Control of the bottom-up self-assembly of ionic bent-core dendrimers has been systematically studied by mol. design. This process gave rise to architectures with diverse packing, shapes and dimensions to construct structured materials at the nanoscale. The compact organization of the mols. achieved in bent-core mesophases was transferred or induced to self-assemblies in the presence of water – even in the case of non-mesogenic dendrimers. The subtle balance of mol.-mol. and mol.-solvent interactions regulated the morphol. of the aggregates and these ranged from rods, non-twisted or twisted fibers, helical ribbons and nanotubes. The structure obtained was dependent on the choice of dendritic nucleus, the bent-core structure (from 5 to 3 aromatic ring systems), the lateral moiety and the length of the outer flexible tails. The rigid nature of the chem. structure controlled the type of mol. packing in the layers and allowed mol. conformational chirality to be transmitted to the supramol. aggregates, despite achiral mols. being used. The short/long terminal chain lengths determined the type of curvature of the ribbons. Some of these self-assemblies are proposed as alternatives to the attractive and widely applied helical nanofilaments formed by bent-core mesogens, but, thanks to their amphiphilic nature, the novel compounds can be processed from solution Moreover, the self-assembly process was studied in an effort to elucidate the aggregation mechanism of these bent-shaped amphiphiles and to define exptl. protocols to provide high quality and homogeneous aggregates. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2COA of Formula: C13H12O2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market.

A very long-acting parp inhibitor suppresses cancer cell growth in DNA repair-deficient tumor models was written by Fontaine, Shaun D.;Ashley, Gary W.;Houghton, Peter J.;Kurmasheva, Raushan T.;Diolaiti, Morgan;Ashworth, Alan;Peer, Cody J.;Nguyen, Ryan;Figg, William D. Sr.;Beckford-Vera, Denis R.;Santi, Daniel V.. And the article was included in Cancer Research in 2021.Category: ethers-buliding-blocks The following contents are mentioned in the article:

PARP inhibitors are approved for treatment of cancers with BRCA1 or BRCA2 defects. In this study, we prepared and characterized a very long-acting PARP inhibitor. Synthesis of a macromol. prodrug of talazoparib (TLZ) was achieved by covalent conjugation to a PEG_40kDa carrier via a β-eliminative releasable linker. A single injection of the PEG~TLZ conjugate was as effective as ~30 daily oral doses of TLZ in growth suppression of homologous recombination-defective tumors in mouse xenografts. These included the KT-10 Wilms′′ tumor with a PALB2 mutation, the BRCA1-deficient MX-1 triple-neg. breast cancer, and the BRCA2-deficient DLD-1 colon cancer; the prodrug did not inhibit an isogenic DLD-1 tumor with wild-type BRCA2. Although the half-life of PEG~TLZ and released TLZ in the mouse was only ~1 day, the exposure of released TLZ from a single safe, ED of the prodrug exceeded that of oral TLZ given daily over one month. μPET/CT imaging showed high uptake and prolonged retention of an 89Zr-labeled surrogate of PEG~TLZ in the MX-1 BRCA1-deficient tumor. These data suggest that the long-lasting antitumor effect of the prodrug is due to a combination of its long t_1/2, the high exposure of TLZ released from the prodrug, increased tumor sensitivity upon continued exposure, and tumor accumulation. Using pharmacokinetic parameters of TLZ in humans, we designed a long-acting PEG~TLZ for humans that may be superior in efficacy to daily oral TLZ and would be useful for treatment of PARP inhibitor-sensitive cancers in which oral medications are not tolerated. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Category: ethers-buliding-blocks).

2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Bovine Serum Albumin (BSA) lipid hybrid nanoparticles are part of the new solutions to overcome low bioavailability of poor solubility drugs such as curcuminoids, which possess multiple biol. advantages; however, they are counterbalanced by its short biol. half-life. In this line, we prepared the three main curcuminoids: curcumin (CUR), desmethoxycurcumin (DMC), and bisdemethoxycurcumin (BDM)-loaded BSA nanoparticles. The three formulations were characterized by the average size, size distribution, crystallinity, weight loss, drug release, kinetic mechanism, and antioxidant activity. The developed method produced CUR-, DMC-, and BDM-loaded BSA nanoparticles with a size average of 15.83 ± 0.18, 17.29 ± 3.34, and 15.14 ± 0.14 nm for CUR, DMC, and BDM loaded BSA, resp.

A series of nonionic disaccharide-based surfactants alkyl-di(oxyethylene) β-D-maltosides ( n = 6-16), e.g. I, were synthesized, and their physicochem. properties were further investigated. Six β-D-maltosides (n = 8-16) exhibited a fan-shaped texture feature, whereas hexyl-di(oxyethylene) β-D-maltoside had the strongest hygroscopicity. Owing to the incorporation of the hydrophilic dioxyethyl spacer (-(OCH₂CH₂)₂-), the related water solubility improved significantly. Tetradecyl-di(oxyethylene) β-D-maltoside had good water solubility, whereas hexadecyl-di(oxyethylene) β-D-maltoside had weak water solubility Meanwhile, the surface tension of β-D-maltosides (n = 6-14) had a decreasing tendency with increasing the alkyl chain length, whereas 4g had the best surface activity. Furthermore, decyl-di(oxyethylene) β-D-maltoside had the best foaming ability and foam stability. Dodecyl-di(oxyethylene) β-D-maltoside I had the best emulsifying property in the rapeseed oil/water system. In contrast, both ammonium dodecyl sulfate (NH₄DS)/I and cetyltrimethylammonium chloride (CTAC)/I binary surfactant systems showed a synergistic effect in surface activity because the C_CMC/CMC^id_mix was <1. NaCl impacted the surface activity of the aqueous I solution through salt-surfactant synergistic effects.

Evidence of corresponding states in ternary microemulsions of water-alkane-C_iE_j was written by Sottmann, T.;Strey, R.. And the article was included in Journal of Physics: Condensed Matter in 1996.HPLC of Formula: 112-59-4 The following contents are mentioned in the article:

Exptl. evidence of corresponding states in water, n-alkane (C_κH_2κ+2), and n-alkyl polyethylene glycol ether (C_iE_j) systems is presented. Striking similarities in both the phase behavior and the interfacial tensions for a variety of systems are highlighted. For some selected systems the trajectories f the middle phases in the three-phase regime are precisely determined Projections of the middle-phase trajectories onto the ϕ_c-ϕ plane of the phase prism shape nearly perfect parabolae, whereas the projections onto the T-ϕ plane exhibit a sigmoidal shape. Here ϕ_c is the surfactant volume fraction, and ϕ is the oil-in-water-plus-oil volume fraction. It is found that the trajectories collapse into single curves, if the surfactant concentration scale is reduced by the maximum of the parabolae, ϕ̅_c, which is the surfactant volume fraction of the sym. microemulsion, and if the temperature axis is reduced by the difference of the upper and lower critical endpoint temperature, T_u-T_l. It is found that the maximum length scale ξ̅ α ϕ̅_c^-1 set by the surfactant volume fraction can be used to reduce the interfacial tension scale, that is plotting σ_abϕ̅_c^-2 vs. the reduced temperature scale. These reductions yield a remarkable superposition of the interfacial tension data of 17 different systems, the carbon number of the oil κ ranging from 8 to 14, the hydrophilic surfactant head j from 3 to 6 and the surfactant tail length i from 8 to 12.

Gas chromatography/electron ionization mass spectrometric analysis of oligomeric Polyethylene Glycol Monoalkyl Ethers was written by Onigbinde, Adebayo O.;Munson, Burnaby;Amos-Tautua, Bamidele M. W.. And the article was included in Research Journal of Applied Sciences, Engineering and Technology in 2013.SDS of cas: 112-59-4 The following contents are mentioned in the article:

Polyethylene Glycol Monoalkyl Ethers, C_xH_2x+1(OC₂H₄)_nOH, (PEGMAE), are polar compounds like Polyethylene Glycols (PEG) and they undergo microbial degradation which produces toxic substances that are potentially dangerous to the environment. Therefore, the purpose of this study is to carry out proper identification and characterization of these compounds The Electron Ionization (EI) and Chem. Ionization (CI) spectra of various PEGMAE were obtained by Gas Chromatog./Mass Spectrometry (GC/MS) and were used to identify and characterize these compounds The characteristic cleavages in the EI and CI reactions of PEGMAEs were also studied. The results obtained showed that the methane CI mass spectra of the PEGMAE contain MH⁺ ions and fragment ions similar to those found in their EI mass spectra. The relative abundances of the MH⁺ ions are low, variable and increase with increasing sample size across the chromatog. peaks; but do not increase with increasing x or n. The base peaks of the low mass oligomers (x ≤ 3) are PEG related (e.g., m/z 45, 59) but those of higher mass oligomers (x ≥ 4) include the ion at m/z 63 (HOC₂H₄OH)H⁺ or m/z 107 (HO(C₂H₄O)₂H)H⁺. There are no (MH-H₂O)⁺ ions or protonated dimer ions (n ≥ 2, x ≥ 2) in the spectra of PEGMAE. The Relative Molar Sensitivities (RMS) or the Relative Sensitivity per G (RSG) increases linearly with mol. polarizabilty or mol. weight with a non-zero intercept.

Low-surfactant microemulsion, a smart strategy intended for curcumin oral delivery was written by Dourado, Douglas;Oliveira, Matheus Cardoso de;Araujo, Guilherme Rodolfo Souza de;Amaral-Machado, Lucas;Porto, Dayanne Lopes;Aragao, Cicero Flavio Soares;Alencar, Everton do Nascimento;Egito, Eryvaldo Socrates Tabosa do. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2022.Name: Bisdemethoxycurcumin The following contents are mentioned in the article:

This study aimed to develop a low surfactant concentration curcumin-loaded microemulsion (Curc-ME) having a gastrointestinal pH resistance, intended to prospect its oral use for further curcumin release. The effect of excipients on the apparent solubility of curcumin was assessed and a pseudo ternary phase diagram was designed to produce a low-surfactant microemulsion (ME) system. Curcumin was incorporated into the ME (Curc-ME), and the system was further physicochem. and phys. characterized. The entrapment efficiency (EE) was determined by UHPLC. The systems′ stability under storage, and its stability and curcumin release in simulated gastrointestinal fluids (SGIF) were evaluated. The excipients of the ME improved curcumin′s apparent solubility Curc-ME, stabilized with 15% of surfactants, displayed spherical droplets (sized of 21.81 ± 0.20 nm), polydispersity index of 0.07 ± 0.01, viscosity of 5.33 x 10-3 ± 0.01 Pa.s, conductivity of 160 ± 3 μS cm-1, surface tension of 40.37 ± 0.48 dynes/cm and EE of 98 ± 0.73%. Thermal analyses confirmed curcumin entrapment in the core of the system. The system remained stable over 90 days under storage and under SGIF conditions. Curc-ME revealed a modified and complex kinetics release of curcumin in the SGIF. Overall, the results demonstrate that Curc-ME increased the solubility of curcumin, was produced with a remarkable low surfactant concentration, and showed stability and modified curcumin release at the gastrointestinal tract pHs. Therefore, Curc-ME revealed to be a promising candidate to be further explored as a therapeutic agent.
