产品描述 | Calcimycin (A-23187) is an ionophorous, polyether carboxylic antibiotic from Streptomyces chartreusensis. It binds and transports calcium and other divalent cations across membranes and uncouples oxidative phosphorylation while inhibiting ATPase of rat liver mitochondria. The substance is used mostly as a biochemical tool to study the role of divalent cations in various biological systems. |
体外活性 | Calcimycin 通过激发细胞内钙调控的自噬以 P2RX7 依赖的方式介导杀灭分枝杆菌[4]。 |
体内活性 | Calcimycin (2.5或7.5 nM; 胸膜内注射) 诱导蛋白质渗漏[5]。 |
