Outline of Final Research Achievements

Our aim of this study was to synthesize new low-molecular compound which has pharmacological effects of both dichloroacetate and acetyl-carnitine and to analyze its effect of organ protection.
We synthesized basic molecular platform in 2012 and succeeded to produce new compound A which was induced biological equivalent substituent during 2013-2014. The functional recovery rate of reperfused rat heart under isolated heart perfusion system was significantly high of 73±38% in compound A group in comparison with the control group of 14±6%. The structure of the new compound was concealed because this was under pending patent application.
