TABLE 3

Comparison of PNU-69176E analogs for their ability to enhance [3H]5-HT binding to 5-HT2C receptors in membranes from HEK293 cells expressing the receptor

Test ligands share the core head group α -d-galacto-octopyranoside, methyl-7-chloro-6,7,8-trideoxy-6-[(2-piperidinyl)carbonyl]amino group, but each has a different alkyl substitutent at the 4 position of the piperidinyl group, or shares the dodecanamide group but with different head groups attached at the amine group.
