Neuroprotective properties of the new derivative of glutamic and apovincaminic acids, ethyl -(3-alpha,16-alpha)-eburnamenin-14-carbopxylate of 2-aminopentadionic acid (LHT 1-02) were studied on a model of acute brain ischemia in cats. LHT 1-02 has proved to be more effective than the reference drugs vinpocetin and glycine in preventing the reperfusive damage, which was manifested by decreased postischemic hyperglycemia, activated utilization of oxygen in the brain, and suppressed postischemic metabolic lactate acidosis. Thus, the results of this comparative study show expediency of further investigations of LHT 1 - 02 as a potential neuroprotective drug.

The dysfunction of dopaminergic (DA) neurons is central to Parkinson's disease. Distinct synaptic vesicle (SV) populations, differing in neurotransmitter content (dopamine vs. glutamate), may vary due to differences in trafficking and exocytosis.

This study investigated the effects of a novel bombesin-related peptide (BR-b), derived from the skin of the Chaco tree frog (Boana raniceps), on glucose homeostasis in non-obese and hypothalamic-obese male rats. Hypothalamic obesity was induced in neonatal rats through high-dose administration of monosodium glutamate (MSG; 4 g/kg), while control animals (CTL) received an equimolar saline solution. At 70 days of age, both MSG and CTL groups underwent an oral glucose tolerance test (OGTT; 2 g/kg) with or without prior intraperitoneal administration of BR-b at doses of 0.

Prostate cancer (PCa) has emerged to be the second leading cause of cancer-related deaths in men. Molecular imaging of PCa using targeted radiopharmaceuticals specifically to PCa cells promises accurate staging of primary disease, detection of localized and metastasized tumours, and helps predict the progression of the disease. Glutamate urea heterodimers have been popularly used as high-affinity small molecules in the binding pockets of popular and well-characterized PCa biomarker, prostate specific membrane antigen (PSMA).

It is characterized by dysfunction in the U1 small nuclear ribonucleoproteins (snRNPs) complex, which may precede TAU aggregation, enhancing premature polyadenylation, spliceosome dysfunction, and causing cell cycle reentry and death. Thus, we evaluated the effects of a synthetic single-stranded cDNA, called APT20TTMG, in induced pluripotent stem cells (iPSC) derived neurons from healthy and AD donors and in the Senescence Accelerated Mouse-Prone 8 (SAMP8) model.
