Phenylpropenamide derivatives: Anti-hepatitis B virus activity of the Z isomer, SAR and the search for novel analogs

Phenylpropenamides have been reported to be a class of non-nucleoside inhibitors of the hepatitis B virus (HBV). This class of compounds was explored with the objective of developing potent anti-HBV agents, with a novel mechanism of action, that could be combined with nucleos(t)ide analogs currently used to treat HBV infection. To accomplish this objective a series of substituted arylpropenamide derivatives were prepared and the E and Z geometrical isomers were separated. The structural identity of each of the E and Z isomers was determined by single crystal X-ray crystallography. Contrary to previous reports, the activity of this class of molecules resides in the Z isomer. Further structure-activity relationship studies around the active Z isomer identified compounds that displayed potent antiviral activity against HBV with EC90 value of approximately 0.5 muM in vitro. Attempts to develop ring constrained analogs did not lead to active HBV inhibitors.

Regio- and stereo-selective synthesis of peracetylated carbohydrate esters of aromatic fatty acid using p-toluenesulfonic acid as catalyst

This paper describes an efficient synthesis of carbohydrate fatty acid esters based on a highly stereo- and regio-selective esterification. The suitably protected glycosyl was esterified with stearic acid to give mainly the beta-anomer in good yield using p-toluenesulfonic acid as catalyst. The structures of these compounds were fully confirmed by 1H, 13C NMR, mass spectra and HRMS.

The non-coordinating anion 1,1,3,3-tetracyano-2-propoxy-propenide as an anion-pi donor in cis-diaquabis(2,2?-dipyridylamine)zinc and its cadmium analog: Luminescence properties, Hirshfeld analysis and central-atom induced polymorphism

The synthesis, structure and properties of cis-diaquabis(2,2?-dipyridylamine)zinc bis(1,1,3,3-tetracyano-2-propoxy-propenide), [Zn(H2O)2(2,2?-dpa)2][tcnopr]2, I, and its isomorphous Cd analog, II, are reported. These two coordination compounds were prepared through hydrothermal reactions of Zn(II)/Cd(II) acetate with potassium 1,1,3,3-tetracyano-2-propoxy-propenide (tcnopr??=?[(NC)2CC(OPr)C(CN)2]?) in the presence of 2,2?-dipyridylamine (dpa?=?C10H9N3) as a co-ligand. Both new compounds were fully characterized by elemental analysis, FT-IR spectroscopy, powder XRD and X-ray single-crystal diffraction. Single-crystal X-ray analysis has revealed that compounds I and II are isostructural containing octahedrally coordinated metal ions, and exhibit 3D supramolecular architectures, including multiple anion-pi interactions. Furthermore, the photoluminescence properties in the solid state at room temperature and Hirshfeld surfaces analysis to understand the packing have also been investigated in detail.
