Dashan, Irem; Balta, Demet Karaca; Temel, Binnur Aydogan; Temel, Gokhan published the artcile< Preparation of Single Chain Nanoparticles via Photoinduced Double Collapse Process>, Application In Synthesis of 1592-20-7, the main research area is chain nanoparticle photoinduced collapse.

A straightforward method is described to achieve polymeric nanoparticles by double folding of single linear chains. The side chain functional polystyrene with controlled mol. weight is converted to pendant azide and benzophenone motifs via postmodification reactions. Resulting functionalized chains undergo intramol. crosslinking upon UV illumination using simultaneous and subsequent pathways at a dilute concentration Particle size of nanoparticles can be tuned by changing the degree of crosslinking using a second folding process. Obtained single and double collapsed chains indicate higher glass transition temperatures and lower hydrodynamic radii compared to their intermediates. To our knowledge, the combination of photoinduced azide crosslinking and radical coupling processes is the first attempt to prepare double folding single polymer chains.

Liu, Jiangtao; Chen, Guofei; Fang, Xingzhong published the artcile< Preparation, characterization, and properties of poly(thioether ether imide)s from isomeric bis(chlorophthalimide)s and bis(4-mercaptophenyl) ether>, Application of C8H3ClO3, the main research area is chlorophthalimide mercaptophenyl ether viscosity solubility thermal stability mech property.

A series of isomeric poly(thioether ether imide)s (PTEIs) containing both thioether and ether linkages were prepared by aromatic nucleophilic substitution reaction of isomeric bis(chlorophthalimide)s (BCPIs) with bis(4-mercaptophenyl) ether (BMPE). The inherent viscosities of synthesized polymers were found in the range of 0.41-0.86 dL g-1 in N-methyl-2-pyrrolidone at 30°C. The glass transition temperature (Tg) of the isomeric PTEIs were 210-242°C and increased by increasing the content of 3-substituted phthalimide unit in the polymer backbone. The 5% weight loss temperature values reached up to 525-539°C under nitrogen and 523-534°C in air atmospheres, resp., which indicated this kind of polyimide possessed excellent thermal stability. Flexible films could be cast from the polymer solution The PTEI films exhibited moderate mech. properties with tensile strengths of 106-127 MPa, elongations at break of 8.6-11.5%, and tensile moduli of 2.2-2.8 GPa, resp. Dynamic mech. thermal anal. results illustrated that the storage moduli (E’) of PTEI (a-e) almost completely maintained at about 2.3 GPa before reaching the corresponding Tg. It is noted that the min. melt viscosity of isomeric PTEIs (a’-e’) decreased by increasing the content of unsym. 3,4′-substituted phthalimide unit in the polymer main chain.

Hsu, Ya- Ling; Hung, Jen-Yu; Tsai, Eing-Mei; Wu, Cheng-Ying; Ho, Ya-Wen; Jian, Shu-Fang; Yen, Meng-Chi; Chang, Wei-An; Hou, Ming-Feng; Kuo, Po-Lin published the artcile< Benzyl butyl phthalate increases the chemoresistance to doxorubicin/cyclophosphamide by increasing breast cancer-associated dendritic cell-derived CXCL1/GROα and S100A8/A9>, Formula: C7H17Cl2N2O3P, the main research area is benzyl butyl phthalate doxorubicin cyclophosphamide chemoresistance breast cancer; CXCL1 GFO S100A8A9 dendritic cell breast cancer chemoresistance.

Phthalates are used as plasticizers in the manufacture of flexible vinyl, which is used in food contact applications. Phthalates have been demonstrated to have an adverse impact on human health, particularly in terms of cancer development. In the present study, we showed for the first time that benzyl Bu phthalate (BBP) potentiates the effect of tumor-associated dendritic cells (TADCs) on the chemoresistance of breast cancer. Specific knockdown anal. revealed that S100A9 is the major factor responsible for the chemoresistance of doxorubicin/cyclophosphamide induced by BBP-stimulated TADCs in breast cancer. BBP exposure also increased tumor infiltrating myeloid-derived suppressor cell (MDSC) secretion of S100A8/A9, thereby exacerbating the resistance of breast cancer to doxorubicin with cyclophosphamide. In addition, BBP also stimulated the production of CXCL1/GROα by TADCs, which increased the angiogenesis of breast cancer in a mouse model. Inhibition of CXCL1/GROα by a neutralizing antibody, decreased the BBP-induced angiogenesis induced by BBP after chemotherapy in the mouse model. These results, for the first time, provide evidence that BBP influences the efficacy of chemotherapy by remodeling the tumor microenvironment of breast cancer.

Chang, Chun-Wei; Lin, Mei-Huei; Wu, Chia-Hui; Chiang, Tsun-Yi; Wang, Cheng-Chung published the artcile< Mapping Mechanisms in Glycosylation Reactions with Donor Reactivity: Avoiding Generation of Side Products>, Application In Synthesis of 128-09-6, the main research area is glycosylation thioglycoside mechanism side product formation.

The glycosylation reaction, which is key for the studies on glycoscience, is challenging due to its complexity and intrinsic side reactions. Thioglycoside is one of the most widely used glycosyl donors in the synthesis of complex oligosaccharides. However, one of the challenges is its side reactions, which lower its yield and limits its efficiency, thereby requiring considerable effort in the optimization process. Herein, we reported a multifaceted exptl. approach that reveals the behaviors of side reactions, such as the intermol. thioaglycon transformation and N-glycosyl succinimides, via the glycosyl intermediate. Our mechanistic proposal was supported by low temperature NMR studies that can further be mapped by utilizing relative reactivity values. Accordingly, we also presented our findings to suppress the generation of side products in solving this particular problem for achieving high-yield glycosylation reactions.

Caswell, Lyman R.; Soo, Lily Y.; Lee, Daisy H.; Fowler, Rosemary G.; Campbell, Jo Anne B. published the artcile< Dipole moments of some 3- and 4- substituted phthalimides and phthalic anhydrides. Influence of steric and resonance effects>, Quality Control of 118-45-6, the main research area is dipole moment phthalimide phthalic anhydride.

The dipole moments of phthalimide, phthalic anhydride, and 16 derivative compounds in dioxane solution were measured and compared. The predicted moments of the derivatives were also calculated from group moments. There is good agreement between the exptl. and predicted dipole moments only for 3-methylphthalic anhydride, 3-fluorophthalimide, 4-methylphthalimide, 3-fluorophthalic anhydride, and 4-methylphthalic anhydride. The Zhdanov-Minkin equation for calculating resonance interaction moments was applied for all of the derivatives Arguments are presented for designating the numerical results of this calculation as ring polarization moments. The results of these calculations show that interaction resonance is significant only for 4-chlorophthalic anhydride. Steric and resonance effects are both small or absent as influences on the dipole moments of 3-fluorophthalic anhydride, 3-fluorophthalimide, and of all methyl derivatives Steric interaction between ortho substituents appears to be large only in the cases of 3-nitrophthalimide and 3-nitrophthalic anhydride.

Lee, Yong Ho; Denton, Elliott H.; Morandi, Bill published the artcile< Palladium-catalysed carboformylation of alkynes using acid chlorides as a dual carbon monoxide and carbon source>, Recommanded Product: 2-(Trifluoromethoxy)benzoyl chloride, the main research area is palladium catalyzed stereoselective carboformylation alkyne acid chloride.

Hydroformylation, a reaction that installs both a C-H bond and an aldehyde group across an unsaturated substrate, is one of the most important catalytic reactions in both industry and academia. Given the synthetic importance of creating new C-C bonds, the development of carboformylation reactions, wherein a new C-C bond is formed instead of a C-H bond, would bear enormous synthetic potential to rapidly increase mol. complexity in the synthesis of valuable aldehydes. However, the demanding complexity inherent in a four-component reaction, utilizing an exogenous CO source, has made the development of a direct carboformylation reaction a formidable challenge. Here, we describe a palladium-catalyzed strategy that uses readily available aroyl chlorides as a carbon electrophile and CO source, in tandem with a sterically congested hydrosilane, to perform a stereoselective carboformylation of alkynes [e.g., 2-methylbenzoyl chloride + i-Pr3SiH + n-PrCCPr-n → (Z)-I (up to 83%)]. An extension of this protocol to four chemodivergent carbonylations further highlights the creative opportunity offered by this strategy in carbonylation chem.
