Biological Activity

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.

Cell Experiment
Cell lines Cancer associated fibroblasts (CAFs)
Preparation method 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.
Concentrations 10 μM
Incubation time 72 h
Animal Experiment
Animal models Nine-week old KC mice
Formulation dissolved in 15% (v/v) DMSO and then added to a solution of 10% tween-20 in saline
Dosages 100 mg/kg
Administration Oral gavage; daily; for 7 days
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
