Bimatoprost grenod (NCX 470) is a second generation NO donor prostaglandin analog. Bimatoprost grenod effectively reduces intraocular pressure in animal models of ocular hypertension and glaucoma by activating diprost-mediated uveal efflux and NO-mediated conventional efflux. Bimatoprost grenod may be used in studies investigating vascular hypertension and glaucoma. Yes Yes

Biological Activity

ln Vivo	In well-researched animal models of glaucoma and ocular hypertension, bimatoprost grenod has superior intraocular pressure-lowering effectiveness than equimolar dosages of bimatoprost[1]. Bimatoprost grenod (0.14% 30 μL; once-dose instillation) lowers intraocular pressure in rabbits with transitory ocular hypertension[2]. At eighteen hours after dosage, bimatoprost grenod (0.042% 30 μL; instillation; once) is more efficacious than equimolar bimatoprost in normotensive dogs (ONT-dogs) and cynomolgus monkeys with laser-induced ocular hypertension (OHT-monkeys)[2].
Animal Protocol	Animal/Disease Models: New Zealand white rabbits with 0.1 mL 5% sodium chloride solution injection[2] Doses: 0.14% Route of Administration: Instillation; 0.14% 30 μL; once Experimental Results: Dramatically blunted the IOP rise throughout the experimental period in transiently ocular hypertensive New Zealand white rabbits.

Solubility (In Vivo)

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *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.

Oral Formulation 3: Dissolved in PEG400 Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose Oral Formulation 6: Mixing with food powders Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.  (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.
