NK7-902 diTFA
Based on 1 Customer Validation
NK7-902 diTFA is a selective and orally active CRBN-dependent NEK7 molecular glue degrader with Kd values of 1.5 and 2.6 μM for hNEK7 and mNEK7. NK7-902 diTFA fully degrades NEK7 in human primary monocytes and whole blood but only partially inhibits NLRP3-dependent IL-1β production. NK7-902 diTFA shows activity in murine systems and induces a profound and long-lasting NEK7 degradation but only transiently blocks NLRP3 inflammasome activation. NK7-902 diTFA can be used for the research of inflammation, such as cryopyrin-associated periodic syndromes.

NK7-902 diTFA (0.005-10000 nM; 18 h pre-treatment) potently and selectively degrades NEK7 (DC50 = 0.2 nM) in human primary monocytes, with partial, stimulus-dependent inhibition of NLRP3 inflammasome-mediated IL-1β secretion[1].
NK7-902 diTFA (0.009-10000 nM; 18 h) potently degrades NEK7 (DC50 = 1.6 nM) in human PBMCs, with full NLRP3 inflammasome inhibition in most CAPS mutations but partial inhibition in the NEK7T348M mutation[1].
NK7-902 diTFA (0.001-10000 nM; 18 h) potently degrades NEK7 in human whole blood (DC50 = 8.7 nM) and neutrophils, with partial IL-1β inhibition in whole blood but full inhibition in isolated neutrophils[1].
NK7-902 diTFA (1-10000 nM; 18 h) potently degrades NEK7 (DC50 = 54.2 nM) in mouse primary splenocytes in a CRBN-dependent manner[1].
NK7-902 diTFA (0.1-10000 nM; 18 h) potently degrades NEK7 (DC50 = 4.1 nM) in NHP blood in vitro[1].
NK7-902 diTFA (20-411 μg/mL; 96 h) degrades NEK7 in human primary blood lymphocytes without inducing significant chromosomal damage or cell cycle delay[1].

NK7-902 diTFA (300 mg/kg; p.o.; single dose; 16h pre-LPS challenge) induces robust NEK7 degradation and significant inhibition of NLRP3 inflammasome-mediated IL-1β release in a mouse CAPS model[1].
NK7-902 diTFA (0.2-2 mg/kg; p.o.; single dose) induces profound, long-lasting NEK7 degradation but only transient IL-1β inhibition in non-human primates[1].

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 (3.92 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)
