Myxobacteria are unique gram-negative bacteria characterized by the gliding nature and forming fruiting bodies upon starvation. They were not yet intensively studied because of the difficulties in their isolation and cultivation. However, myxobacteria have recently been recognized as a new and rich source of secondary metabolites which produce novel lead compounds, such as well known anticancer compounds, epothilons.1,2 In the course of our continuing search for novel secondary metabolites from myxobacteria, the myxobacterium Sorangium cellulosum JW1059 was found to produce a new indole alkaloid, named soraphinol A (1), along with a known compound kurasoin A (2).3 Isolation and culture of the producing organism, S. cellulosum JW1059 were carried out by a general procedure that has been described elsewhere.4 We describe here the isolation and structure elucidation of new metabolite by a combination ofNMR techniques.
