Compounds of formula (I) are useful in treating conditions or disorders prevented by or ameliorated by histamine-3 receptor ligands. Also disclosed are pharmaceutical compositions comprising the histamine-3 receptor ligands and methods for using such compounds and compositions. X is O, S, NH, or N(alkyl); Y, and Y' are each independently selected from the group consisting of CH, CF, and N; Z is C or N, provided that when X is O or S, Z is N; one of R1 and R2 is selected from the group consisting of aryl, heteroaryl, and heterocycle; the other of R1 and R2 is selected from the group consisting of hydrogen, alkyl, alkoxy, aryl, cycloalkyl, halo, cyano, and thioalkoxy; R3 is absent when Z is N and, when present, R3 is selected from the group consisting of hydrogen, methyl, alkoxy, halo and cyano; R4 and R5 are each independently selected from the group consisting of alkyl, haloalkyl, hydroxyalkyl, alkoxyalkyl, cycloalkyl, and cycloalkylalkyl, or R4 and R5 taken together with the nitrogen atom to which each is attached form a non-aromatic ring L is -[C(R15)(R16)]n-; m is an integer from 0-3; and n is an integer from 2-3.
or a pharmaceutically acceptable salt, ester, amide, or prodrug thereof, wherein:
X is O,S,NH,or N(alkyl);
Y, and Y' are each independently selected from the group consisting of CH, CF, and N;
Z is C or N, provided that when X is O or S, Z is N;
one of R1 and R2 is selected from the group consisting of aryl, hetereoaryl, and heterocycle.
