Rimiducid (AP1903) is a chemical protein dimerizer and binds tightly to the target FKBP fusion protein while binding minimally to the abundant natural FKBP. Rimiducid elicites potent and dose-dependent apoptosis of cells in culture expressing dimerizer-dependent Fas constructs, with an EC50 of ≈0.1 nM.
