Biological Activity

Description ML130 (Nodinitib-1) is a potent and selective inhibitor of NOD1 with IC50 of 0.56 μM, inhibits NF-κB activation, exhibits 36-fold selectivity over NOD2.
Targets
NOD1 [1]
0.56 μM
In vitro

ML130 has shown selective inhibition of NOD1-induced NF-κB activation in HEK293 cells with no cytotoxicity and is selected as a probe candidate molecule. ML130 is also confirmed in secondary assays by selectively inhibiting NOD1-dependent IL-8 secretion and also selectively inhibiting the NOD1-dependent pathway to NF-κB activation. [1] In another research, ML130 is proved to cause conformational changes of NOD1 in vitro and alter NOD1 subcellular targeting in cells, providing chemical probes for interrogating mechanisms regulating NOD1 activity and tools for exploring the roles of NOD1 in various infectious and inflammatory diseases.

Protocol (from reference)

Kinase Assay:[1]
  • NOD1 Dose Response assay:

    Day 1 Procedure 1) Harvest HEK-293-T NFKB-Luc at 100% confluency at 100% confluency. 2) Add NOD assay media with Multidrop. 3) Spin down plates at 1000 rpm for 1 min in centrifuge. 4) Serial compound dilutions. 5) Add gamma-tri-DAP to cell suspension at 0.75 ug/mL. 6) Seed 13000 cells/well in 4 uL/well to full plate HEK-293-T NFKB-Luc to TC-treated plate. 7) Spin down plates 500 RPM for 5 min on centrifuge. 8) Lid Plates. Sandwich 4 plates between 2 lidded 384 plates filled with H2O. 9) Wrap plates securely in single layer of Plastic Wrap. 10) Incubate overnight (14 hours) in 37 ℃ and 5% CO2 incubator. Day 2 Procedure 1) Add 3 ul/well of SteadyGlo solution with Multidrop. 2) Shake plates on a plate shaker for 20 min. 3) Spin plates 1000 RPM for 1 min using centrifuge. 4) Read luminescence.IC50 values are calculated using GraphPad Prism 5.0.The average Z' for the screen is 0.6, the signal to background is 11.1, signal to noise is 78.6 and signal to window is 6.0.
Cell Research:[1]
  • Cell lines: Fa2N-4 cells
  • Concentrations: 0.01 μM-50 μM
  • Incubation Time: 24 h
  • Method: Hepatic toxicity of compounds is determined with Fa2N-4 immortalized human hepatocytes using the ATP-lite 1-step assay. Fa2N-4 cells are seeded at 50,000 cells/well, and incubated with a range of concentrations of the test compound (0.01 µM-50 µM) in MFE support medium for 24 h at 37 ℃, 5% CO2. At the end of the experiment D-luciferin and luciferase are added. The emitted luminescent signal produced as a result of the reaction with cellular ATP is captured on the Infinite M200 plate reader. The concentration of each compound that killed 50% of the cells (LC50) is calculated by non-linear regression analysis using a log (inhibitior) vs response equation with a variable slope, using the statistic software package Prism4.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
