Tetrahydroisoquinolines functionalized with carbamates as selective ligands of D2 dopamine receptor
(Springer, 2017-09)
A series of tetrahydroisoquinolines functionalized with carbamates is reported here as highly selective ligands on the dopamine D2 receptor. These compounds were selected by means of a molecular modeling study. The studies ...
Determination of carbamate insecticides in apples, pears, and lettuce by LC with UV detector
(Aoac International, 1997-11-01)
A simple and rapid method was developed for determination of 8 carbamate insecticides and 10 of their metabolites in apples, pears, and lettuce by liquid chromatography with UV diode array detector. With this method no ...

Direct synthesis of N-methylurethanes from primary amines with dimethyl carbonate
(Int Union Pure Applied Chemistry, 2005-10)
The mechanism of the reaction between amines with dimethyl carbonate (DMC)
has been investigated. Whereas in the absence of bases, they give methylation and carboxymethylation reactions without selectivity (BAl2 and BAc2 ...

(2016-01-01)
Sugarcane spirit is the second most consumed alcoholic beverage in Brazil and its consumption is increasing and attracting the interest of the foreign market, which demands high quality standards. This study evaluated the ...
A microbial consortium from a biomixture swiftly degrades high concentrations of carbofuran in fluidized-bed reactors
(2016)
An on-farm biopurification system (BPS) biomixture, with proven capacity to degrade carbofuran (CBF) was used as inoculum for a selective-enrichment process to obtain a bacterial consortium capable of using CBF as a sole ...
