Background

β-Defensin-1 is a peptide with antimicrobial properties that protects the skin and mucosal membranes of the respiratory, genitourinary, and gastrointestinal tracts.1 It inhibits the growth of B. adolescentis, L. acidophilus, B. breve, B. vulgatus, L. fermentum, B. longum, and S. thermophilus in an antimicrobial radial diffusion assay.2 β-Defensin-1 also inhibits the growth of periodontopathogenic and cariogenic bacteria, including P. gingivalis and S. salivarius, and of susceptible M. tuberculosis H37Rv but not of resistant M. tuberculosis RM22 when used at a concentration of 128 µg/ml.3,4 It blocks human and mouse Kv1.3 voltage-gated potassium channels (IC50s = 11.8 and 13.2 μM, respectively).5 Overexpression of β-defensin-1 in the human oral squamous cell carcinoma (OSCC) cell lines HSC-3, UM-1, and SCC-9 increases migration and invasion but not proliferation.6

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.
