4-Arylphthalazin-1(2H)-one derivatives as potent antagonists of the melanin concentrating hormone receptor 1 (MCH-R1)
摘要:
A novel series of 4-arylphthalazin-1(2H)-one linked to arylpiperidines were synthesized and evaluated as MCH-R1 antagonists. The results of an extensive SAR study probing the effects of substituents on the 4-arylphthalazin-1(2H)-one C-4 aryl group led to the identification of the 4-(3,4-difluorophenyl) derivative as a highly potent MCH-R1 inhibitor with an IC50 = 1 nM. However, further investigations showed that this substance has unacceptable pharmacokinetic properties including a high clearance and volume of distribution. (C) 2011 Elsevier Ltd.

proceeds through [Pd]‐catalyzed acylation and nucleophilic cyclocondensation with dinucleophilic reagents. This process was based on direct coupling with simple bench‐top aldehydes without the assistance of directing group and without activating the carbonyl group. The process is highly advantageous because it employs simple nitrogen‐based nucleophiles, and non‐toxic and readily accessible aldehydes as the
