Figure 1. P22077 does not affect cell viability. (A) The chemical structure of P22077. (B, C) The cytotoxicity of P22077 in Raw264.7 cells (B) and mouse peritoneal macrophages (PM) (C). (D) Raw264.7 cells and peritoneal macrophages plated treated by different concentrations of P22077 for 12h, the morphology of the cells observed under the microscope. Scale bars, 100μm. Similar results were obtained from three independent experiments and data were presented as mean ± SD of one representative experiment.
