The total synthesis of alkaloids phenanthroindolizidine 1a, tylophorine 1b, and phenanthroquinolizidine 1c, has been achieved in 46%, 49%, and 42% overall yield, respectively, starting from the corresponding phenanthrene-9-carboxaldehyde. Compound exhibited potent inhibition activity in three human cancer cell lines, with IC(50) values ranging from 104 to 130 nM. The structure-activity relations of
从相应的菲-9甲醛开始,分别以46%,49%和42%的总收率实现了生物碱菲咯啉吲哚1a,酪氨酸1b和菲喹喹啉1c的总合成。该化合物在三种人类癌细胞系中表现出强大的抑制活性,IC(50)值范围从104到130 nM。还描述了这些生物碱及其某些合成中间体对这三种细胞系的构效关系。
