IC50: 5 nM for F36V-FKBP in competition fluorescence polarization assay
FKBP ligand homodimers can be used to trigger signaling events inside cells and animals that have been engineered to express fusions between and FKBP appropriate signaling domains. However, use of these dimerizers in vivo is potentially limited by ligand binding to endogenous FKBP. AP1903 is a homodimer of the modified ligand for FKBP.
In vitro: By selective inhibition of FKBP, AP1903 elicited potent and dose-dependent apoptotic death of the human fibrosarcoma line HT1080 engineered cells in culture, with an EC50 of ~0.1 nM [1].
In vivo: In an mouse model of conditional cell ablation, animals were i.v. treated with various doses of AP1903, and then serum hGH levels were determined as a measure of the number of surviving cells. Results showed that AP1903 elicited a dose-dependent decrease in levels of serum hGH, with a half-maximal effective dose of 0.4 mg/kg [1].
Clinical trials: In an intravenous, single-blind, placebo- and saline-controlled, ascending-dose study, AP1903 was shown to be safe and well tolerated at all dose levels and demonstrated a favorable PK profile at doses well above the anticipated therapeutic dose [2].

FKBP Binding Assay |
Subsaturating concentrations of protein were incubated for 30 min with 2.5 nM fluoro-FK506 and serial dilutions of competitor ligand in the wells of a Dynatech microfluor plate. Polarization was read on a Jolley FPM-2 (Jolley Consulting and Research, Grayslake, IL). The increase in polarization on binding was used as a direct readout of percentage of bound probe, compared with controls containing no competitor (100%) or no protein (0%). The concentration of competitor resulting in a 50% probe displacement (IC50) was determined by a nonlinear least square fit by using the four-parameter algorithm. |

|
Preparation method |
Limited solubility. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |

|
Applications |
The human fibrosarcoma line HT1080 was engineered to express stably a fusion protein comprising a myristoylation sequence, two copies of F36V-FKBP, and the human Fas intracellular domain. AP1903 elicits potent and dose-dependent apoptotic death of these engineered cells in culture, with an EC50 of ≈0.1 nM. |

Preparation method |
Formulated in [50% N,N-dimethylacetamide/50% (90% PEG-400/10% Tween 80)] at 2 ml/kg |
|
Applications |
Male nu/nu mice were injected with HT1080 cell line expressing a Fas-F36V-FKBP construct that also constitutively secretes hGH. AP1903 exhibits a dose-dependent decrease in serum hGH levels, with a half-maximal effective dose of 0.4 ± 0.1 mg/kg. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
