    TLDR Afatinib, neratinib, and zanubrutinib could be effective against KRASG12C-mutant tumors.
    This study aimed to repurpose FDA-approved drugs to inhibit the KRASG12C mutation in non-small-cell lung cancer using machine learning, molecular docking, and molecular dynamics. The XGBoost algorithm predicted inhibitors with 0.85 validation accuracy from 67 drugs, identifying afatinib, dacomitinib, acalabrutinib, neratinib, zanubrutinib, dutasteride, and finasteride as potential candidates. Afatinib, neratinib, and zanubrutinib showed stable covalent binding at the KRASG12C active site, similar to existing inhibitors. The study concludes that these drugs, especially afatinib, could be effective against KRASG12C-mutant tumors, warranting further investigation.

      The user has been using topical finasteride 0.1% for almost 7 months but is experiencing worsening hair loss and is considering adding minoxidil 5% to their regimen. They are hesitant about oral finasteride and are exploring options for topical treatments, including minoxidil and possibly dutasteride.

      Hair loss treatments, specifically the use of finasteride, microneedling and potentially oral minoxidil. People discussed their experiences with finasteride, its effects on sexual behaviors, as well as potential solutions such as tadalafil or using other growth factor signal peptides for hope in curing male pattern baldness.

      The conversation is about someone who has been taking finasteride for hair loss without success, considering switching to dutasteride or giving up treatment. Suggestions include trying dutasteride, microneedling, infrared therapy, multivitamins, and high-concentration topical solutions combining finasteride and dutasteride.

      Dutasteride is likely the most effective treatment for male pattern baldness, followed by finasteride and minoxidil in various forms and dosages. Users discuss personal experiences, dosages, and potential side effects, with some considering combining treatments for better results.
