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

  摘要：

  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 mu M in vitro. Attempts to develop ring constrained analogs did not lead to active HBV inhibitors. (C) 2011 Elsevier Ltd. All rights reserved.

  Stereoselective reaction of tetramethyl ethynyldiphosphonate with diethyl 2-amidomalonates yielded Z-vinyldiphosphonates, namely Z-2-[1,2-bis(dimethoxyphosphoryl)-2-alkyl(aryl)amidovinyl]malonic acid diethyl esters. A possibility of cyclization of the amidomalonate fragment of the obtained alkenes with the formation of an oxazole-substituted Z-vinyldiphosphonate was shown.
