Nomura, Takuhiro;Ryukan, Makoto;Matsuoka, Shin-ichi;Suzuki, Masato research published 《 Cooligomerization of γ-butyrolactone with (meth)acrylates catalyzed by N-heterocyclic carbene: Low possibility of hybrid copolymerization》, the research content is summarized as follows. Copolymerization between lactones and vinyl monomers has significant implications for the synthesis of new polymeric materials; however, a highly reactive cyclic monomer, e.g., ε-caprolactone (CL), leads to a copolymeric product but with a complex structure remaining to be elucidated. Herein, we present cooligomerizations of γ-butyrolactone (γBL), a low-polymerizable cyclic monomer, with (meth)acrylates catalyzed by an N-heterocyclic carbene (NHC) under conditions in which no reaction occurs in the absence of either comonomer. Several exptl. studies indicate that the product is not a hybrid cooligomer with an ester linkage in the main chain but a graft cooligomer. The reaction mechanism involves the generation of the γBL enolate by the NHC to initiate oligomerizations of γBL and (meth)acrylates followed by the transesterification of oligo (γBL) with an ester unit of (meth)acrylates. These results prompted us to investigate the previously reported structure of copolymer of CL and Me methacrylate obtained by a phosphazene base catalyst. The hydrolysis experiment revealed that the copolymeric product turned out not to be a hybrid random copolymer.

Nian, Shifeng;Fan, Zhouhao;Freychet, Guillaume;Zhernenkov, Mikhail;Redemann, Stefanie;Cai, Li-Heng research published 《 Self-Assembly of Flexible Linear-Semiflexible Bottlebrush-Flexible Linear Triblock Copolymers》, the research content is summarized as follows. Block copolymer (BCP) self-assembly is a fundamental process in which incompatible blocks spontaneously form organized microstructures with broad practical applications. Classical understanding is that the domain spacing is limited by the contour length of the polymer backbone. Here, using a combination of mol. design, chem. synthesis, small-/wide-angle X-ray scattering, transmission electron microscopy, and electron tomog., we discover that this mol. picture does not hold for architecturally semiflexible BCPs. For strongly segregated linear-semiflexible bottlebrush-linear triblock copolymers, the size of the bottlebrush domain can be twice the bottlebrush backbone contour length. The mechanism of such anomalous self-assembly is likely that the interfacial repulsion between the incompatible blocks is large enough to pull a part of the linear end blocks into the bottlebrush domain. This effectively increases the bottlebrush domain size. Moreover, the semiflexible bottlebrush widens the regime for the cylinder morphol. that is associated with the volume fraction of the end blocks f_C^SFBmem (0.10, >0.41). This window is much wider than that for flexible linear BCPs, f_C^F mem (0.14, 0.35), and that predicted by the recent SCF theory for linear-bottlebrush BCPs of the same chem. and mol. architecture. Our exptl. findings reveal previously unrecognized mechanisms for the self-assembly of architecturally complex BCPs.

Nguyen, Thuy;Gamage, Thomas F.;Decker, Ann M.;Barrus, Daniel;Langston, Tiffany L.;Li, Jun-Xu;Thomas, Brian F.;Zhang, Yanan research published 《 Synthesis and Pharmacological Evaluation of 1-Phenyl-3-Thiophenylurea Derivatives as Cannabinoid Type-1 Receptor Allosteric Modulators》, the research content is summarized as follows. Authors previously reported diarylurea derivatives as cannabinoid type-1 receptor (CB1) allosteric modulators which were effective in attenuating cocaine seeking behavior. Herein, authors extended the structure-activity relationships of PSNCBAM-1 I at the central Ph ring directly connected to the urea moiety. Replacement with a thiophene ring led to II with improved or comparable potencies in calcium mobilization, [35S]GTPγS binding, and cAMP assays, whereas substitution with non-aromatic rings led to significant attenuation of the modulatory activity. These compounds had no inverse agonism in [35S]GTPγS binding, a characteristic that is often thought to contribute to adverse psychiatric effects. While compound II had good metabolic stability in rat liver microsomes, it showed modest solubility and blood-brain barrier permeability. Compound II showed an insignificant attenuation of cocaine seeking behavior in rats, most likely due to its limited CNS penetration, suggesting that pharmacokinetics and distribution play a role in translating the in vitro efficacy to in vivo behavior.

Nauman, Nida;Boyer, Cyrille;Zetterlund, Per B. research published 《 Miniemulsion polymerization via membrane emulsification: Exploring system feasibility for different monomers》, the research content is summarized as follows. Membrane emulsification using pore sizes of 100 and 800 nm in conjunction with miniemulsion polymerization has been investigated for monomers with varying water solubilities, namely, styrene, Bu methacrylate (nBMA), benzyl methacrylate (BzMA), and Bu acrylate (nBA), and compared with previous work on Me methacrylate (MMA). The O/W interfacial tension is an important parameter for 100 nm pore size (but less so for 800 nm pore size) – increasing O/W interfacial tension leads to an increase in membrane emulsification time as well as increases in the monomer droplet size and particle size. The most nonpolar monomer styrene required impractically long emulsification times. For the other monomers, the miniemulsions were polymerized by radical polymerization, resulting in monomodal particle size distributions. Overall, the results demonstrate that membrane emulsification in tandem with miniemulsion polymerization is a convenient method for synthesis of well-defined polymer nanoparticles of various monomers in the approx. size range 200-3500 nm.

AMPK plays a critical role regulating cell metabolism, growth and survival. Interfering with this enzyme activity has been extensively studied as putative mechanism for cancer therapy. The present work aims to identify a specific AMPK activator for cancer cells among a series of novel heterocyclic compounds A series of novel hybrid heterocyclic compounds, namely naphtoquinone-4-oxoquinoline and isoquinoline-5,8-quinone-4-oxoquinoline derivatives, were synthesized via Michael reaction and their structures confirmed by spectral data: IR; ¹H and ¹³C NMR spectroscopy (COSY, HSQC, HMBC); and high-resolution mass spectrometry (HRMS). The novel compounds were screened and tested for antitumoral activity and have part of their mechanism of action scrutinized. Here, we identified a selective AMPK activator among the new hybrid heterocyclic compounds This new compound presents selective cytotoxicity on breast cancer cells but not on non-cancer counterparts. We identified that by specifically activating AMPK in cancer cells, the drug downregulates unfolded protein response pathway, as well as inhibits mTOR signaling. These effects, that are selective for cancer cells, lead to activation of autophagy and, ultimately, to cancer cells death. Taken together, our data support the promising anticancer activity of this novel compound which is a strong modulator of metabolism

Elastic/glassy Janus composite particles having snowman-like shape were successfully prepared by seeded polymerization of benzyl methacrylate (BzMA) in the presence of cross-linked silicone particles. The morphol. of the composite particles was strongly affected by the affinity between silicone seed particles and monomer.
