L-AP3  (Synonyms: 3-Phosphono-L-alanine)

L-AP3, metabotropic glutamate receptor (mGluR) antagonist, inhibits D-phosphoserine and L-phosphoserine with IC₅₀s of 368 μM and 2087 μM, respectively^[1].

L-AP3 inhibits D-phosphoserine and L-phosphoserine with K_is of 151 μM and 845 μM, respectively^[1].
L-AP3 has agonistic activity in enhancing phospholipase D activity and decreasing CAMP formation in rat hippocampus^[1].
L-AP3 may have selectivity for Group II subtypes since it inhibits [³H]glutamate binding to mGlu3, receptors (K_i 125 μM)^[1].
L-AP3 is a potent inhibitor of sodium-dependent L-[³H]glutamate uptake in cerebellar and cortical synaptosomes (39 and 110 μM, respectively)^[1].
