MarinLit is a database dedicated to marine natural products research. The database was established in the 1970s by Professors John Blunt and Murray Munro at the University of Canterbury, New Zealand. It was designed as an in-house system to fulfil the needs of the University of Canterbury Marine Group and has evolved to contain unique searchable features and powerful dereplication tools. The extremely comprehensive range of data contained along with these powerful features makes MarinLit the database of choice for marine natural products researchers.

MarinLit is text and structure searchable. Queries can be built across a number of fields and parameters. Along with comprehensive information on relevant published articles and compounds, MarinLit provides dereplication tools based on experimental and predicted data.
