CCG-203971
生物活性
CCG-203971 is an inhibitor of the Rho/MKL1/SRF transcriptional pathway, which has been shown to play a role in metastasis of melanoma and breast cancer and clinically associated with castration-resistant prostate cancer. CCG-203971 is a second-generation analog of CCG-1423 (SML0987) with an IC50 of 4.2 μM vs 1 μM for CCG-1423, but less cytotoxicity. In mouse studies, CCG-203971 inhibited invasion of PC-3 prostate cancer cells and was well tolerated up to doses of 100 mg/kg IP over 5 days.
The Rho/MRTF/SRF pathway has also been shown to be involved in multiple types of solid organ fibrosis. CCG-203971 repressed both matrix-stiffness and TGF-β-mediated fibrogenesis in human colonic myofibroblasts and showed antifibrotic activity in a murine model of skin injury and in pulmonary fibrosis lung fibroblasts.
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。
