Calcimycin (Synonyms: A-23187; Antibiotic A-23187) 纯度: 99.56%

Calcimycin (A-23187) 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 通过增加细胞内钙浓度诱导 Ca2+ 依赖性细胞死亡。Calcimycin 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。

生物活性

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

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 three hours after 7.5 nM, challenge the protein levels in the pleural cavity were equivalent to about a half of their corresponding peak values.
