Quantitative Structure−Activity Relationship Modeling of Rat Acute Toxicity by Oral Exposure

Quantitative structure-activity relationship modeling of acute toxicity of quaternary alkylammonium sulfobetaines to Daphnia magna.

The logarithm of the octanol/water partition coefficient has been widely used as the sole physicochemical property to define various types of biological activity, such as aquatic toxicity. In the present study, we derive a quantitative structure-activity relationship (QSAR) equation for the prediction of acute aquatic toxicity (48-h median effective concentration) of quaternary alkylammonium su...

Quantitative Structure-toxicity Relationship Modeling of Organic Compounds and Nanoparticles

Acute oral toxicity.

The purposes of acute toxicity testing are to obtain information on the biologic activity of a chemical and gain insight into its mechanism of action. The information on acute systemic toxicity generated by the test is used in hazard identification and risk management in the context of production, handling, and use of chemicals. The LD50 value, defined as the statistically derived dose that, wh...

Sub Acute Toxicity of Aceclofenac Drug in Albino Rat

Introduction: Nonsteroidal anti-inflammatory drugs are the most commonly used drugs to reduce pain and inflammation. Aceclofenac is a newer derivative of diclofenac with less gastrointestinal complications. The objective of the present study was to evaluate the toxicity profile of sustain release aceclofenac injection in rats at three dose levels, ranging from 2 to 10 mg/kg body weight. Mater...

Acute and sub-acute oral toxicity of ethanol extract of Cassia fistula fruit in male rats

Objective: The plantCassia fistula L. (Caesalpiniaceae) is traditionally used to treat heart diseases, abdominal pain and fever. The present study was aimed to investigate the toxic effects acute and sub-acute administration of ethanol extract of C. fistula fruit (CFE) in male Wistar rats. Materials and Methods: In acute toxicity, the effects of a single oral dose (1000, 3000 and 5000 mg/kg) of...
