Biological Activity

Description

Lonafarnib (SCH66336) is an orally bioavailable FPTase inhibitor for H-ras, K-ras-4B and N-ras with IC50 of 1.9 nM, 5.2 nM and 2.8 nM in cell-free assays, respectively. Phase 3.

Targets

H-ras ^[1] (Cell-free assay)	N-ras ^[1] (Cell-free assay)	K-ras-4B ^[1] (Cell-free assay)
1.9 nM	2.8 nM	5.2 nM

In vitro
In vitro	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]
Cell Research	Cell lines	UMSCC10B, UMSCC14B, UMSCC17B, UMSCC22B, and UMSCC35, UMSCC38 cell lines
	Concentrations	0.1 μM - 8 μM
	Incubation Time	24 hours
	Method	The cells are seeded in 96-well cell-culture cluster plates at a density that allowed control cultures to grow exponentially for 5 days. After 24 hours, the cells are treated with different concentrations of SCH66336. SCH66336 is dissolved in DMSO. Control cultures received the same amount of DMSO as the treated cultures do. Cell numbers are estimated after 5 days of treatment by SRB assay. The percentage of growth inhibition is calculated by using the equation: percentage growth inhibition = (1 − At/Ac) × 100, where At and Ac represent the absorbance in treated and control cultures, respectively. The drug concentration causing a 50% cell growth inhibition (IC50), is determined by interpolation from dose-response curves.
