Three highly functionalized pyrroloquinoline alkaloids, batzelline A (1), B (2), and C (3) were isolated from the deep water Bahamas sponge Batzella sp. The structure of 1 was determined by X-ray and those of 2 and 3 deduced by comparison of their spectral data with that of 1 and by chemical transformations.

The structure of batzelline A (1) was determined by X-ray and those of B and C deduced by comparison of their spectral data with that of 1.
