacetoxyvindoline 4-hydroxylase (D4H) which catalyzes a hydroxylation to yield deacetylvindoline.[2]
