Natural Product Identification
Common Namen-[13,14,15-trimethoxy-5-(methoxycarbonyl)tricyclo[9.4.0.0²,⁷]pentadeca-1(15),2,4,6,11,13-hexaen-8-yl]ethanimidic acid
DescriptionAllocolchicine belongs to the class of organic compounds known as allocolchicine alkaloids. These are alkaloids with a structure based on the tricyclic allocolchicine skeleton, which consists of a dibenzocycloheptane where the cycloheptane moiety carries the N-acetamide group. n-[13,14,15-trimethoxy-5-(methoxycarbonyl)tricyclo[9.4.0.0²,⁷]pentadeca-1(15),2,4,6,11,13-hexaen-8-yl]ethanimidic acid is found in Colchicum decaisnei. Allocolchicine is an extremely weak basic (essentially neutral) compound (based on its pKa).
