Acetohexamide (Standard) is the standard substance of Acetohexamide, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Acetohexamide (Acetohexamid) is an intermediate-acting, first-generation sulfonylurea with hypoglycemic activity. It inhibits sulfonylurea receptor 1 (SUR1) linked to the inwardly rectifying potassium channel (KIR6.2) with Ki values of 22.9 and 14.2 μM in HEK293 cells transfected with the human receptor and in rat brain, respectively. Acetohexamide is metabolized in the liver to its active metabolite hydroxyhexamide.
