Abstract

Myo-inositol trispyrophosphate (ITPP) is a novel allosteric effector of haemoglobin with high permeation selectivity across the red blood cell plasma membrane. Due to its potential to reduce the oxygen affinity of haemoglobin, ITPP application results in an enhanced oxygen release in hypoxic tissues. Therefore, ITPP is being examined for the treatment of numerous illnesses that involve hypoxia, such as cardiovascular diseases, cancer or Alzheimer's disease. Similar to the prohibited substance Efaproxiral®, ITPP increases maximal exercise capacity in mice, providing high potential to be misused in sports. To keep up with cheating athletes, a fast and reliable liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for screening and confirmation of ITPP in human urine for doping control purposes was developed. According to the molecule's distinct hydrophilic properties, extraction from complex biological matrices is challenging and conventional reversed phase liquid chromatography (RPLC) separations are not suitable for its detection. Therefore an approach based on hydrophilic interaction liquid chromatography (HILIC) Orbitrap mass spectrometry was established. The methodology was fully validated for qualitative purposes. Screening and confirmation assay are characterized by satisfactory specificity and robustness, adequate intra-day (screening: 4.9-8.1%; confirmation: 2.0-6.7%) and inter-day precision (screening: 4.6-9.1%; confirmation: 1.8-6.6%), excellent linear correlations (>0.99) with sufficient LLOD in the sub ng/mL range (screening: 15 ng/mL; confirmation: 1 ng/mL). In addition it could be shown that ITPP is stable in human urine under the mandatory storage period and conditions for doping control laboratories. To our knowledge, this is the first validated 'dilute-and-inject' LC-MS/MS method for the reliable detection of ITPP in human urine. Copyright © 2014 John Wiley & Sons, Ltd.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 5. 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 21 December 2017.
All research outputs
#6,758,897
of 24,701,898 outputs
Outputs from Drug Testing and Analysis
#393
of 1,445 outputs
Outputs of similar age
#59,371
of 233,955 outputs
Outputs of similar age from Drug Testing and Analysis
#7
of 21 outputs
Altmetric has tracked 24,701,898 research outputs across all sources so far. This one has received more attention than most of these and is in the 72nd percentile.
So far Altmetric has tracked 1,445 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.0. This one has gotten more attention than average, scoring higher than 72% 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 233,955 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 74% of its contemporaries.
We're also able to compare this research output to 21 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 66% of its contemporaries.
