Two new neolignans from Patrinia scabra with potent cytotoxic activity against HeLa and MNK-45 cells.[Pubmed: 23737105]

Two new neolignans, patrineolignan A (1) and patrineolignan B (2), together with seven known lignans, were isolated from the 90 % aqueous EtOH extract of the roots of Patrinia scabra. Their structures were elucidated on the basis of spectroscopic data (HRESIMS, IR, 1D and 2D NMR) and comparison with literature data. The two new neolignans were evaluated in vitro for cytotoxic properties against human cervical carcinoma HeLa cell line and gastric carcinoma MNK-45 cell line using the microculture tetrazolium assay, and both 1 and 2 exhibited strongly cytotoxic activity against the two tumor cell lines.

Cytotoxic iridoids from the roots of Patrinia scabra.[Pubmed: 23002924]

Six new iridoid glucosides, patriridosides D-I (1-6), and one new iridoid, scabrol A (7), along with 12 known non-glycosidic and glycosidic iridoids (8-19), have been isolated from an ethanolic extract of the roots of Patrinia scabra. The cytotoxic activity of the isolated compounds against human cervical carcinoma HeLa cells and gastric carcinoma MNK-45 cells was evaluated using the MTT assay. Compounds 1, 4-6, 8, and 18 showed cytotoxic activities against the MNK-45 cell line with respective IC₅₀ values of 15.6, 8.7, 9.4, 30.9, 23.8, and 11.2 μM, while only compound 10 showed cytotoxicity against the HeLa cell line, with an IC₅₀ value of 24.5 μM.

Anti-tumor activity of polysaccharides isolated from Patrinia scabra Bunge on U14 cervical carcinoma bearing mice.[Pubmed: 19885953]

The aim of our study was to investigate the effect of Patrinia scabra Bunge polysaccharide (PSB-P2) on cervical cancer cell (U14)-bearing mice. The tumor weight of mice treated with PSB-P2 (40, 80 mg/kg b.w.) was significantly lower than that of the control group and serum lactate dehydrogenase (LDH) activity was decreased, while serum alkaline phosphatase (AKP) level was only changed slightly. Meanwhile, the number of apoptotic tumor cells was significantly increased in the mice by the treatment of PSB-P2 (40, 80 mg/kg b.w.). At the same time, cell cycle analysis showed the accumulation of tumor cells in the G0/G1 phase and a relative decrease in the S phase. On the other hand, using the reverse transcription-polymerase chain reaction (RT-PCR) assay, PSB-P2 (40, 80 mg/kg b.w.) showed the up-regulation of p53 and Bax, and significant inhibition of Bcl-2 in tumor tissues. It suggests a possible mechanism of the inhibitory effect of PSB-P2 on tumor growth.
