SB365, Pulsatilla saponin D, suppresses the growth of gefitinib-resistant NSCLC cells with Met amplification.
Clinical treatment using epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) such as gefitinib or erlotinib has been applied in patients with non-small cell lung cancers (NSCLCs). Unfortunately, acquired drug resistance emerges in these patients due to the amplification of the Met proto-oncogene, which may be a compensatory mechanism of NSCLCs against EGFR inhibition. To ove...
متن کاملPulsatilla saponin D: the antitumor principle from Pulsatilla koreana.
By bioassay-guided separation, an already known saponin, Pulsatilla saponin D was isolated from the root of Pulsatilla koreana Nakai as a antitumor component when evaluated by in vivo antitumor activity as well as in vitro cytotoxic activity test. It showed potent inhibition rate of tumor growth (IR, 82%) at the dose of 6.4 mg/kg on the BDF1 mice bearing LLC cells.
متن کاملSB365, Pulsatilla saponin D suppresses proliferation and induces apoptosis of pancreatic cancer cells.
Pulsatilla koreana has been used as a traditional medicine for the treatment of various diseases. The purpose of this study was to determine whether SB365, Pulsatilla saponin D isolated from the root of Pulsatilla koreana inhibits the progression of pancreatic cancer. We found that SB365 strongly suppressed the growth and proliferation of 5 human pancreatic cancer cell lines (MIAPaCa-2, BXPC-3,...
متن کاملAntiangiogenic and antitumor activities of IL-27.
IL-27 is a novel IL-6/IL-12 family cytokine playing an important role in the early regulation of Th1 responses. We have recently demonstrated that IL-27 has potent antitumor activity, which is mainly mediated through CD8(+) T cells, against highly immunogenic murine colon carcinoma. In this study, we further evaluated the antitumor and antiangiogenic activities of IL-27, using poorly immunogeni...
متن کاملAntiangiogenic activities and cisplatin-combined antitumor activities of BPR0L075.
BACKGROUND Antimitotic tubulin-binding BPR0L075 is structurally analogous to the vascular-disrupting combretastatin A-4. MATERIALS AND METHODS In vitro/in vivo models of endothelial cells cultures, Matrigel plug assay, tumor-bearing nude mice, and murine leukemia cells-inoculated mice were utilized to evaluate BPR0L075 for antiangiogenic and antitumoral activity spectra. RESULTS BPR0L075 co...
