Background

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.

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
