What are carbamate drugs?
Carbamate anticonvulsant agents are newer antiepileptic drugs whose exact mechanism of action is uncertain. It has some inhibitory effect at the N-methyl-D-aspartate (NMDA) receptors and slightly potentiates gamma-aminobutyric acid (GABA) activity.
Are carbamates natural?
Natural occurrence Within nature carbon dioxide can bind with neutral amine groups to form a carbamate, this post-translational modification is known as carbamylation. This modification is known to occur on several important proteins; see examples below.
What are organic carbamates?
Organic carbamates (or urethanes) are structural elements of many approved therapeutic agents. Structurally, the carbamate functionality is related to amide-ester hybrid features and, in general, displays very good chemical and proteolytic stabilities.
Are carbamates harmful?
The outcomes for carbamate toxicity depend on the amount ingested. For mild cases, full recovery is expected, but severe cases can lead to prolonged hospitalization with the need for ventilation.
Are carbamates harmful to humans?
Carbamate exposure can cause headaches, dizziness or weakness. It can make you feel like you will throw up. It can also cause shaking, stomach cramps, diarrhea and sweating. Skin exposure to carbamates causes a minor rash.
How toxic are carbamates?
The most common cause of mortality in OPC and carbamate poisoning is respiratory failure; however, death is rare, occurring in 0.04-1% of typical pesticide poisonings. In severe poisoning, death usually occurs within the first 24 hours if it is untreated.
Are carbamates neurotoxins?
Induction of oxidative stress by some carbamates might also cause developmental neurotoxicity. It should also be noted that the carbamate physostigmine inhibits DNA synthesis in undifferentiated neuronotypic PC12 cells (a standard in vitro model for neuronal development).
Are carbamates carcinogenic?
An increased incidence of lung tumors has been observed in rodents exposed to ethyl carbamate by oral or inhalation exposure. The International Agency for Research on Cancer (IARC) has classifed ethyl carbamate as a Group 2B, possibly carcinogenic to humans.
