CCG-203971 is a small-molecule inhibitor of the Rho/MRTF/SRF pathway with the IC50 value of 0.64 μM for SRE.L. It inhibits Rho-mediated gene transcription.

CCG-1423 inhibits RhoA/C-mediated gene transcription and the invasion of rho-overexpressing cell lines.

Zoledronic acid, a potent osteoclast inhibitor, induces apoptosis in osteoclasts by inhibiting enzymes of the mevalonate pathway and preventing the isoprenylation of small GTP-binding proteins such as Ras and Rho.
