Ionomycin (SQ23377) is a potent, selective calcium ionophore and an antibiotic produced by Streptomyces conglobatus. Ionomycin (SQ23377) is highly specific for divalent cations (Ca>Mg>Sr=Ba). Ionomycin (SQ23377) promotes apoptosis. Ionomycin also induces the activation of protein kinase C (PKC)[1][2][3].

体外研究 (In Vitro)
Ionomycin is a Calcium ionophore and an antibiotic produced by Streptomyces conglobatus[1]. Addition of 2 μM Ionomycin to LCLC 103H cells causes an instantaneous increase in intracellular Ca2+ concentration from 50 to 180 nM. DNA and protein analysis in Ionomycin-treated cultures revealed DNA fragmentation and PARP cleavage to an 85-kDa fragment typical of caspase-mediated apoptosis. Necrosis could be detected in ~1-5% of the Ionomycin treated cells. Caspase activation in whole cells was followed by monitoring the increase in activity against Ac-DEVD-amc following Ionomycin treatment[2]. Ionomycin-mediated cleavage and exosome release. Following Ionomycin exposure, medium conditioned by SKOV3ip cells had increased amounts of exosomes containing the L1-32 cleavage fragment[4].
