Abstract:
:Angiogenesis is a process through which new capillaries are formed from pre-existing ones, which contributes significantly to the pathogenesis of numerous diseases, such as cancer and chronic inflammatory disorders. The β-D-mannuronic acid (M2000) is a novel non-steroidal anti-inflammatory drug (NSAID) with immunosuppressive effects and is a matrix metalloproteinase (MMP) inhibitor. This research aimed to study the anti-angiogenesis effects of M2000 under in vitro and in vivo models. The cytotoxic and anti-proliferative effects of M2000 were examined using the trypan blue method and the MTT assay, respectively. The 3D collagen-cytodex model and the chick chorioallantoic membrane (CAM) assay were then used to evaluate the anti-angiogenesis property of M2000. Cytotoxicity assay revealed that M2000 (at concentrations of less than 100 μg/mL) had no cytotoxic effect on human umbilical vein endothelial cells (HUVECs). It was also illustrated that M2000 had little or no anti-proliferative effect on HUVECs. In addition, the anti-angiogenesis effects of M2000 were shown to be marginal in the in vitro model and both significant and dose-dependent in the in vivo status. This study showed that M2000 could be considered as an anti-angiogenic molecule which more likely exerts its activity mainly via indirect effects on endothelial cells and its anti-inflammatory effects may partly be attributable to its anti-angiogenic activity. Therefore, it could be recommended as a candidate for prevention and treatment of cancer, chronic inflammatory diseases, and other angiogenesis-related disorders.
