  Design, Synthesis, and Biological Evaluation of Triazolo-pyrimidine Derivatives as Novel Inhibitors of Hepatitis B Virus Surface Antigen (HBsAg) Secretion

  摘要：

  The high levels of hepatitis B virus (HBV) surface antigen (HBsAg)-bearing subviral particles in the serum of chronically infected individuals play an important role in suppressing HBV-specific immune response and are only mildly affected by the current small molecule therapies. Thus, a therapy that specifically reduces HBsAg serum levels could be used in combination therapy with nucleos(t)ide drugs or permit therapeutic vaccination for the treatment of HBV infection. Herein, we report the design, synthesis, and evaluation of novel triazolo-pyrimidine inhibitors (1, 3, and 4) of HBsAg cellular secretion, with activity against drug-resistant HBV variants. Extensive SAR led to substantial improvements in the EC50 of the parent compound, 5 (HBF-0259), with the best being 3c, with EC50 = 1.4 +/- 0.4 mu M, SI >= 36. The lead candidates, both la (PBHBV-001) and 3c (PBHBV-2-15), were well-tolerated in both normal and HBV-transgenic mice and exhibited acceptable pharmacokinetics and bioavailability in Sprague-Dawley rats.

  The chiral monoaza-15-crown-5 lariat ethers annellated to methyl-4,6-O-benzylidene-α-D-glucopyranoside- (1) or – mannopyranoside (2) used as phase transfer catalysts in the Michael addition of 2-nitropropane to substituted chalcones and chalcone analogues resulted in a significant asymmetric induction. The type of substituent on the chalcone molecule was found to have a significant influence on both the chemical yield and the enantioselectivity of the reaction: 24 novel chiral Michael adducts were prepared in 14-68% ee. These ee values were somewhat lower than that experienced in the case of the unsubstituted chalcone (85% ee). In the series of chalcone analogues, the 1-naphthyl Michael adduct was formed in 87% ee. Using glucose-based crown ether 1, formation of the (+)-enantiomers was preferred, while applying mannose-based 2 as the catalyst, the (-)-enantiomers were in excess.

  A one-pot acid-catalyzed tandem reaction has been developed without any metallic reagents or extra oxidants. This reaction involves a CC bond cleavage of enones via a “masked” reverse Aldol reaction, and C(sp3)–N bond cleavage of primary amines to provide nitrogen sources for the assembly of pyridine derivatives in high yields with excellent functional group tolerance.

  AbstractA highly regioselective synthesis of β‐aryl enaminones and 1,4,5‐trisubstituted 1,2,3‐triazoles from chalcones and benzyl azides based on reaction solvent selection is reported. In the presence of a catalytic amount of Ce(OTf)3, reactions of chalcones with benzyl azides in DMF at 100 °C afforded densely substituted Z‐β‐aryl enaminones in good to excellent yields, whereas treatment of chalcones with benzyl azides in toluene at 100 °C selectively produced 1,4,5‐trisubstituted 1,2,3‐triazoles in excellent yields.magnified image
