Common Name(1r,2r,4r,5r,7r,8r,9r,10r,13r,16s,17r)-11-ethyl-13-methyl-6-methylidene-11-azahexacyclo[7.7.2.1⁵,⁸.0¹,¹⁰.0²,⁸.0¹³,¹⁷]nonadecane-4,7,16-triol
Description12-Epinapelline belongs to the class of organic compounds known as napelline-type diterpenoid alkaloids. These are alkaloid diterpenoids with a structure based on the napelline skeleton, which is a hexacyclic compound, with an additional C-20-C-7 bond in the kaurane-type.
