Excitatory amino acids and their receptors play an important role in both normal synaptic transmission and excitotoxic-mediated neuronal death. In the present investigation we have prepared a series of glutamate analogs and examined the pharmacological specificity with which they interact with excitatory amino acid receptors. Included within this group of compounds is a potent excitotoxic amino...
Lathyrus sativus L. (Grass pea) is the source for cheap and nutritious food choice in drought and famine susceptible zones in greater part of North India and Africa. The non-protein amino acid β-N-oxalyl-L-α,β-diaminopropionic acid (β-ODAP) has been known for decades for its potent neurotoxic effect, causing irreversible neurodegenerative disease "neurolathyrism", present in both seed and leaf ...
beta-N-oxalyl-amino-L-alanine, (L-BOAA), an excitatory amino acid, acts as an agonist of the AMPA subtype of glutamate receptors. It inhibits mitochondrial complex I in motor cortex and lumbosacral cord of male mice through oxidation of critical thiol groups, and glutaredoxin, a thiol disulfide oxido-reductase, helps maintain integrity of complex I. Since incidence of neurolathyrism is less com...
Introduction The Lathyrus/lathyrism challenge is broad-based by its nature and requires multi-disciplinary efforts of specialists in the field of epidemiology, neurology, biochemistry, chemistry, nutrition, and agronomy. The role of chemists is in systematic determination of minor natural products in L. sativus seeds so that the sole responsibility of ß-ODAP for neurolathyrism is ascertained . ...
Introduction To meet the protein requirement of the ever growing and predominantly vegetarian human population in India, efforts are in progress in the country to increase pulse production and to make those pulses consumable, which may otherwise adversely affect human health. Pulses constitute a primary source of proteins, add flavour and variety to a well-planned course of meals. These pulses ...
Human ingestion of "chickling peas" from the plant Lathyrus sativus, which contains an excitatory amino acid, L-BOAA (L-beta-N-oxalylamino-L-alanine), leads to a progressive corticospinal neurodegenerative disorder, neurolathyrism. Exposure to L-BOAA, but not its optical enantiomer D-BOAA, causes mitochondrial dysfunction as evidenced by loss of complex I activity in vitro in male mouse brain s...
Toxic components of natural foodstuffs are discussed, with special reference to lathyrogens, pressor amines, azoxyglycosides, and labile sulfur compounds. The osteolathyrogen, gamma-glutamyl-beta-aminopropionitrile, in sweet pea (Lathyrus odoratus) seeds induces skeletal deformities and aortic rupture, probably by interfering with normal maturation of collagen fibres. Neurolathyrism in man may ...
Lathyrus sativus is a grain legume high in protein (25-30%) that can be grown under limited moisture conditions. However, the Government of India has imposed a ban on its sale because of the association with human neurolathyrism in the population subsisting on it. Over the years, by mutation and conventional breeding, attempts were made to reduce the amount of oxalyl diamino propionic acid (ODA...
Neurological effects have for centuries been observed to accompany in many instances the consumption of excessive amounts of lathyrus meal as food, particularly in parts of India and in the Mediterranean area in times of food scarcity. This condition, which is known as spontaneous clinical neurolathyrism, occurs chiefly in the male and is characterized principally by reflex irritability, weakne...
