Polymeric delivery systems for immunooncotherapy
 Šírová, Kateřina ; Etrych, Tomáš (advisor) ; Konvalinka, Jan (referee)
Oncological diseases are among the most common causes of death in developed countries and for some of them, current medicine still does not have satisfactory results. Designing of polymer therapeutics characterized by high molecular weight and controlled drug delivery is one of the perspective ways of development of new therapeutic protocols. Nowadays, scientists also focus on the research on anticancer immunological mechanisms and their potential use in cancer therapy. Constitutive activation of signal transducer and activator of transcription 3 (STAT3) has been described in many types of malignancies. The function of STAT3 is very complex, the aberrant activation in cells of tumor microenvironment is related to many predominantly prooncogenic processes. This bachelor thesis is focused on synthesis of peptide inhibitor of STAT3 signaling, phosphopeptide pYLPQTV, and its conjugates with polymer carrier based on N-(2-hydroxypropyl)methacrylamide (HPMA). The inhibitor and the polymeric conjugates have been characterized by several physico-chemical techniques; also, effect on proliferation of cancer cells have been tested in in vitro conditions, which proved slightly cytotoxic activity. A more detailed study and an optimization of methods for in vitro characterization will be necessary to further...
