Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- The test animals were 8-10 week old healthy female Wistar Crl: WI(Han) (full barrier, SPF) rats. They were nulliparous and non-pregnant. Body weights on the day of administration ranged from 160 - 179 g. The rats were group housed in IVC cages (type III H) on Altromin saw fibre bedding, in an air-conditioned room maintained at a temperature of 22±3°C and relative humidity of 55±10%. There was a 12 hour light/dark cycle, and 10 air changes per hour. The rats were allowed free access to food (Altromin 1324 maintenance diet for rats and mice) and tap water, sulphur acidified to a pH value of approximately 2.8. Prior to test substance administration, food was withheld from the animals for 16 to 19 hours (access to water was allowed). Food was returned to the animals approximately 4 hours post-dosing. The rats were acclimatised to the laboratory conditions for at least five days.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Remarks:
- sterile water
- Details on oral exposure:
- Aqua ad injectionem (sterile water) was used as the vehicle. Homogeneity of the test material in the vehicle was maintained by vortexing the test solution for 30 minutes prior to each administration. The dosing volume was 10 mL/kg bw.
- Doses:
- Step 1 and 2: 2000 mg/kg bw
Step 3 and 4: 300 mg/kg bw - No. of animals per sex per dose:
- 3 female rats per Step
- Control animals:
- no
- Details on study design:
- The acute toxic class method was followed. The starting dose was 2000 mg/kg bw. No test material related mortality was recorded for any animal of Step 1, therefore a second step was performed at a dose of 2000 mg/kg bw. Mortality was noted at Step 2, therefore a third step was performed at 300 mg/kg bw. Based on the results obtained at Step 3, a fourth step was performed at 300 mg/kg bw. Surviving animals were observed for 14 days post-dosing. Clinical examinations were made several times on the day of dosing, at least once during the first 30 minutes and with special attention during the first 4 hours post-dose. Animals were observed for clinical signs once daily thereafter, until the end of the observation period. Body weights were recorded on Day 1 (prior to administration), and on Days 8 and 15 of the observation period. At the end of the 14 day observation period, survivors were sacrificed and subject to gross necropsy.

- Executive summary:
The acute oral toxicity of AAI_C18_PEHA_ACETATES was evaluated in female Wistar Crl: WI(Han) rats, according to the Acute Toxic Class method (OECD 423). The test material was dissolved in sterile water and administered to two groups of 3 females each at a dose of 2000 mg/kg bw, by gavage. A further two groups of 3 females each were administered a dose of 300 mg/kg bw by gavage. Animals were observed regularly within the first 4 hours after dosing for signs of toxicity and mortality. Daily observations were made for 14 days thereafter, and gross necropsy was performed on decedents or on survivors at the end of the observation period. Body weights were recorded on Day 1 (prior to administration), and on Days 8 and 15 of the observation period. There were no deaths in Step 1 animals administered 2000 mg/kg bw, however all 3 rats administered 2000 mg/kg bw in Step 2 died spontaneously on the day of dosing. No deaths were observed in the Step 3 and 4 animals administered 300 mg/kg bw. Relevant clinical findings in animals administered 2000 mg/kg bw included reduced spontaneous activity, piloerection, half eyelid-closure, bradykinesia, recumbency, catalepsis and kyphosis. All symptoms recovered by Day 2 for surviving animals. Relevant clinical findings in animals administered 300 mg/kg bw included reduced spontaneous activity, piloerection, half eyelid-closure, bradykinesia, moving the bedding, wasp waist and hunched posture. All symptoms recovered by Day 3. There were no effects on weight gain during the observation period, except for one animal which showed weight loss during the second week. No treatment-related macroscopic findings were observed.
Based on the results of the study, the LD50 cut-off value is considered to be 500 mg/kg bw.
