This animal died within 2 hours of test substance administration.
Clinical signs:
other: 175 mg/kg (2 animals): Both animals appeared active and healthy during the study - there were no adverse clinical signs, signs of gross toxicity or abnormal behaviour. 550 mg/kg (3 animals): Clinical signs noted prior to death included hypoactivity, pro
Gross pathology:
175 mg/kg (2 animals):
There were no abnormalities noted at necropsy.

550 mg/kg (3 animals):
Gross necropsy of the decedents revealed discoloration of the intestines. No gross abnormalities were noted for the euthanized animal necropsied at the conclusion of the 14 -day observation period.

2,000 mg/kg (1 animal):
Clinical signs noted prior to death included hypoactivity, hunched posture and piloerection.

Applicant's summary and conclusion

Interpretation of results:
harmful
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
XU-12314.00 appears to have moderate to low acute toxicity, with an LD50 of approximately 550 mg/kg.
Executive summary:

An acute oral toxicity test (Up and Down Procedure) was conducted with Fischer 344 rats to determine the potential for XU-12314.00 to produce toxicity from a single dose via the oral route. Under the conditions of this study, the acute oral LD50 of XU-12314.00 was estimated to be 550 mg/kg (the one dose with partial response) of body weight in female rats with a 95% PL confidence interval of 88.94 mg/kg (lower) to 2,430 mg/kg (upper).
