    Description

    A 922500 (DGAT-1 Inhibitor 4a) is a potent, selective, and orally bioavailable diacylglycerol acyltransferase 1 (DGAT-1) inhibitor with IC50s of 9 and 22 nM against human and mouse DGAT-1, respectively.

    IC50 & Target

    IC50: 9 nM (human DGAT-1), 22 nM (mouse DGAT-1)[1]

    In Vitro

    A 922500 (A-922500) demonstrates excellent selectivity over other acyltransferases, including DGAT-2 (IC50=53 μM) and the phylogenetic family members acyl coenzyme A cholesterol acyltransferase-1 and -2 (IC50=296 μM) [1].

    In Vivo

    DGAT-1 inhibitor A 922500 (A-922500) reduces serum triglyceride levels from baseline at all doses tested; however, this is only statistically significant at the 3 mg/kg dose, which lowers serum triglycerides by 53%. Similarly, the 3 mg/kg dose of A 922500 significantly reduces serum FFA concentrations by 55% and total cholesterol by 25%. DGAT-1 inhibition has no significant effect on body weight at any dose tested. Although A 922500 dpes not significantly affect LDL-cholesterol or HDL-cholesterol individually, the serum LDL/HDL-cholesterol ratio is significantly improved by A 922500 at 0.3 and 3 mg/kg. Similar to the dyslipidemic hamster, treatment with 3 mg/kg A 922500 significantly reduces serum triglyceride concentrations (39%). FFA levels significantly increase over the 14-day period in vehicle-treated animals. This increase is inhibited in a dose-dependent manner by A 922500 such that FFA concentrations are 32% lower after 14 days of treatment with the DGAT-1 inhibitor at 3 mg/kg, compared with the vehicle group (p < 0.05). HDL-cholesterol is significantly increased from baseline levels by A 922500 at 0.3 and 3 mg/kg; however, this is only significantly increased compared with vehicle at the 3 mg/kg dose. Body weight significantly increases over the 2-week period in vehicle-treated rats, and this is not affected by A 922500. LDL-cholesterol is significantly reduced in the vehicle treated group. DGAT-1 inhibition does not further reduce LDL-cholesterol and has no effect on total cholesterol[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 (5.83 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.

    For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
    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.

    Animal Administration
    [1]

    Mice and Hamsters[1]
    Thirteen-week-old male Golden Syrian hamsters (n=40), initially weighing approximately 140 g, are used. Ten-week-old Male Zucker fatty rats (n=32), weighing between 270 and 330 g, are used. After collection of baseline lipid profiles, hyperlipidemic hamsters (n=10/group) and Zucker fatty rats (n=8/group) are administered vehicle [20:80 (v/v), polyethylene glycol/hydroxypropyl-β-cyclodextrin (10% w/v)] or DGAT-1 inhibitor A 922500 (A-922500) at 0.03, 0.3, and 3 mg/kg, once daily by oral gavage. The dosing volume is 5 mL/kg. Serum lipid profiles are then measured 3 h after the dose on day 7 and day 14. Hamsters continue to be fed a high-fat diet with 10% fructose in the drinking water throughout the treatment period. Zucker fatty rats remain on standard rodent diet throughout the study.

    • 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.
