desacetoxyvindoline
IUPAC 名称
methyl 12-ethyl-10-hydroxy-5-methoxy-8-methyl-8,16-diazapentacyclo[10.6.1.0¹,⁹.0²,⁷.0¹⁶,¹⁹]nonadeca-2,4,6,13-tetraene-10-carboxylate
描述
Desacetoxyvindoline is a member of the class of compounds known as plumeran-type alkaloids. Plumeran-type alkaloids are alkaloids with a structure based on the plumeran skeleton. Plumeran is a pentacyclic compound that consists of a pyrrolidine ring shed to the quinoline moiety of pyrido[3,2-c]carbazole ring system. Desacetoxyvindoline is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Desacetoxyvindoline can be found in a number of food items such as welsh onion, kiwi, white cabbage, and pecan nut, which makes desacetoxyvindoline a potential biomarker for the consumption of these food products. 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). The metabolite is a substrate for desacetoxyvindoline 4-hydroxylase (D4H) which catalyzes a hydroxylation to yield deacetylvindoline .
