Usage

Uses

Used in Pharmaceutical Industry:
4-(2-CYANOPROPAN-2-YLAMINO)-2-FLUORO-N-METHYLBENZAMIDE is used as a key intermediate in the synthesis of thiohydantoin androgen receptor antagonists. These antagonists are specifically designed for the treatment of castration-resistant prostate cancer, a condition where the cancer continues to grow despite low levels of testosterone.
Additionally, this compound is utilized in the preparation of imidazolidinedione compounds, which also act as androgen receptor antagonists. These antagonists are beneficial in the treatment of various diseases, including prostate cancer, by targeting the androgen receptor and inhibiting its activity, thus limiting the growth of cancer cells.

Effect of N-methyl deuteration on pharmacokinetics and pharmacodynamics of enzalutamide

Enzalutamide, a second-generation antiandrogen, has been developed for the treatment of castration-resistance prostate cancer. We synthesized the deuterated analogues 6 and found that it showed higher drug exposure and thus stronger antitumor potency in preclinical settings. Compound 6 is being developed clinically for the potential to be differentiated from enzalutamide through reduced dosages and a higher safety margin.
