Description
Rimiducid (AP1903) is a dimerizer agent that acts by cross-linking the FKBP domains. Rimiducid (AP1903) dimerizes the Caspase 9 suicide switch and rapidly induces apoptosis.
IC50 & Target
EC50: 0.1 nM (FKBP, in HT1080 cells)[1]
Fas receptor[1]
In Vitro
Rimiducid (AP1903) elicits potent and dose-dependent apoptotic death of these engineered cells in culture, with an EC50 of ≈0.1 nM[1]. Maximal killing occurred in the presence of 3 to 10 nM Rimiducid (AP1903), and the IC50 is approximately 0.2 nM. LV′VFas-transduced T lymphocytes expressing high levels of CD25 (top panel) are eliminated by with 66%±7.5% (n=10) efficiency. When cells are examined after CD25 expression returned to basal levels, 63%±4.7% (n=9) killing is observed after Rimiducid treatment[2].

Please refer to the solubility information to select the appropriate solvent. The compound is unstable in solutions, freshly prepared is recommended.
For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day. The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Protocol 1
Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (1.77 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μLDMSO stock solution (25.0 mg/mL) to 900 μLCorn oil, and mix evenly.
Solubility: 2 mg/mL (1.42 mM); Suspended solution; Need ultrasonic

Cell Assay
[1][2]
Cloned HT1080 cell lines (ATCC CCL-121) retrovirally transduced with Fas constructs are prepared. Cell viability after overnight incubation with Rimiducid (0.01 nM, 0.1 nM, 1 nM, 10 nM, 100 nM, 1000 nM) is measured by Alamar Blue assay[1].
For annexin V assays, sorted LV′VFas-transduced T cells (2×106 cells/mL) are incubated with 10 nM Rimiducid. Analyzed by flow cytometry[2].

Animal Administration
[1]
Mice[1] Male nu/nu mice are used. For injection, HTFasGH-3 cells are harvested from tissue culture dishes in PBS/0.1% glucose/10 mM EDTA, washed, and resuspended in PBS/0.1% BSA/0.1% glucose at a concentration of 2×107 cells/mL. Between 2 and 4×106 cells are implanted into two i.m. sites. After 24 h, mice are administered i.v. Rimiducid at 2 mL/kg. After a further 24 h mice are killed and serum human GH concentrations are determined by ELISA.

Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
