Novel Synthesis of the Hexahydroimidazo[1,5b]isoquinoline Scaffold: Application to the Synthesis of Glucocorticoid Receptor Modulators
摘要:
The first stereoselective synthesis of the hexahydroimidazo[1,5b]isoquinoline (HHII) scaffold as a surrogate for the steroidal A-B ring system is described. The structure - activity relationships of the analogs derived from this scaffold show that the basic imidazole moiety is tolerated by the glucocorticold receptor (GR) in terms of binding affinity, although the partial agonist activity in the transrepressive assays depends on the substitution pattern on the B-ring. More importantly, most compounds in the HHII series bearing a tertiary alcohol moiety on the B-ring are either inactive or significantly less active in inducing GR-mediated transactivation, thus displaying a "dissociated" pharmacology in vitro.
