Ecdybase presents biological, chemical, structural, spectroscopic (UV, IR, MS, NMR) and chromatographic data about natural ecdysteroids together with selected relevant references.

Since 2021, there are also various structural descriptors (IUPAC name, canonical and isomeric SMILES, InChi and InChiKey, CAS-Registry Number and PubChem CID) with relevant links to PubChem, ChemSpider and CemIDPlus included in the datasheet of each ecdysteroid. It is additionally possible to obtain a 3-dimensional view of the molecule via on the '3D' button included in the isomeric SMILES box. In the 'Access Data' Section, a list of calculated physico-chemical data for each of the analogues is now also provided.

Case-insensitive search for compounds by name or partial name (a string of at least 3 characters) is available, as well as search by molecular weight, by molecular formula CnxHnyOnz (or selectively by the number of elements Cnx/Onz), and by occurrence in biological sources). Search is also available by the name of author (selected from an available list of quoted authors), and by the year of first record.

The present update of the Ecdybase includes also data on biological activities of ecdysteroids, and also a catalogue of commercial products containing ecdysteroids, with direct links to the homepages of the relevant producers. Attached is also a comprehensive compilation of literary reports for the presence of ecdysteroids in various natural sources.
