Description

Amsilarotene (TAC-101; Am 555S), an orally active synthetic retinoid, has selective affinity for retinoic acid receptor α (RAR-α) binding with Ki of 2.4, 400 nM for RAR-α and RAR-β. Amsilarotene induces the apoptotic of human gastric cancer, hepatocellular carcinoma and ovarian carcinoma cells. Amsilarotene can be used for the research of cancer[1][2][3].

In Vitro

Amsilarotene (0, 10, 25 μM; 24 hours) induces apoptosis of human epithelial ovarian carcinoma-derived cell lines in a concentration-dependent manner[2].
Amsilarotene (10, 20 μM; 0, 3, 6, and 9 days) inhibits the proliferation of BxPC-3 and MIAPaCa-2 cells[3].
Amsilarotene (10 μM; 48 hours) increases the proportion of sensitive BxPC-3 cells in the G1 phase[3].
Amsilarotene (10 μM; 0, 3, 6, 24, 48, 72 hours) inhibits the retinoblastoma-gene product (RB) phosphorylation in BxPC-3 cells between 24 and 72 hours[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay[3]

Cell Line: BxPC-3, MIAPaCa-2, AsPC-1 cells
Concentration: 10 and 20 μM
Incubation Time: 0, 3, 6, and 9 days.

Cell Cycle Analysis[3]

Cell Line: Sensitive BxPC-3 cells
Concentration: 10 μM
Incubation Time: 48 hours

In Vivo

Amsilarotene (8 mg/kg/day orally for 30 days) inhibits the RMG-II tumor growth in nude mice[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 6-week-old female BALB/c nu/nu mice with subcutaneous RMG-II tumors[2]
Dosage: 8 mg/kg/day
Administration: Orally for 30 days
Result: The maximal tumor growth-inhibiting effect was seen on day 31 of administration, when there was a 45% reduction of relative tumor volume (RTV).

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (6.48 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (6.48 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    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.
