16919461-0	2006	Novel potent neuropeptide Y Y5 receptor antagonists: synthesis and structure-activity relationships of phenylpiperazine derivatives.	phenylpiperazine	103-119	neuropeptide Y receptor Y5	Homo sapiens	28-39	
16919461-1	2006	A series of phenylpiperazine derivatives were synthesized and evaluated for their neuropeptide Y (NPY) Y5 receptor antagonistic activities.	phenylpiperazine	12-28	neuropeptide Y receptor Y5	Homo sapiens	82-114	
16919461-3	2006	Subsequent optimization of the phenylpiperazine template by substitution of the phenyl moiety resulted in a series of (2-methanesulfonamidephenyl)piperazine derivatives that showed potent binding affinity and antagonistic activity for the Y5 receptor.	phenylpiperazine	31-47	neuropeptide Y receptor Y5	Homo sapiens	239-250
