MedKoo CAT#: 111013

CAS#: 479-37-8

Description: Obamegine is a member of isoquinolines and a bisbenzylisoquinoline alkaloid. Isoquinolines show biological activities similar to those of morphinane-, protoberberine-, and benzophenanthridine-type alkaloids. Some callus tissues have produced many kinds of isoquinoline alkaloids, particularly callus tissues of papaver somniferum, thalictrum minus, coptis japonica, and fumaria capreolata. The results show that callus tissues have sufficient biosynthetic ability
