Description

General description

Phenamil, a derivative of amiloride is an inhibitor of sodium channels including acid sensing ion channel (ASIC) and epithelial sodium channels (ENaC).

Application

Phenamil methanesulfonate salt has been used:

• to stimulate adipocyte differentiation in 3T3 cells
• to test its effect on lateral flagella expression in Vibrio shilonii
• in nanoparticle preparation to test its effect on osteo/odontoblastic differentiation

Biochem/physiol Actions

Phenamil is an inducer of peroxisome proliferator-activated receptor γ (PPARγ) and inhibits diamine oxidase. By favoring tribbles homolog 3 (Trb3) expression, phenamil holds therapeutic potential to treat pulmonary artery hypertension (PAH) and idiopathic PAH. It is also a bone morphogenetic protein (BMP) activator, which favors osteogenesis and odontogenesis of stem cells.
