Biological Activity
| Targets | HSPA5 |
| ln Vitro | At a binding concentration of 25 μM, HM03 (0.1-50 μM; 72 hours) shows over 50% inhibition in HCT116 cells [1]. When combined with HSPA5 and HSPA9, HM03 forms more sensitive cells than other HSP70 proteins. |
| Cell Assay |
Cell Viability Assay[1] Cell Types: HCT116 cells Tested Concentrations: 0.1, 1, 10, 25, 50 μM Incubation Time [1]. Incubation Duration: 72 hrs (hours) Experimental Results: Demonstrated significant inhibitory effect (18% survival rate at 25 µM). |

Solubility Data
| Solubility (In Vitro) | DMSO: ~125 mg/mL (~270.0 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 6.25 mg/mL (13.50 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 62.5 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.) |
