Toxicity

ExcerptReferenceRelevance
" Lethality studies in female Balb-c mice resulted in an LD10 value of 20 mg/kg (95% confidence limits; range, 19-21 mg/kg) and an LD50 value of 22 mg/kg (95% confidence limits; range, 21-23 mg/kg)."( The pharmacokinetics and toxicity of the anthrapyrazole anti-cancer drug CI-941 in the mouse: a guide for rational dose escalation in patients.

Pharmacokinetics

ExcerptReferenceRelevance
" More recently, the use of preclinical pharmacokinetic information in mice has been proposed to also provide information that might expedite early clinical trials and more specifically phase I studies."( Phase I trial of the anthrapyrazole CI-941: prospective evaluation of a pharmacokinetically guided dose-escalation.
