1. What information does TM-MC 2.0 hold?
TM-MC 2.0 provides information on the chemical compounds of medicinal materials listed in the Korean, Chinese, and Japanese pharmacopoeias. TM-MC 2.0 also includes new information on prescriptions, gene targets, modern diseases, and their associations.
2. How was TM-MC 2.0 constructed?
(1) PubMed articles were searched using the names of medicinal materials listed in the Korean, Chinese, and Japanese pharmacopoeias, and chromatographic articles were filtered with the following words: “chromatograph”, “CCC”, “CEC”, “CMC”, “FPLC”, “GC/MS”, “GC-MS”, “GLC”, “GPC”, “HPLC”, “IMAC”, “LC/MS”, “LC-MS”, “MEEKC”, “MEKC”, “NPLC”, “PGC”, “RPC”, “RPLC”, “RSLC”, “SEC”, “SFC”, “SMBC”, “TLC”, “TMBC”, “UFLC”, and “UPLC”. Then, Korean medicine experts manually extracted the names of the constituent compounds of medicinal materials from the full text of the filtered articles.
(2) All compound names have been identified and de-duplicated, and are given with their corresponding identifiers and pharmacokinetic properties.
(3) Information on targets of chemical compounds and diseases related to the targets was retrieved from STITCH v5.0 and DisGeNET v7.0, respectively.
(4) Prescriptions containing medicinal materials were extracted and curated manually from prescription textbooks and internal medicine textbooks used at Korean medicine universities.
3. How does TM-MC 2.0 differ from other TCM databases?
TM-MC 2.0 has an advantage in that it contains the largest number of identified chemical data of medicinal materials listed in Chinese pharmacopoeia compared to other TCM databases. In recent years, many chromatographic articles have been published on the chemical compounds of medicinal materials in PubMed. Through manual curation of these articles, TM-MC 2.0 contains many new compounds that do not exist in other TCM databases.
Moreover, TM-MC 2.0 includes the largest number of marker compounds listed in the Chinese pharmacopoeia compared to TCMSP 2.3 and TCMID 2.0. This indicates that TM-MC 2.0 provides better information than other TCM databases on the quantity and quality about the chemical compounds of medicinal materials.
