l 803087

L-803087 is a potent and selective agonist of the growth inhibitor sst4 receptor with a Ki value of 0.7 nM for sst4, demonstrating over 280-fold selectivity compared to other growth inhibitory receptors. L-803087 induces AMPA-mediated synaptic responses in the hippocampus in vitro and increases seizures in alginate-induced seizure-busting mice in vivo.

L-803087 TFA is a highly potent and selective agonist of the somatostatin sst4 receptor, exhibiting a Ki value of 0.7 nM. It displays a remarkable selectivity, being over 280-fold more preferential for the sst4 receptor compared to other somatostatin receptors. Furthermore, L-803087 TFA promotes AMPA-mediated synaptic responses in hippocampal preparations and enhances kainate-induced seizures in mice.
