Method of constructing alpha-glucosidase inhibitor in three steps by taking imine as initial raw material

The invention relates to a method of constructing an alpha-glucosidase inhibitor in three steps by taking imine as an initial raw material. By taking (E)-N-butyl-1-(4-nitryl phenyl) methylenimine as areaction raw material, the alpha-glucosidase inhibitor is synthesized successfully through three reaction steps: carbonylation reaction, reduction reaction and sulfonation reaction.

Carbonylation Access to Phthalimides Using Self-Sufficient Directing Group and Nucleophile

Herein we report a novel palladium-catalyzed oxidative carbonylation reaction for the synthesis of phthalimides with high atom- and step-economy. In our strategy, the imine and H2O, which are generated in situ from the condensation of aldehyde and amine, serve as self-sufficient directing group and nucleophile, respectively. This method provides rapid access to phthalimides starting from readily available materials in a one-pot manner. Various phthalimide derivatives are constructed efficiently, including medicinally and biologically active phthalimide-containing compounds.

Chemoselective Deprotection of Sulfonamides under Acidic Conditions: Scope, Sulfonyl Group Migration, and Synthetic Applications

Chemoselective acidic hydrolysis of sulfonamides with trifluoromethanesulfonic acid has been evaluated as a deprotection method and further extended to more complex synthetic applications. In contrast to conventional troublesome sulfonamide hydrolysis, a near-stoichiometric amount of acid was found to be sufficient to bring about efficient deprotection of various neutral or electron-deficient N-arylsulfonamides, whereas electron-rich substrates provided sulfonyl group migration products. The deprotection method developed is fully selective for N-arylsulfonamides, and the possibility to discriminate among various different sulfonamides is demonstrated.

New insight into probe-location dependent polarity and hydration at lipid/water interfaces: Comparison between gel- and fluid-phases of lipid bilayers

Environment polarity and hydration at lipid/water interfaces play important roles in membrane biology, which are investigated here using a new homologous series of 4-aminophthalimide-based fluorescent molecules (4AP-Cn; n = 2-10, 12) having different lipophilicities (octanol/water partition coefficient-log-P). We show that 4AP-Cn molecules probe a peculiar stepwise polarity (ENT) profile at the lipid/water interface of the gel-phase (Lβ′) DPPC (1,2-dipalmitoyl-sn-glycero-3-phosphocholine) bilayer at room temperature, which was not anticipated in earlier studies. However, the same molecules probe only a subtle but continuous polarity change at the interface of water and the fluid-phase (Lα) DOPC (1,2-dioleoyl-sn-glycero-3-phosphocholine) bilayer at room temperature. Fluorescence quenching experiments indicate that solutes with different log-P values adsorb at different depths across DPPC/water and DOPC/water interfaces, which correlate with the polarity profiles observed at the interfaces. Molecular dynamics simulations performed on eight probe-lipid systems (four in each of the DPPC and DOPC bilayers-a total run of 2.6 μs) support experimental results, providing further information on the relative position and angle distributions as well as hydration of probes at the interfaces. Simulation results indicate that besides positions, probe orientations also play an important role in defining the local dielectric environment by controlling the probes' exposure to water at the interfaces especially of the gel-phase DPPC bilayer. The results suggest that 4AP-Cn probes are well suited for studying solvation properties at lipid/water interfaces of gel- and fluid-phases simultaneously.

Azo-functionalized dendrimers

We report the synthesis of azo-functionalized Starburst polyamidoamine (PAMAM) dendrimers. The following three systems of azo-functionalized PAMAM dendrimers were prepared by different synthetic routes: (i) phenylazo derivatives; (ii) naphthalimide azo derivatives; and (iii) phthalimide azo derivatives. Model compounds in each system were synthesized for spectroscopic comparison. Confirmation of structure was achieved using a combination of NMR and IR spectroscopy to ascertain the functional sites (i.e., the azo and the cyclic imides), while mass spectrometry and UV-vis spectrophotometry were employed to ascertain the extent of functionalization. Substitution by the azo pendent groups increased the thermal stability of PAMAM dendrimers (TGA weight loss of the naphthalimide azo-functionalized PAMAM dendrimers up to 300°C, ca. 5%).

Glucagon antagonists/inverse agonists

Disclosed is a novel class of compounds of formula (I) wherein V, A, Y, Z, R1, E, X and D are as defined in the specification. These compounds act to antagonize the action of the glucagon hormone on the glucagon receptor. Owing to their antagonizing effect of the glucagon receptor, the compounds are suitable for treating or preventing glucagon-mediated conditions and diseases such as hyperglycemia, Type 1 diabetes, Type 2 diabetes and obesity.

Hydrophobicity-induced aggregation of N-alkyl-4-aminophthalimides in aqueous media probed by solvatochromic fluorescence

The fluorescence response of a series of n-alkanes of different chain length, all labelled with an environmentally sensitive fluorophore, is reported in aqueous media. It is shown that solvent-sensitive fluorescence properties of 4-aminophthalimide allow one to monitor subtle changes in the microenvironment of the fluorophore resulting from aggregation or self-coiling of the molecules. A new fluorescence that is observed in aqueous media for the higher homologues of the series has been unambiguously assigned to the aggregates of the molecules.
