生物活性

L-803087 TFA is a potent and selective somatostatin sst4 receptor agonist with a Ki of 0.7 nM. L-803087 TFA is >280-fold more selective for sst4 receptor than other somatostatin receptors. L-803087 TFA facilitates AMPA-mediated hippocampal synaptic responses in vitro and increases kainate-induced seizures in mice[1][2].

IC50 & Target

Ki: 0.7 nM (sst4 receptor), 199 nM (sst1 receptor), 4720 nM (sst2 receptor), 1280 nM (sst3 receptor) and 3880 nM (sst5 receptor)[1]

体外研究
(In Vitro)

L-803087 has Ki values for cloned human sst1, sst2, sst3 and sst5 receptors of 199, 4720, 1280 and 3880 nM, respectively[1].
L-803087 has a diamine moiety that maps to lysine on the phmacophore, but relation of this molecule to the aromatic and the Trp substituents of the phmacophore are not obvious. L-803087 does not inhibit secretion of growth hormone, insulin, or glucagon[1].

体内研究
(In Vivo)

L-803087 (5 nmol) is doubled seizure activity in wild-type mice on average. Interestingly, this effect is blocked by 3 nmol Octreotide. In hippocampal slices from wild-type mice, Octreotide (2 μM) does not modify AMPA-mediated synaptic responses while facilitation occurred with L-803087 (2 μM)[2].
