Catalog Number: 1234
Alternate Names: Calcimycin
Chemical Name: 5-(Methylamino)-2-[[2R,3R,6S,8S,9R,11R) -3,9,11-trimethyl-8-[(1S)-1-methyl-2-oxo-2-(1H-pyrrol-2-yl)-ethyl]-1,7-dioxaspiro[5.5]undec-2-yl]methyl]-4-benzoxazolecarboxylic acid
Biological Activity
Calcium ionophore that induces Ca2+-dependent cell death by increasing intracellular calcium concentration. Promotes intracelllular ROS generation and platelet particle formation (fragmentation) in vitro and in vivo. Can be used to induce autophagy in mammalian cells.
