Arglabin derivatives varied at the endo‐ or exo‐cyclic double bond were synthesized and studied in a colorimetric sulforhodamine B assay for their cytotoxicity. Variations on the endocyclic double bond led to compounds of reduced cytotoxicity whereas derivatives from the reaction of the α‐methylene‐γ‐butyrolactone moiety led to compounds of similar or only slightly reduced cytotoxicity but different
合成了内环或外环双键不同的 Arglabin 衍生物,并在比色磺罗丹明 B 试验中研究了它们的细胞毒性。环内双键的变化导致化合物的细胞毒性降低,而来自 α-亚甲基-γ-丁内酯部分反应的衍生物导致细胞毒性相似或仅略微降低但细胞系依赖性不同的化合物。此外,arglabin 是合成愈创木酚内酯树胶素的优良原料。
