Optical Activity ( + / - )

Dimethenamid is a widely used herbicidal compound. It was originally developed by Sandoz Agro and previously marketed as a racemic mixture. It is now known that only the S-isomer exhibits herbicidal activity. The S-isomer is known by the common name dimethenamid-P. Human and animal toxicity are considered low enough for commercial use as a herbicide.

Curator's Comment: referenced study was conducted in rat
Acute toxicity studies conducted in rats determined LD50's for Racemic dimethenamid as 371 mg/kg bw and 427 mg/kg bw for male and female rats respectively. Acute Toxicity of dimethenamid-P was determined in rats with a male LD50 of 429 mg/kg bw and female LD50 of 531 mg/kg bw.
Route of Administration: Oral
Germ cell mutagenicity and genotoxicity were evaluated using bacterial and mammalian cell mutagenicity tests, chromosome damage tests, and unscheduled DNA synthesis tests. These studies conclude that neither dimethenamid nor dimethenamid-P possesses genotoxic potential.
