| Bioactivity | GDC-2394 is an orally active and selective NLRP3 inhibitor, and also inhibits IL-1β with IC50s of 0.4 μM (human IL-1β) and 0.1 μM (mouse IL-1β). GDC-2394 inhibits NLRP3-induced caspase-1 activity without inhibiting NLRC4-dependent inflammasome activation[1][2]. | |||||||||
| Invitro | GDC-2394 (20 μM; 30 min) inhibits NLRP3-induced apoptosis associated speck-like protein containing CARD (ASC) speck formation in THP-1 cells[1].GDC-2394 (1 nM-10 μM; 7 d) inhibits human macrophage IL-1β and IL-18 production after activation of the NLRP3 inflammasome[1].GDC-2394 (0-20 μM; 30 min) inhibits NLRP3-dependent caspase-1 activation (IC50=51 nM) in THP-1 cells, also inhibits NLRP3-dependent IL-1β release (IC50=63 nM) and NLRC4-dependent IL-1β release (IC50>20 μM) in mouse bone marrow-derived macrophages (mBMDMs)[1]. | |||||||||
| In Vivo | GDC-2394 (compound 20) (1 mg/kg, 10 mg/kg; p.o.; single dose) inhibits production of IL-1β in an acute mouse peritonitis model[1].GDC-2394 (25 mg/kg; once daily for 7 d) reduces paw swelling and pain in a functional rat model of gouty arthritis[1].Preclinical PK of GDC-2394[1].Species | |||||||||
