Some studies indicate that Black women have higher exposure to multiple non-persistent endocrine disrupting chems. (EDCs) than white women, but little is known about correlates of exposure to EDC mixtures Using baseline data from a prospective cohort study of reproductive-aged Black women (N = 751), we characterized profiles of EDC mixtures and identified correlates of exposure. At baseline, we quantified biomarkers of 16 phthalates, 7 phenols, 4 parabens, and triclocarban in urine and collected covariate data through self-administered questionnaires and interviews. We used principal component (PC) anal. and k-means clustering to describe EDC mixture profiles. Associations between correlates and PCs were estimated as the mean difference (β) in PC scores, while associations between correlates and cluster membership were estimated as the odds ratio (OR) of cluster membership. Personal care product use was consistently associated with profiles of higher biomarker concentrations of non-persistent EDCs. Use of nail polish, menstrual and vaginal products (e.g., vaginal powder, vaginal deodorant), and sunscreen was associated with a mixture of phthalate and some phenol biomarkers using both methods. Current vaginal ring use, a form of hormonal contraception placed inside the vagina, was strongly associated with higher concentrations of high mol. weight phthalate biomarkers (k-means clustering: OR = 2.42, 95% CI = 1.28, 4.59; PCA: β = -0.32, 95% CI = -0.71, 0.07). Several dietary, reproductive, and demog. correlates were also associated with mixtures of EDC biomarkers. These findings suggest that personal care product use, diet, and contraceptive use may be sources of exposure to multiple non-persistent EDCs among reproductive-aged Black women. Targeted interventions to reduce exposure to multiple EDCs among Black women are warranted.

Ganda, Sylvia published the artcileCorona-Loading Strategies for Crystalline Particles Made by Living Crystallization-Driven Self-Assembly, COA of Formula: C12H20O6, the publication is Macromolecules (Washington, DC, United States) (2021), 54(14), 6662-6669, database is CAplus.

Self-assembled block copolymer (BCP) nanoparticles offer exciting opportunities for drug delivery applications. A key feature of using BCP nanoparticles for drug delivery is their ability to accommodate therapeutic cargoes within their particle core. This has become widely established for BCP nanoparticles with an amorphous core. The same, however, cannot be achieved with BCP nanoparticles with a crystalline core. This is because the encapsulation of therapeutic cargoes in a crystalline particle core disrupts crystallinity and ultimately leads to particle disassembly. Herein, we present several strategies to incorporate therapeutics and other functional cargoes onto the surface of crystalline particles, as this helps to ensure that the crystallinity of the particle core is maintained and the particle morphol. is hence unaffected. As a platform to showcase our strategies, in this study, we used biodegradable and bioactive 2D glycoplatelets prepared by living crystallization-driven self-assembly (CDSA). Specifically, we show that we can incorporate either an anticancer drug, doxorubicin (DOX), or a fluorescent dye, Cyanine5 (Cy5), onto the surface of glycoplatelets by seeded growth of prefunctionalized polymers or via postmodification using polymers with reactive handles. We believe that the strategies presented herein are versatile and should thus be applicable to other CDSA systems. Overall, our findings present new opportunities for crystalline particles to be used in drug delivery application.

The triplet excited state of the 9-phenylxanthenium cation is observed directly by both luminescence and transient absorption techniques. The triplet-triplet absorption shows λ_max ≤ 300 nm and decays over a period of several microseconds in the absence of easily oxidized donors. The triplet cation reacts with 9-phenylxanthydrol and biphenyl via electron transfer to give the corresponding radical and radical cation and also reacts rapidly with both oxygen and 1,3-cyclohexadiene.

The alc. 9-phenylxanthen-9-ol (I) was adsorbed on silica gel and alumina surfaces. Under room temperature conditions the 9-phenylxanthenyl cation (II) was formed and stabilized on silica gel. Steady state fluorescence studies show II fluoresces with λ_max = 210 nm and that this luminescence occurs via both direct excitation of II as well as adiabatic dehydroxylation of the excited singlet of I. Time-resolved experiments show II has a fluorescence lifetime on silica gel of 37 ± 2 ns and is quenched by oxygen at a rate of 1.5 × 10⁴ torr^-1 s^-1.

Synthesizing chems. and materials from renewable sources is one of the main aims of modern science. Carbohydrates represent excellent renewable natural raw materials that are ecofriendly, inexpensive, and biol. compatible. A green procedure has been developed for the vinylation of carbohydrates by using readily available calcium carbide. Various carbohydrates were utilized as starting materials, resulting in mono-, di-, and tetravinyl ethers in high to excellent yields (81-92 %). The synthesized biobased vinyl ethers were utilized as monomers in free radical and cationic polymerizations A unique combination of a smooth surface and intrinsic microcompartments was achieved in the synthesized materials. Two types of biobased materials were prepared involving microspheres and intrinsic hollow compartments in polymers. SEM with built-in ion beam cutting was applied to reveal the spatial hierarchical structures in 3D space.

Conant, J. B. published the artcileSuperacid solutions. IV. Determination of the strength of weak bases and pseudo bases in glacial acetic acid solution, Recommanded Product: 9-Phenyl-9H-xanthen-9-ol, the publication is Journal of the American Chemical Society (1930), 4436-50, database is CAplus.

cf. C. A. 22, 4035. A spectrophotometric study has been made of the acid-base equilibrium in solutions of crystal violet in buffered glacial AcOH solutions The extinction coefficient was measured at intervals of 10 mμ from 470 to 680. Data are given for the fundamentals chosen for the violet, green and yellow forms; also for the dissociation constants of crystal violet from spectrophotometric data at 25° in urea-H₂SO₄, urea-HClO₄ and acetoxime-H₂SO₄ buffers. The change of pK’₁ for crystal violet with change in ionic strength is shown in the form of curves; this effect is very marked; the total change of pK’₁ from the limiting value at μ = 0 to √μ = 0.5 is about 2.6 p_H units. In the more concentrated solutions there are sp. effects depending on the nature of the neutral salt. These effects are larger than the corresponding effects in H₂O because of the low dielec. constants of AcOH; the natures of both the cation and anion of the neutral salt are important. An electrometric study of weak bases and pseudo bases in glacial AcOH reveals the large effect of changing ionic strength, also noted in the spectrophotometric study. The following apparent pK’ values for pseudo bases at 25° in glacial AcOH are reported (bases in 0.05 M solution titrated with H₂SO₄ μ = 0.2 with Me₃NHSO₃C₆H₄Ne-p): Ph₃COH -1.47; C₁₀H₇CPh₂OH -1.25; (MeOC₆H₄)₂CHOH -1.14; MeOC₆H₄CPh₂OH -0.59; phenylxanthanol 1.91; dinaphthoxanthanol. 2.40 MeOC₆H₄)₃COH, 2.56. The effect of added H₂O on the apparent constants of a number of weak pseudo bases is reported. A method is outlined for obtaining significant values for the relative basicity of the “halochromic carbinols.”

Spichal, Lukas published the artcileThe purine derivative PI-55 blocks cytokinin action via receptor inhibition, Synthetic Route of 1122579-42-3, the publication is FEBS Journal (2009), 276(1), 244-253, database is CAplus and MEDLINE.

One of several potential approaches to study mechanisms of action of biol. active compounds is to develop their agonists and antagonists. In the present study, we report the identification of the first known mol. antagonizing the activity of the plant hormone cytokinin at the receptor level. This compound, 6-(2-hydroxy-3-methylbenzylamino)purine, designated PI-55 in the present study, is structurally closely related to cytokinin 6-benzylaminopyrine, but substitutions at specific positions of the aromatic side chain strongly diminished its cytokinin activity and conferred antagonistic properties. PI-55 competitively inhibited the binding of the natural ligand trans-zeatin to the Arabidopsis cytokinin receptors cytokinin response 1 (CRE1)/Arabidopsis histidine kinase (AHK) 4 and AHK3 and repressed induction of the cytokinin response gene ARR5:GUS. Genetic anal. revealed that CRE1/AHK4 is the primary target of PI-55. Cytokinin bioassays also demonstrated the anticytokinin effect of PI-55 in several other species. Furthermore, we show that PI-55 accelerated the germination of Arabidopsis seeds and promoted the root growth and formation of lateral roots, thus phenocopying the known consequences of a lowered cytokinin status and demonstrating its potential to inhibit cytokinin perception in planta. PI-55 is the first example for the targeted development of a cytokinin antagonist and represents an initial step for the preparation of cytokinin antagonists with broad activity and reduced agonistic properties.

Owczarek, Katarzyna published the artcileValidated GC-MS method for determination of bisphenol a and its five analogues in dietary and nutritional supplements, SDS of cas: 80-09-1, the publication is Microchemical Journal (2022), 107643, database is CAplus.

Bisphenol A (BPA) and its analogs showing structural and functional similarity to BPA are commonly applied in various industrial applications and thus are becoming ubiquitous in the environment. At the same time there is increasing scientific evidence that exposure to these chems. may lead to adverse health effects in human and wildlife. In recent years dietary and nutritional supplements dedicated for athletes have become more popular and are widely used even by people who are not professionals. This study presents the development, optimization and validation of an anal. procedure for determination of six bisphenol analogs in dietary supplements using gas chromatog. – mass spectrometry technique. All validation parameters met the established acceptance criteria in accordance with international guidelines. The method was linear within the tested range of 50-1000 ng/mL, the limit of quantitation was set as the lowest calibration point 50 ng/mL, detection limit for each bisphenol was calculated as standard estimation error on the basis of the linearity testing and was in the range of 8.73-15.44 ng/mL. Method trueness, accuracy (within and between runs) and precision were also verified and were in the range of 78.8 – 100.4%, 94.3 – 103.1%,0.5 – 9.6% resp. The developed procedure was successfully applied for real samples anal., namely for fifteen sport supplements of different composition and designated for various purposes, i.e. for increasing effectiveness, promoting muscle recovery and endurance, reducing tiredness and fatigue or increasing immune ability. For the majority of samples, bisphenols were either not detected or detected at the LOD level except bisphenol A which was quantitated in few samples at LOQ level or higher (in the range 0.852-2.892 ng/mg). The field of bisphenol analogs analytics has increased in recent years due to law regulations becoming more strict, thus the development of new anal. tools for quality control of dietary products is needed and fully justified.

Liu, Qian published the artcileThree-dimensional (3D) thermal controlled polymer for simplified dispersive liquid-liquid microextraction in phthalic acid easters detection of straw, Category: alcohols-buliding-blocks, the publication is Microchemical Journal (2022), 107668, database is CAplus.

In this paper, a three-dimensional (3D) polyfunctional group and thermal controlled polymer p(POSS-co-DMAEMA) was prepared based on the chem. structure of the phthalic acid easters (PAEs) and applied as an extractant for dispersive liquid-liquid microextraction (DLLME) in combination with HPLC-UV. The polymer with good biocompatibility can be dispersed and aggregated by shaking and heating based on the thermal controlled properties without the assistance of instruments, which shortened the DLLME process as low as 5 min. The feasibility of the developed method was verified using 5 PAEs as targets in simulated water samples, which showed good precision (RSD%, 1.3-10.0, n = 3) and low detection limit (0.19-0.52 ng mL-1) under the optimal extraction conditions. This proposed method was successfully applied in analyzing four straws and good spiked recoveries over the range of 91.60-128.00% were obtained. Furthermore, mol. docking was employed to explore the mol. interactions and calculate binding energies between the polymer and organic pollutants, ensuring the synthesized polymer has a strong extraction ability for PAEs. The satisfied extraction efficiency can be attributed to the fact that the p(POSS-co-DMAEMA) is water-soluble at room temperature but hydrophobic at high temperature, and the high extraction ability can be achieved by the strong intermol. forces between the polymer and PAEs. The exptl. results suggest that the proposed method holds good promise for the trace anal. of PAEs.
