In comparison to the control group, the mean decrease in 5-HT in the jejunum was roughly 33%, 51%, and 66% at dosages of 15, 45, and 135 mg/kg/day, respectively, following oral administration of LX-1031 to mice. According to a preliminary report, LX-1031 at 100 mg/kg per day had reversible effects on 5-HT levels in the mice's jejunal mucosa within two days after stopping the medication [1]. In preclinical tests, LX-1031 dose-dependently decreased 5-HT expression in the ileum, jejunum, and duodenum but had no effect on brain 5-HT levels [2].

| Additional Infomation |
LX1031 is an orally-dosed drug candidate for irritable bowel syndrome and other gastrointestinal disorders. LX1031 was generated by Lexicon medicinal chemists, and its target was internally identified as a key control point for the regulation of peripheral serotonin levels. LX1031 is designed to act locally in the gastrointestinal tract by reducing the serotonin available for receptor activation, without affecting serotonin levels in the brain or its central nervous system functions.
Drug Indication Irritable bowel syndrome (IBS) and other gastrointestinal disorders Mechanism of Action LX1031 is designed to act locally in the gastrointestinal tract by reducing the serotonin available for receptor activation, without affecting serotonin levels in the brain or its central nervous system functions. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.64 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 (4.64 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

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
