| 非ポリマーの詳細 | Two enantiomers, QNN and QN8 are produced by reaction of the Michael acceptor compound "2- ...Two enantiomers, QNN and QN8 are produced by reaction of the Michael acceptor compound "2-methylenequinuclidin-3-one" with cysteine or lysine. As such, QNN and QN8 bind covalently to the thiol group of cysteine or amino group of lysine. The chiral definitions of QNN and QN8 bound to Cysteines are reversed to that of the pseudo free ligands. |
