    TLDR Researchers developed reliable models to predict how well certain compounds bind to androgen receptors, emphasizing the importance of atomic electronegativity.
    In 2019, researchers analyzed 109 hydantoin-based androgen receptor modulators to develop a predictive model for their binding affinities. They created two QSAR models using genetic algorithm descriptor selection, with Model-I and Model-II including 8 and 7 descriptors, respectively. Both models were validated internally and externally, with Model-I achieving an R² of 0.858 and Model-II an R² of 0.833 for their respective training sets. The models' robustness was confirmed through Y-scrambling and Leave-Many-Out procedures, and their applicability was assessed with leverage analysis. Docking analysis supported the QSAR findings, particularly highlighting the role of atomic electronegativity in influencing androgen receptor binding. The study concluded that the QSAR models are reliable and can predict the binding abilities of unknown compounds, suggesting that future design and optimization of AR modulators should consider atomic electronegativities to enhance binding affinity.

      community Alternatives/unorthodox hairloss protocols to the big three

      in Chat  1 upvotes 2 weeks ago
      The conversation discusses alternative and unorthodox hair loss treatments, including RU58841, nandrolone, and dianabol, as well as theoretical approaches involving high doses of estrogen and selective estrogen receptor modulators. These methods are considered extreme and potentially harmful but are explored for those unable to tolerate traditional 5-alpha reductase inhibitors.

      A user humorously suggests an extreme hair loss treatment regimen involving multiple medications and therapies, including Dutasteride, Minoxidil, RU58841, and others, claiming it would prevent hair loss but with potential side effects like gynecomastia. The conversation highlights concerns about safety, side effects, and the effectiveness of such a comprehensive approach.
