beta-N-Acetylhexosaminidases are widely distributed exoglycosidases and have attracted significant attention due to their important roles in the field of pesticide and drug discovery. Remarkably, human O-GlcNAcase (hOGA) and human beta-N-acetylhexosaminidase (HsHex) possess the same catalytic mechanism but play different physiological actions in vivo. In this Letter, we aim to improve the inhibitory potency and selectivity of previously reported thioglycosyl-naphthalimides against hOGA. The rational compound design led to the synthesis of 13r bearing a 4-piperidylnaphthalimide moiety as a highly potent hOGA inhibitor (K-i = 0.6 mu M against hOGA) with good selectivity (K-i > 100 mu M against HsHexB). Furthermore, to investigate the basis for the potency and selectivity of 13r against hOGA, the possible inhibitory mechanisms of selected inhibitors (15b, 13b, and 13r) against hOGA and HsHexB were studied using molecular docking and MD simulations. These 4-substituted naphthalimide thioglycosides may potentially serve as useful tools for the further study of the function of hOGA.

The first domino aza-Michael/intramolecular-Michael reaction employing acrylamides as key ambivalent partners for the synthesis of delta-lactams is presented. It has been shown that the desired reactivity is contingent to the presence of an N-alkoxy group within the acrylamides. Thus, in a base-catalyzed process that operates under mild conditions, N-alkoxyacrylamides are readily converted into polysubstituted delta-lactams in good yields with good to excellent stereocontrol.

Rapid and sensitive detection technology is the key to preventing food-borne disease outbreaks. In this study, a low-field nuclear magnetic resonance (NMR) biosensor based on polyamidoamine dendrimers was prepared for the rapid detection of Salmonella in milk. The polyamidoamine dendrimer was biotinylated by amide reaction and chelated to diethylene triamine pentacetate acid and gadolinium to form magnetic complexes. The antibody and magnetic complexes were combined through a streptavidin-biotin system using streptavidin as an intermediate bridge to obtain the immunoprobe. Salmonella was captured by the irnmunoprobe via antigen-antibody interaction and then separated from the mixture by membrane filtration. Finally, the longitudinal relaxation signal of the filtrate was obtained by NMR. The biosensor had excellent anti-interference capability and could detect Salmonella within 1.5 h at a sensitivity of 10(3) cfu mL(-1). This method based on NMR can realize detection in complex samples and has the potential to be a quick and nondestructive method for detecting target bacteria.

An anthracene appended PET chemosensor, anthracene-9-carboxylic acid (3,4-dimethoxy-phenyl)-amide (A(1) ), has been synthesized through condensation of corresponding acyl chloride and 3,4-dimethoxyaniline containing C = O and NH as receptors. The sensor A(1) exhibited selective fluorescence turn-on behavior towards Cu2+ and Zn2+ ions in CH3CN. Cu2+ ions displayed 18-fold enhancement (phi = 0.006 -> 0.071) in the fluorescence spectrum of A(1) , which are otherwise well known for fluorescence quenching phenomenon. Moreover, A(1) could easily discriminate between Zn2+ and Cd2+ ions, the two metal ions of similar nature. The Job’s plots analysis determined 2:1 (A(1) :Cu2+/Zn2+) stoichiometry between the sensor A(1) and Cu2+/Zn2+ ions. The LOD values were calculated to be 1.75 and 3.08 mu M for Cu2+ and Zn2+, respectively.

Degradable polymer prodrugs based on gemcitabine (Gem) as an anticancer drug were synthesized by drug-initiated’ nitroxide-mediated radical ring-opening copolymerization (NMrROP) of methacrylic esters and 2-methylene-4-phenyl-1,3-dioxolane (MPDL). Different structural parameters were varied to determine the best biological performances: the nature of the monomer [i.e., oligo(ethylene glycol) methacrylate (OEGMA) or methyl methacrylate (MMA)], the nature of the Gem-polymer linker (i.e., amide or amide and diglycolate) and the MPDL content in the copolymer. Depending on the nature of the methacrylate monomer, two small libraries of water-soluble copolymer prodrugs and nanoparticles were obtained (M-n approximate to 10000 g mol(-1), D = 1.1-1.5), which exhibited tunable hydrolytic degradation under accelerated conditions governed by the MPDL content. Drug-release profiles in human serum and in vitro anticancer activity on different cell lines enabled preliminary structure-activity relationships to be established. The cytotoxicity was independently governed by: (i) the MPDL content – the lower the MPDL content, the greater the cytotoxicity; (ii) the nature of the linker – the presence of a labile diglycolate linker enabled a greater Gem release compared to a simple amide bond and (iii) the hydrophilicity of the methacrylate monomer-OEGMA enabled a greater anticancer activity to be obtained compared to MMA-based polymer prodrugs. Remarkably, the optimal structural parameters enabled reaching the cytotoxic activity of the parent (free) drug.

Maps that relate spectroscopic properties of a vibrational mode and collective solvent coordinates have proven useful in theoretical vibrational spectroscopy of condensed-phase systems. It has been realized that the predictive power of such an approach is limited and there is no clear systematic way to improve its accuracy. Here, we propose an adaptation of Delta-machine-learning methodology that goes beyond the spectroscopic maps. The machine-learning part of our approach combines Gaussian process regression used to generate the data set with an artificial neural network used to predict spectroscopic properties of interest. A specific application to the OH-stretch frequencies and transition dipoles of water is presented. Our method approximates these properties about two times more accurately than the spectroscopic-maps-only-based approach. Our results become useful in the study of vibrational spectroscopy of condensed-phase systems.

This study aimed to evaluate the effect of calcium ions (Ca2+) on the thermal gelling properties of cellulose nanocrystals-whey protein isolate composite gels, as well as to propose a corresponding ion-induced gelation mechanism. It was found that the gel strength, viscoelasticity, and thermal stability of the mixed gels gradually improved with an increase in the Ca2+ concentration from 0 M to 0.15 M. The addition of an appropriate Ca2+ could induce the conformational transformation from alpha-helix to beta-sheet, increase the content of tryptophan residues and reactive sulfhydryl groups, and enhance the hydrophobic interactions and the amide II band, which promoted the full unfolding and orderly aggregation of protein molecules to form a stable three-dimensional gel network. However, 0.20 M Ca2+ resulted in the formation of a coarse gel structure with some irregular aggregates, thereby leading to the decreased water holding capacity and gel strength. This research offers a theoretical foundation for the design and development of novel composite food gels with various functional properties.

The ‘2R,4R’-2-aryl thiazolidine-4-carboxylic acid anilides (ATCAAs) were synthesized using cyanuric chloride (CC) as a clean and substoichiometric acid-amine coupling agent under optimized reaction conditions. The diesterphenol intermediate based mechanism is proposed and supported by spectral characterization of the intermediate. The single crystal X-ray structures of acid substrate (2R,4R)-3-(tert-butoxycarbonyl)-2-(2-methoxyphenyl)thiazolidine-4-carboxylic acid (3 a) and anilides (R)-tert-butyl 4-(2-fluorophenylcarbamoyl)thiazolidine-3-carboxylate (4 b), (2R,4R)-tert-butyl 2-(2,6-dichlorophenyl)-4-(m-tolylcarbamoyl)thiazolidine-3-carboxylate (6 b) confirmed the formation of chiral anilides. The synthesized library of anilides [(R)-tert-butyl 4-Aryl thiazolidine-3-carboxylate and (2R,4R)-tert-butyl 2-Aryl-4-Aryl thiazolidine-3-carboxylate] 4 a-6 f was screened for their in vitro anti cancer, neuronal and neuroprotective studies. The anilides 4 b, 4 g, 5 d, 5 h, 6 c and 6 f (where the aryl=2-fluorophenylcarbamoyl, 4-chlorophenylcarbamoyl, 2-methoxyphenyl, 2,5-dichlorophenylcarbamoyl, 2,6-dichlorophenyl, 4-chlorophenylcarbamoyl respectively)were found to be less cytotoxic towards N2 A, SHSY-5Y neuronal cell lines in their differentiated and undifferentiated forms, and also exhibited dose dependant anti-inflammatory properties for a possible identification towards neurodegenerative and inflammatory disorders.

The total synthesis of lycoricidine and narciclasine is enabled by an arenophile-mediated dearomative dihydroxylation of bromobenzene. Subsequent transpositive Suzuki coupling and cycloreversion deliver a key biaryl dihydrodiol intermediate, which is rapidly converted into lycoricidine through site-selective syn-1,4-hydroxyamination and deprotection. The total synthesis of narciclasine is accomplished by the late-stage, amide-directed C-H hydroxylation of a lycoricidine intermediate. Moreover, the general applicability of this strategy to access dihydroxylated biphenyls is demonstrated with several examples.
