GLPG0492 R enantiomer is primarily investigated for its potential therapeutic applications in the treatment of muscle-related disorders. It is known to act as a selective androgen receptor modulator (SARM), which makes it a promising candidate for addressing conditions like muscle wasting, sarcopenia, and cachexia. By selectively targeting androgen receptors in muscle and bone tissues, it aims to promote muscle growth and strength without the adverse effects typically associated with traditional anabolic steroids. Additionally, its R enantiomer form is specifically studied for enhanced efficacy and reduced off-target effects, making it a focus in preclinical and clinical research for improving muscle health and quality of life in patients with chronic illnesses or age-related muscle decline.
