Extended N6 substitution of rigid C2-arylethynyl nucleosides for exploring the role of extracellular loops in ligand recognition at the A3 adenosine receptor
摘要:
2-Arylethynyl-(N)-methanocarba adenosine 5'-methyluronamides containing rigid N-6-(trans-2-phenylcyclopropyl) and 2-phenylethynyl groups were synthesized as agonists for probing structural features of the A(3) adenosine receptor (AR). Radioligand binding confirmed A(3)AR selectivity and N-6-1S,2R stereoselectivity for one diastereomeric pair. The environment of receptor-bound, conformationally constrained N-6 groups was explored by docking to an A(3)AR homology model, indicating specific hydrophobic interactions with the second extracellular loop able to modulate the affinity profile. 2-Pyridylethynyl derivative 18 was administered orally in mice to reduce chronic neuropathic pain in the chronic constriction injury model.

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.
The present invention relates to a pyrimidine compound (I) useful as a pharmaceutical intermediate, to a process for preparing said pyrimidine compound, to intermediates used in said process, and to the use of said pyrimidine compound in the preparation of pharmaceuticals.
