生物活性

Calcimycin hemicalcium salt (A-23187 hemicalcium salt) is an antibiotic and a unique divalent cation ionophore (like calcium and magnesium). Calcimycin hemicalcium salt induces Ca2+-dependent cell death by increasing intracellular calcium concentration. Calcimycin hemicalcium salt inhibits the growth of Gram-positive bacteria and some fungi. Calcimycin hemicalcium salt also inhibits the activity of ATPase and uncouples oxidative phosphorylation (OXPHOS) of mammalian cells. Calcimycin hemicalcium salt induces apoptosis[1][2][3][4].

体外研究
(In Vitro)

Calcimycin hemicalcium salt (A-23187 calcium) mediates mycobacterial killing by inducing intracellular calcium-regulated autophagy in a P2RX7 dependent manner[4].

体内研究
(In Vivo)

Calcimycin hemicalcium salt (A-23187 calcium) (2.5 or 7.5 nM; intrapleurally) induces protein leakage[5].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Mice (ICR, 25-30 g)[5]
Dosage: 2.5 or 7.5 nM
Administration: Intrapleurally
Result: Two hours after 2.5 nM, or 3 hours after 7.5 nM, challenge the protein levels in the pleural cavity were equivalent to about a half of their corresponding peak values.
