MJ-33 lithium salt is a competitive phospholipase A2 (PLA2) inhibitor with an IC50 of 0.3 μM. MJ-33 lithium salt inhibits NOX2 activation and reduces ROS production by blocking the PLA2 activity of Prdx6. MJ-33 lithium salt effectively inhibits the activity of acidic PLA2 (pH 4.0) and reduces the degradation of alveolar surfactant phosphatidylcholine (PC), but exerts no effect on alkaline PLA2 (pH 8.5). MJ-33 lithium salt significantly alleviates lung oxidative injury induced by ischemia-reperfusion (I/R). MJ-33 lithium salt significantly inhibits the invasion, migration and adhesion abilities of prostate cancer cells by suppressing the MAPK, AKT, NF-κB and AP-1 signaling pathways. MJ-33 lithium salt can be used for the research of ROS-related diseases and prostate cancer .

NPE-caged-proton is a reagent that releases protons under UV light and has the activity of activating the fusion protein GP64 under weak acidic conditions. NPE-caged-proton can promote the binding of enveloped viruses to liposome membranes with acidic phospholipids in an environment of pH 4.0 to 5.5, thereby initiating membrane fusion. The ultraviolet unblocking effect of NPE-caged-proton can lower the environmental pH, thereby triggering the process of viral membrane fusion. When studying the interaction between viruses and cell membranes, NPE-caged-proton provides a valuable tool for revealing the subtle behaviors of viruses in different chemical and biochemical environments .

M-H2S is an endoplasmic reticulum-targeted ratio-type near-infrared fluorescent probe (Ex/Em : 480 nm/560 nm) specifically designed for the detection of hydrogen sulfide (H2S) in living cells and zebrafish. M-H2S exhibits detection limit for H2S of 39.1 nM, and the fluorescence intensity ratio (F₆₅₀/F₅₆₀) within the range of 0-40 μM shows a linear relationship with the H2S concentration. M-H2S responds best under pH = 7.2 (the normal physiological pH of the endoplasmic reticulum) conditions, making it suitable for the detection of the microenvironment of the endoplasmic reticulum. M-H2S can be used to study the role of H2S in endoplasmic reticulum function, stress response, and related diseases .

Fluorescent Dye

LysoAIE2 is a Fluorescent probe for lysosomal viscosity detection and live-cell imaging. Its detection mechanism relies on the aggregation-induced emission effect: it exhibits only weak fluorescence in non-viscous media; in viscous environments, restricted intramolecular motion inhibits non-radiative energy dissipation pathways, thereby significantly enhancing fluorescence intensity. It achieves specific targeting of lysosomes through the proton acceptor property of its indole ring structure, while its hydroxyl group endows it with excellent water solubility. This probe is basically unaffected by microenvironmental polarity and pH within the range of pH 4.0 to pH 8.0, which avoids interference from these factors in viscosity measurement. LysoAIE2 has an emission wavelength of 570 nm. It can be used to monitor lysosomal viscosity changes during processes such as Dexamethasone (HY-14648)-induced lysosomal migration and starvation-induced mitophagy in live cells; at concentrations up to 40 μM, cell viability remains above 80%, demonstrating excellent biocompatibility .

Neurological Disease

Sodium bromide (NSC 77384; Sanibrom 40) is a GABA-ergic system modulator that crosses the blood-brain barrier, and it effectively reduces and blocks epileptiform discharges. Sodium bromide exerts significant anticonvulsant effects by enhancing GABA-ergic inhibitory functions, such as increasing the amplitude of inhibitory postsynaptic currents and paired-pulse inhibition. Sodium bromide specifically enhances stimulation-induced extracellular alkalosis without affecting baseline pH or subsequent acidosis processes. Sodium bromide exhibits species-specific pharmacokinetic characteristics, competes with chloride ions for renal tubular reabsorption sites, and serves as a marker for extracellular fluid volume. Sodium bromide can be used in the research of epilepsy and related neurological diseases .
