P4 and P1' optimization of bicycloproline P2 bearing tetrapeptidyl alpha-ketoamides as HCV protease inhibitors.

Abstract:

:With the aim of improving HCV protease inhibitors reported in our previous manuscripts, we synthesized and evaluated a series of 1a-based tetrapeptidyl alpha-ketoamides with additional P4 modification. The promising analog discovered through this SAR, 5a, was further derivatized at P1' or P1 position. As a result of these efforts, we found that replacement of the P4 valine as seen in 1a with cyclohexylglycine (Chg) resulted in the discovery of 5a, 5c, and 5e endowed with improved cellular activity in comparison to 1a.

  • A method for the synthesis of an oseltamivir PET tracer.

    abstract::A protocol applicable for the synthesis of an oseltamivir positron emission tomography (PET) tracer was developed. Acetylation of amine 3 with CH(3)COCl, followed by deprotection and aqueous workup, produced oseltamivir 4 from 3 within 10 min. The obtained 4 was sufficiently pure for PET studies. This method can be ex...
