Two cathepsin B inhibitors were isolated from the culture supernatant of a marine Pseudomonas sp. PB01 (GenBank Accession No. EU126129). Their structures were elucidated by spectroscopic analyses as dibutyl phthalate and di-(2-ethylhexyl) phthalate. Both dibutyl phthalate and di-(2-ethylhexyl) phthalate showed dose-dependent cathepsin B inhibitions with IC(50) of 0.42 and 0.38 mM, respectively....

The industry under consideration uses chiefly the phthalate plasticizers: predominantly dibutyl phthalate (DBP) and higher alkyl phthalates (DAP-789); periodically dioctyl phthalate (DOP), diisooctyl phthalate (DIOP), and benzyl butyl phthalate (BBP). Some formulations contain small amounts of one of the sebacates (dibutyl sebacate, DBS, or dioctyl sebacate, DOS) or adipates (dibutyl adipate, D...

A cold-active phthalate esters hydrolase gene (designated dphB) was identified through functional screening of a metagenomic library derived from biofilms of a wastewater treatment plant. The enzyme specifically catalyzed the hydrolysis of dipropyl phthalate, dibutyl phthalate, and dipentyl phthalate to the corresponding monoalkyl phthalate esters at low temperatures. The catalytic triad residu...

Using a novel and highly selective technique, we measured monoester metabolites of seven commonly used phthalates in urine samples from a reference population of 289 adult humans. This analytical approach allowed us to directly measure the individual phthalate metabolites responsible for the animal reproductive and developmental toxicity while avoiding contamination from the ubiquitous parent c...

New solid polymer electrolytes (SPE) based on poly(ethylene oxide) (PEO) doped with lithium trifluoromethanesulfonate (LiCF3SO3), dibutyl phthalate (DBP) plasticizer, and zirconium oxide (ZrO2) nanoparticles were prepared by solution-casting technique. The conductivity was enhanced by addition of dibutyl phthalate (DBP) plasticizer and ZrO2 nanofiller with maximum conductivity (1.38 × 10(-4) Sc...

Bacteria of the genus Methylobacillus are methanotrophs, a metabolic feature that is widespread in the phylum Proteobacteria. The study demonstrates the isolation and characterization of a newly isolated Methylobacillus sp. V29b. which grows on methanol, protocatechuate, monobutyl phthalate, dibutyl phthalate, diethyl phthalate, benzyl butyl phthalate, dioctyl phthalate and diisodecyl phthalate...

Due to public health concerns, the Chinese government and the US Consumer Product Safety Commission (CPSC) both introduced test methods for the analysis of phthalate content in childcare items and toys using GC/MS in 2008. These regulatory methods require determination of the presence of six regulated phthalate esters including dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), bis(2-ethylh...

In the title compound, 2C(3)H(5)N(2) (+)·C(8)H(4)O(4) (2-)·H(2)O, the cations, anion and water mol-ecule are connected by N-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional network.

In this study, molecularly imprinted polymers were synthesized for dibutyl phthalate as a bioactive chemical compound with antifungal activity which produced by Trichoderma Harzianum (JX1738521). The molecularly imprinted polymers were synthesized via precipitation polymerization method from methacrylic acid, dibutyl phthalate and trimetylolpropantrimethacrylate as a functional monomer, templat...
