Experimental chemotherapy group is working in the field of in vitro and in vivo biological screening of novel compounds. Our aim is to find and utilize the most appropriate models for screening of compounds in the purpose to perform structure-activity relationship studies and to obtain more profound data about the possible mechanism of action. In twenty-year period the Experimental group of chemotherapy formed a large collection of various malignant and normal cell lines that are used in search of novel anti-cancer agents.
