Chemosensitive profiling platform for systematic chemosensitive profiling of libraries of small molecules on the panel of cell lines of various histological origins. This service provides a unique complex information to chemist users about the potential clinical value of their compound library. The collection of cell lines represents cellular models for various types of cancers and is conceived to cover the most diverse types of tissues. Furthermore, each tissue is represented by one or more cell lines, according to the frequency that this type of oncological diseases contributes to the world's total cancer mortality. Systematic profiling of compound libraries provides information about the phenotypic changes, cytotoxic and anti-proliferative properties of compounds in each cell line. The association of obtained activity profiles with genetic background and specifically accumulated mutations in respective cell lines allows to identify specific pathways/processes/receptors utilised by small molecules.
