Biological Activity
| ln Vivo | Trestolone is utilized in the form of trestolone acetate, an intramuscular injection that serves as a persistent prodrug of trestolone. |
| Additional Infomation |
Trestolone (7α-methyl-19-nortestosterone) is a synthetic androgen developed by the Population Council as a potential candidate drug for use in hormonal male contraceptive methods. In males, regular administration of sufficient quantities of trestolone induces a state of temporary infertility. Drug Indication Investigated for use/treatment in contraception and male hormonal deficiencies/abnormalities. Mechanism of Action Trestolone is a potent inhibitor of the release of the luteinizing hormone (LH) and follicle stimulating hormone (FSH). As spermatogenesis requires both testosterone and FSH, it is impaired by the reduction in FSH caused by trestolone as well as the reduction in LH, and subsequent reduction in testosterone. |
Solubility Data
| Solubility (In Vitro) | DMSO: 100 mg/mL (346.72 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (8.67 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (8.67 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: 2.5 mg/mL (8.67 mM) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
