Biological Activity

PSEM 89S is a PSAM^L141F-GlyR and PSAM^L141F,Y115F-5-HT₃ chimeric ion channel agonist (EC₅₀ values are 3.4 and 2.2 μM, respectively). Activates cortical neurons expressing PSAM^L141F,Y115F-5-HT₃ chimeric ion channels and inhibits activity of neurons expressing PSAM^L141F-GlyR in vitro. Silences hypothalamic AGRP neurons transfected with PSAM^L141F-GlyR chimeric ion channels in mice in vivo, leading to suppression of feeding. Brain penetrant.

Plasmid vectors for the transfection of cells with PSAM^L141F-GlyR and PSAM^L141F,Y115F-5-HT₃ are available from Addgene.
