Outline of Final Research Achievements |
Enantiomer, which is relationship between the right hand and the left hand, is known to be difficult to discern and separate them because physical properties are the same. In our previous study, it have been revealed that the tea major compound (-)-epigallocatechin-3-O-gallate (EGCg) captures many substances including caffeine. These results led to the idea that EGCg may be available as a new optical resolving agent for natural products and medicines. Chiral recognition of EGCg is investigated using diketopiperazine cyclo(L-Pro-Gly), cyclo(D-Pro-Gly) and sympathetic β-receptor blocker (R)-propranolol, (S)-propranolol, and we reveal that EGCg can discern these enantiomers.
