Product Description
Vocacapsaicin (CA-008), the precursor of capsaicin, is the first non-opioid TRPV1 agonist. Vocacapsaicin provides long-lasting pain relief.
Biological Activity I Assay Protocols (From Reference)
Targets
TRPV1
ln Vitro
Vocacapsaicin (CA-008, Conentric Analgesics) – an investigational TRPV agonist being studied for long-lasting pain – works through the same TRPV1 agonism mechanism but its localized delivery is thought to minimize activation of a large array of neurons, such as capsaicin topical products[1].
ln Vivo
When injected into surgical sites, vocacapsaicin is rapidly converted to lipophilic capsaicin and can cross the membranes to reach the desired amino acid target on TRVP1 channels[1].

Additional Infomation
recently completed phase II clinical trial of vocacapsaicin showed that the drug significantly reduced pain in patients undergoing total knee arthroplasty (TKA). The study was randomized, double-blind, placebo-controlled. All TKA patients received standard treatment, including spinal anesthesia, ketorolac, acetaminophen, and ropivacaine (administered via intra-articular block, femoral nerve block, and IPACK block, respectively). Two intervention groups received 36 mg vocacapsaicin (n = 61) and 60 mg vocacapsaicin (n = 62), respectively, via surgical site infiltration. The control group (n = 64) received standard treatment and, as needed, opioid analgesia. The primary efficacy endpoint was pain reduction recorded using the Numerical Rating Scale (NRS). The NRS uses an 11-point scale, with 0 indicating no pain and 10 indicating unbearable pain. Patients verbally selected a number based on their pain level over the past 24 hours. Table I shows pain relief at rest after administration of 36 mg vocacapsaicin. Table II shows pain relief during activity after administration of 36 mg vocacapsaicin. Opioid usage was significantly reduced in the vocacapsaicin 36 mg group at 96 and 168 hours post-administration. Concentric Analgesics noted that the 36 mg vocacapsaicin was consistently more effective than the 60 mg vocacapsaicin. Regarding side effects, parameters appeared consistent between the intervention and control groups. No local or systemic safety issues were observed in the Phase II trial.¹⁴ As this research paper has not yet been published, further data interpretation, including inclusion and exclusion criteria, AUC definition, specific adverse events, and their incidence, is not available. We welcome further information to fully evaluate the use of this therapy.

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.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 2.1757 mL 10.8786 mL 21.7571 mL
5 mM 0.4351 mL 2.1757 mL 4.3514 mL
10 mM 0.2176 mL 1.0879 mL 2.1757 mL

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
