XAN35021, also known as ROMKinhibitor 25, or ROMK-IN-25, is a potent and selective ROMKinhibitor with improved pharmacokinetic properties. This product has no formal name at the moment. For the convenience of communication, a temporary code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).
PF-06807656 is insensitive to the introduction of the N171D mutation in the ROMK conduction pore that greatly diminishes the activity of other small-molecule inhibitors. PF-06807656 is an effective ROMKinhibitor (Tl+ flux IC50 = 160 nM).
