Hydroperoxides derived from marine sources: origin and biological activities

Area of Science:

• Marine Natural Products Chemistry
• Biologically Active Compounds
• Pharmacology

Background:

• Hydroperoxides are a class of naturally occurring marine metabolites characterized by the R-O-O-H functional group.
• These compounds are produced by a variety of marine organisms, including bacteria, fungi, algae, and invertebrates.

Purpose of the Study:

• To review and summarize studies on over 80 hydroperoxides isolated from marine sources.
• To highlight the biological activities, particularly antineoplastic, anti-inflammatory, and antiprotozoal properties, of these marine hydroperoxides.

Main Methods:

• Literature review of scientific studies focusing on marine hydroperoxides.
• Analysis of reported biological activities and isolation sources of hydroperoxides.
• Assessment of confidence levels associated with reported bioactivities.

Main Results:

• Hydroperoxides from red, brown, and green algae demonstrated high antineoplastic, anti-inflammatory, and antiprotozoal activity (73-94% confidence).
• Soft coral-derived hydroperoxides exhibited significant antineoplastic and antiprotozoal activity (81-92% confidence).
• Hydroperoxides from sea sponges, mollusks, and other invertebrates showed notable antineoplastic and antiprotozoal (Plasmodium) activity (80-90% confidence).

Conclusions:

• Marine hydroperoxides represent a promising class of natural products with potent bioactivities.
• Algae and marine invertebrates are rich sources of hydroperoxides with significant therapeutic potential, particularly for cancer and protozoal infections.
