Table 1 IC 50 values of P2Et fraction, gallic acid, and doxorubicin in 4T1 and normal cells (gingival fibroblasts and PBMC) estimated using the MTT assay

From: Gallotannin-rich Caesalpinia spinosa fraction decreases the primary tumor and factors associated with poor prognosis in a murine breast cancer model

  IC50values after treatment with the following compounds
Cell Type P2Et fraction* Gallic acid* Doxorubicin*
4T1 34.1 ± 1.6 96.2 ± 0.0 0.5 ± 0.1
PBMC + PHA > 125 ± 1.0 ND 2023 ± 0.2
Fibroblasts > 125 ± 1.0 ND 0.4 ± 0.1
  1. *Concentration (μg/mL) ± SEM.
  2. ND = not done.
