Phenamil methanesulfonate is a potent analog of Amiloride that functions as a strong and less reversible epithelial sodium channel (ENaC) blocker with an IC50 of 400 nM, Phenamil methanesulfonate also acts as a competitive inhibitor of TRPP3 and suppressing TRPP3-mediated calcium transport with an IC50 of 140 nM in Ca2+ uptake assays. Phenamil methanesulfonate robustly activates BMP signaling to promote bone repair, supporting its use in cystic fibrosis lung disease, ion channel biology, and regenerative medicine research.

Phenamil is an inhibitor of epithelial sodium channels, which activates the osteomorphin protein signalling pathway to promote bone repair and induces significant fat formation.
