- Catalog Number
- Triptorelin Acetate
- Triptorelin is a synthetic gonadotropin-releasing hormone (GnRH) peptide agonist that binds to the GnRH receptor (GnRHR; Ki = 0.3 nM in CHO cells expressing the human receptor).1 It inhibits the growth of DU145, LNCaP, and PC3 prostate and OVCAR-3 ovarian cancer cells (IC50s = 62.1, 73.4, 98.1, and 67.7 μM, respectively).2 Triptorelin also inhibits the growth of the triple-negative breast cancer (TNBC) cell lines HCC1806 and MDA-MB-231 (EC50s = 58.29 and 31.59 μM, respectively).3 It stimulates follicle stimulating hormone (FSH) and luteinizing hormone (LH) release from primary rat pituitary cells when used at a concentration of 50 nM.2 It also decreases tumor volume of Dunning R3327H prostate tumor flank implants and reduces prostate and testis weight in rats when administered at a dose of 1 mg/kg per day.4 Formulations containing triptorelin have been used in the palliative treatment of advanced prostate cancer.
