| ln Vitro |
Felcisetrag contracts guinea pig colonic longitudinal muscle/myenteric plexus preparations (pEC50 = 8.6) and elevates cAMP in HEK-293 cells expressing h5-HT4(c) receptors (pEC50 = 9.3). In vitro tests reveal that felcisetrag has a moderate intrinsic action [1].
|
|---|---|
| ln Vivo |
Felcisetrag (0.03~3 mg/kg; subcutaneous injection) shortens the time needed for carmine dye excretion and accelerates its intestinal transit [1]. The esophagus relaxes in response to felcisetrag (0.03~10 mg/kg; administered intraduodenally) in a dose-dependent manner [1]. Felcisetrag (10 and 30 μg/kg; oral) improves the duodenum, jejunum, and gastric antrum's contractility [1].

| Animal Protocol |
Animal/Disease Models: guinea pig [1]
Doses: 0.03~3 mg/kg Route of Administration: subcutaneous injection Experimental Results: Increased colonic transport of carmine dye and shortened its excretion time. Animal/Disease Models: Rat[1] Doses: 0.03~10 mg/kg Route of Administration: Intraduodenal administration Experimental Results: Caused dose-dependent relaxation of esophagus. Animal/Disease Models: Dog [1] Doses: 10 and 30 μg/kg Route of Administration: Po Experimental Results: Increased contractility in the gastric antrum, duodenum and jejunum. |

| Additional Infomation |
Fecilevir (TD-8954) has been investigated for the treatment of enteral nutrition intolerance and gastrointestinal motility disorders. Fecilevir is a 5-hydroxytryptamine (5-HT) type 4 receptor agonist with potential gastrointestinal (GI) prokinetic effects. After administration, fecitrevir targets and binds to the 5-HT4 receptor, thereby enhancing its activity. This may enhance gastrointestinal motility, shorten transit time in the gastrointestinal tract and colon, and improve constipation.

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.49 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 (5.49 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. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (5.49 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*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.
