also active against human MDA‐MB‐435 melanoma cells. X‐ray structures of the β‐hydroxy ketone product (4a) and the α,β‐unsaturated ketone (4h) were collected, and confirm the syn‐configuration between the carbonyl moiety and the β‐vinylic proton in 4h. X‐ray structures of two 1‐cyclohexylpyrrolidin‐2‐one derivatives were also obtained, and both showed an E‐configuration for the double bond.
设计、合成了两种不同系列的新型查耳酮类似物,一种来源于 1-环己基吡咯烷-2-one,另一种来源于 1-苯并 [f] 色满酮,并评估了对两种鼠癌细胞系的细胞毒性。两种 1-苯并[f] 色满酮类似物 4g 和 4j 对黑色素瘤 B16 和淋巴瘤 L1210 细胞系产生中等毒性,IC50 值在 5 到 6 µM 之间。IC50 值为 3.4 µM,化合物 4g 对人 MDA-MB-435 黑色素瘤细胞也有活性。收集了 β-羟基酮产物 (4a) 和 α,β-不饱和酮 (4h) 的 X 射线结构,并在 4 小时内确认了羰基部分和 β-乙烯基质子之间的顺式构型。还获得了两个 1-环己基吡咯烷-2-one 衍生物的 X 射线结构,并且都显示出双键的 E-构型。
