Works as described, very interesting compound..
By Jonathan Fay on 05/30/2019
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: COSH-1

Allosteric modulation of radioactive Agonist (CP) and Antagonist (SR) binding by various concentrations of Org 27569 and inhibition of agonist stimulated GTPgS binding.

For a constitutively inactive mutant tested, Org 27569 had enhanced potency and appeared to slow radio-labeled agonist dissociation so much that equilibrium was not achieved during the typical 1 hour incubation, at higher Org concentrations.
