Abstract

PURPOSE:To provide a cell differentiation inducing agent composed of cotylenin C and useful in clinical field as a carcinostatic agent, antimyodystrophic agent, etc. CONSTITUTION:A bacterial strain (strain 501-7W) supposed as a new species of the genus Cladosporium is cultured in a medium containing 3% sucrose, 0.5% peptone and 0.5% corn steep at 28 deg.C for 6 days under shaking. The filtrate of the obtained culture product is extracted with ethyl acetate and the extract is concentrated in vacuum and subjected to silica gel column chromatography (trichloromethane : ethanol = 100 : 4) to obtain a cell differentiation inducing agent consisting of cotylenin C of formula. The compound exhibits carcinostatic effect by the differentiation induction of a cancer cell to a normal cell, has low side actions and is useful for the treatment. The daily dose of the compound for adult is preferably l-100mg for intravenous administration and 5-500mg for oral administration.

(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.
