Recently, we have identified a biphenyl-aryl urea incorporated with salicylaldoxime (BPS-7) as an anti-angiogenesis agent. Herein, we disclosed a series of novel anti-angiogenesis agents with BPS-7 as lead compound through combining diarylureas with N-pyridin-2-ylcyclopropane carboxamide. Several title compounds exhibited simultaneous inhibition effects against three pro-angiogenic RTKs (VEGFR-2, TIE-2 and EphB4). Some of them displayed potent anti-proliferative activity against human vascular endothelial cell (EA...

BACKGROUND: High altitude cerebral edema (HACE) is a fulminant, deadly, and yet still unpredictable brain disease. A new prophylactic treatment for HACE and its predecessor, acute mountain sickness (AMS), needs to be developed without the contraindications or adverse effect profiles of acetazolamide and dexamethasone. Since neovascularization signals are likely key contributors to HACE/AMS, our approach was to examine already existing anti-angiogenic drugs to inhibit potential initiating HACE pathway(s)...

The development of new blood vessels from a pre-existing vasculature (also known as angiogenesis) is required for many physiological processes including embryogenesis and post-natal growth. However, pathological angiogenesis is also a hallmark of cancer and many ischaemic and inflammatory diseases. The pro-angiogenic members of the VEGF family (vascular endothelial growth factor family), VEGF-A, VEGF-B, VEGF-C, VEGF-D and placental growth factor (PlGF), and the related receptors, VEGFR-1, VEGFR-2 and VEGFR-3 have a central and decisive role in angiogenesis...

Ramucirumab is a monoclonal antibody against Vascular Endothelial Growth Factor Receptor-2 (VEGFR-2) approved for the treatment of several solid tumours. As shown in recent trials results, new-onset hypertension is one of the most frequent adverse events associated with ramucirumab therapy. Recent studies looked at the quantification of the risk of hypertension in patients receiving other anti-angiogenesis medications. We conducted a meta-analysis of randomized clinical trials with the aim to investigate the incidence and quantify the risk of new-onset hypertension of any grade in patients treated with ramucirumab...

The treatment of triple negative breast cancer (TNBC) is a significant challenge to cancer research. The lack of hormone receptors limits the treatment options available to patients with this diagnosis, forcing them to endure prolonged radiation and chemotherapy. Anti-angiogenesis is a chemotherapeutic strategy that targets the vasculature of tumors. Combretastatin A-4 (CA-4) is a well-known vasculature-disrupting agent, which has been shown to effectively kill a variety of cancers through inhibition of tubulin polymerization...

BACKGROUND: Mouse double minute 2 (MDM2) and vascular endothelial growth factor (VEGF) are important molecules involved in tumor progression. We researched potential inhibitors that simultaneously target MDM2 and VEGF. In our recent study involving the performance of high-throughput screening with a fluorescence polarization assay, gossypol was identified as one of the top hits that inhibit protein-RNA binding activity. Because MDM2 is an RNA-binding protein and its targets include VEGF mRNA, we investigated whether gossypol has an inhibitory effect on MDM2-VEGF...

The synergistic combination of two or more chemotherapeutics frequently requires packaging in single delivery vehicles for the sequential release of each substance in a predictable manner. Here, we demonstrate for the first time that the rational engineering of a prodrug cocktail into single polymeric nanoparticles (NPs) can enable the sequential release of chemotherapeutics in a controllable manner. Exploiting combretastatin-A4 (CA4, 1) as a model antiangiogenesis agent, two ester derivatives, 2 and 3, tethered with saturated fatty acids (butanoic and heptanoic acid for 2 and 3, respectively) were synthesized...

Nitric oxide (NO) plays a critical role in endothelial functions such as cellular migration, vascular permeability and angiogenesis. Angiogenesis, the formation of new blood vessels from "pre-existing" ones is a carefully regulated process and essential during reproduction, development and wound healing. Previously our lab group reported that Secreted Frizzled-Related Protein 4 (sFRP4) could inhibit angiogenesis in both in vitro and in vivo conditions. sFRP4 belongs to a family of secreted glycoproteins that function as antagonists of the canonical Wnt signalling pathway...

Renal medullary carcinoma (RMC) is a rare but highly aggressive neoplasm that primarily affects young African Americans with sickle cell trait. Most patients present with macroscopic hematuria and have metastases at diagnosis. Chemotherapy, biologics directed against the more common renal cell carcinomas and radiation have all shown limited efficacy in treating patients with advanced RMC. We report two patients with RMC. Both had Stage IV disease. One underwent radical nephrectomy followed by radiation and biologic drug therapy but died five months later; the other underwent multiple cycles of chemotherapy plus anti-angiogenesis treatment but died 15 months after diagnosis...

BACKGROUND: Prognosis of advanced pancreatic cancer is dismal and the novel targeted therapies, albeit successfully used to treat many advanced tumors, have shown modest results. We performed a meta-analysis in order to quantify the effect size on survival of adding targeted therapy to single agent gemcitabine. METHODS: Randomized phase III trials comparing gemcitabine mono-therapy versus gemcitabine plus a targeted agent in first-line treatment of advanced pancreatic cancer designed on survival as primary outcome were selected...

VEGF and VEGFR antibodies have been used as a therapeutic strategy to inhibit angiogenesis in many diseases; however, frequent and repeated administration of these antibodies to patients induces immunogenicity. In previous studies, we demonstrated that aggretin, a heterodimeric snake venom C-type lectin, exhibits pro-angiogenic activities via integrin α2β1 ligation. We hypothesised that small-mass aggretin fragments may bind integrin α2β1 and act as antagonists of angiogenesis. In this study, the anti-angiogenic efficacy of a synthesised aggretin α-chain C-terminus (AACT, residue 106-136) was evaluated in both in vitro and in vivo angiogenesis models...

Gambogic acid (GA) is a potential anti-cancer agent with poor water-solubility, whereas heparin has anti-angiogenesis effects with good hydrophilicity. In this study, GA grafted low molecular weight heparin (GA-LMWH) was prepared and self-assembled into micelles in aqueous solution to improve the solubility and antitumor effects against hepatocellular carcinoma. The substitution of GA-LMWH is 27.5±0.2%. The micelles had a mean size of 190.4±10.8nm, a low critical micelle concentration of 2.4±0.2μgmL(-1), and the highest area under the concentration-time curve and mean retention time in the liver compared to the heart, spleen, lung and kidney (p<0...

3-Bromopyruvate (3BP) is a promising effective anticancer drug against many different tumors in children and adults. 3BP exhibited strong anticancer effects in both preclinical and human studies e.g. energy depletion, oxidative stress, anti-angiogenesis, anti-metastatic effects, targeting cancer stem cells and antagonizing the Warburg effect. There is no report about 3BP metabolism to guide researchers and oncologists to improve clinical practice and prevent drug resistance. In this article, we provide evidences that 3BP is metabolized through glutathione (GSH) conjugation as a novel report where 3BP was confirmed to be attached to GSH followed by permanent loss of pharmacological effects in a picture similar to cisplatin...

Hypoxia-inducible factor-1 (HIF-1) as a key mediator in tumor metastasis, angiogenesis, and poor patient prognosis has been recognized as an important cancer drug target. A novel series of N-(benzofuran-5-yl)aromaticsulfonamide derivatives were synthesized and evaluated as HIF-1 inhibitor. Among these compounds, 7q exhibited specific inhibitory effects on HIF-1 by downregulating the expression of HIF-1α under hypoxic conditions. It inhibited the HIF-1 transcriptional activity (IC50=12.5±0.7μM) and secretion of VEGF (IC50=18...

Burkholderia pseudomallei is a serum-resistant Gram-negative bacterium capable of causing disseminated infections with metastatic complications. However, their interaction with non-phagocytic cells is poorly understood. We observed that exposure of B. pseudomallei and the closely related yet avirulent B. thailandensis to human plasma increased epithelial cell invasion by >20 fold. Enhanced invasion was primarily driven by a plasma factor which required a functional complement cascade, but surprisingly, was downstream of C3 mediated opsonisation...

Long non-coding RNAs (lncRNAs) are involved in many biological processes, such as angiogenesis, invasion, cell proliferation, and apoptosis. They have emerged as key players in the pathology of several tumors, including hepatoblastoma. In this study, we elucidate the biological and clinical significance of CRNDE up-regulation in hepatoblastoma. CRNDE is significantly up-regulated in human hepatoblastoma specimens and metastatic hepatoblastoma cell lines. CRNDE knockdown reduces tumor growth and tumor angiogenesis in vivo, and decreases hepatoblastoma cell viability, proliferation, and angiogenic effect in vitro...
