BAL-1516
BAL-1516 is an orally active NLRP3 inhibitor with human NLRP3 Kd of 14.2 nM, mouse NLRP3 Kd of 200 nM, and blood-brain barrier penetration.BAL-1516 binds to a surface groove of the NLRP3 nucleotide-binding domain, contacts FISNA and WHD subdomains, forms three hydrogen bonds to the peripheral β-strand of the triple-ATPase, and does not alter NLRP3 ATP-hydrolysis activity.BAL-1516 shows specificity for NLRP3 over other NOD-like receptors, directly binds mouse NLRP3, and inhibits inflammasome formation in monocytes and microglia.

NLRP3 14.2 nM (IC50) |
BAL-1516 potently binds to the NACHT domain of human NLRP3 with a KD of 14.2 nM, and its binding site differs from that of MCC950 (HY-12815)[1].
BAL-1516 (10 μM; pre-incubated on ice for 30 min, then incubated with ATP at 25 °C for 68 min) does not inhibit the ATP hydrolysis activity of full-length human NLRP3 protein[1].
BAL-1516 binds to the wild-type mouse NLRP3NACHT domain with a Kd of 200 nM, exhibiting higher affinity than the lead compound BAL-0028 (HY-162333)[1].
BAL-1516 (incubated with Doxycycline (HY-N0565) for 4 h, followed by stimulation with Nigericin (HY-127019) for 1 h) potently inhibits Nigericin-induced NLRP3 inflammasome ASC speck formation in HEK293T cells expressing human NLRP3, with an IC50 of 14.5 nM[1].
BAL-1516 (0.256-4 μM; pre-incubated on ice for 30 min, followed by Nigericin stimulation for 30 min) potently inhibits the release of IL-1β and IL-18 from human induced pluripotent stem cell-derived microglia induced by LPS and Nigericin, with IC50 values of 11 nM and 9.0 nM, respectively[1].
