MJ33
MJ-33 is a competitive phospholipase A₂ (PLA₂) inhibitor with an IC50 of 0.3 μM. MJ-33 inhibits the activation of NOX2 by blocking the PLA₂ activity of Prdx6, thereby reducing the production of ROS. MJ-33 effectively inhibits the activity of acidic PLA₂ (pH 4.0), reduces the degradation of pulmonary surfactant phosphatidylcholine (PC), but has no effect on alkaline PLA₂ (pH 8.5). MJ-33 significantly alleviates lung oxidative damage induced by ischemia-reperfusion (I/R). MJ-33 significantly inhibits the invasive, migratory and adhesive abilities of prostate cancer cells by suppressing the MAPK, AKT, NF-κB and AP-1 signaling pathways. MJ-33 can be used to study ROS-related diseases and prostate cancer.

MJ33 (50-1000 nM; 24-48 h) reduces the viability of DU145, LNCaP and PC-3 human prostate cancer cells in a concentration-dependent manner, with DU145 cells showing the highest sensitivity and an EC50 of 458.32 nM after 24 h of incubation[1].
MJ33 (50-200 nM; 24 h) inhibits the invasion of human prostate cancer cell line DU145 in a concentration-dependent manner, with an inhibition rate of 15%-70% observed after treatment at 50-200 nM for 24 h, and this effect is independent of cytotoxicity[1].
MJ33 (50-200 nM; 24 h) inhibits the migration of human prostate cancer cell line DU145 in a concentration-dependent manner, with an inhibition rate of 30%-75% observed after treatment at 50-200 nM for 24 h, and this effect is independent of cytotoxicity[1].
MJ33 (50-200 nM; 24 h) inhibits the adhesion of DU145 human prostate cancer cells in a concentration-dependent manner, with an inhibition rate of 10%-45% observed after treatment at 50-200 nM for 24 h, and this effect is independent of cytotoxicity[1].
MJ33 (50-200 nM; 24 h) reduces the enzymatic activities of MMP-2, MMP-9 and u-PA in DU145 human prostate cancer cells in a concentration-dependent manner[1].
MJ33 (50-200 nM; 6-24 h) reduces the protein levels of MMP-2, MMP-9 and u-PA in a concentration-dependent manner in DU145 human prostate cancer cells after 24 h of incubation, and decreases the levels of phosphorylated JNK, ERK, p38, AKT as well as nuclear NF-κB p65, c-fos and c-Jun after 6 h of incubation[1].
MJ33 (100-200 nM; 6 h) inhibits the DNA-binding activities of NF-κB and AP-1 in DU145 human prostate cancer cells in a concentration-dependent manner[1].
MJ33 (20 μM; 24 h) restores the GSH/ROS balance in cultured C57BL/6J primary hippocampal neurons with AAV-mediated D2HGDH knockdown, without affecting cell viability[2].
MJ33 completely inhibits NOX2-dependent ROS production in wild-type mPMVEC stimulated by AngII[3].
MJ33 (4 μM; 15 min) reduces concanavalin A (Con A)-stimulated NOX2-dependent O2•− production by 79% in bone marrow neutrophils (PMNs) from wild-type mice[3][4].
MJ33 (5-25 μM; 2-10 day) exerts no effect on the proliferation or clonogenic survival of human lung cancer cell line A549 at concentrations up to 25 μM over an exposure period of up to 10 days[3][4].

MJ33 (0.4-10 nmol; intratracheal administration; intravenous administration; single administration) inhibits pulmonary Prdx6 PLA2 activity in mice by approximately 85%, and the activity recovers in a dose-dependent manner within 72 h; among the administration routes, intratracheal administration results in higher pulmonary uptake, while intravenous administration leads to moderate pulmonary uptake[3].
MJ33 (4 nmol; intravenous injection) reduces ROS production by 66% in a mouse model of lung ischemia/reperfusion injury, and essentially abolishes oxidative stress and increased pulmonary permeability[3].
