Altohyrtin A (spongistatin 1, cinachyrolide A) is a polyether macrolide originally isolated from the Okinawan marine sponge Hyrtios altum by Kobayashi et al. in 1993, It was also found in an Indian species of Spongia by Pettit et al, and in a Japanese species of Cinachyra by Fusetani et al. It has potent anti-cancer activity.
