diastereomeric sulfoxides, namely (S(C2)R(C7)R(S))- and (S(C2)R(C7)R(S))-gamma-glutamyl-S-benzylcysteine S-oxides (gamma-glutamyl-petiveriins A and B, respectively). Their structures and absolute configurations have been determined by NMR, MALDI-HRMS, IR and CD spectroscopy, and confirmed by comparison with authentic compounds obtained by synthesis.
三种 γ-谷氨酰二肽已从 Petiveria alliacea L. 根中分离出来。这些二肽包括 (S(C2)R(C7))-γ-谷氨酰-S-苄基半胱氨酸以及两种非对映亚砜,即 (S(C2)R(C7)R(S))- 和 (S(C2)R (C7)R(S))-γ-谷氨酰-S-苄基半胱氨酸 S-氧化物(分别为 γ-谷氨酰-petiveriins A 和 B)。它们的结构和绝对构型已通过 NMR、MALDI-HRMS、IR 和 CD 光谱确定,并通过与合成获得的真实化合物进行比较来确认。
