BMS-779788 is a LXR partial agonist with IC50 values of 68 nM for LXRα and 14 nM for LXRβ.

The LXR selective partial agonist BMS-779788 is identified with potent induction of ATP binding transporters ABCA1 and ABCG1 in human whole blood (EC50=1.2 μM, 55% efficacy)[2].

BMS-779788 induces LXR target genes in blood in vivo with an EC50=610 nM, a value similar to its in vitro blood gene induction potency. BMS-779788 is 29- and 12-fold less potent than the full agonist T0901317 in elevating plasma triglyceride and LDL cholesterol, respectively, with similar results for plasma cholesteryl ester transfer protein and apolipoprotein B[1]. In mice BMS-779788 displays peripheral induction of ABCA1 at 3 and 10 mpk doses with no significant elevation of plasma or hepatic triglycerides at these doses, showing an improved profile compared to a full pan-agonist[2].
