PROTACs in cancer therapy: targeted degradation of GPX4, PARP and epigenetic regulators

The efficacy of degrading the androgen receptor through dermal application in DP cells, a delivery system for topical drugs that involves dissolving microneedles, and rosemary oil as an alternative anti-androgen.

The conversation discusses the approval of Kintor Pharmaceutical's AR-PROTAC (GT20029) for clinical trials in China for acne and androgenic alopecia. One user expresses optimism about new treatments being developed and seeks clarification on how the new drug works, specifically if it temporarily degrades the AR protein to reduce DHT sensitivity in hair follicles.

The conversation discusses positive initial trial results for GT20029, a topical compound for hair loss that degrades androgen receptors, potentially requiring only weekly application. Participants express hope for this treatment to be more effective and convenient than current options like Minoxidil, Finasteride, and RU58841.

Kintor Pharma finished enrolling and dosing participants in a Phase I trial for a hair loss treatment called AR-PROTAC (GT20029). The effectiveness of another drug, pyrilutamide (KX-826), for hair loss will be clearer after a Phase 2 trial expected to complete in January 2023.

The conversation discusses GT20029, a compound by Kintor Pharma that degrades androgen receptors and is in trials, with potential as a hair loss cure. Another promising treatment mentioned is an antibody that blocks prolactin and has shown positive results in macaques.

The conversation discusses concerns that Anagenic's version of GT20029 might not be as effective or safe as Kintor's, with comparisons to issues faced by pyrilutamide. The chemical structure of the drug has been published.
