Description: Rimiducid, also known as AP1903, is a lipid-permeable bivalent "dimerizer" drug that binds FKBP and induces Fas cross-linking. AP1903 induced iCasp9 activation, which led to the apoptosis of specific undifferentiated PSCs in vitro and in vivo. AP1903 elicites potent and dose-dependent apoptosis of cells in culture expressing dimerizer-dependent Fas constructs, with an EC50 of ≈0.1 nM. Intravenous administration of AP1903 produces cross-linking of the drug-binding domains of this chimeric protein, which in turn dimerizes caspase9 and activates the downstream executioner caspase 3 molecule, resulting in cellular apoptosis.

Additional Information

AP1903 was discovered and developed by ARIAD scientists, as a part of ARIADÂ’s ARGENT™ technology platform which combines chemistry and genetics to allow specific cell-signaling and gene-expression events to be chemically activated in whole animals and cultured cells. The technology platform includes a portfolio of distinct small-molecule "dimerizer" compounds optimized for specific applications. Dimerizers bring specific proteins together in cells.   (source: http://www.ariad.com/wt/tertiarypage/AP1903).
