A database of 32,000 natural compounds from micro-organisms and higher fungi. It includes descriptive data (molecular formula and mass, elemental composition, CAS registry number); physico-chemical data (melting point, optical rotation); spectroscopic data (UV, 13C-NMR, IR and mass spectra); biological data and more.

"Antibase 2006" is a comprehensive database of 32,000 natural compounds from micro-organisms and higher fungi. The data in "AntiBase" have been collected from the primary and secondary literature and then carefully checked and validated. "AntiBase" includes descriptive data (molecular formula and mass, elemental composition, CAS registry number); physico-chemical data (melting point, optical rotation); spectroscopic data (UV, 13C-NMR, IR and mass spectra); biological data (pharmacological activity, toxicity); and, information on origin and isolation and a summary of literature sources. A unique feature of "AntiBase" is the use of predicted 13C-NMR spectra for those compounds where no measured spectra are available. These spectra have been produced using the spectrum prediction program SpecInfo. Calculated high resolution molecular masses are included in the new update. "AntiBase 2006 SC" is available in the SciDex database format. SciDex is delivered together with the data.
