Synthetic DAF-12 modulators with potential use in controlling the nematode life cycle

Dafachronic acids (DAs) are 3-keto cholestenoic acids bearing a carboxylic acid moiety at the end of the steroid side chain. These compounds interact with the DAF-12 receptor, a ligand-dependent transcription factor that acts as a molecular switch mediating the choice between arrest at diapause or p...

These compounds interact with the DAF-12 receptor, a ligand-dependent transcription factor that acts as a molecular switch mediating the choice between arrest at diapause or progression to reproductive development and adult lifespan in different nematodes. Recently, we reported that the 27-nor-Δ4-DA was able to directly activate DAF-12 in a transactivation cell-based luciferase assay and rescued the Mig phenotype of daf-9(rh50) Caenorhabditis elegans mutants. In the present paper, to investigate further the relationship between the structure of the steroid side chain and DAF-12 activity, we evaluated the in vitro and in vivo activity of Δ4-DA analogues with modified side chains using transactivation cell-based assays and daf-9(dh6) C. elegans mutants. Our results revealed that introduction of a 24,25-double bond on the cholestenoic acid side chain did not affect DAF-12 activity, whereas shortening the side chain lowered the activity. Most interestingly, the C24 alcohol 24-hydroxy-4-cholen-3-one (6) was an antagonist of the DAF-12 receptor both in vitro and in vivo. © The Authors Journal compilation © 2015 Biochemical Society.
