IC50: 1,260 μM for the metabotropic glutamate receptor mGluR4

O-Phospho-D-Serine is a weak agonist of the metabotropic glutamate receptor mGluR4.

mGluR4 receptors, a member of the G protein-linked family of receptors for glutamate, are negatively coupled to cAMP. Its expression is highest in granule cells of the cerebellum that send parallel fibers that synapse with Purkinje cell dendrites.

In vitro: The affinity of L-serine-O-phosphate was examined in a baby hamster kidney cells expressing subtype mGluR1 or mGluR4 of the mGluR family. Results showed that both L-serine-O-phosphate or O-Phospho-D-Serine at 3 mM did not inhibit PI-hydrolysis as stimulated by 10 μM glutamate in BHK cells expressing mGluR1. However, L-serine-O-phosphate was a potent agonist at the mGluR4 subtype, which was negatively coupled to adenylate cyclase, while O-Phospho-D-Serine was found to be weakly active [1]. In another study, to test whether phosphatidylserine was recognized by amebae, calcium-treated cells were incubated with annexin V prior to adherence to or ingestion by E. histolytica. It was found that the coreceptor could be inhibited by phospho-l-serine and to a lesser extent by O-Phospho-D-Serine but not by phospho-l-threonine, which was consistent with the coreceptor functioning in the adherence and ingestion of erythrocytes via recognition of phosphatidylserine [2].

In vivo: Up to now, there is no animal in vivo data reported.

Clinical trial: So far, no clinical study has been conducted.
