Biological Activity


ln Vivo Acyline (50 μg, sc, twice daily, 5 days) TFA disrupted vaginal estrus, decreased uterine weight, and increased luteinizing hormone concentrations in female rats that were Kiss1−/− and Gpr54−/−. decrease[1]. Acyline (50 μg, sc, once) TFA lowers the amounts of follicle-stimulating growth hormone in male Kiss1−/− and Gpr54−/− cells.
Animal Protocol Animal/Disease Models: Female Kiss1−/−and Gpr54−/− mice[1]
Doses: 50 μg (1 mg/mL in PBS)
Route of Administration: subcutaneous (sc) injection; twice (two times) daily; 5 days
Experimental Results: 12 Kiss1−/− mice left oestrus within 4 days of 13 mice received acyline while only 2 of 17 mice received vehicle left oestrus. Also, 7 of 8 Gpr54−/− mice received acyline left oestrus compared to 1 of 7 received vehicle. decreased uterine weights of Kiss1−/−and Gpr54 −/− mice in treated group compared to the vehicle group, and decreased serum LH concentrations in Kiss1−/− mice.

Solubility Data


Solubility (In Vitro) DMSO :~100 mg/mL (~60.71 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 2.5 mg/mL (1.52 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% 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 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 (1.52 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.

 (Please use freshly prepared in vivo formulations for optimal results.)

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
