RSV Inhibitor

(Rac)-Lonafarnib (Sch66336 racemate) is an isomer of Lonafarnib (HY-15136). 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.
