Metabolite Identification
Common Name8-Methyldihydrochelerythrine
Description8-Methyldihydrochelerythrine belongs to the class of organic compounds known as dihydrobenzophenanthridine alkaloids. These are alkaloids containing a dihydrobenzophenanthridine skeleton, which is a tetracyclic compound containing a benzene fused to a dihydrophenanthridine moiety. 8-Methyldihydrochelerythrine is a moderately basic compound (based on its pKa). Outside of the human body, 8-methyldihydrochelerythrine has been detected, but not quantified in, fruits and herbs and spices. This could make 8-methyldihydrochelerythrine a potential biomarker for the consumption of these foods.
