The phylum Cnidaria is a large, diverse and ecologically important group of marine invertebrates, which produce powerful toxins and venoms. The number of marine natural product from cnidarians isolated from class Anthozoa. Among the Anthozoa, the order of zoanthids are sessile, clonal and mostly brightly colored invertebrate which produce high biodiversity of cytolitic, neurotoxic and cardiotoxic compounds. Zoanthids containing palytoxins are reportedly among the most toxic marine organisms known. In addition, a high concentration of zoanthamine alkaloids extracted from this group.The zoanthamine alkaloids were isolated over 20 years ago, exhibit a broad range of biological activities.The best studied and most well-known biological activity of zoanthamine derivative significantly suppressed bone resorption and enhanced bone formation.
