Product Introduction
Bioactivity
| 名称 | Catechin |
| 描述 | Catechin (Cianidanol) is a natural phenol, an antioxidant that inhibits cyclooxygenase-1 (COX-1) (IC50=1.4 μM). Catechin has a wide range of biological activities such as antitumor, antioxidant and antibacterial. |
| 细胞实验 | LB02 cells were resuspended in RPMI 10% FBS in a concentration of 5x105 cells/mL. The cultures were performed in 96-well round-bottomed microtitre plates in presence of different concentrations of catechin or rutin (10, 50, 100 or 200 μg/mL). After 48 h at 37 ºC in a humidified atmosphere with 5% CO2 in the air, cultures were pulsed with 1 μCi of 3H-thymidine/well and maintained for an additional 18 h period prior to a semiautomatic method harvest.

| 体外活性 | 方法:六株人白血病细胞系用 Catechin 处理 24 h,使用 MTT assay 检测细胞活力。 结果:Catechin 对 APL 细胞系 (NB4-R1、NB4-R2 和 NB4) (IC50<200 µM)、Kasumi-1 细胞 和 K562 细胞具有显著的生长抑制作用。U937 细胞对儿茶素的敏感性相对较低,IC50 高于 200 µM。[1] 方法:成纤维细胞用 Catechin (10 µM) 处理 30 min,然后用 H2O2 (0.1mM) 进行氧化应激诱导 24 h,使用 TUNEL 染色检测细胞凋亡。 结果:Catechin 处理的成纤维细胞 TUNEL 染色阳性细胞的百分比显著降低。[2] |
| 体内活性 | 方法:为检测体内抗肿瘤活性,将 Catechin (1-4 mg/mouse) 灌胃给药给 1,2-DMH 诱导大肠癌的 Kunming 小鼠,每周五次,持续 23 周。 结果:Catechin 茶对 1,2-DMH 诱导大肠癌具有预防作用。免疫组织化学研究表明,Catechin 能提高组织中超氧化物歧化酶 (SOD) 的活性。[3] |
