Biological Activity
Lactupicrin (0.25-1 μM, 24 h) attenuates cholesterol influx into low-grade inflammatory macrophages by targeting LOX-1[2].
Lactupicrin (0.625-40 μM, 24 h) reduces NF-κB activities in inflammated macrophages[3].
Lactupicrin (40 μM, 24 h) inhibits p65 nuclear translocation by downregulation of cytoplasmic dynein-mediated transport of p65 in inflammated macrophages[3].
Lactupicrin (50 μg/L, 48 h) completely prevents parasite growth[4].
Lactupicrin (10-1000 μM, 45 min) exhibits AChE inhibition dose-dependently [4].

Lactupicrin (1.2-120 mg/kg, p.o., daily, 12 weeks) limits macrophage foam cell formation through a reduction of LOX-1 in lipid rafts, contributing to its atheroprotective effect in ApoE-/- mice[2].
Lactupicrin (1.2-120 mg/kg, p.o., daily, 12 weeks) inhibits early atherosclerosis formation in ApoE-/-mice[3].
Lactupicrin (1.2-120 mg/kg, p.o., daily, 12 weeks) reduces ApoE-/-mice serum levels of IL-1β and TNF-α but not IL-6 dose-dependently[3].

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
