Selective inhibitors

repaglinide pIC₅₀ 7.0 [12]

Comment

The sulfonyurea drugs (acetohexamide, tolbutamide and glibenclamide) appear to bind sulfonylurea receptors and it has been shown experimentally that tritiated glibenclamide can be used to pull out a 140 kDa protein identified as SUR1 (now known as ABCC8) [8]. SUR2 (ABCC9) has also been identified [4]. However, this is not the full mechanism of action and the functional channel has been characterised as a hetero-octamer formed by four SUR and four K_ir6.2 subunits, with the K_ir6.2 subunits forming the core ion pore and the SUR subunits providing the regulatory properties [6]. Co-expression of K_ir6.2 with SUR1, reconstitutes the ATP-dependent K⁺ conductivity inhibited by the sulfonyureas [4].
