摘要: 目的:在已建立的良好实验室规范(GLP)平台,对真菌纤溶化合物1(FGFC1)进行系统的遗传毒性评估。方法:采用经典遗传毒性检测组合(Ames试验、体外培养CHO细胞染色体畸变试验和小鼠骨髓细胞微核试验)检测FGFC1的遗传毒性。结果:Ames试验结果提示,FGFC1在每皿0.5、5、50、500、1 000 mg 5个剂量下,在加和不加代谢活化系统(S9)时,对鼠伤寒沙门氏菌均无致突变性。CHO细胞染色体畸变试验结果提示,在终浓度62.5、125.0和250.0 mg/mL 3个剂量组,在加和不加S9时,于作用24 h和48 h的条件下培养的CHO细胞,均未诱发染色体畸变。小鼠骨髓细胞微核试验在62.5、125.0和250.0 mg/kg 3个剂量下对骨髓细胞的微核诱发率,与溶剂对照组比较差异均无统计学意义(P>0.05)。结论:在本实验条件下,未检测到FGFC1的遗传毒性和潜在致癌性。

Abstract: OBJECTIVE:To perform a systematic genotoxicity assessment of fungal fibrinolytic compound 1 (FGFC1) in an established GLP laboratory platform. METHODS:A combination of classical genotoxicity assays (Ames,in vitro culture CHO cell chromosome aberration and mouse bone marrow micronucleus assays) was used to detect genotoxicity of FGFC1. RESULTS:Results from the Ames assay indicate that FGFC1 was not mutagenic to Salmonella typhimurium at five doses of 0.5,5,50,500 and 1 000 g per dish,with and without the addition of the S9 metabolic activation system. FGFC1 did not induce chromosomal aberrations in the presence of S9 after 24 h and 48 h of treatments. The rates of micronucleus induction in bone marrow cells at 3 doses of 62.5,125.0 and 250.0 mg/kg was not significantly different from that in the solvent control group (P>0.05). CONCLUSION:The above results indicate that FGFC1 was not genotoxic and not potentially carcinogenic under the test conditions.
