生物活性

Beta-Sitosterol (purity>75%) is a phytosterol with oral activity. Beta-Sitosterol (purity>75%) interferes with a variety of cell signaling pathways, including the cell cycle, apoptosis and cell proliferation. Beta-Sitosterol (purity>75%) has anti-inflammatory, antioxidant, and antitumor activities[1][2][3].

体外研究
(In Vitro)

Beta-Sitosterol purity>75% (16 μM, 1, 3, 5 天) 可抑制 MDA-MB-231 人乳腺癌细胞生长和诱导细胞凋亡[1]。
Beta-Sitosterol purity>75% (120, 240 μM, 24 h) 对 COLO 320 DM 细胞有明显的剂量依赖性生长抑制作用 (IC50 为 266.2 μM)。通过清除活性氧诱导细胞凋亡，抑制人结肠癌细胞中 β-catenin 和 PCNA 抗原的表达[2]。
