产品介绍

Calcimycin(A-23187)hemimagnesium是一种抗生素和独特的二价阳离子离子载体(divalentcationionophore)，如钙离子和镁离子。Calcimycinhemimagnesium通过增加细胞内钙浓度诱导Ca2+依赖性细胞死亡。Calcimycinhemimagnesium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)。

产品描述	Calcimycin (A-23187) hemimagnesium is an antibiotic and a unique divalent cation ionophore (like calcium and magnesium). Calcimycin hemimagnesium induces Ca2+-dependent cell death by increasing intracellular calcium concentration. Calcimycin hemimagnesium inhibits the growth of Gram-positive bacteria and some fungi. Calcimycin hemimagnesium also inhibits the activity of ATPase and uncouples oxidative phosphorylation (OXPHOS) of mammalian cells. Calcimycin hemimagnesium induces apoptosis[1][2][3][4]. Calcimycin (A-23187) hemimagnesium mediates mycobacterial killing by inducing intracellular calcium-regulated autophagy in a P2RX7 dependent manner[4].
