Convolutindole A (2,4,6-tribromo-1,7-dimethoxy-N,N-dimethyltryptamine) is a brominated tryptamine alkaloid that was first identified in 2001 in Amathia Convoluta, a marine bryozoan. Bryozoans are aquatic invertebrates that grow in colonies and may resemble coral.


Convolutamine A is the 2,4,6-tribromo-1,7-dimethoxy derivative of DMT, a hallucinogen that occurs naturally in many plants and animals. Convolutamine A is chemically related to 5-bromo-DMT - A similar molecule that also occurs in many marine invertebrates.

The researchers who discovered the chemical drew specific attention to the methoxy group at the indole 1-position (attached to the nitrogen atom in the pentagonal ring) as being an unknown occurrence in the marine world until recently. 1-methoxyindoles such as Lespedamine also occur in Legumes and the Brassicaceae, the plant family that cabbage and mustard belong to.[clarification needed]

Biological activity[edit]

This chemical was tested for its ability to kill parasitic nematodes, It was found to be more effective than levamisole, a synthetic drug used to kill parasitic worms and to treat colon cancer.
