Abstract:
:The fruit of the white mulberry tree (Morus alba L.) is a multiple fruit with a sweet flavor commonly consumed around the world. Chemical investigation of the fruits led to the isolation of two indole acetic acid derivatives (1 -2) including a new compound, which turned out to be an isolation artifact, 3S-(β-D-glucopyranosyloxy)-2,3-dihydro-2-oxo-1H-indole-3-acetic acid butyl ester (1), along with five known compounds (3 -7). Compounds 2 and 7 were newly identified from mulberry fruit. The new isolation artifact (1) exhibited cytotoxic effect on human cervical cancer Hela cells in a dose-dependent manner. Compound 1 activated caspase-8, caspase-9, and caspase-3, followed by cleavage of PARP, a substrate of caspase-3, in a dose-dependent manner. Simultaneous alterations in protein expression of mitochondrial factors Bax, BID and Bcl-2 were also observed. A comparison between compounds 1 and 2 led to a structure-activity relationship analysis of the cytotoxic effect. These results suggest that compound 1 could be beneficial in human cervical cancer treatment, and provide a theoretical basis for further application of compound 1.
