Vosoritide (BMN-111; Voxzogo) is a peptide-based C-type natriuretic peptide (CNP) analogue approved in 2021 for the treatment of childhood achondroplasia. Vosoritide acts by binding to a receptor (target) called natriuretic peptide receptor type B (NPR-B), which reduces the activity of fibroblast growth factor receptor 3 (FGFR3). It is a peptide consisting of the amino acids proline and glycine plus the 37 C-terminal amino acids from natural human CNP. The complete peptide sequence is: PGQEHPNARK YKGANKKGLS KGCFGLKLDR IGSMSGLGC.

Biological Activity
| ln Vitro | In chondrocytes, vosoritide (0.1 μM; 1 hour) decreases NPR2 phosphorylation [2]. In cultured Fgfr3Y367C/+ femurs, voyoritide (0.1 μM; 6 days) enhances chondrocyte differentiation and augments proliferative growth plate area [2]. Vosoritide (10 μM; overnight) decreases ACH growth plate chondrocytes' ERK1/2 activation [3]. |
| ln Vivo | Vosoritide (subcutaneous injection; 800 μg/kg; once daily; 20 days) therapy improves skeletal measures in mice with Fgfr3 gain-of-function mutations [3]. |
| Cell Assay |
Western Blot Analysis[2] Cell Types: Chondrocyte Culture Tested Concentrations: 0.1 μM Incubation Duration: 1 hour Experimental Results: Result in diminished NPR2 phosphorylation. Western Blot Analysis[3] Cell Types: Chondrocytes Tested Concentrations: 10 μM Incubation Duration: Overnight Experimental Results: Prevents FGF-mediated increase in ERK1/2 phosphorylation. |
| Animal Protocol |
Animal/Disease Models: Fgfr3Y367C/+ mice[3] Doses: 800 μg/kg Route of Administration: subcutaneous injection; 800 μg/kg; one time/day; 20 days Experimental Results: Observed phenotypic changes include skull flattening, snout Elongation, front crossbite improvement, claws and fingers enlarged, tibia and femur lengthened and straightened. |

Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| 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. Injection Formulation 5: 2-Hydroxypropyl-β-cyclodextrin : Saline = 50 : 50 (i.e. 500 μL 2-Hydroxypropyl-β-cyclodextrin → 500 μL Saline) Injection Formulation 6: DMSO : PEG300 : castor oil : Saline = 5 : 10 : 20 : 65 (i.e. 50 μL DMSO → 100 μLPEG300 → 200 μL castor oil → 650 μL Saline) Injection Formulation 7: Ethanol : Cremophor : Saline = 10： 10 : 80 (i.e. 100 μL Ethanol → 100 μL Cremophor → 800 μL Saline) Injection Formulation 8: Dissolve in Cremophor/Ethanol (50 : 50), then diluted by Saline Injection Formulation 9: EtOH : Corn oil = 10 : 90 (i.e. 100 μL EtOH → 900 μL Corn oil) Injection Formulation 10: EtOH : PEG300：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL EtOH → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Oral Formulations Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals). 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.) |
