The most obvious, first effects (gingival and hair problems) of absence of ascorbic acid in humans come from the resulting defect in hydroxylation of proline residues of collagen, with reduced stability of the collagen molecule, causing scurvy. Increased serum and urine levels of hydroxyproline have also been demonstrated in Paget's disease. [10]

S)-3,5-Dihydroxyphenylglycine or DHPG is a potent agonist of group I metabotropic glutamate receptors (mGluRs) mGluR1 and mGluR5. DHPG was the first agonist shown to be selective for group I mGluRs. [1] Agonist activity is found in only the (S)-isomer, and (S)-DHPG may be a partial agonist of group I mGluRs. [1]
The first compound studied was glycine which was hypothesized by Daniel Javitt after observation that people with phencyclidine(PCP)-induced psychosis were lacking in glutamate transmission. [1] (PCP is an NMDA receptor antagonist that blocks glutamate.) In giving glycine to people with PCP-induced psychosis a recovery rate was noted.
Glutamatergic means "related to glutamate". A glutamatergic agent (or drug ) is a chemical that directly modulates the excitatory amino acid ( glutamate / aspartate ) system in the body or brain. Examples include excitatory amino acid receptor agonists , excitatory amino acid receptor antagonists , and excitatory amino acid reuptake inhibitors .
Other drugs like codeine and tamoxifen, which require CYP2D6-mediated activation into their respective active metabolites, may have their therapeutic effects attenuated. [16] Likewise, CYP2D6 inhibitors such as paroxetine or fluoxetine can reduce chlorpromazine clearance, increasing serum levels of chlorpromazine and potentially its adverse ...
Vermont, a state with a long waiting list for medically based drug treatment, suspended a doctor’s license over incomplete paperwork. As doctors face scrutiny from the DEA, states have imposed even greater regulations severely limiting access to the medications, according to a 2014 report commissioned by the federal agency SAMHSA.
The amino acid L-glutamate is the major excitatory neurotransmitter in the central nervous system and activates both ionotropic and metabotropic glutamate receptors. Glutamatergic neurotransmission is involved in most aspects of normal brain function and can be perturbed in many neuropathologic conditions.
