Background

BAM-22P (8-22) is an endogenous neuropeptide derived from proenkephalin A and an agonist of MAS-related G protein-coupled receptor family member X1 (MRGPRX1), previously known as sensory neuron-specific G protein-coupled receptor 4 (SNSR4).1 It is involved in prurition and nociception. BAM-22P (8-22) induces calcium mobilization in HEK293S cells expressing human MRGPRX1 or SNSR3 (EC50s = 14 and 28 nM, respectively) and inhibits voltage-induced calcium currents in isolated rat neurons expressing human MRGPRX1 (EC50 = 0.6 µM).2 Intrathecal administration of BAM-22P (8-22) (30 nmol/animal) decreases the tail-flick latency in rats stimulated with the Gαi inhibitor pertussin toxin and increases the tail-flick latency in rats stimulated with the phospholipase C (PLC) inhibitor U-73122, indicating changes in pain sensitivity.3 BAM-22P (8-22) (100 µg/animal) increases scratching behavior in wild-type mice and enhances bile-duct ligation-induced scratching behavior in a mouse model of cholestasis.4

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
