efforts toward the development of potent and highly selectivehistamine H(3) receptoragonists. We introduced various alkyl or aryl alkyl groups on the piperidine nitrogen of the known H(3)/H(4) agonist immepip and its analogues (1-3a). We observed that N-methyl-substituted immepip (methimepip) exhibits high affinity and agonist activity at the human histamine H(3) receptor (pK(i) = 9.0 and pEC(50) = 9
