Chromatography of carbamates

Chromatographic Reviews, 1967
Abstract We have attempted to stress the major areas of chromatographic techniques for carbamate analyses and also to illustrate the influence of carbamate moiety substituents on chromatographic behavior. The remarkable versatility of chromatographic techniques, as demonstrated by their many applications to complex analyses, is apparent from the ...

A method for the determination of methyl carbamate and ethyl carbamate in wines

Food Additives and Contaminants, 1992
A method is described for the simultaneous determination of methyl carbamate (MC) and ethyl carbamate (EC) in wines that is based on: (a) extraction of the sample with dichloromethane using an extraction tube or an alumina-Celite column, (b) concentration of the extract to a small volume, and (c) determination by gas-liquid chromatography-thermal ...

POISONING BY CARBAMATE PESTICIDES

Medical Journal of Australia, 1977
In recent years the number of carbamate pesticides registered for use in New South Wales has increased. Some of the newer carbamates are very toxic and have cholinergic properties similar to those of the organic phosphates, though the effect is of much shorter duration.

The basis of the carbamate reaction

Archives of Biochemistry and Biophysics, 1955
Abstract Previously, it had been assumed that the carbamination of amino acids could be carried out only in strongly alkaline media (in the presence of alkaline-earth hydroxides). The carbamino carboxylic acids, however, are also formed at neutral and mildly acid reactions.

Organophosphate and Carbamate Poisoning

Emergency Medicine Clinics of North America, 2015
Organophosphates (OPs) and carbamates have a wide variety of applications, most commonly as pesticides used to eradicate agricultural pests or control populations of disease-carrying vectors. Some OP and carbamates have therapeutic indications such as physostigmine.

Mechanisms of lung tumorigenesis by ethyl carbamate and vinyl carbamate

Drug Metabolism Reviews, 2010
Vinyl carbamate (VC) and ethyl carbamate (EC) induce the formation of lung tumors. The mechanism involves a two-step oxidation of EC to VC and VC to an epoxide, both of which are mediated mainly by CYP2E1. Interaction of the epoxide with DNA leads to the formation of DNA adducts, including 1,N(6)ethenodeoxyadenosine and 1,N(4)-ethenodeoxycytidine.

The Pharmacology of Propanediol Carbamates

1971
Publisher Summary This chapter discusses the pharmacology of propanediol carbarnates. The intensive interest generated in the pharmacology of meprobamate represented a departure from previous emphasis on more complex and more sophisticated chemical substances as potential therapeutic agents.
