RESUMO
Objective This paper summarizes the research progress of biosynthesis and pharmacological effects of podophyllotoxin drugs,in order to provide reference for the wide application of these drugs.Methods The plant source,chemical structure,action mechanism and synthesis pathway of podophyllotoxin drugs were summarized.The pharmacological and toxicological characteristics and mechanisms of these drugs were discussed,and the research progress of new dosage forms of podophyllotoxin drugs was reviewed.Results Podophyllotoxin and its derivatives are important chemical constituents in the plants of the podophyllum,such as Dysosma versipellis,Diphylleia sinensis,Sinopodophyllum hexandrum.This kind of drug has few natural sources and can be artificially produced through chemical and biosynthetic pathways.Podophyllotoxin drugs have pharmacological effects such as anti-inflammatory,anti-tumor and anti-virus,but their toxic effects need to be paid attention to.Drugs can be transported by carriers to reduce toxicity and increase effect.Conclusion Podophyllotoxin drugs have broad clinical application prospects,and will be further studied and applied in the fields of anti-inflammatory,anti-tumor and anti-virus in the future.
RESUMO
Objective In this paper,the harmful effects and mechanisms induced by traditional Chinese medicine were expounded by combining the mechanism of programmed cell death and inflammatory reaction.It is expected to provide data support and theoretical reference for the rational use of traditional Chinese medicine and toxicology research.Methods By systematically analyzing the correlation between cell death and inflammatory response,the molecular mechanisms of pyroptosis,programmed cell necrosis and ferroptosis at home and abroad were summarized,and the harmful outcomes induced by traditional Chinese medicine were further discussed.Results Different toxic traditional Chinese medicines and their active ingredients have different tolerances to biological organisms.Programmed cell death is an important molecular mechanism for the toxicity of traditional Chinese medicines.Its signaling pathways are complex and diverse and are often accompanied by inflammatory reactions.Both of them have a certain effect on the toxic effects of traditional Chinese medicine.Conclusion Traditional Chinese medicine can provide inflammatory mediators for inflammatory response pathways through cell death or change the physiological balance of cells,thereby inducing inflammatory cascade reactions and promoting harmful outcomes in various systems of the body under the dual effects of cell death and inflammatory response.
