Naphazoline nitrate
Based on 2 publication(s) in Google Scholar
Naphazoline (Naphthazoline) nitrate is an α-adrenergic receptor agonist. Naphazoline nitrate reduces vascular hyperpermeability and promotes vasoconstriction. Naphazoline nitrate reduces the levels of inflammatory factors (TNF-α, IL-1β and IL-6), cytokines (IFN-γ and IL-4), IgE, GMCSF, and NGF. Naphazoline nitrate can be used for non-bacterial conjunctivitis research.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (9.15 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

PC12 NGF-Induced Neuronal Differentiation Culture
PC12 cells are a rat adrenal pheochromocytoma clonal line that responds to NGF by stopping proliferation and extending branching neurite-like processes; after longer NGF exposure, cells develop long processes and neuronal-like ultrastructural and functional features. NGF-induced differentiation is read out mainly by neurite outgrowth, reduced proliferation, microtubule assembly, and neuronal differentiation-associated proteins such as MAPs, tau, GAP-43, and synapsin-1.

PC12 NGF-induced neuronal-like differentiation
PC12 cells are a rat adrenal pheochromocytoma-derived clonal cell line that responds to nerve growth factor by stopping proliferation and extending neurites, producing a sympathetic neuron-like phenotype used to study neuronal differentiation and neurite outgrowth. NGF acts through TrkA-dependent signaling, and neurite outgrowth is associated with ERK/Akt signaling, microtubule organization, neuronal-marker expression, and increased electrophysiological neuronal features such as sodium-channel density. The main assay readout is morphological differentiation, usually measured as the percentage of neurite-bearing cells, neurite length, neurite number, or total neurite length per cell. Additional readouts include GAP-43, tyrosine hydroxylase, βIII-tubulin, neurofilament, synapsin I, synaptophysin, ERK phosphorylation, Akt phosphorylation, and sodium-channel current density.

Pyroptosis Solutions
Pyroptosis is a lytic inflammatory cell-death pathway executed by gasdermin pores, most classically through inflammasome-mediated activation of caspase-1, cleavage of gasdermin D, membrane pore formation, LDH release, and secretion of IL-1β and IL-18. The canonical pathway is commonly modeled by priming cells with an inflammatory signal such as LPS to induce pro-IL-1β and inflammasome components, followed by an activation signal such as ATP or nigericin to activate NLRP3, ASC speck formation, caspase-1 cleavage, GSDMD cleavage, cytokine release, and pyroptotic membrane rupture. The non-canonical pathway is triggered when cytosolic LPS activates mouse caspase-11 or human caspase-4/5, leading to GSDMD cleavage and pyroptosis, and this can secondarily activate NLRP3-dependent IL-1β release. Pyroptosis is linked to inflammatory injury, infection, cancer, liver disease, ocular disease, placental inflammation, and other disease phenotypes, but unresolved questions include which gasdermin fam
