1 Consistent with these findings, reconstituted SUR2A/KIR6.2 and SUR2B/KIR6.2 channels revealed similar sensitivities for glibenclamide and tolbutamide. Glyburide potassium inwardly-rectifying channel, subfamily J, member 11 Rattus norvegicus
2 Consistent with these findings, reconstituted SUR2A/KIR6.2 and SUR2B/KIR6.2 channels revealed similar sensitivities for glibenclamide and tolbutamide. Glyburide potassium inwardly-rectifying channel, subfamily J, member 11 Rattus norvegicus
3 Potencies of glibenclamide, glipizide, tolbutamide, and meglitinide to inhibit activity of SUR1/KIR6.2 and SUR2B/KIR6.2 channels were 3- to 6-fold higher than binding affinities of these drugs with concentration-inhibition relations being significantly steeper (Hill coefficients 1.23-1.32) than binding curves (Hill coefficients 0.93-1.06). Glyburide potassium inwardly-rectifying channel, subfamily J, member 11 Rattus norvegicus
