| 生物活性 | Compound 3i (666-15)是一种有效的、选择性地抑制CREB介导的基因转录的抑制剂，IC50为81 nM。它还能抑制癌细胞的生长，而不影响正常细胞。[1] |
| IC50 | CREB: 81 nM [1] |
| In Vitro | 化合物3i(666-15)是creb介导的基因转录的有效选择性抑制剂(IC50 = 0.081±0.04 μM)。666-15还能在不伤害正常细胞的情况下有效抑制癌细胞的生长。在MDA-MB-231和MDA-MB-468细胞中，666-15的GI50值分别为73 nM和46 nM。在A549和MCF-7细胞中，666-15同样也具有较强的活性，GI50分别为0.47 μM和0.31 μM。在不依赖于直接的CREB或CBP结合反应的活细胞中，666-15可抑制CREB的转录活性[1]。 |
| In Vivo | 在体内MDA-MB-468异种移植瘤模型中，666-15可完全地抑制肿瘤生长，而没有明显毒性。对小鼠腹腔注射10 mg/kg的666-15，耐受性良好[1]。 |

| 动物实验 | HEK 293T cells in a 10 cm plate were transfected with pCRE-RLuc (6 μg) with Lipofectamine2000 following the manufacturer’s instructions. Three hours after transfection, the cells were collected and replated into 96-well plates at ?10?000 cells/well. The cells were allowed to attach to the bottom of the plates overnight. The cells were then treated with different concentrations of different compounds for 30 min when forskolin (10 μM) was added to each well. The cells were incubated for further 5 h before cell lysis using 1× 30 μL Renilla luciferase lysis buffer. An amount of 5 μL of the lysate was combined with 30 μL of benzyl-coelenterazine solution in PBS (pH 7.4, 10 μg/mL). The protein concentration in each well was determined. The Renilla luciferase activity was normalized to protein content in each well and expressed as relative luciferase unit/μg protein (RLU/μg protein). The IC50 was derived from nonlinear regression analysis of the RLU/μg protein–concentration curve [1]. |
| 细胞实验 | Each 6- to 8-week old BALB/c nude mouse was inoculated subcutaneously at the right flank with MDA-MB-468 cells (5 × 10^6) in 0.1 mL of HBSS with Matrigel (1:1) for tumor development. When the tumor volume reached approximately 100 mm3, the mice were randomized to be treated with either vehicle or 666-15 at 10 mg/kg. 3i was dissolved in 1% N-methylpyrrolidone (NMP), 5% Tween-80 in H2O. The dosing solution was prepared weekly. The mice were treated once a day for 5 consecutive days a week, and the treatment lasted for 5 weeks. During the treatment, the tumor size and body weight were measured 2–3 times a week. The tumors were measured in two dimensions using a digital caliper, and the volume was expressed in mm3 using the formula V = 0.5ab2, where a and b represent the long and short diameters of the tumor, respectively. The tumor volume was normalized to the initial tumor volume at the time of the first treatment [1]. |
