Molecular structure of MCL and its cytotoxicity. (a) Schematic diagram of DMAMCL synthesis from PTL and the mechanism of sustainable release of MCL by DMAMCL under neutral conditions. (b) The MTT reagent was used to assess the cytotoxicity of different concentrations (0, 1, 1.25, 2.5, 5, 10, and 20 μM) of MCL in NRK-52E cells after 48 h of exposure. ∗P < 0.05 versus normal controls.
