Lonafarnib (Sch66336) is an orally active, blood-brain barrier penetrant farnesyltransferase (FPTase) inhibitor. Lonafarnib increases the phosphorylation levels of Akt, CaMKII and CREB, upregulates BDNF expression in the hippocampus, elevates the content of α7nAChR on cell membranes, and blocks the isoprenylation of H-Ras. Lonafarnib repairs synapses and reverses spatial memory deficits in Aβ1-42 model mice. Lonafarnib inhibits RSV fusion and replication, and alleviates virus-induced lung injury. Lonafarnib activates the lysosomal and autophagic pathways, and reduces the phosphorylation and aggregation of tau. Lonafarnib acts synergistically with Sorafenib (HY-10201) to promote apoptosis, and inhibits the proliferation and invasion of melanoma cells. Lonafarnib inhibits the farnesylation of progerin, repairs nuclear membrane defects, and activates the cGAS-STING-STAT1 signaling pathway. Lonafarnib can be used in research related to diseases including Alzheimer's disease, viral infections, melanoma, and progeria.

In Vitro

Lonafarnib (72 h) potently inhibits RSV A2 infection in HEp-2 cells (EC₅₀ = 57.7 nM, selectivity index > 168.2) and RSV B01 infection in HEp-2 cells (EC₅₀ = 75.5 nM, selectivity index > 168.2), while it also suppresses RSV A2 replication in human primary bronchial epithelial cells (EC₅₀ = 599.9 nM, selectivity index = 31.0) and RSV B01 replication in human primary bronchial epithelial cells (EC₅₀ = 515.0 nM, selectivity index = 36.1)^[2].
Lonafarnib inhibits RSV A2 infection in HEp-2 cells via a farnesyltransferase-independent mechanism^[2].
Lonafarnib (3.3 μM; pre (-2-0 h), during (0-2 h), and post (2-16 h) infection) blocks RSV A2 infection in HEp-2 cells primarily by inhibiting the viral entry process, with significant inhibitory effects observed during the 0-2 h entry window or over the full −2-22 h period^[2].
Lonafarnib inhibits RSV entry into HEp-2 cells and suppresses RSV F-induced intercellular fusion in HEK293T cells, confirming that it targets the RSV membrane fusion process^[2].
Lonafarnib binds to the pre-fusion RSV F trimer (K_D = 20.1 μM) and stabilizes its native conformation, while mutations M396A, S398A, D486A, F488L, and D489A in the RSV F protein abolish its fusion inhibitory effect^[2].
Lonafarnib (0.5-1.0 μM; 48 h) dose-dependently enhances macroautophagic flux in NIH3T3 mouse fibroblasts, primarily by accelerating autophagosome clearance via lysosomes; it also stimulates basal chaperone-mediated autophagy in NIH3T3 mouse fibroblasts^[3].
Lonafarnib (0.1-0.5 μM; 48 h) stimulates endosomal microautophagy in NIH3T3 mouse fibroblasts, promoting the transport of substrates to late endosomal compartments and their degradation^[3].
Lonafarnib (0.5-1.0 μM; up to 24 h) increases total proteolysis in NIH3T3 mouse fibroblasts in a dose-dependent manner, and this effect is completely mediated by the lysosomal pathway^[3].
Lonafarnib potently inhibits Rhes-mediated phosphorylated tau protein (PHF-1) accumulation in primary mouse hippocampal neurons, with an IC₅₀ of 61.00 nM^[3].
Lonafarnib (10 μM; 9 days) reduces the level of phosphorylated tau (Thr181) in wild-type and MAPT^R406W mutant human induced pluripotent stem cell-derived neurons^[3].
Lonafarnib (0.1-5 μM; 24 h) inhibits farnesyltransferase activity in BLM, MV3, MEWO and SKMel19 human metastatic melanoma cell lines^[4].
Lonafarnib (5 μM; 48-72 h) combined with 4 μM Sorafenib (HY-10201) synergistically suppresses the proliferation of BLM, MV3, MEWO and SKMel1 human metastatic melanoma cell lines, strengthens growth inhibition on primary melanoma cells derived from human skin metastases and reduces BLM cell viability^[4].
Lonafarnib (5 μM; 24 h) inhibits the mTOR pathway in human metastatic melanoma cells. When combined with Sorafenib, it significantly downregulates intracellular Bcl-2, completely eliminates Mcl-1, and only slightly alters Bcl-xL expression^[4].
Lonafarnib (3 μM; 14 days) reduces the invasion and proliferation of BL melanoma cells in organotypic skin models, and the combination with 2 μM Sorafenib completely blocks the invasion and proliferation of these cells^[4].
Lonafarnib (5 μM; 48 h) slightly increases the proportion of sub-G1 apoptotic cells in various melanoma cells, and its combination with Sorafenib greatly amplifies this pro-apoptotic effect without damaging human fibroblasts^[4].
Lonafarnib (5 μM; 24 h) combined with Sorafenib triggers typical apoptotic morphological features such as cell fragmentation in human metastatic melanoma BLM cells^[4].
Lonafarnib (5 μM; 12 h) combined with Sorafenib further elevates p8 mRNA in BLM, MV3, MEWO, SKMel19 human metastatic melanoma cell lines and increases CHOP mRNA in all detected melanoma cell lines^[4].
Lonafarnib (0.025 µM; 9 days) upregulates the proportion of p21-positive cells and phosphorylated STAT1 in normal and progeria fibroblasts, increases the formation of ring-shaped nuclei and micronuclei, elevates IFN-β mRNA levels, glycolysis and ATP content, downregulates the mRNA levels of multiple pro-inflammatory cytokines, reduces progerin levels and proteasome activity, and upregulates prelamin A levels and autophagic activity^[5].

In Vivo

Lonafarnib (10-80 mg/kg; i.p.; once daily; for 14 consecutive days) dose-dependently reverses Aβ_1-42-induced impairments in synaptic structure, function and spatial cognition in AD mice. Its mechanism of action involves upregulating hippocampal BDNF levels via the H-Ras-α7nAChR-dependent CaMKII-CREB pathway^[1].
Lonafarnib (17-34 mg/kg; p.o.; twice daily; for 4 consecutive days) dose-dependently reduces RSV replication levels in BALB/c mice, and improves body weight and pulmonary pathological conditions of mice when administered via early intervention or post-infection oral delivery^[2].
Lonafarnib (80 mg/kg per day; p.o.; intermittent administration/acute administration) reduces tau protein inclusions, brain atrophy, glial reactivity and behavioral deficits in rTg4510 mice, whereas acute administration has no effect on established tau protein pathology^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

C57BL/6J (male, 2 months old, intracerebroventricular injection of soluble Aβ_1-42 to induce pathology)^[1]
Dosage:

10 mg/kg; 30 mg/kg; 50 mg/kg; 80 mg/kg
Administration:

i.p.; daily; 14 days
Result:

Reduced MWM escape latency and prolonged target quadrant residence time, thereby improved spatial learning and memory in Aβ1-42 mice at 50 mg/kg and 80 mg/kg.
Rescued impaired hippocampal synaptic electrophysiology including EPSP slopes, paired-pulse ratios, PTP and L-LTP at 50 mg/kg. It also restored damaged dendritic architecture, elevated synaptic PSD-95 and synaptophysin levels, upregulated surface α7nAChR expression, activated Akt/CaMKII/CREB phosphorylation, and increased mature hippocampal BDNF content.
Demonstrated that the BDNF upregulation relied on α7nAChR and CaMKII signaling rather than ERK or PI3K pathways. H-Ras overexpression reversed the elevations of surface α7nAChR and BDNF, while TrkB/Fc chimera completely abolished all synaptic and cognitive improvements.

Result:

Improved body weight from day 1 post-infection at 34 mg/kg early intervention, while post-infection treatment only slightly recovered weight at day 4.
Reduced lung viral titers dose-dependently: early 17/34 mg/kg downregulated titers 3.8/7.4-fold; post-infection 17/34 mg/kg downregulated titers 3.7/4.1-fold.
Attenuated RSV-mediated lung inflammation in all early-intervention groups and relieved lung injury at 34 mg/kg post-infection, with quantitative pathology confirming alleviated alveolitis and lesions in early groups.

Animal Model:

rTg4510 (tauopathy transgenic, 10 weeks old at initiation, evaluated at 20 weeks old); wild-type littermate controls^[3]
Dosage:

80 mg/kg
Administration:

Lowered cortical/hippocampal MC1-tau inclusions and cortical/hippocampal PHF-1 phosphorylated tau; cut cortical/hippocampal Rhes-positive cell density.
Enlarged coronal brain area, mitigated hippocampal microgliosis and cortical astrogliosis.
Rescued nest-building impairment and suppressed circling behavior.
Decreased sumoylation- and ubiquitination-positive cells, changed co-labeling likelihood of MC1-tau with SUMO/ubiquitin.
Lessened pathological tau in cortical lysates without altering total tau, and erased insoluble high-molecular-weight tau aggregates.

Stock Solution Working Solution

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
