Dioctyl phthalate
Based on 2 publication(s) in Google Scholar
Dioctyl phthalate (DNOP) is a plasticizer. Dioctyl phthalate increases the activities of alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in the liver, as well as the levels of creatinine and urea in the kidney. Exposure to Dioctyl phthalate disrupts the homeostasis of the intestinal microbial community, increases the abundance of pathogenic bacteria, and reduces the abundance of beneficial bacteria such as Lactobacillus. Dioctyl phthalate induces significant and dose-dependent inflammatory responses in the liver, spleen and kidney of mice.

Biological Activity
Dioctyl phthalate (50-500 mg/kg⋅bw; oral gavage; daily; 12 weeks) induces multi-organ damage (liver, spleen, kidney, ileum) and gut microbiota dysbiosis in aged C57BL/6J male mice, with high-dose exposure causing significant weight loss (P < 0.05), increased liver-to-body weight ratio (P < 0.001), elevated hepatic ALT (P < 0.01) and ALP (P < 0.05) levels, increased splenic weight (P < 0.01), elevated renal creatinine (P < 0.05) levels, and reduced Firmicutes/Bacteroidetes ratio in low-dose mice (P < 0.05).
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Significantly elevated creatinine (P < 0.05) levels in high-dose group compared to controls; significantly elevated urea levels (P < 0.05) in both dose groups compared to controls.
Significantly increased serum diamine oxidase (DAO) and D-lactic acid levels in both dose groups compared to controls (P < 0.05).
Decreased Firmicutes relative abundance (50.9% in controls, 44.3% in low-dose, 39% in high-dose) and increased Bacteroidetes abundance (24.8% in controls, 35.9% in low-dose, 38.4% in high-dose) with increasing dose.
Significantly decreased Firmicutes/Bacteroidetes ratio in high-dose group compared to controls (P < 0.05).
