- Abstract: Aim To study the nephrotoxicity effects of the main monomers in Zuojin Pills. Methods CCK-8 and high-content toxicity screening were used to preliminarily screen the main alkaloids in Zuojin Pills that may cause renal cell damage. Further, by confirmation of cell morphology, release rate of lactate dehydrogenase and cytochrome C, and expression of apoptosis-related proteins, the alkaloids causing cell damage were preliminarily identified, providing in vitro toxicological evidence for the compatibility of components of traditional Chinese medicine and compatibility attenuation. Results Preliminary screening using CCK-8 method and high-content technology showed that evodiamine (EVO) could significantly reduce cell number, increase cell membrane permeability, and reduce mitochondrial membrane potential. In addition, cell morphology, apoptosis and cytochrome C expression were consistent with the results of high-content screening. Western blot experiments indicate that EVO could induce apoptosis and cause renal cell damage. Conclusions EVO can obviously cause renal cell damage, and may induce apoptosis by affecting mitochondria, cytochrome C and cell membrane permeability.
