- Abstract: The anticancer agent's FT-207, N1-(2'-tetrahydrofuryl)-5-fluorouracil, a derivative of 5FU (5-fluorouracil), induced chromosome damage to the human leukocyte was investigated. FT-207 inhibit mitosis and cause chromatid and chromosome breakage and chromatid exchange with 20 ug/ml for 48 to 72 hours of treatment. However, with 15 ug/ml for 72 hours only delayed spiralization was produced in some of the chromosomes in the same cells. The random distribution of chromosome breakage were observed and the effect of FT-207 on the chromosomes of human leukocytes were time dependent rather than concentration dependent. The comparision of the effect of mitomycin C on human leukocytes and the action of FT-207 at specific times during the cell cycle were discussed.
