LB42708 (LB-42708; LB 42708) is a novel, potent, orally bioactive, and nonpeptidic farnesyltransferase (FTase) inhibitor with potential anti-inflammatory activity. It inhibits H-ras, N-ras, and K-ras with IC50 of 0.8, 1.2, and 2.0 nM, respectively. LB42708 demonstrates significant in vivo efficacy in mice collagen-induced arthritis model.
| ln Vitro |
LB42708, in spite of K-ras prenylation, causes cell death. In H-ras-transformed RIE cells, LB42708 causes growth inhibition, which is accompanied by G1/M and G2/M cell cycle arrests, respectively. Ras-transformed rat intestinal epithelial (RIE) cells exhibit unique morphological changes and cell cycle arrest as a result of p21(CIP1/WAF1) and RhoB being upregulated above the basal level by LB42708[2].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.50 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2.5 mg/mL (4.50 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (4.50 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

| 5 mM | 0.3601 mL | 1.8003 mL | 3.6006 mL | |
| 10 mM | 0.1800 mL | 0.9002 mL | 1.8003 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
