产品描述 | Curcumin (Natural Yellow 3) is a phenolic natural product, an inhibitor of histone acetyltransferase p300/CREB (IC50=25 μM) with specificity. Curcumin has a wide range of pharmacological activities such as antitumor, anti-inflammatory and antioxidant. |
靶点活性 | p300 HAT:25 μM |
体外活性 | 方法:视网膜母细胞瘤细胞 SO-Rb50 和 Y79 用 Curcumin (10-50 μM) 处理 24 h,使用 CCK-8 方法检测细胞活力。 结果:Curcumin 剂量依赖显著降低了 SO-Rb50 和 Y79 细胞的活力,IC50 分别为 38.4 μM 和 34.8 μM。[1] 方法:小鼠结肠癌细胞 MC38 用 Curcumin (5-50 μM) 处理 48 h,使用 Flow Cytometry 方法检测细胞凋亡情况。 结果:Curcumin 剂量依赖性诱导 MC38 细胞凋亡。[2] 方法:人胰腺癌细胞 PANC1 用 Curcumin (10-80 μg/mL) 处理 24 h,使用 Immunofluorescence 方法检测自噬标志物 LC3。 结果:点状自噬体在40 μg/mL Curcumin 处理组细胞中的表达水平最高。[3] |
体内活性 | 方法:为检测体内抗肿瘤活性,将 Curcumin (100-200 mg/kg) 灌胃给药给携带小鼠结肠癌肿瘤 MC38 的 C57BL/6J 小鼠,每三天一次,持续三周。 结果:Curcumin 治疗组小鼠的平均肿瘤体积和肿瘤重量显著降低,200 mg/kg 治疗组的肿瘤体积和瘤重也显著低于 100 mg/kg 治疗组。[2] 方法:为检测体内抗肿瘤活性,将 Curcumin (25-50 mg/kg) 腹腔注射给携带艾氏腹水瘤 EAT 的 BALB/c 小鼠,每天一次,持续十天。 结果:Curcumin 50 mg/kg 组周围组织内 EAT 细胞数量明显少于肿瘤对照组。[4] |
细胞实验 | 1×104 B16-R cells are cultivated as monolayer culture for 12 hr. They were then incubated in 200 μL of RPMI, 10% FBS containing curcumin at final concentrations from 1–100 μM in 96-multiwell plates for 24-48 hr. After these incubations, cells are washed twice in PBS and 500 μl of fresh culture medium containing MTT (0.3 mg/mL) are added for colorimetric assay. (Only for Reference) |
