Carba Ryl

چکیده
Carbaryl is a carbamate insecticide. Like all members of this chemical family, it inhibits the action of an enzyme that is an essential component of insect, fish, bird, and mammal nervous systems. The enzyme, acetyl cholinesterase (AChE), controls the chemical reaction that transforms acetylcholine into choline after acetylcholine has been used to transmit nerve impulses across the junctions between nerves. Without functioning AChE, acetylcholine accumulates and

Solid phase methodology was developed for the synthesis of carba-analogues of oxytocin. Two known compounds (deaminc-l-carba-oxytocin (I) and deamino-fi-carba-oxytocin (II) and two new analogues ((4-threonine]deamino-l-carba-oxytocin (III) and [4-threoninc}deamino-6-carba-oxytocin (IV» were synthesized using different approaches. The latter two compounds were found to possess high biological ac...

Chemoenzymatic syntheses of several NDP-carba-sugars have been successfully carried out, and these essential cofactor analogues are expected to be selective inhibitors of glycosyltransferase enzymes.
متن کاملComparison of the Carba NP, Modified Carba NP, and Updated Rosco Neo-Rapid Carb Kit Tests for Carbapenemase Detection.
The accurate detection of carbapenemase-producing organisms is a major challenge for clinical laboratories. The Carba NP test is highly accurate but inconvenient, as it requires frequent preparation of fresh imipenem solution. The current study was designed to compare the Carba NP test to two alternative tests for accuracy and convenience. These were a modified Carba NP test that utilized intra...
متن کاملWhy Carba-LNA-modified oligonucleotides show considerably improved 3'-exonuclease stability compared to that of the LNA modified or the native counterparts: A Michaelis-Menten kinetic analysis.
In this study, 12 different native or LNA, carba-LNA-modified dinucleoside phosphates were designed as simple chemical models to study how carba-LNA modifications improve the 3'-exonuclease (SVPDE in this study) resistance of internucleotidic phosphate compared to those exhibited by LNA-modified and the native counterparts. Michaelis-Menten kinetic studies for dimers 3 - 7, in which the LNA or ...
متن کاملEvaluation of the RAPIDEC® CARBA NP, the Rapid CARB Screen® and the Carba NP test for biochemical detection of carbapenemase-producing Enterobacteriaceae.
OBJECTIVES The objective of this study was the evaluation of the performance of two commercially available biochemical tests for the rapid detection of carbapenemase-producing Enterobacteriaceae compared with a home-made technique. METHODS A collection of 150 enterobacterial isolates, including 132 isolates with decreased susceptibility to at least one carbapenem molecule, were tested for car...
