产品详情
生物活性:
Procyanidin C1 (PCC1), a natural polyphenol with oral activity, causes DNA damage, cell cycle arrest and induces apoptosis. Procyanidin C1 decreases the level of Bcl-2, but enhances BAX, caspase 3 and 9 expression in cancer cells. Procyanidin C1 shows senotherapeutic activity and increases lifespan in mice.

体内研究:
原花青素 C1 (20 mg/kg;腹腔注射;第一次 MIT 给药后 2 周,然后每两周给药一次) 促进肿瘤消退。原花青素 C1 (20 mg/kg;腹腔注射;持续 7 d) 在注射衰老小鼠胚胎成纤维细胞的小鼠中显示出抗衰老功效。原花青素 C1 (20 mg/kg;口服;持续 3 d) 可延长老年小鼠的寿命。Animal Model:Non-obese diabetes and severe combined immunodficiency mice with PSC27 and PC3 cancer cells injection, and pre-treated with mitoxantrone (MIT)
Dosage:20 mg/kg
Administration:Intraperitoneal injection; 20 mg/kg; 2 weeks after the first MIT dose and then delivered biweekly
Result:Remarkably enhanced tumour regression (55.2% reduction in tumour size compared with MIT alone; 74.9% reduction in tumour volume compared with the placebo treatment) and depleted the majority of senescent cells in chemotherapy treated animals.
Animal Model:24-27 months of age mice (both sexes)
Dosage:20 mg/kg
Administration:Oral gavage; 20 mg/kg; for three consecutive days
Result:Enhanced the median post-treatment lifespan with 64.2% and decreased the mortality hazard than the vehicle-treated group.

体外研究:
Procyanidin C1 (6.25-100 μg/mL;48 h) 对 MCF-7 和 MDA-MB-231 细胞具有细胞毒活性。 Procyanidin C1 (35 μg/mL;48 h) 影响 MCF-7 和 MDA-MB-231 癌细胞的细胞周期。 Procyanidin C1 显著上调 MCF-7 和 MDA中 的 Chk 1和 Chk 2-MB-231 癌细胞。Procyanidin C1 (27.85 和 66.41 μL) 在 MCF-7 和 MDA-MB-231 癌细胞中诱导显著的 DNA 损伤。 Procyanidin C1 (45 μg/mL;72 h) 降低 Bcl-2 的表达水平,增加 BAX 的表达水平,增加 caspase 3 和 9 的活性,诱导细胞凋亡 MCF-7 和 MDA-MB-231 癌细胞。
