Candesartan N-glucuronide is a metabolite of candesartan. It is produced by human UDP-glucuronosyltransferase, which belongs to the subfamily of uridine diphosphate (UDP)-glucuronosyltransferases. Candesartan N-glucuronide inhibits angiotensin II receptor type 1 (AT1) and has minimal effects on angiotensin II receptor type 2 (AT2). Candesartan N-glucuronide binds to the AT1 receptor and blocks its activation by angiotensin II. This binding inhibits the uptake of sodium ions into cells and causes an increase in potassium ion secretion, leading to vasodilation. Candesartan N-glucuronide also induces the expression of cytochrome P450 3A5, which results in increased metabolism of drugs such as paclitaxel.

The terminal residues of oligosaccharides are transferred from the lipid carrier to L-glycero-D manno heptose, forming a stable acylated glycoside. This reaction mechanism is similar to that of polymyxin B, but with a difference in reactivity due to steric hindrance.
