    TLDR Scientists made the first metal-based compounds from a nonsteroidal antiandrogen drug, which showed potential in fighting both hormone-dependent and independent prostate cancer cells.
    In 2008, researchers synthesized the first organometallic complexes derived from the nonsteroidal antiandrogen nilutamide, with a ferrocenyl substituent. The N-substituted complexes had a weak or moderate antiproliferative effect (IC50 around 68 μM) on hormone-dependent and -independent prostate cancer cells. However, the C(5)-substituted compounds showed toxicity levels 10 times higher (IC50 around 5.4 µM), likely due to a structural effect linked to the aromatic character of the ferrocene. This effect seemed connected to a cytotoxic effect rather than an antihormonal one. The study suggested a new family of molecules that could be active against both hormone-dependent and hormone-independent prostate cancer cells.

      community RU-58841 Lung Disease Possibility | Chest pain, "heart issues", etc

      in Treatment  21 upvotes 9 months ago
      Some users of RU-58841 report cardiovascular symptoms like heart palpitations and chest tightness, which may be linked to its metabolites causing lung disease. The safety of RU-58841 is uncertain due to lack of long-term data and concerns about product purity, especially from gray market sources.

      The conversation discusses the use of RU58841, a non-FDA approved research chemical for hair loss, with mixed opinions on its safety and effectiveness. Some users are willing to try it as a last resort after other treatments like Minoxidil and Finasteride failed, while others express concerns about potential long-term side effects and lack of official research.

      community For those on TRT and suffer from a more aggressive type of (AGA) hairloss, what are your hair safe protocols?

      in Chat  6 upvotes 1 year ago
      People on testosterone replacement therapy (TRT) with aggressive androgenetic alopecia (AGA) discuss using Dutasteride or Finasteride, sometimes combined with topical treatments like RU58841 or CB-03-01 (Breezula), to prevent hair loss. Concerns about side effects and costs of certain treatments are mentioned, with one individual sharing their experience of slowed hair loss using Finasteride alone.

      The conversation discusses hair loss treatments, specifically Minoxidil, finasteride, and RU58841. Concerns are raised about the lack of studies on RU58841 and its potential effects.

      community Update: Chest discomfort from RU58841

      in Update  35 upvotes 10 months ago
      A user experienced severe chest pains and shortness of breath after using RU58841 for hair loss and was advised by a doctor that blocking androgens can weaken the heart. They decided to continue with finasteride, minoxidil, and a hair transplant instead.
