Biochem/physiol Actions

β-ODAP is a potent inhibitor of HIF-prolyl hydroxylase-2 (PHD-2) that induces HIF dependent HRE (hypoxia response element) in normoxic conditions. β-ODAP is an analog of glutamic acid present in Lathyrus sativus (grass pea) that activates AMPA receptors. β-ODAP causes neurolathyrism upon prolonged consumption of L. sativus seeds.
β-ODAP is considered more neurotoxic than α-ODAP, thus during food processing, its conversion to α isomer is essential. β-ODAP exhibits its neurotoxicity via the activation of metabotropic glutamatergic receptor.

β-N-Oxalyl-L-α,β-diaminopropionic acid (l-ODAP) an α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor agonist activates protein kinase C in white leghorn chick brain. The current study focuses on the protein kinase C downstream signaling targets associated with L-ODAP excitotoxicity in SK-N-MC human neuroblastoma cells

Hypoxia inducible factor (HIF)-1α, a subunit of HIF transcription factor, regulates cellular response to hypoxia. In normoxic conditions, it is hydroxylated by prolyl hydroxylase (PHD)-2 and targeted for proteosomal degradation. Drugs which inhibit PHD-2 have implications in conditions arising from

Neurolathyrism is a motor neuron (MN) disease caused by β-N-oxalyl-L-α,β-diaminopropionic acid (L-β-ODAP), an AMPA receptor agonist. L-β-ODAP caused a prolonged rise of intracellular Ca(2+) ([Ca(2+)]i) in rat spinal cord MNs, and the [Ca(2+)]i accumulation was inversely proportional to the MN's
