Takahashi, Yasuo published the artcileConcentrations of surfactant-derived impure and degradation compounds in river waters and water supplies, Name: 2-(4-(tert-Butyl)phenoxy)acetic acid, the publication is Kankyo Kagaku (2004), 14(4), 845-853, database is CAplus.

The concentrations of surfactant-derived impure and degradation compounds in water samples from the TE river differ among water sampling station. The concentration was about 0.01-0.20 ¦Ìg/L for alkylbenzene, from under quantification limit to ?0.010 ¦Ìg/L for 4-t-butylphenol, about 0.005-0.050 ¦Ìg/L for 4-t-octylphenol, from under quantification limit to ?0.50 ¦Ìg/L for nonylphenol, from under quantification limit to ?0.10 ¦Ìg/L for nonylphenol monoethoxylate, from under quantification limit to ?0.02 ¦Ìg/L for 4-t-butylphenoxy acetic acid, and 0.02-0.07 ¦Ìg/L for 4-t-octylphenoxy acetic acid; chlorides and n-type alkylphenols were not detected. In the TE river water, the anion surfactant concentration was estimated to be higher ?2000 times than alkylbenzene concentration, and the nonionic surfactant concentration to be higher ?200 times than the total concentration of nonylphenol and 4-t-octylphenol. No impure and degradation compounds derived from surfactants were detected in the water supplies. This is because these compounds react with Cl, forming byproducts.

Adhikari, Birendra Babu published the artcileAllosteric effect of the first lead ion on stepwise extraction of the second lead ion with p-t-butylcalix[5]arene pentacarboxylic acid derivative, COA of Formula: C12H16O3, the publication is Tetrahedron Letters (2010), 51(27), 3481-3485, database is CAplus.

A calix[5]arene-based solvent extraction reagent displaying very high selectivity for lead has been prepared, one mol. of which extracts two lead ions in a stepwise manner. The first Pb²⁺ ion is bound to five phenoxy oxygen atoms inside the calixarene cavity due to which the ligand undergoes conformational freezing in stable cone conformer. This causes pos. allosteric effect for co-extraction of the second lead ion due to the aggregation of functional groups.

Kamata, Ryo published the artcileAgonistic effects of diverse xenobiotics on the constitutive androstane receptor as detected in a recombinant yeast-cell assay, Application In Synthesis of 1798-04-5, the publication is Toxicology In Vitro (2018), 335-349, database is CAplus and MEDLINE.

The constitutive androstane receptor (CAR) is a nuclear receptor and transcription factor regulating proteins involved in xenobiotic metabolism Agonist activation of the CAR can trigger metabolic activation and toxification as well as detoxification and clearance; accordingly, xenobiotic substances acting as CAR ligands may pose a threat to human and animal health. The authors used yeast cells transduced with the human CAR and the response pathway to measure the CAR-agonistic activities of 549 synthetic or natural compounds: 216 of the tested compounds exhibited CAR-agonistic effects. Eighty-four percent of CAR-activating compounds were aromatic compounds, and >65% of these active compounds were aromatic hydrocarbons, bisphenols, monoalkyl phenols, phthalates, styrene dimers, di-Ph ethers, organochlorines, and organophosphates. The ten most potent compounds were 4-tert-octylphenol (4tOP; reference substance), 4-nonylphenol, diethylstilbestrol, benzyl Bu phthalate, 2-(4-hydroxyphenyl)-2,4,4-trimethylchroman, o,p’-DDT, methoxychlor, di-Pr phthalate, hexestrol, and octachlorostyrene. The activities of these nine non-reference compounds exceeded 10% of the 4tOP activity. Anal. of para-monoalkyl phenols suggests that branching of the alkyl group and chlorination at the ortho position raises potency. This study provides critical information for identifying the potential of CAR-mediated toxic hazards and for understanding the relevant mechanism.

Sarges, Reinhard published the artcileGlucose transport-enhancing and hypoglycemic activity of 2-methyl-2-phenoxy-3-phenylpropanoic acids, Recommanded Product: 2-(4-(tert-Butyl)phenoxy)acetic acid, the publication is Journal of Medicinal Chemistry (1996), 39(24), 4783-4803, database is CAplus and MEDLINE.

A series of 2-phenoxy-3-phenylpropanoic acids has been prepared which contains many potent hypoglycemic agents as demonstrated by assessing glucose lowering in ob/ob mice. Some compounds normalize plasma glucose in this diabetic model at doses of approx. 1 mg/kg. The mechanism of action of these drugs may involve enhanced glucose transport, especially in fat cells, but the compounds do not stimulate GLUT4 translocation and do not increase the levels of GLUT1 or GLUT4 in vivo. Thus, these compounds may enhance the intrinsic activity of the glucose transporter GLUT1 or GLUT4. Some compounds also modestly decrease hepatocyte gluconeogenesis in vitro, but this is not likely to be a major contributor to the hypoglycemic effect observed in vivo. Likewise, a modest decrease in food consumption observed with some of these compounds was shown by a pair-feeding experiment not to be the primary cause of the hypoglycemia observed

Complexation behavior of a plural ion-exchangeable p-t-butylcalix[5]arene pentacarboxylic acid derivative towards trivalent In was studied along with its monomeric analog from weakly acidic media into CHCl₃. The cyclic structure of calixarene ligand providing certain cavity and cooperativity of functional groups significantly affect the complexation behavior and the calixarene derivative is an excellent extractant over monomeric analog. The extraction mechanism is ion exchange and carboxylic acid groups are adequate functional sites for extraction Mononuclear and/or polynuclear species of In and monomeric or bridged dimeric species of calixarene are involved in complexation and the composition of extracted complex varied with solution pH.

A calix[5]arene based solvent extraction reagent 3, appending carboxylic acid groups at the lower rim, has been developed and its complexation behavior towards some transition metal ions has been studied. The host 3 can selectively and quant. extract Pb(2+) ions above pH 1.8 while other divalent ions such as Cu(2+), Zn(2+), Co(2+), Ni(2+) are extracted quant. only above pH 3.0. The outstanding Pb(2+) selectivity of 3 comes from the size fit complementarity effect of the Pb(2+) ion in the calix[5]arene cavity. One mol. of 3 extracts two Pb(2+) ions in a stepwise manner. The first Pb(2+) ion is extracted into the deep cavity of the calix[5]arene defined by phenoxy oxygen atoms. The first complexed Pb(2+) ion acts as a template to bring the host into a cone conformation and induces a pos. allosteric effect for the extraction of the second Pb(2+) ion at an oxygen rich coordinating site composed of carboxyl groups. Both the Pb(2+) ions are extracted through an ion exchange mechanism and the electroneutral complex in the organic phase is formed by the release of an equivalent number of hydrogen ions into aqueous solution The loaded Pb(2+) is easily back-extracted from Pb(2+)-complexed 3 using dilute acid solution

The solvent extraction behavior of multiple proton ionizable p-tert-butylcalix[4]arene and [6]arene carboxylic acid derivatives towards indium was studied along with an acyclic monomeric analog from weakly acidic media into chloroform. The extraction mechanism is ion exchange and carboxylic acid groups are adequate ligating sites for extraction The cyclic structure of calixarene ligands to accommodate the potential guest species and the cooperativity effect of multifunctional groups significantly affect the complexation behavior and calixarene derivatives are excellent extractants over the monomeric analog. The composition of the extracted complex depends on the solution pH and attempts to determine the composition of the extracted complex for the extraction of indium were stymied by complications arising from the formation of polynuclear species of indium and bridged polymeric species of calixarene carboxylic acid derivatives One mole of calix[4]arene derivative extracts 2.5 mol of indium whereas the calix[6]arene derivative tends to extract 4.0 mol of indium. The loaded indium is back extracted with 1 mol dm^-3 hydrochloric acid solution Though quant. back extraction of indium was achieved from the fully loaded calix[6]arene derivative, it was only achieved up to 85% in the case of the calix[4]arene derivative

Studies on extraction equilibrium constants at different temperatures and thermodn. parameters of solvent extraction of Pb²⁺ ion with carboxylic acid derivatives of different ring size calixarenes and structure related monomeric compound have been carried out. The extraction equilibrium constants corresponding to calix[n]arene (n = 4, 5, 6) derivatives decrease in the order [5]arene > [6]arene > [4]arene. In all cases, the complexation process is primarily enthalpy driven. The favorable enthalpic contribution for extraction of Pb²⁺ is in the order hexamer ¡Ö monomer > tetramer > pentamer. However, the unfavorable entropic loss follows the order: monomer > hexamer > tetramer > pentamer. Overall stability of the host-guest complex is the function of entropy-enthalpy compensation and the free energy of complexation is min. for the pentamer, followed by tetramer ¡Ö hexamer and monomer. Although the carboxylic acid derivative of calix[4]arene is more preorganized than the calix[5]arene derivative, extraction of Pb²⁺ ion with the tetramer passes through greater entropic loss than that with the pentamer and the degree of preorganization of calix[4]arene derivative is far from perfect for the complexation and extraction of Pb²⁺ ion. As compared to tetrameric and hexameric counterparts, the structural features of the carboxylic acid derivative of calix[5]arene prior to complexation contribute much to interact with the Pb²⁺ ion and form a thermodynamically stable complex.

Wang, Yanliang published the artcileEffective removal of calcium and magnesium sulfates from wastewater in the rare earth industry, Formula: C12H16O3, the publication is RSC Advances (2019), 9(58), 33922-33930, database is CAplus and MEDLINE.

The wastewater discharged from the rare earth (RE) industry generally contains a high level of calcium and magnesium sulfates, which confers permanent hardness and causes difficulties in recycling this wastewater. In this study, the alkyl phenoxy acetic acid derivatives including 4-Me phenoxy acetic acid (M-POAA), 4-tert-Bu phenoxy acetic acid (B-POAA) and 4-tert-octyl phenoxy acetic acid (O-POAA), were synthesized via the Williamson reaction and characterized by NMR (NMR), IR (IR), and ultra-violet (UV) spectroscopy, as well as elemental anal. and X-ray diffraction (XRD). Synthesis of the POAAs were simple and green, and the raw materials used for their production are widely available and low-cost. The potential for removal of Ca and Mg sulfates from industrial wastewater using POAAs as the organic precipitants was assessed. The total precipitation efficiencies of Ca and Mg from wastewater with the use of POAAs increased with the following order: M-POAA < B-POAA < O-POAA. The residual concentrations of Ca and Mg using O-POAA as the precipitant were lower than 0.099 and 0.089 g L^-1, resp. The O-POAA could be regenerated five times without any significant change in its structure and precipitation performance. Thus, the use of the novel precipitants is a prospective alternative to the conventional processes for softening wastewater.
