  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.
