Study Notes

Marine Organisms and Bioactive Compounds

  • Terpenoids: Found in corals, sponges, green algae, and brown algae, these compounds exhibit anti-inflammatory properties.
  • Sterols: Primarily found in soft corals and serve as a potential source of anti-inflammatory agents.
  • Polyhalogenated Monoterpenes: Derived from red algae, these compounds possess cytotoxic effects.
  • Nucleosides: Sponges produce adenine and cytosine derivatives, which have potential applications in cancer treatment.
  • Polyethers or Polyketides: Compounds like Halichondin B, extracted from sponges, showcase anti-cancer properties.

Marine Organisms and Bioactive Compounds

  • Marine organisms such as corals, sponges, green algae, brown algae, and red algae produce a variety of bioactive compounds.
  • Terpenoids are a class of compounds found in corals, sponges, green algae, and brown algae. They possess anti-inflammatory properties.
  • Sterols are found in soft corals and exhibit various biological activities.
  • Polyhalogenated monoterpenes are produced by red algae and are cytotoxic.
  • Nucleosides, particularly adenine and cytosine derivatives, are isolated from sponges and have potential anti-cancer properties.
  • Polyethers or Polyketides, such as Halichondin B from sponges, are known for their anti-cancer effects.
