Biological Activity
| ln Vitro | 5-LOX-IN-2 (Compound 10b) has a cytotoxic effect on renal cancer cells and is specific to RCC4 and 786.0 cells that lack the Von Hippel-Lindau (VHL) inhibitory oncogene. In RCC4 cells, 5-LOX-IN-2 (Compound 10b) (0-10 μM; 24 hours) can also upregulate p62 and LC3B expression, inhibit autophagy carriers, and promote cell proliferation through activation of the caspase-3 pathway. 1]. |
| Cell Assay |
Cell viability assay [1] Cell Types: RCC4, RCC10, 786.0 Cell Tested Concentrations: 0-100 μM Incubation Duration: 4 days Experimental Results: The cell viability of renal cancer cells is diminished and the selectivity is stronger. RCC4 and 786.0 cells lack the Von Hippel-Lindau (VHL) tumor suppressor gene. Western Blot Analysis[1] Cell Types: RCC4, RCC10, 786.0 Cell Tested Concentrations: 0-10 μM Incubation Duration: 24 hrs (hours) Experimental Results: LC3B and p62 expression increased and autophagy flow was blocked in RCC4 cells. Cleavage of caspase-3 precursors was stimulated in a dose-dependent manner only in RCC4 cells lacking the VHL tumor suppressor. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~351.73 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.79 mM) (saturation unknown) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (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 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 + to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |
