Abstract:
ObjectiveTo study the chemical constituents of Bidens pilosa and the in vitro antiproliferative activity of some compounds against gastric cancer cells. MethodsThe chemical constituents were isolated and purified by methods such as silica gel column chromatography, preparative thin layer chromatography, medium pressure preparation chromatography, semi-preparative high performance liquid chromatography(HPLC) and recrystallization, their structures were identified on the basis of physicochemical properties, spectral data and circular dichroism spectra. Thiazole blue(MTT) assay was used to determine the in vitro inhibitory activityies of some isolated compounds against human gastric cancer SGC-7901 cells, and molecular docking was used to predict their potential targets. ResultsTwenty-five compounds were isolated from the petroleum ether fraction of B. pilosa and identified as bidpillignan A(1), 5α, 8α-epidioxy-(22E, 24R)-ergosta-6, 22-diene-3β-ol(2), 3β-hydroxysitost-5-en-7-one(3), (20R)-6β-hydroxystigmasta-4, 22-dien-3-one(4), 3β-hydroxylstigmasta-5, 22-dien-7-one(5), (22E, 24S)-24-methyl-5α-choleata-7, 22-diene-3β, 5α, 6β-triol(6), stigamast-5-ene-3β, 7α-diol(7), stigmast-5, 22-diene-3β, 7α-diol(8), 7β-hydroxysitosterol(9), stigmasterol(10), artabotrol(11), cosmosoic acid(12), ent-4(15)-eudesmene-1β, 6α-diol(13), clovandiol(14), 1H-indole-3-carboxaldehyde(15), 6, 7-dimethoxycoumarin(16), 3', 4'-dimethoxyquercetin(17), 8, 8'-bis-(dihydroconiferyl)-diferuloylate(18), hydroxydihydrobovolide(19), 2-deacetyl-11β, 13-dihydroxyxanthinin(20), loliolide(21), pubescone(22), (+)-dehydrovomifoliol(23), 2, 3-dihydroxypropyl palmitate(24) and n-hexadecane acid(25). Among them, compound 1 was a new compound, compounds 3-9, 11-12, 18-20, 22-23 were first isolated from Bidens genus plants, and compounds 13 and 14 were isolated from this plant for the first time. Compounds 17 and 18 showed good in vitro proliferation inhibitory activities against SGC-7901 cells with the half inhibitory concentrations(IC50) of 3.11, 7.22 μmol·L-1, respectively. Molecular docking results showed that the potential targets of the two exerting anti-gastric cancer activity might be vascular endothelial growth factor receptor 2(VEGFR2) and poly(adenosine diphosphate-ribose) polymerase 7(PARP7). ConclusionOne new compound, 14 genus first compounds, and 2 species first compounds were isolated from B. pilosa, among which compounds 17 and 18 processed anti-gastric cancer cell proliferation activity in vitro, and the targets may be VEGFR2 and PARP7.
