Comparing CPDB and Lhasa TD50 values in the Lhasa Carcinogenicity Database
For many years the Carcinogenic Potency Database (CPDB)¹, created by Lois Gold and her team, was an important source of long-term carcinogenicity study data. However, as the database had stopped being updated from 2007, Lhasa moved to safeguard the data by providing ongoing access through a freely available interface; the Lhasa Carcinogenicity Database (LCDB)². The LCDB was released in 2016 and has since been updated with additional data from the National Toxicology Program (NTP)³, increasing the data set to 7,745 studies covering 1,726 chemical substances. A recent update has also facilitated greater ease of access by enabling substructure and similarity-based structure queries.
