  title={Metachromins J and K, New Sesquiterpenoids from Marine Sponge Spongia Species},
  author={Jun’ichi Kobayashi and Yohei Takahashi and Masashi Tsuda and Jane Fromont},
Two new cytotoxic sesquiterpenoids, metachromins J (1) and K (2), have been isolated from an Okinawan marine sponge Spongia sp. (SS-1037). The structures of 1 and 2 were elucidated on the basis of the spectroscopic data. 
Metachromins R--T, new sesquiterpenoids from marine sponge Spongia sp.
Three new sesquiterpenoids, metachromins R--T (1--3), have been isolated from an Okinawan marine sponge and showed modest cytotoxicity. Expand
Metachromins L–Q, new sesquiterpenoid quinones with an amino acid residue from sponge Spongia sp.
Abstract Six new sesquiterpenoid quinones with an amino acid residue, metachromins L–Q (1–6), have been isolated from an Okinawan marine sponge Spongia sp. The structures and stereochemistry of 1–6Expand
Metachromins X and Y from a marine sponge Spongia sp. and their effects on cell cycle progression.
New sesquiterpene quinones, metachromins X (1) and Y (2), together with the known metachromins C (3), J (4), and T (5), were isolated as inhibitors of cell cycle progression in the HeLa/Fucci2 cells.Expand
Metachromins U-W: cytotoxic merosesquiterpenoids from an Australian specimen of the sponge Thorecta reticulata.
Three new merosesquiterpenoids, metachromins U, V, and W (1-3), were isolated from a specimen of the marine sponge Thorecta reticulata collected off Hunter Island, Tasmania, Australia. Structures ofExpand
Anhydrocochlioquinone A, a new antitumor compound from Bipolaris oryzae
