MetaPath: an electronic knowledge base for collating, exchanging and analyzing case studies of xenobiotic metabolism.

The MetaPath knowledge base was developed for the purpose of archiving, sharing and analyzing experimental data on metabolism, metabolic pathways and crucial supporting metadata. The MetaPath system grew out of the need to compile and organize the results of metabolism studies into a systematic database to facilitate data comparisons and evaluations. Specialized MetaPath data evaluation tools facilitate the review of pesticide metabolism data submitted for regulatory risk assessments as well as exchange of results of complex analyses used in regulation and research.

Investigating the relationship between in vitro-in vivo genotoxicity: derivation of mechanistic QSAR models for in vivo liver genotoxicity and in vivo bone marrow micronucleus formation which encompass metabolism.

Strategic testing as part of an integrated testing strategy (ITS) to maximize information and avoid the use of animals where possible is fast becoming the norm with the advent of new legislation such as REACH. Genotoxicity is an area where regulatory testing is clearly defined as part of ITS schemes. Under REACH, the specific information requirements depend on the tonnage manufactured or imported.

Quantitative structure-activity relationship modeling of dermatomyositis activity of drug chemicals.

Dermatomyositis (DM) is an idiopathic inflammatory disorder consisting of skin and skeletal muscle involvement. Some drugs induce DM or dermatomyositis-like syndrome (DM-LS), the others provoke polymoysitis (PM) or cause elevation of serum levels of muscle enzymes (SE) or give muscle damage (M). The unexpected adverse reactions to drugs causing myositis are not a solved contemporary problem.
