摘要

Aseries of 40- N- substituted (aminomethyl) benzoate derivatives of scutellarein were designed and synthesized. Evaluation of their physiochemical properties showed that the designed target compounds 5a- e exhibit higher chemical stability and aqueous solubility than scutellarin and scutellarein. The permeability (Papp AP to BL) of 5c- e in Caco- 2 cells were 2.8, 8.1, and 12.6 times higher than that of scutellarin and 1.3, 4.1, and 6.0 times higher than that of scutellarein; especially, 5e had the highest Papp AP to BL value (7.19 0.31 x 10- 6 cm/ s) and the lowest ER (Papp BL to AP/ Papp AP to BL) value of 0.17. In vitro antioxidative evaluation results revealed that 5e could protect against H2O2- induced PC12 cells' oxidative damage by attenuating mitochondrial membrane potential loss and decreasing H2O2- induced reactive oxygen species (ROS) production.
