Evaluation of XQ528 tartrate on embryo-fetus developmental toxicity in SD rats and genotoxicity.
The effects of XQ528 tartrate on the embryonic and fetal development of fertile Sprague-Dawley (SD) rats, along with their embryos and littermates, were evaluated using an embryo-fetus developmental toxicity assay. fertile SD rats exhibited no significant general toxic effects when administered doses of 0.25, 1.25, and 5.0 mg/kg intranasally from days 6 to 15 of gestation. The genotoxicity of the compound was evaluated through an amalgam of tests that included the Ames test, the Chinese hamster ovary (CHO) cell chromosome aberration test, and the micronucleus test in ICR mice. The results from the Ames test indicated non-mutagenicity at concentrations of 5000, 500, 50.0, 5.0, and 0.5 μg/dish across strains TA97, TA98, TA100, TA102, and TA1535. Additionally, the chromosomal aberration rates in CHO cells were not significantly altered at concentrations of 50.5, 101.0, and 202.0 μg/mL. No micronuclei induction was observed in ICR mice at dosage levels of 11.25, 22.50, and 45.00 mg/kg post intranasal administration. In conclusion, the no observed adverse effect level (NOAEL) for developmental toxicity of XQ528 tartrate in fertile SD rats, embryos, and littermates under the test conditions in this study was established at 5.0 mg/kg/day. Under these test conditions, XQ528 tartrate did not exhibit any significant genotoxic or carcinogenic potential.
期刊介绍:
Drug and Chemical Toxicology publishes full-length research papers, review articles and short communications that encompass a broad spectrum of toxicological data surrounding risk assessment and harmful exposure. Manuscripts are considered according to their relevance to the journal.
Topics include both descriptive and mechanics research that illustrates the risk assessment implications of exposure to toxic agents. Examples of suitable topics include toxicological studies, which are structural examinations on the effects of dose, metabolism, and statistical or mechanism-based approaches to risk assessment. New findings and methods, along with safety evaluations, are also acceptable. Special issues may be reserved to publish symposium summaries, reviews in toxicology, and overviews of the practical interpretation and application of toxicological data.
