DL-O-Phosphoserine
Based on 1 Customer Validation
DL-O-Phosphoserine is a normal metabolite in human biofluids and is a mixture of phosphoserine with two stereochemical structures (D-type and L-type O-phospho-serine). O-phospho-L-serine is a competitive inhibitor of serine racemase and phagocytosis. O-phospho-L-serine inhibits the enzymatic reaction by competing with the active site of serine racemase, thereby affecting the production of D-serine. O-phospho-L-serine also mimics the phosphatidylserine head group, binds to the phosphatidylserine receptor, interferes with phagocytic signal transduction, and partially blocks the phagocytosis of apoptotic cells by cells. O-phospho-L-serin can be used in the research of retinal regeneration, bone repair, and insect growth and development.

Human Endogenous Metabolite |
O-phospho-L-serin shows inhibitory activity agasint serine racemase in a concentration-dependent manner, with the enzyme reaction inhibition rate of approximately 20% at 2 mM concentration[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In a miniature pig mandibular bone defect model experiment, a modified bone cement prepared by surgical implantation of a mixture of O-phospho-L-serin (Biozement D (2 g)-collagen-I (2.5%)-phosphoserine (50 mg)) was administered. Compared with the unmodified bone cement, the treated group had a higher absorption rate and bone regeneration rate, which effectively promoted bone healing[2].
In a silkworm growth and development experiment, O-phospho-L-serin (20 mM, 1 mL; added to feed; daily administration, from first to fifth instar larvae) delayed the development of silkworm larvae by about 6 days, significantly reduced the survival rate of larvae, and reduced the D-serine level in larvae until the cocooning stage compared with the control group[3].

Animal Model:Zebrafish retinal light damage model[1]
-
Dosage:0.65% saline containing either 20 mM O-phospho-L-serine (L-SOP), 0.5 μL
-
Administration:Intravitreally injection via Hamilton syringe; single dose
-
Result:Decreased the number of PCNA-positive Müller glia 51 hours after light damage.
Inhibited the regeneration of cone photoreceptors in the light-damaged retina.
There was no significant difference in the number of light-induced photoreceptor cell deaths between the O-phospho-L-serin-injected group and the control group 24 hours after light treatment.
