This kind of substance was originally separated from podophyllum resin and has been noticed for its inhibitory effect on tumor cells.
[pharmacological action] the action of podophyllin is similar to colchicine. It is very sensitive to experimental sarcoma and cancer cells, but it is not used as an anticancer agent because of its great toxicity to human normal cells (podophyllin derivatives are used as anticancer agents in clinic). When applied to skin, it can cause abnormal division of basal epidermal cells, degeneration of protoplast and nucleus. The oil solvent or alcohol solvent can be used to remove condyloma acuminatum or mastoid wart. At this time, attention should be paid not to make the liquid contact with healthy skin. Oral administration of podophyllum cable or podophyllum resin can stimulate the small intestine and produce a large amount of watery diarrhea, which belongs to resin cathartic; at this time, it is often accompanied by abdominal pain, large amount, and even bloody stool, or lead to severe exhaustion collapse. Injection of podophyllin has great toxicity, which first shows its stimulating effect on the central nervous system. The sensitivity of animals to podophyllin is different. Cat is the most sensitive, and it is easy to cause vomiting and diarrhea (chlorpromazine has some preventive effect on these toxic reactions); rats, guinea pigs and dogs are less sensitive. Except guinea pig and duodenum. In mice (sensitized by allogeneic red blood cells), podophyllin has the effect of immunosuppression. After injection, some metabolites were excreted in urine, but not in original form. Daily subcutaneous injection can produce accumulation effect.
