Abstract: Cisplatin, carboplatin and oxaliplatin are the most widely used platinum-based chemotherapeutical agents yet characterized by severe toxicity and short circulation period in the blood. Approaches to reducing their adverse effects and improving their functional properties include application of (i) ‘non-classical’ platinum drugs and (ii) platinum drugs immobilized in a polymer carrier for targeted delivery. A large number of them reveal potential as promising therapeutic compounds during clinical trials.

Abstract: Information on Pitagoras′2012 prize for science for the period 2009−2011 in the field of chemistry awarded by the Bulgarian Ministry of Education, Youth and Science on 26 June 2012 in Sofia is presented. Brief biographical data of the winner, Professor Ovanes G. Mekenyan, DSc, affiliated at Professor Dr. Asen Zlatarov University of Burgas, Bulgaria, are given. Professor O. G.
