MedKoo CAT#: 571087

CAS#: 52665-69-7

Description: Calcimycin 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. Calcimycin was identified as a transcriptional inhibitor of a target gene in colon cancer pathways. In addition, it is used in human fertility treatments.
