Eighteen previously undescribed alkaloids, tishaviolamines A-J, including eight pairs of enantiomers, together with two known benzylisoquinoline alkaloids, (-)-bicuculline and (-)-corlumine, were isolated from Viola tianschanica. Among them, tishaviolamine A-E were demonstrated to possess three types of unpresented skeletons. The structures of these alkaloids were established by comprehensive analyses of the 1D, 2D-NMR and (+)HRESIMS data. The absolute configurations of enantiomers were determined by comparing their calculated ECD spectra with the experimental ones. The menin-mixed lineage leukemia 1 protein-protein interaction inhibitory effect of the isolated compounds were also measured.
从天山堇菜中分离出18种以前未描述过的生物碱,即铁沙维胺A-J,包括8对对映体,以及两种已知的苄基异喹啉生物碱,(-)-荷包牡丹碱和(-)-柯鲁明。其中,铁沙维胺A-E被证明具有三种未呈现的骨架类型。通过对一维、二维核磁共振和(+)高分辨电喷雾电离质谱数据的综合分析确定了这些生物碱的结构。通过将计算得到的电子圆二色谱与实验数据进行比较,确定了对映体的绝对构型。还测定了分离得到的化合物对脑膜混合谱系白血病1蛋白-蛋白相互作用的抑制作用。
