It should be noted that cyclooroidin (38) could be envisaged as the precursor of the nonimidazole bromopyrrole alkaloids longamides (see below). Two cyclooroidin analogs have been isolated agesamide (39) from Agelas sp. [68] and oxocyclostylidol (40) from Stylissa caribica [69]. This latter compound represents the first pyrrole-imidazole alkaloid that includes an oxidized pyrrole moiety. 

Grube and Kock [47] reported the characterization of oxocyclostylidol (12), an intramolecular cyclized oroidin derivative from the marine sponge, Stylissa caribica.
