GPR81 is a novel drug target that is implicated in the control of glucose and lipid metabolism The lack of potent GPR81 modulators suitable for in vivo studies has limited the pharmacol. characterization of this lactate sensing receptor. We performed a high throughput screen (HTS) and identified a GPR81 agonist chem. series containing a central acyl urea scaffold linker. During SAR exploration two addnl. new series were evolved, one containing cyclic acyl urea bioisosteres and another a central amide bond. These three series provide different selectivity and physicochem. properties suitable for in-vivo studies.

Dai, Jun;Wang, Zhuang;Deng, Yuhua;Zhu, Lei;Peng, Fangzhi;Lan, Yu;Shao, Zhihui research published 《 Enantiodivergence by minimal modification of an acyclic chiral secondary aminocatalyst》, the research content is summarized as follows. By designing a class of reactive and stereoselective organocatalysts, acyclic chiral secondary amines, e.g., [(2S)-1-(diethylamino)-3-phenylpropan-2-yl](2-methylpropyl)amine, a method for achieving the enantiodivergence is developed simply by changing the secondary N-i-Bu- to N-Me-group within the catalyst architecture while maintaining the same absolute configuration of the catalysts, which modulates the catalyst conformation. This catalyst-controlled enantiodivergent method not only enable challenging asym. transformations to occur in an enantiodivergent manner but also features a high level of stereocontrol and broad scope that is demonstrated in eight different reactions (90 examples), all delivering both enantiomers of a range of structurally diverse products, e.g., tert-Bu ((3S,4R)-4-methyl-2-oxo-3-(phenylethynyl)tetrahydrofuran-3-yl)carbamate including hitherto less accessible, yet important, compounds in good yields with high stereoselectivities.

Dadashi-Silab, Sajjad;Kim, Khidong;Lorandi, Francesca;Schild, Dirk J.;Fantin, Marco;Matyjaszewski, Krzysztof research published 《 Effect of halogen and solvent on iron-catalyzed atom transfer radical polymerization》, the research content is summarized as follows. Efficient transfer of halogen atoms is essential for controlling the growth of polymers in atom transfer radical polymerization (ATRP). The nature of halogens may influence the efficiency of the halogen atom transfer during the activation and deactivation processes. The effect of halogens can be associated with the C-X bond dissociation energy and the affinity of the halogens/halides to the transition metal catalyst. In this paper, we study the effect of halogens (Br vs. Cl) and reaction media in iron-catalyzed ATRP in the presence of halide anions as ligands. In Br-based initiating systems, polymerization of methacrylate monomers was well-controlled, whereas Cl-based initiating systems provided limited control over the polymerization The high affinity of the Cl atom to the iron catalyst renders it less efficient for fast deactivation of growing chains, resulting in polymers with mol. weights higher than predetermined by Δ[M]/[RX]o and with high dispersities. Conversely, Br can be exchanged with higher efficiency and hence provided good control over polymerization Decreasing the polarity of the reaction medium improved the polymerization control. Polymerizations using ppm levels of the iron catalyst in acetonitrile (a more polar solvent) yielded polymers with larger dispersity values due to the slow rate of deactivation as opposed to the less polar solvent anisole, which afforded well-controlled polymers with dispersity <1.2.

Criton, Thomas;Vilona, Debora;Jacob, Guy;Medebielle, Maurice;Dumont, Elise;Joucla, Lionel;Lacote, Emmanuel research published 《 Synthesis and Properties of Higher Nuclearity Polyazanes》, the research content is summarized as follows. Polyazanes (i.e., higher nuclearity homologues of hydrazines) with increasing numbers of bound nitrogen atoms (from 3 to 5), including the first pentazane ever described, were prepared by the addition of lower-order polyazanes to diazo reagents. It was shown that the polynitrogen chains adopt a helical conformation.

Several phenanthrolinic analogs of quinolones I [R¹ = OH, NH₂, OEt, NHNH₂, NHPh; R² = H, Cl, Br, NO₂; R³ = H, Me, Et; R⁴ = H, NO₂] were synthesized and their antibacterial activity tested against Mycobacterium tuberculosis, other mycobacterial species and bacteria from other genera. Some of them show high activity (of the range observed for rifampicin) against M. tuberculosis replicating in vitro and in vivo (infected macrophages) conditions. These derivatives showed the same activity with all or several M. tuberculosis complex bacterial mutants resistant to fluoroquinolones (FQ). This opened the way to the construction of new drugs for the treatment of FQ resistant bacterial infections, including tuberculosis. Several compounds showed also activity against Staphylococcus aureus and probably other species. These compounds did not showed major toxicity.

Clothier, Glenn K. K.;Guimaraes, Thiago R.;Moad, Graeme;Zetterlund, Per B. research published 《 Expanding the Scope of RAFT Multiblock Copolymer Synthesis Using the Nanoreactor Concept: The Critical Importance of Initiator Hydrophobicity》, the research content is summarized as follows. Precise multiblock copolymer synthesis coupled with self-assembly offers morphol. control on length scales ranging from a few nanometers to micrometer scale, providing enormous opportunities for future development of advanced materials and applications. The scope of multiblock copolymer synthesis via RAFT polymerization has recently been expanded by application of the nanoreactor concept for emulsion polymerization This enabled use of slow propagating monomers, such as styrenes and methacrylates, in multiblock synthesis. However, severe limitations attributed to the high polymer glass transition temperature (T_g) of some polymers have hitherto remained. The use of monomers that give such high T_g polymer effectively prevented penetration of aqueous phase-generated radicals into the polymer particles wherein the RAFT functionality is located. We here demonstrate that these constraints can be relieved by judicious choice of the radical initiator. Multiblock homopolymers were synthesized by seeded RAFT emulsion polymerization using initiators that differ substantially in hydrophobicity. Ten sequential chain extensions using tert-Bu methacrylate (T_g of PtBMA = 118°C) with targeted block DP = 100 were conducted at 80°C for each initiator. Markedly narrower mol. weight distributions were obtained when more hydrophobic initiators were used. The same polymerizations targeting low T_g polymer (PnBMA; T_g = 20°C) resulted in only minor differences in control when the different initiators were used, supporting our hypothesis on the role of radical penetration. The present results are anticipated to significantly expand the scope of RAFT polymerization in aqueous emulsion by allowing access to a wider range of low dispersity multiblock copolymers.
