  Synthesis and biological evaluation of ticagrelor derivatives as novel antiplatelet agents

  摘要：

  Ticagrelor (1) is the first reversible P2Y12 receptor antagonist blocking adenine diphosphate (ADP)-induced platelet aggregation with rapid onset and offset of effects. In this study, synthesis of ticagrelor and its derivatives has been accomplished in a convergent way. The compound design was based on modifications of ticagrelor and its major metabolite (33) in order to ameliorate their pharmacokinetic properties and dosing profile. The final compounds (1a-g, 35a-g) were evaluated for their inhibitory effect on ADP-induced platelet aggregation in rats. The assay results showed that some compounds (e. g., 1b, 1d, 33, 35b, 35f) exhibited comparable potency with that of ticagrelor. (C) 2012 Elsevier Ltd. All rights reserved.

  Provided herein are novel processes for the preparation of phenylcyclopropylamine derivatives, which are useful intermediates in the preparation of triazolo[4,5-d]pyrimidine compounds. Provided particularly herein are novel, commercially viable and industrially advantageous processes for the preparation of a substantially pure ticagrelor intermediate, trans-(1R,2S)-2-(3,4-difluorophenyl)-cyclopropylamine. Provided further herein are novel acid addition salts of trans-(1R,2S)-2-(3,4-difluorophenyl)-cyclopropylamine, and process for their preparation. The intermediate and its acid addition salts are useful for preparing ticagrelor, or a pharmaceutically acceptable salt thereof, in high yield and purity.
