The leaves and roots of Rhazya stricta (Apocynaceae) yielded four indole alkaloids. Three of these isolated, vallesiachotamine (1), sewarine (3) and tetrahydrosecamine (4), displayed cytotoxic activity; polyneuridine (2) was not reported previously from this species. Tetrahydrosecaminediol (5), its acetate 6, and didemethoxycarbonyl-tetrahydrosecamine (7) were prepared from tetrahydrosecamine (4) by chemical reactions. The diol 5 was highly cytotoxic.
夹竹桃科植物沙漠玫瑰(Rhazya stricta)的叶和根产生了四种吲哚生物碱。分离得到的其中三种,即瓦莱西乔胺(1)、苏瓦林(3)和四氢南美粟碱(4),具有细胞毒性活性;多神经氨酸(2)此前未在该物种中报道过。四氢南美粟二醇(5)、其乙酸酯6和二去甲氧基羰基 - 四氢南美粟碱(7)通过化学反应由四氢南美粟碱(4)制备而成。二醇5具有高度细胞毒性。
