    • The anti-angiogenic functions of a polysulfated, cyclic compound, ST104P, were investigated. ST104P exhibited excellent water solubility and low cytotoxicity to endothelial cells. ST104P potently inhibited the secretion of matrix metalloproteinase (MMPs) by endothelial cells. Moreover, ST104 also perturbed the migration and tube formation of endothelial cells. Application of ST104P abolished the neovascularization in chicken choroiallantoic membrane (CAM) in a dose-dependent manner. Besides, repeated administration of ST104P into Lewis lung carcinoma resulted in delayed tumor growth and prolonged the life span of tumor-bearing mice. These results indicated that ST104P inhibited angiogenesis and may hold promises for treatment of cancer and diseases or conditions caused by excessive angiogenesis.
    • 研究了多硫酸化环状化合物ST104P的抗血管生成功能。 ST104P显示出优异的水溶性和对内皮细胞的低细胞毒性。 ST104P能有效地抑制内皮细胞分泌基质金属蛋白酶(MMPs)。 此外,ST104还扰乱了内皮细胞的迁移和管形成。 ST104P的应用以剂量依赖的方式消除了鸡绒毛膜膜(CAM)中的新生血管形成。 此外,将ST104P重复给予Lewis肺癌导致肿瘤生长延迟,延长荷瘤小鼠的寿命。 这些结果表明,ST104P抑制血管生成,可能有助于治疗癌症和由过度血管发生引起的疾病或病症。
