Abstract

A series of cinnolines/quinolines was prepared and it was found that 4-phenyl-cinnoline/quinolines with either a 2',3' or 2',5'-disubstituted benzyloxy moiety or the 1-Me-7-indole methoxy moiety on the meta position of the 4-phenyl ring showed good binding selectivity for LXRbeta over LXRalpha. The LXRbeta binding selective modulators displayed good activity for inducing ABCA1 gene expression in J774 macrophage cell line and poor efficacy in the LXRalpha Gal4 functional assay. 26, 37 and 41 were examined for their ability to induce SREBP-1c gene expression in Huh-7 liver cell line and they were weak partial agonists.
