Squamocin is one of the annonaceous acetogenins and has been reported to have anticancer activity. Squamocin was found to inhibit the growth of K562 cells in a time- and dose-dependent manner. Cell cycle analysis showed G2/M phase arrest in K562 cells following 24 h exposure to squamocin. During the
OBJECTIVE
To investigate the mechanism of apoptosis of HL60 cells induced by the annonaceous acetogenin, squamocin.
METHODS
Induction of apoptosis was determined through Hoechst33258 dye staining and DNA agarose gel electrophoresis. Expression of the proteins was detected using Western blot
Annonaceous acetogenins have potent antitumor effect in vitro and in vivo. Squamocin is one of the annonaceous acetogenins and has been reported to have antiproliferative effect on cancer cells. Our results from this study showed that squamocin inhibited proliferation of HL-60 cells with IC50 value
Several glycosyl derivatives of squamocin (1) have been synthesized by glycosylation under Lewis acid catalysis with two different 1-O-acetyl sugars. Separation of these compounds has been achieved by HPLC and centrifugal partition chromatography (CPC). A detailed NMR, ESIMS, and LSIMS study allowed
