Why are marine products natural?
Due to the unique environmental conditions and vast territory, marine habitat breeds more abundant biological resources than terrestrial environment. Massive marine biological species provide valuable resources for obtaining a large number of natural products with diverse structure and excellent activity.
Are there any new anticancer drugs from natural sources?
Cancer remains one of the most lethal diseases worldwide. There is an urgent need for new drugs with novel modes of action and thus considerable research has been conducted for new anticancer drugs from natural sources, especially plants, microbes and marine organisms.

What are marine-derived anticancer drugs?
Most of the marine-derived agents are single-celled organisms, ranging from eubacteria through to eukaryotes such as fungi and protists. Once known for production of harmful toxins, the marine blue-green algae are emerging as an important source of anticancer drugs.
