Optical Activity UNSPECIFIED

TAK-448 is an investigational oligopeptide analog of kisspeptin and a potent agonist of the GPR54 receptor. In animals, acute TAK-448 administration stimulates luteinizing hormone (LH)/follicle-stimulating hormone release, whereas continuous subcutaneous exposure rapidly down-regulates the pituitary-gonadal axis, with rapid reduction of testosterone levels in a dose-dependent manner. TAK-448 has exhibited potent antitumor activity in rat androgen-dependent prostate cancer models. In accordance with the T reductions, TAK-448 treatment showed also more rapid reduction in plasma prostate-specific antigen(PSA) levels. TAK-448 had been in phase II clinical trials for the treatment of prostate cancer. However, this research has been discontinued.
