A23187 Usage And Synthesis

Chemical Propertieswhite to off-white solid
UsesCalcimycin is a potent calcium ionophore isolated from Streptomyces chartreusis in 1974. Calcimycin is a spiroketal substituted by pyrollic and benzoxazolyl groups which afford its high affinity and selectivity for calcium. Calimycin exhibits broad biological activity against bacteria, fungi and protozoa. It has found wide application as a research tool for calcium-regulated cellular events.
Biological ActivityCalcium ionophore that induces Ca 2+ -dependent cell death by increasing intracellular calcium concentration. Promotes intracelllular ROS generation and platelet particle formation (fragmentation) in vitro and in vivo .
Purification MethodsIt recrystallises from Me2CO as colourless needles. Protect it from light and moisture, store in a refrigerator. It is soluble in Me2SO or EtOH and can be stored for 3 months without loss of activity. The Mg and Ca salts are soluble in organic solvents and cross biological membranes. It has a pKa of 6.9 in 90% Me2SO. The Ca complex crystallises from 50% EtOH as colourless prisms. It is highly TOXIC. [Pressman Ann Rev Biochem 45 501 1976, Chaney et al.
