Nangibotide (LR12) is a synthetic peptide and TREM-1 receptor inhibitor. Nangibotide inhibits NF-κB and NLRP3 inflammasome activation and reduces the release of pro-inflammatory factors (such as IL-1β, IL-8). Nangibotide inhibits Apoptosis. Nangibotide reduces excessive inflammatory responses and protects tissues (liver, lung) from damage. Nangibotide can be used in the researches for myocardial ischemia-reperfusion injury, septic shock, acute lung injury, osteoarthritis, and acute liver failure.

In Vitro

Nangibotide (50-100 μg/mL) significantly reverses TNF-α-induced inhibition of osteogenic differentiation, increasing alkaline phosphatase activity, calcium nodule formation, and Runx2, Osterix mRNA, and COL1A1 protein expression in MC3T3-E1 mouse osteoblasts^[2].
Nangibotide (10 ng/mL) promotes LO2 cell proliferation indirectly via CCL20 secretion from macrophages^[3].
Nangibotide (25-100 μg/mL; 24 h) significantly suppresses Porphyromonas gingivalis LPS (HY-D1056D)-induced TREM-1 mRNA, membrane-bound TREM-1, and soluble sTREM-1 expression in human primary monocytes, reducing IL-8, TNF-α, and IL-1β secretion^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Nangibotide (5 mg/kg; i.p.; every 2 days for 4 weeks) significantly attenuates cartilage degradation, improves subchondral bone microarchitecture, and inhibits osteoblast apoptosis in mice with ACLT-induced osteoarthritis^[2].
Nangibotide (5 mg/kg; i.v.; 1 h after TAA injection) promotes liver repair by improving the resolution of inflammation and liver regeneration in mice with Thioacetamide (HY-Y0698)-induced acute liver failure^[3].

Stock Solution Working Solution

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.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (1.86 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
