| Abstract |
Dimethocaine (DMC, larocaine), a synthetic derivative of cocaine, is a widely distributed "legal high" consumed as a "new psychoactive substance" (NPS) without any safety testing, for example studies of metabolism. Therefore, the purpose of this work was to study its in-vivo and in-vitro metabolism by use of liquid chromatography-(high resolution) mass spectrometry (LC-HRMS(n)). DMC was administered to male Wistar rats (20 mg kg(-1)) and their urine was extracted either by solid-phase extraction after enzymatic cleavage of conjugates or by use of protein precipitation (PP). The metabolites were separated and identified by LC-HRMS(n). The main phase I reactions were ester hydrolysis, deethylation, hydroxylation of the aromatic system, and a combination of these. The main phase II reaction was N-acetylation of the p-aminobenzoic acid part of the unchanged parent compound and of several phase I metabolites. The metabolites identified were then used for identification of DMC in rat urine after application of a common user's dose. By use of GC-MS and LC-MS(n) standard urine-screening approaches (SUSAs), DMC and its metabolites could be detected in the urine samples. |

Attention Score in Context
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 December 2020.
All research outputs
#7,777,586
of 25,371,288 outputs
Outputs from Analytical & Bioanalytical Chemistry
#1,786
of 9,618 outputs
Outputs of similar age
#85,962
of 320,901 outputs
Outputs of similar age from Analytical & Bioanalytical Chemistry
#14
of 63 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. This one has received more attention than most of these and is in the 69th percentile.
So far Altmetric has tracked 9,618 research outputs from this source. They receive a mean Attention Score of 3.1. This one has done well, scoring higher than 80% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 320,901 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 72% of its contemporaries.
We're also able to compare this research output to 63 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 77% of its contemporaries.
