Duality nature of Selective Androgen Receptor Modulators and Specific Steroids Substance

Selective Androgen Receptor Modulators (SARMs) are the novel class of the androgen receptors (AR), often called tissue-selective AR ligands. Discovery of SARMs will give a possibility to the alternative therapy for androgens therapy (osteoporosis, prostate cancer, muscle wasting). SARMs should have high specificity for the AR, tissue-selective pharmacokinetic activities, improved oral bioavailability and pharmacokinetic profile which allows once-a-day administration [1].

Example of SARMs is flutamide (flutamidum, Eulexin, imid 2-methyl-N-{4-nitro-(3-trifluoromethyl)-phenyl]- propionic acid), a synthetic nonsteroidal drug that is a competitive antagonist of the androgen receptor. SARMs were recognized as forbidden substances by the World Anti-Doping Agency (WADA) and since 2004 they are on the Prohibited List. To point on the Prohibited List 2019 “Substance and methods prohibited at all time (in- and out-of-competition)” SARMs belong to group S1. 2. Other Anabolic Agents, and to group S4. Hormone Antagonist and Modulators [2].

The main role of an anti-doping laboratory is to analyse and to determine whether a given substance should be prohibited in sport. The principal analyses of SARMs and Specific Steroid Substance are a different variant of chromatography (LC — liquid or GC — gas) with many detection techniques (MS — mainly mass spectrometer, MS/MS — tandem mass spectrometer).
