This process, called biotransformation, was applied to marine sponges in an attempt to increase production of psychedelic and other compounds. Marine sponges are known to produce a variety of compounds with activity on the serotonin receptors 5-HT2A and 5-HT2c, similar to other psychedelics. Many of the compounds from the sea with this activity are tryptamines, like those from psychedelic plants and fungi, with a tendency to possess the element bromine. A variety of compounds, many of which are brominated, called aplysinopsins (named after the sponge Thorecta aplysinopsis) are produced by sponges such as Verongia spengelii, Dercitus, Hyrtios erecta, Smenospongia aurea, Thorectandra, Smenospongia and Verongula species. These compounds show various affinities for the serotonin receptors 5-HT2A and 5-HT2C, reflecting psychedelic activity. The marine sponge Geodia barretti produces the brominated tryptamines barettin and 8,9-dihydrobarettin, which showed activity on serotonin receptors 5-HT2A and 5-HT2C, and only 5-HT2C receptor activity, respectively. Alexander Shulgin wrote in Tryptamines I Have Known And Loved (TIHKAL) about many psychedelic tryptamines, including a variety containing the element bromine (5-Bromo-DMT, 5,6-dibromo-DMT, 5,6-dibromo-tryptamine, 5,6-dibromo-N-methyl-tryptamine) which were known to be produced by marine sponges (Smenospongia auria, S. echin, Polyfibrospongia maynardii). He went on to write “I had the fantasy of trying to scotch the rumor I’m about to start, that all the hippies of the San Francisco Bay Area were heading to the Caribbean with packets of Zig-Zag papers, to hit the sponge trade with a psychedelic fervor.” Beyond psychedelic activity, many of these and similar compounds show anticancer and antiviral activity, clearly indicating the importance of the marine environment for creative solutions to human health. Here, research is presented on biotransformations using marine sponges, tryptamine, and bromine. Owing to the fluorescent character of tryptamines, simple proof in the form of thin layer chromatography (TLC) clearly indicates some degree of biotransformation products. Cultivation and testing of 81 sponge samples on an Indonesian pearl farm and nearly 400 sponge cultures on a Japanese pearl farm are presented. This research precludes the current invitation to grow sponges for medicinal compounds on a dozen or more pearl farm sites in Indonesia. #MckennaAcademy #espd55 #ZacharyKulberg #MarineSponges
