Toxicological assessment is a mandatory research step in the development of new insecticidal drugs. At the All-Russian Research Institute of Veterinary Entomology and Arachnology, a prototype of the insecticidal bait Mukhnet IF was obtained with an active ingredient content of 0.06% ivermectin and 0.015% fipronil, which showed a highly effective effect against houseflies. This work presents the results of the study of acute oral toxicity of the above agent. For this, male white mice with a live weight of 16-26 g were selected. They were kept on a starvation diet for one day in individual houses with water. The drug was given in mg/kg body weight the next day. A total of 33 doses have been tested, ranging from 100 mg/kg to 40,000 mg/kg. The animals were observed for 14 days. According to the research results, it was revealed that at doses up to 20,000 mg/kg there were no signs of intoxication, but when tested at 25,000 mg/kg in some mice, these signs were noted, and at 30,000, 35,000 and 40,000 mg/kg deaths were recorded 20±10, 45±30 and 60±20%, respectively. It was not possible to test the drug over the last above dose due to incomplete eaten by mice. According to the degree of danger for warm-blooded animals, the drug belongs to the 4th class of low-hazard drugs (average lethal dose of 5000 mg/kg or more) in accordance with the classification of GOST 12.1.007-76. When analyzing the literature data on the toxicological characteristics of preparations containing ivermectin and chlorfenapyr, it was revealed that the insecticidal agent in its acute toxicity for warm-blooded animals is comparable to known analogues.

This study was based on determination of the antiulcer activity from methanol extract was prepared by using barks of pergularia extensa linn.. Priliminary investigations showed presence of saponins, terpenes, cardiac glycosides, alkaloids and sterols. Based on OECD-423 Guidelines, the pharmacology and acute oral toxicity studies were conducted by using methanolic extract. Ulcer development was prevented by Tannins because of their vasoconstriction effects and due to protein precipitation. Similarly, the Methanolic extract of Pergularia extensa Linn shows triterpenoids and saponins. The phytoconstituents are present in the extract and these could be possible agents which are involved in order to prevent gastric lesions induced by aspirin. When compared to ulcerative control groups, this Pergularia extensa Linn., shows a dose dependent curative ratio. The extracts exhibited an inhibition percentage of 27.18, 45.47 and 61.28 at doses of 100, 200 and 400mg/kg doses respectively.

Background: The natural antioxidants have an important role in the prevention of many diseases. The aim of study is to investigate phytochemical components, antioxidant activity and acute oral toxicity of Pomegranate (Punica granatum L.) fruit peel (PFP) extract. Materials and methods: Phytochemicals of PFP were determined by qualitative chemical tests, thin layer chromatography, total polyphenol and flavonoid contents. The PFP extract was evaluated for antioxidant activity by DPPH assay and MDA assay. In vivo acute oral toxicity test was conducted using Karber-Behrens method to determine LD50. Results: Results illustrated that PFP mainly contains flavonoids, alkaloids, tannins, triterpenes, saponins, and coumarins. PFP extract exhibited the total polyphenol and flavonoid contents with 189.97 mg gallic acid equivalent/g dry weight and 9.42 mg quercetin equivalent/g dry weight, respectively. The DPPH free radical scavenging and anti-lipid peroxidation activities of PFP extract were expressed with IC50 value of 4.80 μg/mL and 0.38 μg/ mL, sequentially. Simultaneously, the Dmax (the maximum dose administered to mice that no toxicity was observed) of PFP extract was determined to be 21.28 g/kg, equivalent to 35.64 g dried herb. Conclusion: The PFP extract is relatively safe and revealed high antioxidant activity. Key words: Punica granatum L.; polyphenols; flavonoids; gallic acid; quercetin; antioxidant activity; acute oral toxicity

By activating PPAR-γ, thiazolidinediones normalize glucose levels in animal models of type 2 diabetes and in patients with this pathology. The aim of the present study was to analyze 219 new derivatives in silico and select the best for synthesis, to be evaluated for acute oral toxicity in female rats and for control of diabetes-related parameters in a rat model of streptozotocin-induced diabetes. The best compound was chosen based on pharmacokinetic, pharmacodynamic, and toxicological parameters obtained in silico and binding orientation observed by docking simulations on PPAR-γ. Compound 1G was synthesized by a quick and easy Knoevenagel condensation. Acute oral toxicity was found at a dose greater than 2000 mg/Kg. Compound 1G apparently produces therapeutic effects similar to those of pioglitazone, decreasing glycaemia and triglyceride levels in diabetic animals, without liver damage. Moreover, it did not cause a significant weight gain and tended to reduce polydipsia and polyphagia, while diminishing systemic inflammation related to TNF-α and IL-6. It lowered the level of endogenous antioxidant molecules such as reduced glutathione and glutathione reductase. In conclusion, 1G may be a candidate for further testing as an euglycemic agent capable of preventing the complications of diabetes.
