Xestospongin C
Based on 11 publication(s) in Google Scholar
Xestospongin C ((-)-Xestospongin C) is a selective, reversible inositol 1,4,5-trisphosphate receptor (IP3R) inhibitor. Xestospongin C acts as an inhibitor of the sarcoplasmic/endoplasmic reticulum Ca2+ ATPase (SERCA) pump of internal stores. Xestospongin C blocks IP3-induced Ca2+ release from cerebellar microsomes with an IC50 of 358 nM. Xestospongin C is a valuable tool for investigating the structure and function of IP3Rs and Ca2+ signaling in neuronal and nonneuronal cells.

In Vitro
Xestospongin C (XeC; 10 μM; 1 h before Aβ) pretreatment before Aβ1-42 (20 μM; 24 hours) application displays a significant decrease in the early apoptotic rate (9.87%) compared to the Aβ alone treated group (18.38%)[1].
Xestospongin C (10 μM; 1 h before Aβ) and Aβ1-42 (20 μM; 100 s) has significant main effects on the peak value and average values of Ca2+ changes, as well as a significant interaction in primary cultured hippocampal neurons[1].

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.
-
Ca2+ Staining Technique
Ca2+ staining is an experimental technique that utilizes specific fluorescent probes (such as Fluo-4 AM, Fura-2, etc.) to qualitatively or quantitatively detect dynamic changes in intracellular Ca2+ concentrations; this is achieved by monitoring the changes in fluorescent signals generated when these probes bind to free intracellular calcium ions. The underlying principle relies primarily on the presence of chelating groups within the probe's molecular structure that possess high affinity for calcium ions.
