Function-regulating pharmacophores in a sulfonamide class of glucocorticoid receptor agonists.

A class of α-methyltryptamine sulfonamide glucocorticoid receptor (GR) modulators was optimized for agonist activity. The design of ligands was aided by molecular modeling, and key function-regulating pharmacophoric points were identified that are critical in achieving the desired agonist effect in cell based assays. Compound 27 was profiled in vitro and in vivo in models of inflammation. Analogs could be rapidly prepared in a parallel approach from aziridine building blocks.
