A practical and scaleable synthesis of a novel nonsteroidal ligand for the glucocorticoid receptor A-224817.0 1A is described. The synthesis proceeds in seven steps starting from 1,3-dimethoxybenzene. The biaryl intermediate 5 was prepared by an optimized high-yielding and high-throughput Negishi protocol. The quinoline core 8 was constructed by using a modified Skraup reaction. The final product was obtained by a direct allylation reaction of lactol 10 with allyltrimethylsilane. The process was accomplished efficiently to produce 1A in 25% overall yield and >99% purity with simple and practical isolation and purification procedures.

A novel class of functional ligands for the human glucocorticoid receptor is described. Substituents in the C-10 position of the tetracyclic core are essential for glucocorticoid receptor (GR) selectivity versus other steroid receptors. The C-5 position is derivatized with meta-substituted aromatic groups, resulting in analogues with a high affinity for GR (K-i = 2.4-9.3 nM) and functional activity comparable to prednisolone in reporter gene assays of glucocorticoid-mediated gene transcription. The biological activity of these novel quinolines was also prednisolone-equivalent in whole cell assays of glucocorticoid function, and compound 13 was similar to prednisolone (po ED50 = 2.8 mpk for 13 vs ED50 = 1.2 mpk for prednisolone) in a rodent model of asthma (sephadex-induced eosinophil influx).
