Abstract
For evaluating the mutagenic potential of 2-carbomethoxy-4-chlorodiethyl phosphate, three different short-term mutagenicity tests were used; Salmonella typhimurium preincubation assay with and without rat liver microsomal activation, chromosome aberration test in cultured chinese hamster lung fibroblast cell and in vivo micronucleus test in male mice bone marrow. In Salmonella typhimurium reverse mutation assay using TA98, TA100, TAl535 and TAl537, 2-carbomethoxy-4-chlorodiethyl phosphate did not show any mutagenic response in the presence and absence of S9 mix. It did not induce any significant structural chromosome aberrations in the absence of metabolic activation. In micronucleus test using ICR mice, the frequency of micronucleated polychromatic erythrocytes (MNPCE) increased in bone marrow cells treated with positive control, mitomycin-C, but 2-carbomethoxy-4-chlorodiethyl phosphate did not increase micronucleated polychromatic erythrocytes. These results indicate that 2-carbomethoxy-4-chlorodiethyl phosphate does not show any positive responses in short-term genotoxicity assays.
벼멸구에 대해 살충성이 있는 2-carbomethoxy-4-chlorodiethyl phosphate를 신농약으로 개발할 목적으로 변이원성 시험, 즉 유전자복귀돌연변이, 염색체이상 및 소핵시험을 수행하였다. Salmonella typhimurium을 이용한 복귀돌연변이원성을 TA1535, TA1537, TA98과 TA100 균주를 이용하여 시험한 결과 대사활성화물질(S-9mix)의 첨가여부에 관계없이 유전자에 이상을 미치지 않았으며, CHL세포에 대한 세포독성은 EMEM 배지에서
