New liver intelligence in Instem’s Safety Intelligence Program

The liver is an important indicator of drug toxicity.  It deals with toxins and many medicinal products that pass through the body, and as such, has a high chance of being exposed to drug toxicity.  More than 900 drugs, toxins and herbs are known to cause liver injury1. Hepatic injury is a common reason for drug withdrawal, but can be difficult to detect as many drugs only cause it infrequently2.

The Safety Intelligence Program (SIP) is a knowledgebase of comprehensive intelligence, built from a wide set of public domain sources, around compounds causing adverse effects in tissues, including effects on biomarkers of tissue injury and also molecular mechanisms.

The data in SIP can be accessed via both drug class and chemical structure searches, meaning that drugs with similar structures and other properties can be compared to a drug in development.  This means that potential hepatotoxicity could be detected earlier in the drug development process, which could potentially lead to large savings.

Cheminformatics Breathes New Life Into Legacy Data

P_Bradley

It has been a privilege to have recently been involved in an exciting new collaboration with Alexander Tropsha and Denis Fourches at the University of North Carolina. The team carried out a cheminformatics analysis of the assertional metadata (AMD) from BioWisdom’s Safety Intelligence Program (SIP), the world’s largest, ever-expanding collection of the known effects of drugs and other chemicals. SIP makes use of BioWisdom’s collection of key concept metadata and Sofia technology, which translates the varied and diverse language used by scientists into a semantically consistent form. The study has provided a fresh new perspective on historic public domain data, bringing together isolated fragments of toxicology information, spanning decades, to provide new insight into drug safety. The resulting article, entitled “Cheminformatics Analysis of Assertions Mined from Literature That Describe Drug-Induced Liver Injury in Different Species”, was published in Chemical Research in Toxicology on December 16, 2009.

Meeting report – DSEC Pre-GLP Safety Strategy

Jane1I attended a virtual conference last week, hosted by the Drug Safety Executive Council (DSEC), on “Pre-GLP Safety Strategy Session: Key Areas to Address When Planning a Pre-GLP Safety Evaluation”. It was an excellent session, very well run with good moderators, and some excellent speakers.
