Camptothecin계 항암제 CKD-602의 유전독성평가
Genotoxicily Studies of An Anticancer Agent of Camptothecin Series, CKD-602
초록
To evaluate the genotoxicity of CKD-602, an anticancer agent the in viかo reverse mutation assay using Salmonella typhimurium, the Chromosome aberration assay using Chinese hamster lung (CHL) cells and the in vivo micronucleus assay using bone marrow cells of ddY mice were performed. In the reverse mutation assay, CKD-602 did not induced mutagenicity in Salmonella typhimurium TA 98, TA 100, TA 1535, and TA 1537 strains with and without metabolic activation. In the chromosome aberration test using CHL cells, there was an increased incidence of structural aberrations induced by CKD-602 without metabolic activation during 24 and 48 hours, but CKD-602 did not induce chromosome aberration with metabolic activation. The in vivo induction of micronuclei was measured in polychromatic erythrocytes of bone marrow of male ddY mice. At 24 hours after treatment with CED-602 by i.p. once, there was an increased incidence of micronucleated polychromatic erythrocytes in bone marrow of ddY male mice.
