Inoma PANC-1 and BxPC3 cell lines had been purchased in the Cell Bank of the Chinese Academy of Science (Shanghai, China) and cultured in DMEM (Corning, Beijing, China) supplemented with ten FBS (Sigma, Shanghai, China) and 1 Penicillin treptomycin (Sigma, Shanghai, China) at 37 C with 5 CO2 . Within the exponential phase from the growth, cells have been plated onto 96-well plates at a concentration of 8000 cells/well for 24 h. Compounds 1 have been ready to numerous concentrations (80, 40, 20, 10, 5, 2.5, 1.25, and 0.625 in medium containing significantly less than 0.1 DMSO) and incubated in 96-well plates (every single concentration in six-fold wells) for 72 h. Gemcitabine (Gem, Meilunbio, 98 , Dalian, China) was presented because the positive handle. Cell viability was determined according to reported assay techniques utilizing the commercial CCK8 kit (Elabscience, Wuhan, China) [29]. The optical density (OD) of each and every well was measured with an AMR-100 microplate reader at 450 nm (Allsheng Corporation, Hangzhou, China). Cytotoxicity emerged because the value from the drug concentration at the inhibition of cell growth by 50 (IC50 ). 4. Conclusions This study afforded 10 compounds from the rhizomes of Paris mairei, which includes five new spirostane saponins. None from the new compounds exhibited cytotoxicity against PANC-1 and BxPC3 pancreatic cell lines, implying that the polyglucosides at 1-hydroxy in spirostane saponins may substantially decreased the activities of antitumor.Supplementary Materials: The following are readily available on line, Figures S1 55: NMR (1D and 2D) and MS spectra of compounds 1.
