Biological Activity
| ln Vitro | PAR1 agonists cause concentration-dependent increases in [Ca2+]i and neuronal ratios. In response to 10 μ m TF-NH2, 50–80% of the identified neurons showed the greatest increase in [Ca2+]i above basal values (peak 196.5±20.4 nM, n=25) [1]. Expression of E-cadherin was upregulated and vimentin was downregulated in SW620 cells cultured in TFLLR-NH2 activated platelet supernatants. A dose-dependent rise in TGF-β1 secreted by TFLLR-NH2 was found in the supernatant of an in vitro platelet culture system [2]. |
| ln Vivo | Rat paws were injected with TF-NH2, which caused a notable and long-lasting edema. Capsaicin and NK1R antagonist-induced sensory nerve ablation reduced edema by 44% in 1 hour and by 100% in 5 hours. TF-NH2 increased Evans blue extravasation 2- to 8-fold in the bladder, esophagus, stomach, intestine, and pancreas in wild-type mice, but not in PAR1−/− animals. Extravasation in the stomach, esophagus, and bladder can be completely eliminated by NK1R antagonists [1]. TFp-NH2 induced considerable contraction at 3-50 μM and significant relaxation at 0.3-50 μM in the absence of apamin. The concentration-response curve of TFp-NH2-induced contraction markedly moved to the left when 0.1 μM apamin inhibited TFp-NH2-induced relaxation [3]. |

Solubility Data
| Solubility (In Vitro) |
H2O : ~100 mg/mL (~131.26 mM) DMSO : ~100 mg/mL (~131.26 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (3.28 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (3.28 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. 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. Solubility in Formulation 3: ≥ 2.5 mg/mL (3.28 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 4: 33.33 mg/mL (43.75 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.  (Please use freshly prepared in vivo formulations for optimal results.) |
