生物活性
CCG-222740 is a selective, orally active Rho/myocardin-related transcription factor (MRTF) pathway inhibitor. CCG-222740 is also a potent inhibitor of alpha-smooth muscle actin protein expression. CCG-222740 markedly decreased SRF reporter gene activity and showed a greater inhibitory effect on MRTF/SRF target genes than the previously described MRTF-A inhibitor CCG-203971. CCG-222740 increases the protein levels of p27 and decreased cyclin D1. CCG-222740 treatment decreased cell viability of CAFs, with an IC50 of~10 μM.
In vivo, CCG-222740 (100 mg/kg; oral gavage for 7 days) significantly reduces α-SMA levels in the pancreas of caerulein-stimulated KC mice.

| 细胞系 | Cancer associated fibroblasts (CAFs) |
| 方法 | Murine cancer associated fibroblasts (CAFs) are cultured in DMEM supplemented with 10% fetal bovine serum(FBS). CAFs are treated with several concentrations of CCG-222740 (740) for 72 hours, and levels of Cyclin D1 and p27 are evaluated by western blot. |

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。
