Modulation of Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling is a promising method of treating autoimmune diseases, and the profound potency of clin. compounds makes this mode of action particularly attractive. Other questions that remain unanswered also include: What is the ideal selectivity between JAK1 and JAK3? Which cells are most relevant to JAK blockade? And what is the ideal tissue distribution pattern for addressing specific autoimmune conditions? We hypothesized that JAK3 selectivity is most relevant to low-dose clin. effects and interleukin-10 (IL-10) stimulation in particular, that immune cells are the most important compartment, and that distribution to inflamed tissue is the most important pharmacokinetic characteristic for in vivo disease modification. To test these hypotheses, we prepared modified derivatives of JAK3 specific inhibitors that target C909 near the ATP binding site based on FM-381, first reported in 2016; a compound class that was hitherto limited in uptake and exposure in vivo. These limits appear to be due to metabolic instability of side groups binding in the selectivity pocket. We identified derivatives with improved stability and tissue exposure. Conjugation to macrolide scaffolds with medium chain linkers was sufficient to stabilize the compounds and improve transport to organs while maintaining JAK3 affinity. These conjugates are inflammation targeted JAK3 inhibitors with long tissue half-lives and high exposure to activated immune cells.

Lan, Zhi-An;Wu, Meng;Fang, Zhongpu;Chi, Xu;Chen, Xiong;Zhang, Yongfan;Wang, Xinchen research published 《 A Fully Coplanar Donor-Acceptor Polymeric Semiconductor with Promoted Charge Separation Kinetics for Photochemistry》, the research content is summarized as follows. Charge generation and separation are regarded as the major constraints limiting the photocatalytic activity of polymeric photocatalysts. Herein, two new linear polyarylether-based polymers (PAE-CPs) with distinct linking patterns between their donor and acceptor motifs were tailor-made to investigate the influence of different linking patterns on the charge generation and separation process. Theor. and exptl. results revealed that compared to the traditional single-stranded linker, the double-stranded linking pattern strengthens donor-acceptor interactions in PAE-CPs and generates a coplanar structure, facilitating charge generation and separation, and enabling red-shifted light absorption. With these prominent advantages, the PAE-CP interlinked with a double-stranded linker exhibits markedly enhanced photocatalytic activity compared to that of its single-strand-linked analog. Such findings can facilitate the rational design and modification of organic semiconductors for charge-induced reactions.

Kumar, Neha R.;Agrawal, Abhijeet R.;Choudhury, Aditya;Zade, Sanjio S. research published 《 The Effect of Base and Nucleophile on the Nucleophilic Substitution of Methoxytropone Derivatives: An Easy Access to 4- and 5-Substituted Multifunctional Azulenes》, the research content is summarized as follows. The nucleophilic substitution on 3-substituted 2-methoxytropones to form azulenes is dependent on the nucleophile and base employed. With bulkier nucleophiles (ethyl/methyl cyanoacetate), the reaction proceeds with the abnormal nucleophilic substitution irresp. of the base and with smaller nucleophiles (malononitrile), the reaction follows base-dependent normal and abnormal nucleophilic substitution. Thus, the methodologies are developed to selectively obtain 4- and 5-substituted azulenes based on the nature of bases and nucleophiles employed.

Kumar, Abhinav;Srivastava, Rajendra research published 《 Zirconium Phosphate Catalyzed Transformations of Biomass-Derived Furfural to Renewable Chemicals》, the research content is summarized as follows. This study deals with the development of an economical, ZrPO₄ mediated, one-step catalytic transformation of biomass-derived furfural into synthetic intermediates that have the capability to replace the conventional petrochem.-derived synthetic building blocks. ZrPO₄ is prepared via a highly energy-efficient process at ambient temperature in the eco-friendly ethanol medium. ZrPO₄ exhibits an excellent activity in the transformation of furfural into furfuryl alc. via the eco-friendly, safe, alc. mediated transfer hydrogenation protocol. Furthermore, furfural is also efficiently converted into furfural-derived dihydropyrimidinone and 2-(furan-2-ylmethylene)malononitrile via multicomponent Biginelli and Knoevenagel condensation reactions, resp. Moreover, other structurally homologous biomass-derived reactants such as 5-hydroxymethyl furfural and 2,5-diformyl furan are also compared under the optimized reaction conditions along with conventional petrochem.-derived reactants such as benzaldehyde and 1-heptenal. The high activity of ZrPO₄ is correlated with the acidity/basicity, pyridine FT-IR measurements, and reactant adsorption experiments The catalyst exhibits no significant change in the activity even after five recycles. A non-noble, metal catalyzed, economical, and sustainable process for furfuryl alc. production will certainly motivate chemists and researchers. One simple catalyst affording three functional renewable synthetic intermediates from furfural will attract a significant amount of attention of catalysis researchers and industrialists. The high adsorption of furfural and optimum basicity and the Lewis/Brodonsted acidity of simple and economical amorphous ZrPO₄ are responsible for achieving the excellent activity in the synthesis of furfural-derived renewable chems.

Kumagai, Shohei;Ishii, Hiroyuki;Watanabe, Go;Yu, Craig P.;Watanabe, Shun;Takeya, Jun;Okamoto, Toshihiro research published 《 Nitrogen-Containing Perylene Diimides: Molecular Design, Robust Aggregated Structures, and Advances in n-Type Organic Semiconductors》, the research content is summarized as follows. Conspectus: Organic semiconductors (OSCs) have attracted much attention because of their potential applications for flexible and printed electronic devices and thus have been extensively investigated in a variety of research fields, such as organic chem., solid-state physics, and device physics and engineering. Organic thin-film transistors (OTFTs), a class of OSC-based devices, have been expected to be an alternative of silicon-based metal oxide semiconductor field-effect transistors (MOSFETs), which is the indispensable element for most of the current electronic devices. However, the noncovalently aggregated, van der Waals solid nature of the OSCs, by contrast to covalently bound silicon, conventionally exhibits lower carrier mobilities, limiting the practical applications of OTFTs. In particular, electron-transporting (i.e., n-type) OSCs lag behind their hole-transporting (p-type) counterparts in carrier mobility and ambient stability as OTFTs. This is primarily because of the difficulty in achieving compatibility between the aggregated structure exhibiting excellent carrier mobility and that with enough electron affinity. Recent understandings of carrier transport in OSCs explain that large and two-dimensionally isotropic transfer integrals coupled with small fluctuations are crucial for high carrier mobilities. In addition, from a practical point of view, the compatibility with practical device processes is highly required. Rational mol. design principles, therefore, are still demanded for developing OSCs and OTFTs toward high-end device applications. Herein, we will show our recent progress in the development of n-type OSCs with the key π-electron core (π-core) of benzo[de]isoquinolino[1,8-gh]quinolinetetracarboxylic diimide (BQQDI) on the basis of single-crystal OTFT technologies and the band-transport model enabled by two-dimensional mol. packing arrangements. The critical point is the introduction of electroneg. nitrogen atoms into the π-core: the nitrogen atoms in BQQDI not only deepen the MO energies but also allow hydrogen-bonding-like attractive intermol. interactions to control the aggregated structures, unlike the conventional role of the nitrogen introduced into OSCs only for the former role. Hence, the BQQDI analogs exhibit air-stable OTFT behavior and two-dimensional brickwork packing structures. Specifically, phenethyl-substituted analog (PhC₂-BQQDI) has been shown as the first principal BQQDI-based material, demonstrating solution-processable thin-film single crystals, fewer anisotropic transfer integrals, and an effective suppression of mol. motions, leading to band-like electron-transport properties and stress-durable n-channel OTFT performances, in conjunction with the support of computational calculations Insights into more fundamental points of view have been found by side-chain derivatization and OTFT studies on polycrystalline and single-crystal films. We hope that this Account provides readers with new strategies for designing high-performance OSCs by two-dimensional control of the aggregated structures.
