Discovery of a new series of potent prostacyclin receptor agonists with in vivo activity in rat
摘要:
The design and synthesis of two closely related series of prostacyclin receptor agonist compounds that showed excellent human IP receptor potency and efficacy is described. Compounds from this series showed in vivo activity after SC dosing in the monocrotaline model of PAH in rat. (C) 2015 Elsevier Ltd. All rights reserved.

This invention relates to (isopropyl and tertiary butyl-amino-2-hydroxypropoxy)phenyl-3[2H]-pyridazinones which have .beta.-adrenoceptor antagonist activity.
The rhodium-catalyzedaddition of pyridazinones to terminalallenes furnished the corresponding branched N2-allylated products in good yields with high regio- and enantioselectivities. A broad functional group compatibility was observed, and assorted synthetic transformations of the N-allylpyridazinones led to the preparation of a small library of N2-functionalized pyridazinones.
