A-23187 hemicalcium salt
Antibiotic A-23187 hemicalcium salt

Calcimycin hemicalcium salt (A-23187 hemicalcium salt) 是一种抗生素和独特的二价阳离子离子载体 (divalent cation ionophore)，如钙离子和镁离子。Calcimycin hemicalcium salt 通过增加细胞内钙浓度诱导 Ca²⁺依赖性细胞死亡。Calcimycin hemicalcium salt 抑制革兰氏阳性细菌和一些真菌的生长，还抑制 ATP 酶的活性并解耦哺乳动物细胞的氧化磷酸化 (OXPHOS)，诱导细胞凋亡 (apoptosis)。

生物活性

Calcimycin hemicalcium salt (A-23187 hemicalcium salt) is anantibioticand a uniquedivalent 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 inducesapoptosis^[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].

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.
