Description

L-778123 hydrochloride is a dual inhibitor of FPTase and GGPTase-I, with IC₅₀ values of 2 nM and 98 nM respectively.

In Vitro

L-778123 hydrochloride alone does not have obvious cytotoxicity on HT-29 and A549 cell lines (IC₅₀: >100 μM), but can generate synergistic effects with Doxorubicin (HY-15142A), with the decreased IC₅₀s of 1.72 and 1.52 μM respectively^[2].
L-778123 hydrochloride inhibits myeloid leukemia cell proliferation with IC₅₀ values of 0.2 μM-1.8 μM for cell lines, and 0.1 μM-161.8 μM in primary samples^[3].
L-778123 (0-1 μM, 12 h; or 5 μM, 6 h) hydrochloride inhibits H-RAS prenylation in HL-60 cells, and inhibits phosphorylated MEK-1/2 level (5 μM, 24 h)^[3].
L-778123 (0-100 μM, 72 h) hydrochloride inhibits lymphocyte activation (marker: CD71 or CD25) and function in human PBMCs^[4].

In Vivo

L-778123 (50 mg/kg/day, infusion, 7 days) hydrochloride inhibits both HDJ2 and Rap1A prenylation in PBMCs of dogs, but without inhibition in Ki-Ras prenylation^[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: ≥ 2.25 mg/mL (5.09 mM); Clear solution

This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 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: ≥ 2.25 mg/mL (5.09 mM); Clear solution

This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.25 mg/mL (5.09 mM); Clear solution

This protocol yields a clear solution of ≥ 2.25 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 (22.5 mg/mL) to 900 μL Corn oil, and mix evenly.

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.

Protocol 1

Add each solvent one by one: PBS
Solubility: 100 mg/mL (226.07 mM); Suspended solution; Need ultrasonic and adjust pH to 5 with 1M HCl
