Fig. 5From: Natural product-inspired strategies towards the discovery of novel bioactive moleculesNaturally occurring hybrid molecules. (Molecular structure of ibogaine, vindoline, vincristine). The structure of vincristine, two vinca alkaloids, are formed by two polycyclic moieties, namely vindoline (red) and catharanthine (blue). The catharanthine portion is also the basic motif found in the ibogaine molecule.)Back to article page
