A23187 is a Ca2+ ionophore that exhibits pro-inflammatory and allergic activities. In cardiomyocytes, A23187 induces formation of endothelial microvesicles, increasing leakage of lactate dehydrogenase and decreasing cell viability. A23187 also induces mast cell degranulation and increases production of TNF-α. In spermatozoa, this compound induces the acrosome reaction, allowing fertilization to occur in the absence of PKA activation.
