生物活性

• 描述: 褐藻糖胶是一种具有生物活性的多糖,是α-淀粉酶和α-葡萄糖苷酶的有效抑制剂。抗凝血、抗肿瘤、抗氧化和抗疲劳活性[1]。

  研究领域 >> 代谢疾病
• 体外研究: 褐藻糖胶是一种生物活性多糖,大量存在于褐藻中[1]。从结藻中提取的岩藻糖胶是一种更有效的α-葡萄糖苷酶抑制剂,其IC50范围为0.013至0.047 mg/mL,比从水泡囊藻中提取的岩藻糖胶的抑制作用(IC50=0.049 mg/mL)。从泡囊藻中提取的岩藻糖胶不抑制α-淀粉酶活性,而从结藻中提取的岩藻糖胶在5 mg/mL浓度下降低α-淀粉酶活性7-100%,具体取决于藻类收获期。结藻褐藻糖胶抑制α-淀粉酶的IC50为0.12-4.64 mg/mL[1]。岩藻糖胶是一种富含岩藻糖的硫酸多糖,通常存在于海藻的细胞壁中,但最近也从陆地来源分离出来。褐藻糖胶对与氧化应激相关的多种代谢性疾病具有诱人的治疗潜力[2]。
• 体内研究: 褐藻糖胶(单次注射25mg/kg/体)不抑制肿瘤细胞增殖,而三次注射10mg/kg/体可显著降低肿瘤生长和转移[3]。动物模型：小鼠[3]剂量：10-400mg/kg给药：腹腔注射；其次是全身照射结果：注射100mg/kg的小鼠在照射后30d的存活率最高。
