生物活性
产品描述 |
一种从红曲霉发酵米(红霉米)提取物中分离出来的橙色的氮杂酮类色素。 |
|
靶点/IC50 |
Apoptosis |
|
体外研究 |
Rubropunctatin (1.5-30μM; 24h) shows selective tumoricidal effect on the human gastric carcinoma BGC-823 cells and no significant toxicity toward normal epithelial cell GES-1.Rubropunctatin (5-30μM; 6-24h) induces apoptosis in a dose- and time-dependent manner in BGC-823 cells.Rubropunctatin (0.75-8.0µg/ml) exhibits DDPH radical scavenging activity,inhibition of super oxide radical generation and ferric reducing activity.

体内研究 |
Rubropunctatin (8-32mg/kg; i.v. for 5 times) has anti-tumor effect mice.Rubropunctamine inhibits 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in mice, with an ID50 of 0.11mg/ear. |
|
Animal Model: |
Male nude mice (5 weeks) are inoculated with BGC-823 cells |
|
Dosage: |
8, 32mg/kg |
|
Administration: |
I.v. five times (day 1st,4th,7th,10th,and 13th) |
|
Result: |
Diminished the tumor volume by 11.1% (8mg/kg) and 24.2% (32mg/kg). Reduced the tumor weight by 23.5% (8mg/kg) and 37.7% (32mg/kg). No significant difference was observed on the body weight. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液,使用的计算公式为:
开始浓度 x 开始体积 = 最终浓度 x 最终体积
稀释公式
稀释公式一般简略地表示为:C1V1 = C2V2 ( 输入 输出 )
