Expert opinion on therapeutic patents, 23(10), 1383-1389 (2013-08-21)
Novel molecular platforms for epithelial sodium channel (ENaC) modulators are claimed in the following six patents: WO2012035158(A1); WO2009074575(A2); WO2011028740(A1); WO2009150137(A2); WO2011079087(A1); WO2008135557(A1). These ENaC inhibitors may be used in blocking transepithelial sodium and consequently water absorption across airway epithelia. This

Intestinal calcium (Ca²⁺) absorption occurs via paracellular and transcellular pathways. Although the transcellular route has been extensively studied, mechanisms mediating paracellular absorption are largely unexplored. Unlike passive diffusion, secondarily active paracellular Ca²⁺ uptake occurs against an electrochemical gradient with water

The epithelial sodium channel (ENaC) is comprised of three homologous subunits. Channels composed solely of α- and β-subunits (αβ-channels) exhibit a very high open probability (Po) and reduced sensitivity to amiloride, in contrast to channels composed of α- and γ-subunits

Lithium is the most common cause of nephrogenic diabetes insipidus (Li-NDI). Hydrochlorothiazide (HCTZ) combined with amiloride is the mainstay treatment in Li-NDI. The paradoxical antidiuretic action of HCTZ in Li-NDI is generally attributed to increased sodium and water uptake in

Na(+) reabsorption from the distal renal tubule involves electroneutral and electrogenic pathways, with the latter promoting K(+) excretion. The relative activities of these two pathways are tightly controlled, participating in the minute-to-minute regulation of systemic K(+) balance. The pathways are
