Advanced Analytical Methods Crucial for Detecting New Doping Drugs

The landscape of sports doping is constantly evolving, with athletes and their support networks increasingly using emerging therapeutics and non-approved drugs to gain an unfair advantage. These substances often lack established detection methods, posing a significant challenge to anti-doping efforts. This review addresses the critical need for robust analytical strategies to identify novel performance-enhancing substances in human doping controls.

The review highlighted that high-resolution mass spectrometry (HRMS), particularly LC-HRMS, offers unparalleled capabilities for the non-targeted screening and identification of unknown or emerging doping agents due to its superior sensitivity and specificity. It was noted that while targeted methods are effective for known substances, they are inherently limited in detecting novel compounds. The authors emphasized the significant challenge posed by the rapid structural modification of existing drugs and the emergence of designer substances, requiring continuous method development. The most critical finding was the identification of liquid chromatography-high resolution mass spectrometry (LC-HRMS) as the gold standard for comprehensive, non-targeted screening, capable of detecting a broad spectrum of substances even at low nanogram per milliliter concentrations. Furthermore, the review underscored the ongoing "arms race" between dopers and anti-doping agencies, where the development cycle for new detection methods often lags behind the introduction of new illicit substances, creating a detection window for cheaters.
