Biochem/physiol Actions

Rimiducid (AP1903) is a homodimeric FKBP12 Phe36Val (F36V-FKBP, FKBP-F36V) mutant-selective cross-linker composed of two high-affinity ligands, each with 713-fold selectivity over endogenous FKBP (Kd = 94 pM/F36V- vs 67 nM/Wt-FKBP using 4′-AF-labeled rimiducid). Rimiducid activates signaling events via Chemical Induction of Dimerization (CID) by cross-linking FKBP12-F36 fusions (Chimeric Antigen Receptor or CAR) expressed in cells in cultures (apoptosis induction EC50 = 0.1 nM; HT1080 expressing FKBP(F36V)-Fas intracellular domain) and in animals in vivo (EC50 = 0.4 mg/kg i.v. in a murine model of conditional cell ablation).

Graft-versus-host disease (GVHD) is a major complication of allogeneic bone marrow transplantation. One strategy to treat GVHD is to equip donor T cells with a conditional suicide mechanism that can be triggered when GVHD occurs. The herpes simplex virus thymidine

FKBP ligand homodimers can be used to activate signaling events inside cells and animals that have been engineered to express fusions between appropriate signaling domains and FKBP. However, use of these dimerizers in vivo is potentially limited by ligand binding
