ML345
Based on 1 publication(s) in Google Scholar
ML345 is a potent and selective inhibitor of insulin-degrading enzyme (IDE) and NLRP3, with an IC50 of 188 nM against IDE. ML345 targets the Cys819 residue of IDE to inhibit IDE. ML345 selectively binds to NLRP3 in a non-covalent manner. ML345 inhibits inflammatory cytokines (IL-1β, IL-6) and exhibits potent anti-inflammatory activity. ML345 exerts a protective effect against miscarriage.

ML345 (0.25-1 μM; 30 min pre-incubation, 30 min nigericin stimulation) potently blocks nigericin-induced NLRP3 inflammasome activation in primary murine BMDMs with an IC50 of 197.7 nM, reducing inflammatory cytokine maturation, caspase-1 cleavage, and pyroptosis without altering IL-6 or TNF secretion[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
ML345 (10 mg/kg; i.p.; administered three times during pregnancy) effectively ameliorates LPS-induced abortion, reduces the levels of inflammatory cytokines in maternal tissues, and inhibits the activation of NLRP3[1].
