生物活性
GDC-0152是一种有效的XIAP-BIR3, ML-IAP-BIR3, cIAP1-BIR3和cIAP2-BIR3拮抗剂,Ki分别为28 nM, 14 nM, 17 nM和43 nM,对cIAP1-BIR2和cIAP2-BIR2具有低的亲和力。GDC-0152可阻断IAP蛋白和促凋亡分子参与的蛋白质-蛋白质的相互作用。GDC-0152瞬时转染HEK293T细胞,表现为扰乱XIAP结合部分处理的caspase-9并扰乱ML-IAP,CIAP1,cIAP2和Smac蛋白的结合。在黑色素瘤SK-MEL28细胞中,GDC-0152有效抑制ML-IAP和Smac蛋白的内源性结合。

方法 | Cell Viability and Caspase Activation Assays Human breast carcinoma MDA-MB-231 were obtained from ATCC. Normal human mammary epithelial cells (HMECs) were obtained from Cambrex Corp.. Cells were dissociated from tissue culture flasks by incubation with Accutase(R) (Innovative Cell Technology Inc.) for 5–10 minutes. Detached cells were washed with phosphate-buffered saline (PBS) and were resuspended in assay media (MDA-MB-231 cells: RPMI1640 supplemented with 10% fetal bovine serum [Sigma-Aldrich] and 2 mM L-glutamine [GlutaMAX-1; Gibco/Invitrogen Corp.]) or culture media (HMECs: MEBM(R) with MEGM SingleQuots(R) provided by Cambrex Corp.). Cells were placed in tissue culture-treated, white-wall (Corning, Inc.) or black-wall (PE Biosystems), clear-bottom, 96-well plates at 1 × 104 cells/well in a volume of 50 μL. The plates were incubated at 37°C and 5% CO2 overnight, the media was removed, and 1 or it's enantiomer were added in assay media. Cells cultured in white-wall, clear-bottom plates were incubated at 37°C and 5% CO2 for 3 days before cell viability was measured using the CellTiter-Glo(R) luminescent cell viability assay kit (Promega Corp.) according to the manufacturer's instructions. Cells seeded in black-wall, clear-bottom plates were incubated at 37°C and 5% CO2 for 3–24 hours before caspase-3 and -7 homogeneous activities were assessed using the Apo-ONE(R) caspase-3/7 assay kit (Promega Corp.) according to the manufacturer's instructions. |

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
动物 A的Km系数 |
例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
