The Natural Products Atlas is designed to cover all microbially-derived natural products published in the peer-reviewed primary scientific literature. This encompasses bacterial, fungal and cyanobacterial compounds, but does not include compounds from plants, invertebrates or other higher organisms unless these compounds have also been explicitly identified from a microbial source. Compounds from lichens and mushrooms and other higher fungi are included. Compounds from marine macro algae and diatoms are excluded.
