Androgen receptor antagonist

The androgen receptor antagonist enzalutamide induces apoptosis, dysregulates the heat shock protein system, and diminishes the androgen receptor and estrogen receptor β1 expression in prostate cancer cells. Male sex hormones are also known as androgens; antiandrogens may also be called androgen receptor blockers. Some antiandrogens work by lowering the body's production of androgens while others block androgen receptors, limiting the body's ability to make use of the androgens produced. There are several different types of antiandrogens, including the following: Androgen receptor antagonists: Drugs that bind directly to and block the AR. These drugs include the steroidal Androgen synthesis inhibitors: Drugs that directly inhibit the enzymatic biosynthesis of androgens like We have previously identified a natural occurring, androgen receptor-specific antagonist. Atraric acid (AA) inhibits the transactivation of the androgen receptor (AR) and androgen-mediated growth of AR-expressing human prostate cancer (PCa) cell lines.

ORM-15341 functions as a full antagonist for all tested mutant ARs , with IC50 of 25, 51, 700, and 1160 nM for wtAR, AR(F876L), AR(T877A), and AR(W741L).

2021-03-19 · The introduction of second-generation androgen receptor antagonists (SG-ARAs) has greatly impacted the treatment of metastatic prostate cancer, providing tolerable and efficacious alternatives to Darolutamide is a novel androgen receptor (AR) antagonist with a distinct chemical structure compared to other AR antagonists and currently in clinical Phase 3 trials for prostate cancer. Androgens through their receptor stimulate masculinization of the fetus and induce male imprinting of the developing brain.
