Toxicity studies 1

Task 43 Selected compounds will be subjected first to in silico computational analysis for possible metabolic byproducts generated by plants or microorganisms Task 42 will provide information about photochemical byproducts All resulting molecules will be screened for possible human toxicity using appropriate QSAR models readacross software and experimental approaches Endpoints addressed will comprise ADME cytotoxicity genotoxicity carcinogenicity as well as allergenic and phototoxic potential Suspected toxins will then be selected for OECD guidelinecompliant in vitro analysis for genotoxicity Ames test micronucleus assay and phototoxicity 3T3 phototoxicity assay BfR
