17-DMAG is a hydrophilic derivative of the molecular chaperone inhibitor 17-(allylamino)-17-demethoxygeldanamycin (17-AAG; NSC-330507), which is currently being evaluated for the treatment of cancer in clinical trials. 17-DMAG offers a potential advantage over 17-AAG because its aqueous solubility eliminates the need for complicated formulations that are(More)
Drugs derived from amphetamine, methamphetamine and their methylenedioxy- analogues, although being sold as plant food or bath salts, are being used as legal alternatives to scheduled amphetamine stimulants. These products often contain methylone, mephedrone and methylenedioxypyrovalerone (MDPV)--three amphetamine derivatives shown to have strong(More)
Resveratrol, (3,5,4'-trihydoxystilbene) a compound found in grapes, mulberries, and peanuts, has antimycotic, antiviral, and beneficial cardiovascular and cancer preventive activities. It is being developed for several clinical indications. To evaluate the potential toxicity of resveratrol, rats were administered by gavage 0, 300, 1000, and 3000 mg(More)
A death involving abuse of propylhexedrine and mitragynine is reported. Propylhexedrine is a potent α-adrenergic sympathomimetic amine found in nasal decongestant inhalers. The decedent was found dead in his living quarters with no signs of physical trauma. Analysis of his computer showed information on kratom, a plant that contains mitragynine, which(More)
Several artemisinin (qinghaosu) derivatives have been developed and are in use as antimalarial drugs but scant animal or human toxicity data are available. We noted a progressive syndrome of clinical neurological defects with cardio-respiratory collapse and death in 5/6 dogs dosed daily for 8 d with intramuscular arteether (AE) at 20 mg/kg/d in a(More)
Cathinone derivatives (bath salts) have emerged as the latest drugs of abuse. 3,4-methylenedioxypyrovalerone (MDPV) is the primary active ingredient in bath salts used in this country. This article presents the second reported cause of death by MDPV intoxication alone. In April 2011, a delusional man was emergently brought to a hospital, where he(More)
Resveratrol, a polyphenolic compound found in grape skin and peanuts has been shown to prevent many diseases including cardiovascular diseases and cancer. To better understand resveratrol's potential in vivo toxicity, we studied the dose response using cDNA stress arrays coupled with drug metabolizing enzymatic (DME) assays to investigate the expression of(More)
An accidental death caused by the combined use of a new designer drug, 4-methylmethcathinone (mephedrone), and heroin is reported. A 22-year-old Caucasian male was found unresponsive in his living quarters and was transported to the hospital where he died. During autopsy, needle marks were found along the decedent's lower legs and ankles. Investigators(More)
Based on its ability to chelate copper, TTM is being studied as an antiangiogenic agent for cancer therapy. The purpose of this study was to evaluate the toxicity of TTM and the protection of copper supplementation on the reproductive capability of male and female CD rats. Doses of 0, 1, 4, and 12 mg/kg/day with copper supplementation (110 mg/kg of diet)(More)
The potential toxic interactions in F344 rats of the munitions compounds trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) were examined following their coadministration in the diet. Groups of 10 rats per sex received TNT at doses of 5 or 125 mg/kg/day, RDX at doses of 30, 100, or 300 mg/kg/day, and combinations thereof for 13 weeks.(More)
