Figure Lengend Snippet: Docking results and interactions of cathepsin H with ( A ) SSR 69071 ( B ) PF429242 , in 3D and 2D formats

Article Snippet: SSR 69071 and PF429242 (MedChemExpress, USA) were dissolved in 0.1% dimethyl sulfoxide (DMSO, MP Biomedicals, USA) and ultrapure water, respectively, to prepare stock solutions, then serially diluted with complete medium to working concentrations (SSR 69071, 0.001–10 μΜ/mL; PF429242 , 2.5–40 μM/mL) for 24-h treatment.
