      Methotrexate (MTX) is a widely used anticancer and antirheumatic drug that has been postulated to protect against metabolic risk factors associated with type 2 diabetes, although the mechanism remains unknown. MTX inhibits 5-aminoimidazolecarboxamide ribonucleotide formyltransferase/inosine monophosphate cyclohydrolase (ATIC) and thereby slows the metabolism Cited by: So the last post introduced modification of foreign substances by Phase 1 metabolism using various enzymes (CYP enzyme being very important) and different types of reaction mechanisms (oxidation, reduction, hydrolysis etc.) to increase the polarity/water solubility of the xenobiotic in preparation for excretion or often to increase the likelihood of further modification through Phase 2 metabolism.

    In one study, methotrexate clearance reductions were 35%, 40%, and 66% with penicillin, ticarcillin, and piperacillin, respectively. Serious adverse effects, primarily hematologic, have been described with . Full text of "A Bibliography of imported fire ants and the chemicals and methods used for their control" See other formats.

Methoxychlor is an insecticide whose metabolite displays both estrogenic and anti-androgenic activity in vitro and in vivo. If treatment is administered at weaning, methoxychlor will induce a number of effects.

Methoxychlor (MXC) is used worldwide against insects and other pests. This organochlorine pesticide acts as a xenoestrogen, promotes oxidative stress, and is considered Cited by: 3. @article{osti_, title = {Methoxychlor causes mitochondrial dysfunction and oxidative damage in the mouse ovary}, author = {Gupta, R K and Schuh, R A and Department of Anesthesiology, University of Maryland, Baltimore, MD and Fiskum, G and Department of Anesthesiology, University of Maryland, Baltimore, MD and Flaws, J A}, abstractNote = {Methoxychlor.

antiinflammatory effects of methotrexate by high-dose fo-linic acid likely results from decreased methotrexate uptake, since folinic acid and methotrexate compete for the same transporter (RFC1) for absorption from the gastrointestinal tract and for cellular uptake Cited by: Methoxychlor is a manufactured chemical that does not occur naturally in the environment.

Review of the scientific evidence linking occupational and environmental pesticide exposure to endocrine disruption health effects 2,4-D No reduction in like effects of methoxychlor caused Author: Pierluigi Cocco.

Rats fed from very low to high doses of methoxychlor (10 to 2, mg/kg) for two years had growth retardation above ppm but no tissue damage from the methoxychlor. Human volunteers taking oral doses of to mg/kg/day for six weeks had no adverse effects.

This was a study concerning effects, uptake, and metabolism of mirex, methoxychior, and 2,4—D in the seaweeds Ulva sp., Enteromorpha sp. and Rhodymenia sp.
