Application

Plasticizer

General description

Dibutyl phthalate (DBP) is most commonly used as a plasticizer in a variety of household products. It has the ability to leach and evaporate into the environment while using or disposing of these products. Therefore, studies are being conducted to assess its toxic and apoptotic effects. Studies have also indicated that exposure to high doses of DBP may interfere with progesterone and estradiol production.

Dibutyl phthalate impairs steroidogenesis and a subset of LH-dependent genes in cultured human mural granulosa cell in vitro.
Adir M
Reproductive Toxicology, 69, 13-18 (2017)
Dibutyl phthalate (DBP)-induced apoptosis and neurotoxicity are mediated via the aryl hydrocarbon receptor (AhR) but not by estrogen receptor alpha (ER?), estrogen receptor beta (ER?), or peroxisome proliferator-activated receptor gamma (PPAR?) in mouse cortical neurons.

Xenobiotic exposure during pregnancy and lactation has been linked to perinatal changes in male reproductive outcomes and other endocrine parameters. This pilot study wished to assess whether brief maternal exposure of rats to xenobiotics dibutyl phthalate (DBP) or diethylstilbestrol (DES)

Immunometabolism, 2(4), e200029-e200029 (2020-09-04)
Assays to monitor the metabolic state or nutrient uptake capacity of immune cells at a single cell level are increasingly in demand. One assay, used by many immunologists, employs 2-(N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)Amino)-2-Deoxyglucose (2-NBDG), a fluorescent analogue of 2-deoxyglucose (2DG), as a substrate
Harpreet Bhatia et al.
Aquatic toxicology (Amsterdam, Netherlands), 149, 103-115 (2014-03-01)
Phthalic acid esters (PAEs) are a class of synthetic industrial chemicals commonly found in the aquatic environment worldwide. PAEs have been recognised as anti-androgens in male mammals but little is known about their endocrine disrupting effects in fish. This study
