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.

P Barbry et al.
Biochemistry, 28(9), 3744-3749 (1989-05-02)
The existence of distinct forms of the epithelium Na+ channel that differ in their sensitivity to amiloride has been repeatedly suggested by physiological data. The biochemical basis for these differences was analyzed by using phenamil, the most potent inhibitor known

Several new amiloride analogues and two reported photoaffinity analogues were tested for irreversible inhibition of short-circuit current, Isc, in toad bladder. Bromoamiloride, a photoaffinity analogue, induced 40% irreversible inhibition at 500 microM after irradiation with ultraviolet light greater than or

In this study, we show the induction of lateral flagella by the action of the sodium channel blocker phenamil, in the marine bacterium Vibrio shilonii, a coral pathogen that causes bleaching. We analyzed the growth and morphology of cells treated

Pulmonary artery hypertension (PAH) is characterized by elevated pulmonary artery resistance and increased medial thickness due to deregulation of vascular remodeling. Inactivating mutations of the BMPRII gene, which encodes a receptor for bone morphogenetic proteins (BMPs), are identified in ∼60%

Water balance in the lung is controlled via active Na+ and Cl- transport. Electrophysiological measurements on lung epithelial cells demonstrated the presence of a Na+ channel that is inhibited by amiloride (K0.5 = 90 nM) and some of its derivatives
