CTX3C is a cyclic polyether compound with a rigid structure, consisting of 13 rings fused by ether bonds. It is a secondary metabolite synthetized by microalgae in the genera Gambierdiscus and Fukuyoa [1,2]. CTX3C is also found in the tissues of marine invertebrates and fish from the Pacific region [1,3].

| Category | Natural product – Poison |
| Target and biological activity | Ciguatoxins (CTXs) are potent marine neurotoxins that act as activators of voltage-gated sodium channels (VGSCs) [4]. They bind at site 5 of the alpha subunit of VGSCs resulting in the opening of the Na+ channels, and firing of repetitive action potentials. |
