Abstract ：
Glycosyl sulfonamides have been identified as novel inhibitors of carbonic anhydrase, showing great potential for cancer treatment. However, previous approaches to synthesizing glycosyl sulfonamides require multi steps, resulting in low efficiency and being time-consuming. Herein, we disclose a reductive coupling strategy that enables the modular synthesis of glycosyl sulfonamide using readily accessible glycosyl sulfinates and feedstock chemical nitroarenes. This method allows for the construction of rarely reported N-aryl glycosyl sulfonamides and exhibits tolerance to a variety of functional groups.

Abstract ：
A stereoselective pyridinium hexafluorophosphate-catalyzed C-glycosylation of indole is presented, featuring the plausible formation of a catalyst-acceptor complex and a crucial H-bond between the N-H group of indole and the oxygen atom at the C6 position of the glycosyl donor, which are proposed to collectively facilitate the glycosylation process. This reaction proceeds under mild conditions, enabling the selective synthesis of a wide range of C-indolyl glycosides.

Abstract ：
A series of new silicon(IV) phthalocyanines (SiPcs) di-substituted axially with different nucleoside moieties have been synthesized and evaluated for their singlet oxygen quantum yields (Phi(Delta)) and in vitro photodynamic activities. The adenosine-substituted SiPc shows a lower photosensitizing efficiency (Phi(Delta) = 0.35) than the uridine- and cytidine-substituted analogs (Phi(Delta) = 0.42-0.44), while the guanosine-substituted SiPc exhibits a weakest singlet oxygen generation efficiency with a Phi(Delta) value down to 0.03. On the other hand, replacing axial adenosines with chloro-modified adenosines and purines can result in the increase of photogenerating singlet oxygen efficiencies of SiPcs. The formed SiPcs 1 and 2, which contain monochloro-modified adenosines and dichloro-modified purines respectively, appear as efficient photosensitizers with Phi(Delta) of 0.42-0.44. Both compounds I and 2 present high photocytotoxicities against HepG2 and BGC823 cancer cells with IC50 values ranging from 9 nM to 33 nM. The photocytotoxicities of these two compounds are remarkably higher than the well-known anticancer photo sensitizer, chlorin e6 (IC50 = 752 nM against HepG2 cells) in the same condition. As revealed by confocal microscopy, for both cell lines, compound I can essentially bind to mitochondria, while compound 2 is just partially localized in mitochondria. In addition, the two compounds induce cell death of HepG2 cells likely through apoptosis. (C) 2016 Elsevier B.V. All rights reserved.

Abstract ：
Molecular conformation is an important issue related to the self-assembly architecture and property. The self-assembly of silicon(IV) phthalocyanines covalently linked to the 5-N-cytidine or 4-carboxyphenoxy moiety at the axial positions, namely, SiPc(NC)(2) and SiPc(CP)(2), respectively, has been studied by means of scanning tunneling microscopy (STM) at the solid-liquid interface. The intermolecular axial hydrogen bonding in combination with the stabilizing role of the TCDB template brings about supramolecular selfassembled structures of silicon(IV) phthalocyanines in an edge-on orientation. Two pyridine compounds, 4,4'-bipyridine (BPY) and 1,2-di(4-pyridy0ethylene (DPE), can tune the supramolecular structure, leading to interestingly axial self-assemblies of SiPc(CP)(2) with BPY and DPE in an edge-on manner by hydrogen bonding. The results indicate that the axial substituents and the axial ligands can regulate and precisely control the conformation and arrangement of the phthalocyanine moiety on the graphite surface.

Abstract ：
Three coordination polymers based on a tridentate N-3-coordinated anthracene-containing tripodal ligand, 9-[(2,2'-dipicolylamino) methyl]anthracene (ADPA), namely [Cu(ADPA)Cl-2]center dot H2O (1), [Ru(ADPA)Cl-2-DMSO]center dot 4CH(3)OH center dot 2H(2)O (2), and [Pt(ADPA)Cl]PF6 center dot DMSO center dot 2CH(3)OH center dot H2O (3), were synthesized and characterized using elemental analysis, H-1 NMR, C-13 NMR, FT-IR, and UV-vis spectroscopies, H RMS, and single-crystal XRD. X-ray structural analysis showed that the three compounds have mononuclear, 0D structures, which are further connected by hydrogen bonds into 3D supramolecular architectures. The antimicrobial activities of ADPA and compounds 1-3 were evaluated based on the minimum inhibitory concentration and minimum bactericidal concentration. The results showed that compounds 1-3 exhibit significant activities against Gram-positive bacteria (Staphylococcus aureus), and the Ru(II) and Pt(II) compounds have moderate antifungal activities (Candida albicans).

Abstract ：
The pyrene-appended dipicolylamine ligand (L) and its Cu(II) and Pt(II) compounds have been synthesized and characterized by elemental analysis, H-1- and C-13-NMR, HRMS, FT-IR andUV-Vis analyses. Furthermore, the crystal structures of H2L center dot 2ClO(4), [(CuLClO4CH3CN)ClO4] and [(PtLCl)DMSO] (DMSO = dimethyl sulfoxide) have been determined by single-crystal X-ray diffraction. The antimicrobial activities of these compounds were determined towards Gram-positive (Staphylococcus aureus ATCC-25923) and Gram-negative (Escherichia coli ATTC-25922) trains of bacteria, as well as the fungal strain Candida albicans ATCC-10213, and the results were compared with those of L alone. The results of these experiments showed that the Cu(II) and Pt(II) compounds of L exhibited stronger antibacterial and antifungal activities than the ligand.
