Biological Activity
| ln Vitro | Degarelix exhibits only very weak histamine-releasing properties and has the lowest histamine-releasing capacity among LHRH antagonists, including Cetrorelix, Abarelix, and Ganirelix [1]. Degarelix (1 nM-10 μM, 0-72 hours) reduces cell viability in all prostate cell lines (WPE1-NA22, WPMY-1, BPH-1, VCaP cells), except PC-3 cells [2] . Degarelix (10 μM, 0-72 hours) exerts a direct effect on prostate cell growth through apoptosis [2]. Cell viability assay[2] Cell lines: WPMY-1, WPE1-NA22, BPH-1, LNCaP and VCaP Concentration: 1 nM-10 μM Incubation time: 48 hours and 72 hours for WPMY-1 cells, 72 hours for WPE1-NA22 cells , BPH-1 cells (48 hours and 72 hours), LNCaP cells (48 hours and 72 hours) Results: Cell viability was reduced in all prostate cell lines except PC-3 cells. Apoptosis analysis[2] Cell lines: WPE1-NA22, BPH-1, LNCaP and VCaP Concentration: 10 μM Incubation time: 24, 48 and 72 hours Results: Induced significant increase in caspase 3/7 activation. |
| ln Vivo | Degarelix (0-10 μg/kg; subcutaneous injection; once) reduces plasma LH levels and plasma testosterone levels in castrated rats in a dose-dependent manner [3]. Degarelix is stable when incubated in microsomes and cryopreserved hepatocytes from animal liver tissue. In rats and dogs, the majority of the degarelix dose is eliminated via urine and feces in equal amounts (40-50% in each matrix) within 48 hours, whereas in monkeys the main route of excretion is feces (50 %) and kidney (22%)[4]. Animal model: Male Sprague-Dawley rat, castrated [3] Dosage: 0.3, 1, 3 and 10 μg/kg or 12.5, 50 and 200 μg/kg Administration: subcutaneous injection, once Result: Dose-dependent And the minimum reversible effective dose is 3 μg/kg to reduce plasma LH levels. For the 50 μg/kg and 200 μg/kg doses, absorption t1/2 values were 4 minutes and 30 minutes, Tmax values were 1 hour and 5 hours, and apparent plasma disappearance t1/2 values were 12 hours and 67 hours, respectively. The minimum effective dose is 1 μg/kg, and plasma testosterone levels decrease in a dose-dependent manner. |

| Additional Infomation |
Degarelix Acetate is the acetate form of a long-acting, synthetic peptide with gonadotrophin-releasing hormone (GnRH) antagonistic properties. Degarelix targets and blocks GnRH receptors located on the surfaces of gonadotroph cells in the anterior pituitary, thereby reducing secretion of luteinizing hormone (LH) by pituitary gonadotroph cells and so decreasing testosterone production by interstitial (Leydig) cells in the testes. See also: Degarelix (has active moiety). Drug Indication Degarelix Accord is a gonadotrophin releasing hormone (GnRH) antagonist indicated: for treatment of adult male patients with advanced hormone-dependent prostate cancer . for treatment of high-risk localised and locally advanced hormone dependent prostate cancer in combination with radiotherapy. as neo-adjuvant treatment prior to radiotherapy in patients with high-risk localised or locally advanced hormone dependent prostate cancer . FIRMAGON is a gonadotrophin releasing hormone (GnRH) antagonist indicated: - for treatment of adult male patients with advanced hormone-dependent prostate cancer . - for treatment of high-risk localised and locally advanced hormone dependent prostate cancer in combination with radiotherapy. - as neo-adjuvant treatment prior to radiotherapy in patients with high-risk localised or locally advanced hormone dependent prostate cancer . |

| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
