Here, we examined the in vitro and in vivo anti-angiogenesis and anti-tumor activities of PE, a new marine-derived compound. Inhibition of angiogenesis was assessed in vitro using proliferation, migration, adhesion, tube-formation and apoptosis assays in PE-treated HMECs and HUVECs. In vivo, CAM assays were used to assess inhibition effect of PE on(More)

A method with tandem high performance liquid chromatography (HPLC) and Q-Tof mass spectrometry (MS) has been established for the qualitative assay of bryostatins in Bugula neritina extracts. Ten bryostatins were well separated on a Polaris C18-5 column (4.6 mm i.d. x 200 mm, 5 microm) with methanol and water (80:20, v/v) as mobile phase. The bryostatins(More)
