１生で、かつ優れた制癌活性を有する制癌剤の開発が望
まれていた。(Prior art) Conventionally, cancer chemotherapy agents include alkylating agents (nitrogien mustards, ethyleneimines, sulfonic acid esters, etc.), antimetabolites (folate antagonists, pyrimidine antagonists, etc.), and plant-based Before nuclear fission (colcemid, vinblastine, etc.), antibiotics (sarcomycin, carcinophilin, mitomycin, etc.), hormonal agents (corticosteroids, male hormones, female hormones, etc.), and porphyrin complex salts (morphilin, copp), etc. Used clinically. However, most of these cancer chemotherapeutic agents are cytotoxic substances and have the problem of exhibiting serious side effects depending on the dosage and administration method. Therefore, it has been desired to develop an anticancer agent that is low in toxicity and has excellent anticancer activity.
一方、癌細胞は正常細胞が分化の途中で未分化のまま増
殖を繰り返すものであるという認識から、これら未分化
癌細胞を何らかの刺激によって分化させることができれ
ば癌治療に応用できるものと期待される。On the other hand, based on the recognition that cancer cells are normal cells that repeatedly proliferate while remaining undifferentiated during the differentiation process, it is expected that if these undifferentiated cancer cells can be differentiated by some kind of stimulation, it will be possible to apply them to cancer treatment. .
