    ZJU-6, a novel derivative of Erianin, shows potent anti-tubulin polymerisation and anti-angiogenic activities.[Pubmed: 21997795]
    ZJU-6 was designed to enhance anti-angiogenesis and anti-tumour activity of its parent compound Erianin, a clinic anti-tumour agent. This study investigated the detailed biological mechanism of ZJU-6 in comparison with that of Erianin. Both ZJU-6 and Erianin substantially reduced cell viability and induced apoptosis in human cancer cell lines. Profound G2/M cell arrest was observed 24 h after treatment of MCF-7 cells with ZJU-6 (≥ 2.5 μM) or Erianin (≥ 0.1 μM); being consistent with mitotic collapse. 0.5 μM of Erianin or ZJU-6 failed to stabilise tubulin. Pre-G1 MCF-7 cell accumulating 24 h post treatment indicated apoptosis. Caspase-3 activity, PARP cleavage and Annexin V + ve /PI -ve populations correlate the apoptotic destiny of cells exposed to either ZJU-6 or Erianin. Furthermore ZJU-6 showed potent anti-angiogenetic property and demonstrated radical scavenging capacity. Due to its potent anti-proliferative, pro-apoptotic and anti-angiogenic activities ZJU-6 is an attractive chemotherapeutic agent to be developed.

    Liquid chromatographic-mass spectrometry analysis and pharmacokinetic studies of erianin for intravenous injection in dogs.[Pubmed: 19402345]
    The purpose of the present study was to examine the pharmacokinetic characteristics of Erianin (2-methoxy-5-[2-(3,4,5-trimethoxyphenyl)-ethyl]-phenol, CAS 95041-90-0), a nature product extracted from Dendrobium chrysotoxum, having notable antitumour activity, after intravenous injection of Erianin fat emulsion to beagle dogs. An HPLC-MS method was developed to analyze the Erianin levels in dog plasma and validated in a pharmacokinetic study. Plasma profiles were obtained after intravenous injection of Erianin fat emulsion at the doses 7.5, 15 and 30 mg/kg. The elimination half-life (t(1/2)) values for Erianin were estimated to be 1.41+/- 0.31, 1.66 +/- 0.19, 1.60 0.28 h, while the mean area under concentration-time curve (AUC(0-infinity)) values were 1021.3 +/- 373.7, 2305.1 +/- 597.0 and 3952.1 +/- 378.2 ng x h/ml, respectively. In conclusion, the present observations indicated that Erianin plasma concentrations were clearly dose-proportional for the dose range studied. There was no gender difference in pharmacokinetics for Erianin in male and female dogs.

    Erianin induces a JNK/SAPK-dependent metabolic inhibition in human umbilical vein endothelial cells.[Pubmed: 15113050]
    BACKGROUND: Erianin is a natural product derived from Dendrobium chrysotoxum, with promising antitumor activity. MATERIALS AND METHODS: To evaluate the metabolic effect of Erianin, a cytosensor assay for acidification rate, MTT assay, measurement of lactate, glucose and ATP were performed in human umbilical vein endothelial cells (HUVECs) exposed to 1-100 nM Erianin. JNK/SAPK activity was detected by Western blot. RESULTS: Twelve- or 24- hour incubation with Erianin induced a dose-dependent metabolic inhibition, as indicated by reduced acidification rate and cell viability, with an endothelium-selectivity. Erianin caused decreases in lactate production, glucose consumption and intracellular ATP level. Pretreatment with the JNK/SAPK inhibitor SP600125 significantly abolished these inhibitory responses, and especially restored the Erianin-induced decreases in ATP and the Erianin-induced phosphorylation of JNK/SAPK with dose- and time- dependence. CONCLUSION: Erianin inhibited endothelial metabolism in a JNK/SAPK-dependent manner. This mechanism may be involved in the potential antitumnor and antiangiogenic actions of Erianin.

    Erianin induces apoptosis in human leukemia HL-60 cells.[Pubmed: 11749794]
    AIM: To investigate the effect of Erianin on human HL-60 cell line and explore its mechanism of apoptosis in vitro. METHODS: Inhibition of proliferation was measured with colorimetric MTT assay. The morphologic changes were observed by fluorescence and electron microscopes. DNA fragmentation was visualized by agarose gel electrophoresis, and the DNA degradation was determined by flow cytometry. Immunohistochemical analysis was used to identify the expression of bcl-2 and bax genes. RESULTS: The growth of human HL-60 cells was significantly inhibited by Erianin 20-81.9 nmol/L during 72 h treatment (P < 0.01). The IC50 value was 38 nmol/L after a 24-h exposure to Erianin, while that of vincristine, the positive control, was 101 nmol/L. The typical morphologic changes were observed and the nuclear DNA fragmentation exhibited "ladder" pattern. The cell cycle of HL-60 cells was arrested in G2/M phase, and expression of bcl-2 gene was decreased while that of bax was increased. CONCLUSION: Erianin showed potent inhibitory activity on the proliferation of HL-60 cells. The inhibition might be relative to the apoptosis induced by Erianin and the altered expression of bcl-2 and bax genes in HL-60 cells.

    In vivo and in vitro evaluation of erianin, a novel anti-angiogenic agent.[Pubmed: 15196540]
    This study evaluated the anti-angiogenic activities of Erianin in vivo and in vitro. Erianin, a natural product from Dendrobium chrysotoxum, caused moderate growth delay in xenografted human hepatoma Bel7402 and melanoma A375 and induced significant vascular shutdown within 4 h of administering 100 mg/kg of the drug. Erianin also displayed potent anti-angiogenic activities in vitro: it abrogated spontaneous or basic fibroblast growth factor-induced neovascularisation in chick embryo; it inhibited proliferation of human umbilical vein endothelial cells (EC(50) 34.1+/-12.7 nM), disrupted endothelial tube formation, and abolished migration across collagen and adhesion to fibronectin. Erianin also exerted selective inhibition toward endothelial cells, and quiescent endothelium showed more resistance than in proliferative and tumour conditions. In a cytoskeletal study, Erianin depolymerised both F-actin and beta-tubulin, more significantly in proliferating endothelial cells than in confluent cells. In conclusion, Erianin caused extensive tumour necrosis, growth delay and rapid vascular shutdown in hepatoma and melanoma models; it inhibited angiogenesis in vivo and in vitro and induced endothelial cytoskeletal disorganisation. These findings suggest that Erianin has the therapeutic potential to inhibit angiogenesis in vivo and in vitro.
