| ln Vitro |
In young Salmonella mansoni, clonazepam first results in severe spastic paralysis [2].

|---|---|
| ln Vivo |
In gerbils, meclonazepam (0.1–5.6 mg/kg) exhibits anxiolytic effects [1]. The effects of clonazepam (40 and 80 mg/kg) on immature schistosomiasis are highly notable [2].

| Animal Protocol |
Animal/Disease Models: Adult experimental naive male Mongolian gerbil (Meriones unguiculatus) [1]
Doses: 0.1, 0.3, 1.0, 3.0, 5.6 mg/kg Route of Administration: intraperitonealadministration 5 minutes before the start of training. Experimental Results: ED50 5 minutes post injection (pi) was 0.77-0.78 mg/kg. Animal/Disease Models: CB6F1 mice infected with single-sex male Salmonella mansoni cercariae 28 days before treatment [2] Doses: 40 and 80 mg/kg Route of Administration: administered by gavage, either as a single agent or as a A sequence of 1 dose of praziquantel (PZQ) was administered 5 minutes apart, followed by a dose of Ro followed by a 15 minute interval between the second dose of PZQ. Experimental Results: PZQ had no obvious effect on immature schistosomiasis, while Ro 11-3128 was highly effective. |

| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (7.58 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 (7.58 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.) |

*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.
