| Abstract: | DZ2002 and its related stereoisomers were efficiently synthesized. The optical data of (R)- and (S)-DZ2002 were disclosed here for the first time. Their inhibitory potency was evaluated on SAHase and MLR assay in the mean time. In accordance with respective inhibitory potency of SAHase, the immunosuppressive potency order was demonstrated as (S)-DZ2002>(Rac)-DZ2002>(R)-DZ2002>(Keto)-DZ2002. These results indicate (S)-configuration of 2-chiral center in DZ2002 is important for binding with SAHase. |
