What is a Structure Activity Relationship (SAR)?
SAR is a technique used by chemists, biologists, and other scientists to correlate the biological activity of a chemical to its structure. When performing SAR analysis, a scientist will group chemical compounds by structural characteristics such as shape, size, chemical arrangement and distribution of functional groups, and analyzes the contribution of each factor to biological activities. Other considerations include the conditions under which humans may be exposed to the chemical in question. What is an expert system? An expert system is a computer program that mimics the judgment of experts by following sets of knowledge rules that are based on studies of how chemicals cause cancer in animals and humans. An expert system, like OncoLogic™, asks for chemical and use information from the user and following the knowledge rules incorporated into the system, uses the responses to construct an estimation of the most likely results. What are the chemical classes evaluated by OncoLogic™? Cur
