S29434 (NMDPEF) is a potent, competitive, selective and cell membrane-permeable inhibitor of quinone reductase 2 (QR2), with IC50s ranging from 5 to 16 nM for human QR2 at different organizational levels, and has good selectivity for QR2 over QR1. S29434 (NMDPEF) induces autophay and inhibits QR2-mediated ROS production.

Solubility Data
| Solubility (In Vitro) | DMSO : ~19.29 mg/mL (~51.52 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1.93 mg/mL (5.16 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 19.3 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
