Inhibitory proteas jako nástroj: Návrh, syntéza a testování inhibitorů HIV proteasy a GCPII

Schimer, Jiří

This dissertation thesis focuses on creating tools for the analysis and potential therapeutic intervention in the biological processes regulated by proteolysis. I focus on two important proteolytic enzymes: HIV-1 protease, which is indispensable for the polyprotein processing of the nascent virus and thus for the development of infectious viral particle, and glutamate carboxypeptidase II, a tumor marker and a neuropeptidase from the prostate and central nervous system. Rational design of inhibitors of these therapeutically relevant enzymes serves two purposes: firstly, protease inhibitors were shown to be powerful drugs (HIV protease is in fact the example of successful drug development driven by structural biology). Secondly, and in the context of this thesis perhaps more importantly, inhibitors of medicinally relevant proteases might serve as tools for the elucidation of basic biological questions concerning regulation, timing and spatiotemporal control of such key processes as virus maturation or cancer development. The experimental work described in this thesis summarizes my results in both these areas. Human Immunodeficiency Virus Protease Human immunodeficiency virus (HIV), a causative agent of AIDS, has been estimated to kill close to 40 million people during the past four decades with 1.5...
