测试了三种癌症化学预防候选药物CP-31398(细胞可渗透的苯乙烯基喹唑啉p53调节剂)、SHetA 2(柔性杂芳族维甲酸)和磷酸-布洛芬(PI,布洛芬的衍生物)的遗传毒性活性。在沙门氏菌/大肠杆菌/微粒体平板掺入试验中,所有化合物均无致突变性。在存在或不存在大鼠肝S9(S9)的情况下,CP-31398和SHEtA 2均未诱导中国仓鼠卵巢(CHO)细胞中的染色体畸变(CA)。PI在CHO细胞中诱导CA,但仅在存在S9的情况下。在存在S9的情况下,在CHO细胞中检测PI、其母体化合物布洛芬及其部分二乙氧基磷酰氧基丁醇(DEPBA)的CA和微核(MN)。在存在≤100 μg/ml S9的情况下,PI可诱导CA和MN(Kin+和Kin-)。免疫组化检测CA为阴性,Kin+浓度为250 μg/ml时检测MN为阳性,Kin−浓度为125和250 μg/ml时检测MN为阳性。DEPBA在≤5000 μg/ml时既不诱导CA也不诱导MN。在存在S9的情况下,PI处理的CHO细胞中诱导染色体损伤可能是由于其代谢产物。在存在或不存在S9的情况下,在GADD 45 α-GFP Human GreenScreen试验中,所有化合物均无遗传毒性,并且在小鼠骨髓红细胞中均未诱导MN。
The genotoxic activities of three cancer chemopreventive drug candidates, CP-31398 (a cell permeable styrylquinazoline p53 modulator, SHetA2 (a flexible heteroarotinoid), and phospho-ibuprofen (PI, a derivative of ibuprofen) were tested. None of the compounds were mutagenic in the Salmonella/Escherichia coli/microsome plate incorporation test. CP-31398 and SHetA2 did not induce chromosomal aberrations (CA) in Chinese hamster ovary (CHO) cells, either in the presence or absence of rat hepatic S9 (S9). PI induced CA in CHO cells, but only in the presence of S9. PI, its parent compound ibuprofen, and its moiety diethoxyphosphoryloxybutyl alcohol (DEPBA) were tested for CA and micronuclei (MN) in CHO cells in the presence of S9. PI induced CA as well as MN, both kinetochore-positive (Kin+) and -negative (Kin−), in the presence of S9 at ≤100 μg/ml. Ibuprofen was negative for CA, positive for MN with Kin+ at 250 μg/ml, and positive for MN with Kin− at 125 and 250 μg/ml. DEPBA induced neither CA nor MN at ≤5000 μg/ml. The induction of chromosomal damage in PI-treated CHO cells in the presence of S9 may be due to its metabolites. None of the compounds were genotoxic, in the presence or absence of S9, in the GADD45α-GFP Human GreenScreen assay and none induced MN in mouse bone marrow erythrocytes.
