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.

2, 4‐Disubstituted phthalazin‐1(2H)‐one derivatives were synthesized via nucleophilic attack of N‐2 of phthalazin‐1(2H)‐one derivatives on different alkyl halides. In addition, reactive phthalazinone acetohydrazide derivative was utilized as a scaffold to synthesize different heterocyclic systems. The assigned structures for all the newly synthesized derivatives were confirmed on the basis of elemental
