Farnesyltransferase inhibitor LNK-754 could rapidly cross the blood-brain-barrier after a single oral dose. Pharmacokinetic analysis was performed by Medicilon

Age-related neurodegenerative disorders are characterized by the progressive accumulation of misfolded and aggregated proteins. SNARE protein ykt6 plays a crucial role in proteostasis and lysosomal function by enhancing hydrolase trafficking under stressful conditions. Activating ykt6 by small-molecule farnesyltransferase inhibitors (FTIs) restores lysosomal activity and reduces a-synuclein in patient-derived neurons and mice. Pharmacokinetic studies revealed that after a single oral dose, the FTI (LNK-754) was cleared from plasma within 20 hours and could rapidly cross the blood-brain-barrier. Pharmacokinetic analysis was performed as a service provided by Medicilon.
