Dihexyl phthalate
Based on 1 publication(s) in Google Scholar
Dihexyl phthalate is an orally active phthalate ester (PAEs) widely used as a plasticizer, and it acts as an environmental endocrine disruptor. Dihexyl phthalate exhibits endocrine-disrupting and reproductive toxic properties, induces oxidative stress and inflammation, and ultimately causes apoptosis and damage to reproductive organs such as the testes. Dihexyl phthalate can be used in studies related to developmental toxicity, embryonic lethality, teratogenicity, and abnormal development of the male reproductive system.

Biological Activity
Description
In Vitro
Dihexyl phthalate (100 μg/mL; 10 min at 37°C) inhibits phenoloxidase activity in hemocytes of Macrobrachium rosenbergii and reduces the production of superoxide anions in hemocytes[3].
Dihexyl phthalate (100 μg/mL; ≥10 min) induces time-dependent morphological changes and apoptosis in hemocytes of Macrobrachium rosenbergii[3].
Dihexyl phthalate (1-10 μg/L; 6-24 h) promotes biofilm formation, increases biomass, and enhances resistance to sodium hypochlorite disinfectant in Pseudomonas aeruginosa biofilms; it upregulates the expression of quorum sensing-related genes, bacterial adhesion genes, EPS secretion genes, and antioxidant system genes; significantly increases the production of polysaccharides, extracellular DNA, and proteins; and increases biofilm density, elevates the live/dead cell ratio, as well as increases elastic modulus and surface roughness[4].
Dihexyl phthalate (1-10 μg/L; 3 h) increases intracellular reactive oxygen species (ROS) levels in planktonic Pseudomonas aeruginosa[4].
Dihexyl phthalate (1-10 μg/L) increases cellular ATP activity, enhances the activities of superoxide dismutase and catalase, elevates glutathione concentration, and reduces the overall reactive oxygen species (ROS) level in Pseudomonas aeruginosa biofilms[4].
Dihexyl phthalate (100 μg/mL; 10 min) inhibits adhesion and pseudopodium formation of hemocytes from Macrobrachium rosenbergii, reducing the proportion of adherent cells to 85.0% of that in the control group and the proportion of pseudopodium-forming cells to 17.6% of that in the control group[3].

Cell Line:Pseudomonas aeruginosa PAO1
-
Concentration:1, 2, 5, 10 μg/L
-
Incubation Time:6 h
-
Result:Significantly upregulated the expression of genes associated with quorum sensing secretion (lasI, lasR, rhlI, rhlR), bacterial adherence (sagS), EPS excretion (pslA, pelA), and the antioxidative system (sodM, msrB).

Animal Model:Sprague-Dawley (female primiparous, 180-200 g, pregnant exposed during gestational days 6-20)[2]
-
Dosage:250 mg/kg; 500 mg/kg; 750 mg/kg
-
Administration:p.o.; once daily; gestational days 6-20
-
Result:Caused maternal toxicity at 750 mg/kg/day, evidenced by significant reductions in maternal food consumption and body weight gain.
Caused a slight but significant increase in liver weight and induced cyanide-insensitive palmitoyl-CoA oxidation activity (a peroxisomal enzyme marker).
Caused a high incidence of post-implantation loss (severe embryolethality) at 750 mg/kg/day.
Caused a significant decrease in fetal body weight and induced external, visceral, and skeletal malformations (mainly including cleft palate, eye defects, and axial skeleton abnormalities) at 500 and 750 mg/kg/day.
Caused a dose-related, significant reduction in the anogenital distance (AGD) of male fetuses at all doses (250, 500, 750 mg/kg/day).
Increased the incidence of undescended testes in male fetuses at 500 and 750 mg/kg/day.
