OncoACP3 TFA
Based on 1 Customer Validation
OncoACP3 TFA is a small-molecule ligand of prostatic acid phosphatase (ACP3) with an IC50 of 0.30 nM. OncoACP3 TFA has a modular structure that supports flexible payload delivery. After radiolabeling with Lu-177 it selectively accumulates in ACP3-expressing tumors with a long retention time, enabling targeted radiation delivery. OncoACP3 TFA is applicable to research related to prostate cancer.

Biological Activity
OncoACP3 TFA binds to human recombinant ACP3 with ultra-high affinity, with a dissociation rate of 1.2 × 10-4 s-1[1].
177Lu-OncoACP3 TFA specifically binds to HT1080.hACP3 and PC3.hACP3 cells expressing ACP3, but does not bind to ACP3-negative wild-type cells[1].
177Lu-OncoACP3 TFA specifically localizes to the membranes of HT1080.hACP3 and PC3.hACP3 cells that express ACP3, but does not bind to wild-type cells without ACP3 expression[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
OncoACP3 TFA is conjugated to the cytotoxic agent MMAE (HY-15162) via a cleavable linker to construct the small-molecule drug conjugate OncoACP3 TFA-GlyPro-MMAE, which enables targeted chemotherapy in mouse models[1].

-
Dosage:62.5 nmol/kg
-
Administration:i.v.; single injection
-
Result:Exhibited a tumor half-life of ~72 hours in female mice with HT1080.hACP3 tumors.

Animal Model:Athymic BALB/c AnNRj-Foxn1 nude mice (subcutaneous flank implantation of HT1080.hACP3 or PC3.hACP3 cells)[1]
-
Dosage:250 nmol/kg
-
Administration:i.v.; repeated injections as scheduled
-
Result:Delivered ~150 pmol/g of MMAE to HT1080.hACP3 tumors and ~15 pmol/g of MMAE to PC3.hACP3 tumors at 24 hours post-administration, with minimal MMAE accumulation in healthy organs.
Significantly inhibited tumor growth in both HT1080.hACP3 and PC3.hACP3 tumor models compared to vehicle or non-cleavable OncoACP3-MMAE, with greater efficacy observed in the HT1080.hACP3 model.

Select the appropriate dissolution method based on your experimental animal and administration route.
- 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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (1.89 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (1.89 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
