|Description||LB42708 is an orally active farnesyltransferase (FTase) inhibitor with IC50 of 0.8, 1.2, and 2.0 nM toward H-ras, N-ras, and K-ras, respectively.|
LB42708 potently inhibits the processing of the cellular farnesylated protein p21ras induced by LPS + IFN-γ in murine macrophage cell line RAW264.7 cells. LB42708 inhibits NF-κB activation and iNOS promoter activity through the inhibition of IKK activity. Moreover, LB42708 suppresses the expression of inducible NO synthase, cyclooxygenase-2, TNF-alpha, and IL-1beta and the production of NO and PGE(2) in immune-activated macrophages and osteoblasts.  LB42708 irreversibly inhibits growth and induces apoptosis in H-ras and K-ras-transformed rat intestinal epithelial cells.  LB42708 inhibits of VEGF-induced tumor angiogenesis by blocking Ras-dependent MAPK and PI3K/Akt pathways in tumor-associated endothelial cells. 
|In vivo||LB42708 (12.5 mg/kg i.p.) inhibits production of NO, PGE2, TNF-α, and IL-1β in LPS-injected mice, and also prevents the development of CIA.  LB42708 (20 mg/kg/day i.p.) also inhibits tumor growth and angiogenesis in both Ras wild-type and mutated tumors. |
|In vitro||DMSO||100 mg/mL (180.03 mM)|
|Ethanol||'86 mg/mL warmed|
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
