          <dc:description>&lt;p dir="ltr"&gt;Pre-built SQLite reference database for AILSA (AI + LSD + Agents), an AI-agent system for computer-assisted structure elucidation (CASE) of organic natural products from NMR spectra.&lt;/p&gt;&lt;p dir="ltr"&gt;AILSA is built on the LSD structure generator by Jean-Marc Nuzillard (Université de Reims Champagne-Ardenne).&lt;/p&gt;&lt;p dir="ltr"&gt;Contents: 928,443 compounds (COCONUT: 895,099 natural products with predicted 13C shifts;&lt;/p&gt;&lt;p dir="ltr"&gt;NMRShiftDB: 33,344 compounds with experimental 13C shifts), 111,493 unique molecular formulas, 7.9 million HOSE-code statistics. One file serves both dereplication and 13C prediction.&lt;/p&gt;&lt;p dir="ltr"&gt;Data source: the 13C shifts of the 895,099 COCONUT natural products are predicted, not measured, the 33,344 NMRShiftDB compounds carry experimental 13C shifts.&lt;/p&gt;&lt;p dir="ltr"&gt;COCONUT 13C shifts: from J.-M. Nuzillard, Zenodo, doi:10.5281/zenodo.6561449, CC BY 4.0&lt;/p&gt;&lt;p dir="ltr"&gt;(https://doi.org/10.5281/zenodo.6561449).&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;&lt;p dir="ltr"&gt;Usage: install AILSA (https://github.com/steinbeck/ailsa), run "ailsa database download" - it fetches this file and installs it as data/reference/ailsa-derep.db - and check it with "ailsa database info".
