Su, Shijun;Zhou, Qing;Tang, Xuemei;Peng, Feng;Liu, Tingting;Liu, Liwei;Xie, Chengwei;He, Ming;Xue, Wei research published 《 Design, synthesis, and antibacterial activity of novel myricetin derivatives containing sulfonate》, the research content is summarized as follows. A series of myricetin derivatives containing sulfonate groups I (R = Ph, 2-chlorophenyl, 2-thienyl, etc.) was designed and synthesized. Preliminary antibacterial activity showed that most of the target compounds I exhibited significant biol. activities against Xanthomonas axonopodis pv. In particular, the EC₅₀ value of compound I (R = 4-nitrophenyl) was 13.76μg/cm³ against Xac, which was better than com. reagents bismerthiazol (50.32μg/cm³) and thiodiazole copper. (83.27μG/cm³), and the EC₅₀ value of compound I (3-chlorophenyl) was 11.92μg/cm³ against Xoo in vitro and the result was better than that of bismerthiazol (72.08μg/cm³) and thiodiazole copper (99.26μg/cm³). Compound I (R = 3-chlorophenyl) displayed the better in vivo activity against rice bacterial leaf blight than bismerthiazol and thiodiazole copper. Meanwhile, the antibacterial mechanism of compounds I (R = 4-nitrophenyl) and I (R = 3-chlorophenyl) was studied by scanning electron microscope (SEM). These results suggested that myricetin derivatives containing sulfonate I can be considered as new antibacterial reagents.

Summer, Samantha L.;Kell, Steven A.;Zhu, Zongjian;Moore, Rhonda;Liotta, Dennis C.;Myers, Scott J.;Koszalka, George W.;Traynelis, Stephen F.;Menaldino, David S. research published 《 Di-aryl sulfonamide motif adds π-stacking bulk in negative allosteric modulators of the NMDA receptor》, the research content is summarized as follows. The N-methyl-D-aspartate receptor plays a critical role in central nervous system processes. Its diverse properties, as well as hypothesized role in neurol. disease, render NMDA receptors a target of interest for the development of therapeutically relevant modulators. A number of subunit-selective modulators have been reported in the literature, one of which is TCN-201, a GluN2A-selective neg. allosteric modulator. Recently, it was determined from a cocrystn. study of TCN-201 with the NMDA receptor that a unique active pose exists in which the sulfonamide group of TCN-201 incorporates a π-π stacking interaction between the two adjacent aryl rings that allows it to make important contacts with the protein. This finding led us to investigate whether this unique structural feature of the diaryl sulfonamide could be incorporated into other modulators that act on distinct pockets. To test whether this idea might have more general utility, we added an aryl ring plus the sulfonamide linker modification to a previously published series of GluN2C- and GluN2D-selective neg. allosteric modulators that bind to an entirely different pocket. Herein, we report data suggesting that this structural modification of the NAB-14 series of modulators was tolerated and, in some instances, enhanced potency. These results suggest that this motif may be a reliable means for introducing a π-π stacking element to mol. scaffolds that could improve activity if it allowed access to ligand-protein interactions not accessible from one planar aromatic group.

Among the works of the last decade, a literature search revealed spirothiazamenthane, which has served as a lead in the development of derivatives active against resistant viral strains. In this work, the novel mol. scaffold, which resembles spirothiazamenthane, but combines isoxazoline as a heterocycle and cyclooctane ring as a hydrophobic part of the structure is reported. The synthesis of new 3-nitro- and 3-aminoisoxazolines containing spiro-fused or 1,2-annelated cyclooctane fragments was achieved by employing 1,3-dipolar cycloaddition of 3-nitro-4,5-dihydroisoxazol-4-ol 2-oxide or tetranitromethane-derived alkyl nitronates with non-activated alkenes. A series of spiro-sulfonamides was obtained by the reaction of 3-aminoisoxazoline containing a spiro-fused cyclooctane residue with sulfonyl chlorides. Preliminary screening of the compounds for antiviral, antibacterial, antifungal and antiproliferative properties in vitro revealed 1-oxa-2-azaspiro[4.7]dodec-2-en-3-amine and 3a,4,5,6,7,8,9,9a-octahydrocycloocta[d]isoxazol-3-amine with activity against the influenza A/Puerto Rico/8/34 (H1N1) virus in the submicromolar range, and high values of selectivity index. Further study of the mechanism of the antiviral action of these compounds, and the synthesis of their analogs, is likely to identify new agents against resistant viral strains.

A practical, catalytic entry to α,α,α-trisubstituted (α-tertiary) primary amines by C-H functionalization has long been recognized as a critical gap in the synthetic toolbox. The authors report a simple and scalable solution to this problem that does not require any in situ protection of the amino group and proceeds with 100% atom-economy. The authors’ strategy, which uses an organic photocatalyst in combination with azide ion as a hydrogen atom transfer (HAT) catalyst, provides a direct synthesis of α-tertiary amines, or their corresponding γ-lactams. The authors anticipate that this methodol. will inspire new retrosynthetic disconnections for substituted amine derivatives in organic synthesis, and particularly for challenging α-tertiary primary amines.

Hippo signalling pathway plays a crucial role in tumorigenesis and cancer progression. In this work, we identified an N-aryl sulfonamide-quinazoline derivative, compound as an anti-gastric cancer agent, which exhibited potent antiproliferative ability with IC50 values of 0.36 μM (MGC-803 cells), 0.70 μM (HCT-116 cells), 1.04 μM (PC-3 cells), and 0.81 μM (MCF-7 cells), resp. and inhibited YAP activity by the activation of p-LATS. Compound was effective in suppressing MGC-803 xenograft tumor growth in nude mice without obvious toxicity and significantly down-regulated the expression of YAP in vivo. Compound arrested cells in the G2/M phase, induced intrinsic apoptosis, and inhibited cell colony formation in MGC-803 and SGC-7901 cells. Therefore, compound is to be reported as an anti-gastric cancer agent via activating the Hippo signalling pathway and might help foster a new strategy for the cancer treatment by activating the Hippo signalling pathway regulatory function to inhibit the activity of YAP.
