Description

NCT-505 is a potent and selective aldehyde dehydrogenase (ALDH1A1) inhibitor, with an IC50 of 7 nM, and weakly inhibits hALDH1A2, hALDH1A3, hALDH2, hALDH3A1 (IC50s, >57, 22.8, 20.1, >57 μM).

IC50 & Target

ALDH1

 

In Vitro

NCT-505 (Compound 86) is a potent and selective aldehyde dehydrogenase (ALDH1A1) inhibitor, with an IC50 of 7 nM, and weakly inhibits hALDH1A2, hALDH1A3, hALDH2, hALDH3A1 (IC50s, >57, 22.8, 20.1, >57 μM). NCT-505 has no obvious inhibitory effec on 5-hydroxyprostaglandin dehydrogenase (HPGD) and type-4 hydroxysteroid dehydrogenase (HSD17β4) (IC50, >57 μM). Moreover, NCT-505 shows potent cellular activities, reducing the viability of OV-90 cells with an EC50 of 2.10-3.92 μM. NCT-505 is also cytotoxic to SKOV-3-TR cells, with IC50s of 1, 3, 10, 20, 30 μM, respectively, in the titration assay[1].

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 (4.79 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% Corn Oil

    Solubility: ≥ 2.5 mg/mL (4.79 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 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay
[1]

Cells are harvested, and an equal volume of first compound (NCT-505 or paclitaxel (Taxol)) at the indicated concentration or vehicle DMSO (final DMSO concentration is the same in all conditions) is added to the cell suspension before dispensing. Cells are dispensed into 384-well, white, TC-treated plates at a density of 3000 cells/well in a volume of 30 μL of growth media/well using a Multidrop Combi dispenser. Immediately after dispensing, the second compound (ALDH1A1 inhibitor or paclitaxel) and control solutions (92 nL) are transferred using a pintool. Plates are covered with a breathable seal and incubated for 4 days at 37°C, 5% CO2, 85% RH followed by addition of 20 μL of CellTiter-Glo. After a ∼30 min incubation at rt, samples are analyzed for luminescence intensity using a ViewLux high-throughput CCD imager equipped with clear filters. Pinned compounds are tested as 16-point dilution series, with concentrations ranging from 30.7 μM to 70.1 nM for ALDH1A1 inhibitors (NCT-505, etc.) or 31.7 μM to 0.034 nM for paclitaxel, in triplicate. Data are normalized to positive control bortezomib (1 μM final) and neutral control DMSO[1].

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.
