New antibiotics, which have been named Eudistomins, have been obtained from marine organisms. These compounds, which can have anti-viral, as well as anti-bacteria and anti-tumour activity in some cases, are, chemically, derivatives of 5H-pyrido[3,4-b]indole.
New and exceptionally potent antineoplastic agents denominated Bryostatin 9, Bryostatin 10, Bryostatin 11, Bryostatin 12 and Bryostatin 13 have been isolated from the marine animal Bugula neritina (Linneaeus) (Bryozoan phylum) and the structures identified. Meaningful antineoplastic activity is found for each.
