Huh-7/hNTCP cells were infected with in vitro generated HDV in the presence or absence of MyrB (50 nM) or lonafarnib (200 nM). After 5 days cells were labeled with HDAg#280, secondary AF488 and stained with DAPI. A representative of four independent experiments is shown.

Low-dose lonafarnib decreased HIF-1α expression without inhibiting cell growth in MDA-MB-231 cells. (A, B) Lonafarnib (1 μM) treatment for 24 h significantly decreased HIF-1α expression, which was normalized to that of GAPDH. In contrast, lonafarnib (1 μM) did not decrease HIF-2α expression.

SCH66336 at concentration ranging from 0.1 μM to 8 μM suppress growth and induce apoptosis of human head and neck squamous carcinoma cells (HNSCC) in a dose and time dependent manner. SCH66336 (8 μM) suppresses protein kinase B/Akt activity as well as the phosphorylation of the Akt substrates glycogen synthase kinase (GSK)-3β, forkhead transcription factor, and BAD in SqCC/Y1 cells. [2] SCH66336 demonstrate variable antiproliferative effects against the cell lines, with IC50 ranging from 0.6 μM to 32.3 μM. [3] Lonafarnib induces a CCAAT/enhancer-binding protein homologous protein (CHOP)-dependent transactivation of the DR5 promoter, thus induces CHOP-dependent DR5 up-regulation. Lonafarnib (< 10 μM) activates caspase-8 and its downstream caspases, thus induces caspase-8-dependent apoptosis in H1792 cells. Lonafarnib (5 μM) up-regulate DR5 expression, increase cell-surface DR5 distribution, and enhance tumor necrosis factor-related apoptosis-inducing ligand-induced apoptosis in H1792 cells.[4] |

| In vivo | SCH66336 inhibits HTBI77 human lung carcinoma xenograft growth in nude mice in a dose-dependent fashion. [1] SCH66336 dosed at 50 mg/kg p.o. bid by oral gavage inhibits tumor growth with up to 69% growth inhibition after 21 days of treatment in NOD/SCID mice bearing s.c. flank XEN01, XEN05 or XEN08 GBM xenografts.

Bio Calculators
Molarity Calculator
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 MSDS / COA (available on product pages).
Dilution Calculator
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 MSDS / 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.
