产品活性:Capsaicin ((E)-Capsaicin) 是辣椒中的活性成分,是一种 TRPV1 激动剂。Capsaicin 具有减轻疼痛、抗氧化、抗炎、神经保护和抗癌作用。
体外:Capsaicin (50-300 µM;24-72 小时) 表现出剂量和时间依赖性方式细胞生长的减少。观察到的 IC50 值约为 150 µM[2]。 Capsaicin (50-300 µM; 24-72 小时) 显示细胞质细胞色素 c 增加、胱天蛋白酶 3 和 PARP (p85) 水平激活,并降低抗凋亡 Bcl-2 蛋白,增加促凋亡 Bad/Bax 表达[2]。 Capsaicin 增加核凝聚、核 DNA 碎片和亚 G1 DNA 含量[2]。 Capsaicin 通过降低细胞周期蛋白 B1 和 D1 调节剂以及细胞周期蛋白依赖性蛋白激酶 cdk-1、cdk-2 和 cdk-4 的表达来抑制 FaDu 细胞在 G1/S 期的细胞周期进程[2]。 MCE尚未独立证实这些方法的准确性。仅供参考。
体内:Capsaicin 通过改变凋亡调节因子 p53、Bcl-2、Bax 和 caspase-3 的蛋白表达来抑制肺癌的发展[2]。 Capsaicin (每只小鼠 2 µg,40 µL,注入左后爪足底表面) 可诱导小鼠出现疼痛相关行为[4]。 Capsaicin (每只大鼠 10 µL 中 3-30 µg,足底注射) 可诱导大鼠继发性机械超敏反应 (SMH) (临床上用作潜在预测神经性疼痛的模型)[5]。 Capsaicin (每只大鼠 25 μL 中 0-500 μg,皮下注射到右侧触须垫中心) 会引起大鼠口面部区域疼痛[6]。 大剂量时,辣椒素可能需要在麻醉状态下给药[7][8]。 Capsaicin 比 Dihydrocapsaicin (HY-N0361) 更刺激[9]。 Note: 辣味呛人,请注意。Capsaicin ((E)-Capsaicin) 在不同情况下的半致死剂量 (LD50): Animal Backgroud Route LD50 References Rat adult ip 10 mg/kg [10] female; 51-54 g ip 10.40-13.20 mg/kg [11] female; 141 g ip 9.50 mg/kg [11] male po 161.2 mg/kg [12] female po 148.1 mg/kg [12] Mice male; 25-35 g iv 0.56 mg/kg [11] male po 118.8 mg/kg [12] male ip 7.56 mg/kg [10] female po 97.4 mg/kg [12] female; 30 g ip 6.50 mg/kg [11] ip 7.65 mg/kg [11] im 7.80 mg/kg [11] sc 9.00 mg/kg [11] po 60-75 mg/kg [11] po 190 mg/kg [11] pr >218 mg/kg [11] dermal >512 mg/kg [11] intratracheal 1.60 mg/kg [11] Hamster male; 65 g ip >120 mg/kg [11] Guinea Pig male; 405 g ip >1.10 mg/kg [11] Rabbit adult; 503 g ip >50 mg/kg [11] MCE尚未独立证实这些方法的准确性。仅供参考。
