The LOTUS Initiative for Open Natural Products Research: Knowledge Management through Wikidata

Abstract: As contemporary bioinformatic and chemoinformatic capabilities are reshaping natural products research, major benefits could result from an open database of referenced structure-organism pairs. Those pairs allow the identification of distinct molecular structures found as components of heterogeneous chemical matrices originating from living organisms. Current databases with such information suffer from paywall restrictions, limited taxonomic scope, poorly standardized fields, and lack of interoperability. To e… Show more

“…A minimum intensity threshold was then used to automatically collect positive 13 To create a DB of molecules and their δ C that can be used by MixONat, the first step is to gather the structures of the compounds of interest (e.g., NPs previously identified in a genus or a botanical family). The easiest way consists of downloading them from various DBs accessible through subscription (e.g., SciFinder [28], Dictionary of Natural Products [20]) or from freely available ones (e.g., KNApSAcK [31], Universal Natural Products Database [37], LOTUS [38,39]). Once the individual files of each molecule (.mol,.…”

“…For example, the COCONUT database has recently been leveraged to create a resource (called LOTUS) directly linking natural product chemical structures to freely available articles describing the characterization and biological evaluation of the compounds. 8 In another recent report, the Natural Products Atlas was queried by Robey et al 9 Our eld is likely nearing a tipping point where researchers will begin to rely more on open-access databases and less on historical subscription-only compendia of natural product structures such as MarinLit, AntiBase, and the Dictionary of Natural Products. At the present time, however, the open access databases are still not comprehensive enough to entirely replace the subscription-based sources, and the existence of multiple different platforms for storing chemical structures, each with different coverage and linked to different types of information, creates a great deal of confusion among researchers.…”

“…Yet although this database has high potential (e.g. Waagmeester et al 2020;Rutz et al 2021), it currently does not systematically cover the different scientific disciplines. As preliminary work, we thus included >26,000 publications of the field of invasion science in Wikidata, where they can be explored in a domain-general way through tools like Scholia (https://tools.wmflabs.org/scholia/topic/Q42985020; Nielsen et al 2017;Rasberry et al 2019).…”
