QX-31
QX-31 is an orally active selective NLRP3 inhibitor with a Kd value of 2.8 μM for hNLRP3. QX-31 inhibits PI3K/AKT and HIF-1α signaling. QX-31 shows anti-fibrotic effects in mouse models of unilateral ureteral obstruction and ischemia-reperfusion injury. QX-31 can be used for research on renal fibrosis.

In Vitro
QX-31 selectively binds the NLRP3 LRR domain with a KD of 1.25 μM by ITC[1].
QX-31 (1-10 μM) disrupts NEK7 recruitment and ASC oligomerization in THP-M cells[1].
QX-31 (1-10 μM) inhibits COL-I expression in kidney organoids[1].

In Vivo
QX-31 (12.5-50 mg/kg/day; p.o. (oral gavage); daily; 28 consecutive days following the initial ischemic insult) dose-dependently attenuates renal fibrosis in the IRI mouse model, reducing tubular injury, collagen deposition, myofibroblast activation, and profibrotic/inflammatory gene expression[1].

Animal Model:C57BL/6J[1]
-
Dosage:12.5 mg/kg/day; 25 mg/kg/day; 50 mg/kg/day
-
Administration:p.o. (intragastric gavage); daily; 14 consecutive days starting day 1 postsurgery
-
Result:Dose-dependently mitigated UUO-induced tubular injury and architectural damage.
It markedly reduced interstitial fibrotic burden by H&E and Masson staining and produced dose-responsive reductions in COL-I deposition and α-SMA-positive myofibroblast activation.
Suppressed FN and vimentin protein expression and downregulated proinflammatory/profibrotic genes Il6, Il1b, Tnfa, Col1a1, Col3a1, and Acta2.
QX-31 administration significantly blunted UUO-induced activation of the PI3K/AKT/HIF-1α axis and reduced protein levels of GLS1 and LDHA.

-
Result:Dose-dependently ameliorated IRI-induced renal damage and structural distortion, with reduced tubular injury scores and diminished interstitial collagen deposition.
It produced dose-responsive reductions in COL-I accumulation and α-SMA myofibroblast activation.
Downregulated FN, vimentin, and α-SMA protein expression and suppressed transcription of Il6, Il1b, Tnfa, Col1a1, Col3a1, and Acta2.
In IRI kidneys, QX-31 blunted the PI3K/AKT/HIF-1α axis and reduced GLS1 and LDHA protein levels.
