Boc-MLF TFA
Based on 4 publication(s) in Google Scholar
Boc-MLF TFA (Boc-Met-Leu-Phe-OH TFA) is a competitive FPR1 antagonist. Boc-MLF TFA inhibits fMLF-induced neutrophil activation through FPR. Boc-MLF TFA inhibits receptor-induced inflammation and cell migration. Boc-MLF TFA inhibits amniotic epithelial-mesenchymal transition. Boc-MLF TFA reduces pro-inflammatory cytokine levels. Boc-MLF TFA increases collagen expression in fetal membranes. Boc-MLF TFA reverses fetal membrane epithelial cell collapse, increases villi, and reduces mucus attachment. Boc-MLF TFA can be used in research on premature rupture of fetal membranes.

Biological Activity
Description
In Vitro
Boc-MLF TFA acts as a fairly specific FPR antagonist in human neutrophils, inhibiting fMLF-induced NADPH oxidase activity while only slightly affecting WKYMVM-induced activity[1].

Result:In the LPS+BOC-MLF group, FPR1 expression in fetal membranes was decreased compared with the LPS group.
IL-6 levels in cardiac blood were decreased compared with the LPS group.
EMT was reversed compared with the LPS group, with changes in E-Cad and Vimentin expression opposite to those in the LPS group.
Collagen expression in fetal membranes was increased compared with the LPS group.
Scanning electron microscopy showed reversal of LPS effects, with slight plumping of fetal membrane epithelial cells, increased villi, and no obvious mucus.

Solvent & Solubility
In Vitro:
DMSO : 150 mg/mL (240.51 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.01 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.01 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
