T-2307 is an antifungal agent with blood-brain barrier penetration. T-2307 exhibits broad-spectrum antifungal activity against Candida species, including echinocandin-resistant strains, Cryptococcus neoformans, Cryptococcus gattii, and some Aspergillus species. T-2307 selectively targets fungal mitochondrial respiratory chain complexes III and IV, causing collapse of the fungal mitochondrial membrane potential and exerting fungicidal or fungistatic effects. T-2307 can be used in research related to fungal infections such as invasive candidiasis, cryptococcosis, and aspergillosis.

Stock Solution Working Solution

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.

Protocol 1

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.5 mg/mL (5.71 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.

All Signal Pathway Related Cell Biology

Mitochondrial membrane-potential fluorescent assay
Mitochondrial membrane potential fluorescent assays estimate ΔΨm in living cells using lipophilic cationic dyes such as TMRM, TMRE, rhodamine 123, and JC-1, which accumulate in mitochondria according to membrane polarization; loss of signal after FCCP or CCCP treatment is interpreted as mitochondrial depolarization. TMRM/TMRE and rhodamine 123 are commonly used for semi-quantitative live-cell microscopy or flow cytometry, while JC-1 can report a shift from red aggregate fluorescence to green monomer fluorescence during depolarization; interpretation requires controls because dye concentration, quenching mode, cell type, dye efflux, and mitochondrial mass can affect fluorescence independently of ΔΨm.
Fluorescent plasma-membrane potential dye assay
Fluorescent plasma-membrane potential dye assays measure changes in cell membrane potential using voltage-sensitive dyes whose fluorescence changes when cells depolarize or hyperpolarize. Anionic bis-oxonol dyes such as DiBAC4(3) enter depolarized cells more readily and show increased fluorescence after intracellular binding, while hyperpolarization reduces dye accumulation and fluorescence. FMP/FLIPR membrane-potential dyes are used for faster, homogeneous microplate assays of ion-channel or receptor-mediated membrane-potential changes.
Mitochondrial membrane-potential and mitochondrial mass staining
Mitochondrial membrane potential staining measures the electrochemical polarization across the mitochondrial inner membrane in live cells using lipophilic cationic fluorescent probes; early rhodamine-based work showed that selective mitochondrial dye accumulation is lost when the mitochondrial transmembrane potential is dissipated. JC-1 reports mitochondrial polarization by shifting from green monomer fluorescence to red J-aggregate fluorescence as dye concentration increases within energized mitochondria; therefore, the red/green fluorescence ratio is used as a relative readout of mitochondrial membrane potential. TMRE or TMRM staining provides a single-channel relative readout because these cationic rhodamine esters accumulate in polarized mitochondria, and lower fluorescence indicates reduced mitochondrial polarization when acquisition and dye-loading conditions are controlled. Mitochondrial mass staining is commonly performed with MitoTracker Green FM or related MitoTracker dyes as

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
