Herein, a straightforward synthetic approach for the construction of phenanthridin-6(5H)-one skeletons is disclosed. The developed protocol relies on palladium catalysis, providing controlled access to a range of functionalized phenanthridin-6(5H)-ones in 59–88% yields. Furthermore, plausible reaction pathways are proposed based on mechanistic experiments.

Structure–activity relationship-guided development of retinoic acid receptor-related orphan receptor gamma (RORγ)-selective inverse agonists with a phenanthridin-6(5H)-one skeleton from a liver X receptor ligand
Retinoic acid receptor-related orphan receptors (RORs), which belong to the nuclear receptor superfamily, regulate many physiological processes, including hepatic gluconeogenesis, lipid metabolism, immune function and circadian rhythm. Since RORs resemble liver X receptors (LXRs) in the fold structure of their ligand-binding domains, we speculated that ROR-mediated transcription might be modulated by LXR ligands, in line with the multi-template hypothesis. Therefore, we screened our LXR ligand library for compounds with ROR ligand activity and identified a novel ROR ligand with a phenanthridin-6(5H)-one skeleton. Structure-activity relationship studies aimed at separating ROR inverse agonistic activity from LXR-agonistic activity enabled us to develop a series of ROR inverse agonists based on the phenanthridin-6(5H)-one skeleton, including a ROR gamma-selective inverse agonist.

Structural development studies of anti-hepatitis C virus agents with a phenanthridinone skeleton
A phenanthridinone skeleton was derived from our previous researches on thalidomide and retinoids as a multi-template for generation of anti-viral lead compounds. Structural development studies focusing on anti-hepatitis C virus activity afforded 5-butyl-2-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)phenanthridin-6(5H)-one (10) and 5-butylbenzo[b] phenanthridin-6(5H)-one(39), which showed EC50 values of approximately 3.7 and 3.2 mu M, respectively.
