NLRP3 Inflammasome Inhibitor - Proton pump inhibitor

Glybenclamide, also known as glyburide, is an ATP-sensitive potassium channel inhibitor.

It blocks the maturation of caspase-1 and pro-IL-1β by inhibiting the K+ efflux [1].

Glybenclamide has been shown to potently block the activation of the NRLP3 inflammasome induced by PAMPs, DAMPs and crystalline substances [2, 3].

Research suggests that this inhibitor works downstream of the P2X7 receptor but upstream of NRLP3 [2].
