goniothalamus walkeri/肺がん

An investigation of the chemical constituents in a dichloromethnae extract of Goniothalamus undulatus root led to the isolation of three known styryl lactones (5-acetoxyisogoniothalamin oxide, O-acetylaltholactone and altholactone), and four known annonaceous acetogenins (annonacin, cis-annonacin,

The ethanolic extract from the stem bark of Goniothalamus marcanii Craib was shown in preliminary brine shrimp lethality data having good cytotoxic activity. Further bioassay guided isolation was done by means of solvent partition, chromatography and precipitation to provide four isolated compounds:

Two new styryl lactones, 9-deoxygoniopypyrone [1] and 7-epi-goniofufurone [3], and a known styryl lactone, goniodiol [5], were isolated from the stem bark of Goniothalamus giganteus. The structures were elucidated by ir, ms, 1H-nmr, 13C-nmr, and 1H-1H COSY spectra; the relative configurations were

Howiinol A (GHM-10) is a kind of phenylethylene pyrone compounds isolated from Goniothalamus howii. By using the techniques of cell growth curve determination, MTT test, soft agar colony assay and experimental therapy of transplantable tumors in mice, it is found that GHM-10 exerts potent inhibitory
